Hey there, sorry to jump in but thought it better than starting a new thread for 1 query.

I'm happy enough with the eng/chn ROM but I can't find a way to set up multiple users. Any tips?

Cheers

Yes and its the main reason I'm moving to P12 Pro. The screen is junk at low light or near black. Bright films no issue, as soon as you watch a dark film it really exposes it.
I suspect its the reason the tablet wasn't sold internationally. Good luck charging $600 for that outside of China.
I'm surprised the YouTube reviews don't pick up on it.

So it is cheap OLED and not compared to Samsung AMOLED, My friend told me that he sold the xiaoxin tablet and bought Tab S7, He said that the IPS screen of Tab S7 is far better than xiaoxin tablet even in dark scenes
 
Agreed but the same scenes which look bad on the tablet look fine on my B7 oled.
Normal. Las oled de LG llevan procesadores como las Sony, Panasonic y demás para corregir los problemas de las pantallas oled en bruto. Y dichos procesadores eleminan temas como el banding o corrigen ese desfase entre el pixel apagado y el pixel al mínimo. Pero he visto pelis 2160p hdr en esta tablet y esa sí es la medida de la pantalla en cuanto a la calidad que puede dar

Everything I watch is 4k HDR or Dolby Vision 20/30Gb file size via plex. So I'm giving it absolutely the best chance.

The screen shot earlier shows a very clear dirty screen affect. I can make it show up easily using a YouTube video for burn in. I was in a store today looking at the same video on a Samsung S7+ and could not recreate the issue.

I'm confident it is the quality of the 2021 models panel and not an inherent flaw in oled (although I don't disagree with your point entirely).

Ether way in about 2 days I will do a side by side comparison and post the results.

I've been curious about these reports of poor quality low light screen uniformity issues. The display quality on the one I just received is stunning.
I just ran various test videos from YouTube designed to test oled uniformity and the panel is absolutely consistent on every test, absolutely no uniformity issues, or any discernable patterns, lines, marks, steaks, shadows or screen burn patterns etc.
I'm wondering if some of these tablets might have a bad batch.

Try an all grey screen at low brightness

I did, I tried several different levels of grey from barely perceptible not black, through to light grey, I still couldn't get anything but very smooth, grey. Maybe I didn't have the brightness down enough, I'll try again and see.
It is most obvious to me in low light (or a pitch black bedroom) with the brightness slider on down low. It will even show on this XDA website. I really hope they were a bad initial batch as the 2021 11" is fantastic value.

The difference between the Pentile and AMOLED screen is highlighted in this video:

i just re-ran the test in complete darkness and can now see some uniformity issues in those low greys. I'm not sure it's going to be a problem for us as it will be mostly used during the day, and the issues are invisible with any normal level of lighting. It is a shame though I agree, as those issues just shouldn't be there at all on an oled.

I watch a lot of TV films in bed and my Mrs is asleep so the light is off so it really did bug me. It manifests itself in loss of detail in low light scenes. I agree in your usage case it'll be less of an issue.

the only thing ive noticed so far, havent used it alot mind you, is chrome when you at the page before you open a tab looks bad, but when your loading a app the pure black looks top notch..

so anything with grey in looks bad?
In some scenarios yes. But for the money the 11" 2021 is hard to beat! 90Hz oled and SD870 SOC!! Amazing value.

I'd even be happy with the £510 I paid for the 12.6" if there weren''t so many software gremlins. It seems perfection is hard to achieve for Lenovo?

    When did I say it wasn't bright? Both panels have perfectly acceptable brightness levels.

    I have spent more time with my 2021 Pad Pro as my 12.6 had to go back to China for a reflash.
    In that time i've established a few things.

    The dirty screen effect is an issue but not one I see day to day anymore.

    The biggest problem I was encountering was the black crush in dark scenes of films. I've actually found out what the issue is. I use JustPlayer for all my content as it will play all HDR containers inc Dolby Vision. What I was noticing is the video plays fine for about 1 to 2 seconds then the brightness/contrast changes and it is at this point that the images turns to trash. I have discovered if I set the screen to 60Hz this no longers occurs.
    Since i've made this change when watching media i'm actually pretty pleased with the Pad Pro 2021 and value wise it is absolutely the best tablet on the market.

    However... The E4 panel in the 12.6 is hands down better in all scenarios to my eyes. In high bitrate files around red objects the 11" would look pixelated and distorted. (I will try and capture this). This does not occur on the 12.6, I also found the 12.6 to be brighter in HDR.

    Colour vibrancy (with all settings between the two tablets equal) the E4 panel is greatly increased. Images and video pop much more.

    Pentile or otherwise the 12.6 screen is sharper. I don't know why as the PPI is actually lower on the 12.6 but it is clearly (excuse the pun) sharper.

    I should be getting it back tomorrow. I'll try and capture some of the examples (if possible) side by side.

    Something to note, it seems your comparing a Samsung S6 E4? I belive even the S7+ has a dimmer panel than the e4 in the Pad Pro 12.6 (P12 Pro) so your results although interesting are not valid against this newer tablet imo.
    It was the message in between yours #13 that referred to low brightness, (my bad).
    as sustained +600nits certainly ain't too shabby on an OLED-based tablet.
    I am able to go a tad higher on Samsung E4 1600p AMOLED panel, but only if I flood the light-sensor and trigger the short sunburst-effect.
    but as a plain slider brightness (sustained), the Xiaoxin actually goes higher than Samsung on the brightness slider.
    If you can try to measure the brightness on the P12pro.
    I don't know if you got a bad batch on your P11pro2021 and, your definitely not alone with the phrase "Pentile display" - many reviewers on YT.. uses that phrase on this Xiaoxin but when asked under their videos' if they actually know what pentile display is and why they conclude that its a pentile display on the Xiaoxin, . its mostly silence or "I have heard it from another YT'er".

    btw, I also have an LG 2017 4K OLED (55"), so that black crushing you are referring to, I would be able to replicate if you show some examples.
    Here is a WOLED grid on that 2017 4K LG OLED.
    precarious that LG's 4K WRGB OLED grid arrays still only let 3 of the 4 WRGB subpixels be lit a once. (not sure if that limitation is still the case on the newer WRGB OLED panels for TVs from LG display, but I reckon it is)
    - below macro is at the same resolution as on the Samsung E4 1600p AMOLED and the 1600p OLED macro view in the above-posted vid, so it gives a good indication of how big the WRGB is OLED pixels are on these 4K TVs in regards to the OLED RGB pixels on tablets.

    I haven't noticed any black crushing on my Xiaoxin and also have access to two Samsung E4 OLED panels.. the 10.5" 1600P in fx Tab S6 and the 12.4" in Tab s7+.. not sure what panel are in the P12pro as that one is obviously bigger 12.6" then S7+ that is 12.4" but it is labeled as an E4 AMOLED so same gen as the 10.5" and the 12.4"
    as mentioned some things the Xiaoxin 1600p OLED panel does better then Samsung E4 gen with its blue stripe AMOLED, and in some aspects, the Samsung does better.
    fx if I put a test pattern with very fine lines beside each other.. I see more dirty screen effects on the Xiaoxin than I do on the Samsung E4 panel.

    If you can' try and take the app "Screen test pro" on both and go into screen color test and put the brightness slider on max with the setting "brightness enhancement" active and do the same on the P12pro, and take a side by side picture.
    If you see the same effect, on the P12pro 12.6" E4 AMOLED panel, as I do and they are worse in reproducing "red", than the OLED panel in Xiaoxin.
    here is a 10.5" 1600p Samsung AMOLED panel on the left, found in fx the 2020 flagship S6 and Xiaoxin 11.5" 1600p OLED on the right both with the app screen test pro and color slides.
    Samsung E4panels often choke into orange.



    I also wondered about the p12pro as that unit was up for sale' when I went for Xiaoxin p11pro, though the p12pro keyboard and accessories like stylus were not present at that time.
    but in my mind, the p12pro made little sense as it was so much more expensive.
    I really didn't need another big Android tablet, now that all my older books also run Android, like Surface Book2 and the 2x Porsche Books,.. that are 13.5" and 7mm thin and weigh around 700g and works well as huge Android tablets, though sadly not OLED..

    The Xiaoxin P11pro2021 was facepalm good value around singles day and BF and still is and was actually very close to CN sale prices, so wicked good value not least here from Denmark with tax + 25% danish VAT, and often results in some of the world's highest consumer prices and overall livingcost.
    Fx on Lenovo DK official atm.. the older P11pro 730G 60HZ from 2020 cost from 4299 DKK (+655 USD) and thats the base wifi entry version 128GB, so quite high prices here on somewhat dated 2020 hardware, when the older 2020 variant is almost double the price of the P11pro2021.

    Also wondered about the Mi pad5 and the Mi pad5pro and were close to take the plunge on the Mi pad5 when that unit was on early bird-sale at 299Euro - and glad I didnt as that is almost the same price as what you could get the P11pro2021 for at these singles day or BF sale, - and I certainly prefer the keyboard-cover for the Xiaoxinp11pro2021 with the trackpad and the magnetic kickstand where Mi pad5 (and also its Pro version) uses that grove-variant. without any trackpad.
    Went for the P11pro2021 and the keyboard (both from Giztop) and the folio-cover from Lenovo Denmark as they had it for around 16 euro with free shipping (seems it comes from England) and that was less. then what I could find it at' from abroad.

    btw does any of yours P11pro2021 weigh the claimed 485g.. mine is 492g.

    To make it clear, the Samsung Tab 7+ uses a 12.4". E4 AMOLED panel. the Samsung Tab S6 (Samsung 2020 flagship) is the same also an E4 AMOLEDbut in 10.5".
    The Xiaoxin P12pro. is 12.6" so a tad bigger than the S7+ panel, but P12pro is also on the old E4 panel, so pretty sure you will get the same results, as the other E4 blue-stripe AMOLED panels found in S6 and S7+.
    also why I referred to testing fx an all-red slide on max brightness' when you have both devices P11pro2021 and P12pro, as the E4 AMOLED-grid array's red-subpixels is a tad smaller' than the red subpixels in the Xiaoxin (see the first video in #131), and could be why the red-colors are worse on Samsung's E4 AMOLED panels. (more orange tone)

    Samsung is just now finally elevating to a new generation of AMOLED panels (finally).. their so-called E5 generation, but as I wrote above. I don't know if the new Tab S8+ and Tab S8ultra that are about to land in 1q 2022 is with that new generation of E5 AMOLED panels, though it would surprise me if it ain't.

    I have had some problems with the charging on my unit.. where it will not charge and just give a message "cant charge right now" and you are quite puzzled.. as it doesn't give any explanation, and you left with a ??.. okay tablet, but when does it then suit you to charge.!!

    I hard-rebooted mine, and then it charged fine but precarious experience..
    btw..it seems you have been able to take OTA updates without loosing your L1 .. is that the case for others, that are on the P11pro2021 native CN/ENG rom, or have other people lost that L1 widewine by using OTA?

    //
    I checked the display for use of DC dimming, and it indeed makes use of DC dimming.
    have waveform video on a Micsig ST1104C scope.
    Also noted a 144hz bug on the display setting front page (below) though havent installed any OTA updates so far, still, on the OS revision, it arrived with.

    I'm quite impressed with the sound-- out of the box. Its 4x JBL-labeled Atmos speakers don't sound good, it gets way better if you activate the "Atmos" feature, but my Samsung's AQK quad speakers still sound a tad better, but If I go into the 10-band Atmos EQ, I can get very close to the AGK Atmos quad-speaker quality from Samsung that IMO is the best on tablets these years. (certainly not bad quad-speakers in the Xiaoxinp11pro2021, but it takes a little work to finetune it in the Atmos 10band EQ)

    Also like Lenovo's landscape feature where it flips apps, to landscape-view, quite useful when you use keyboard and trackpad)
    Same with the swipe feature, and something I like a lot on Samsung tablets, where you can swipe from the sides, happy to see that on the Xiaoxin. but maybe it is a native feature on Android but quite useful..- same is the feature to jump between current apps you have open, by making a half-circle from below..

    The microSD card reader supports up to 1TB, and I tried to test the speed with one of these cheap new Aliexpress Samsung cards-
    It seems to max out just under 90MBs read and just under 80MBs write. (128GB Samsung Evo+ white)
    also tried with one of the other in Samsung's new line micro SDcard.. the blue Samsung pro 256GB, and it was the same speeds on the Xiaoxin p11pro2021, so it seems to be the max.
    IMO the new Samsung Evo+ (white version). more or less same as the old Evo+ (red) and the new Samsung Pro blue, it matches my Sandisk extreme pro when testing on laptops.
    Samsung does label this blue Samsung Pro with 160MB read and 120MB write but was not able to get those readings, on a thunderbolt3 TypeC port on Porsche Book with a TypeC 3.0 pr 3.1 SD card reader.. perhaps if I use a USB3.2 reader, though, at around 45USD delivered for 256GB with incl. danish 25%VAT, it's not a bad value these blue Samsung Pro cards with MicroSD card speeds around Sandisk extreme pro.
    but the Samsung Evo+ (red or the white version), is still the best bang for the buck MicroSD cards as those you can get at around 15USD.

    Audio codecs

    The cameras are nothing to write home about, it got 4, two in the back and two in the front..but I don't know which CMOS sensors Lenovo is using, but the Lenovo camera app is utter garbage and third-party apps didn't seem to elevate any higher res on video then the 1080p30 that is low (2mpix) for a 13mpix sensor..
    So Its a mixed bag, and the overall Lenovo software and the camersa, leave a lot to be desired, but all the other things..gives a flagship vibe, and with the price in mind, its in my view the best bang for the buck Android tablet - in the second half of 2021.

    I hope OS13 is being channeled through the OTA channel, at a given point and not only as a manually install..

    The difference between the Pentile and AMOLED screen is highlighted in this video:

    It's not a pentile display in Xiaoxin P11pro2021 as it has an equal amount of RGB subpixels, been debating this with Ron Meters owner of OLED-info org.
    Pentile display is useally a Samsung trickery, where they often will put more of certain subpixels to elevate certain things.. also why "Pentile" is a Samsung trademark...
    fx if you have 2 green subpixels for each red and blue..

    None of these (Samsung E4 or Xiaoxin 1600p OLED) are pentiles displays as per-say..
    Weird how people are running around with that line, and likely have no idea what a pentile display is.

    Been comparing the Xiaoxin 1600p RGB OLED versus a gen E4 1600p AMOLED and it's a mixed result and some does the Xiaoxin better and some does Samsung AMOLED better, but to summon it's certainly not a bad 11.5" OLED display Lenovo er using when you have the price in mind, quite the contrary.
    in some tests, the Xiaoxin 1600p RGB OLED actually outperforms the Samsung 1600p AMOLED.
    fx the ability to recreate "red".. here I at times often sense the Samsung E4 are tilting into orange, and not sure if it's down to a tad smaller "Red" subpixels versus the Xiaoxin 1600p.

    You can see here where I put both displays under a 4K macro view.
    a gen E4 s AMOLED 1600p display (blue s-stripe variant) and the Xiaoxin at around 50sec.

    here with some colorslides
    also not sure why you're claiming it ain't bright for an OLED.. I'm getting above +600nits on my unit, and that's only with the slider and the max brightness setting activated in settings... quite solid, though the P11pro2020 60HZ panel could be lower, as Notebookcheck saw way less in their review, though I don't recall they have had a look at the P11pro2021 (SD870 90Hz).

    Samsung is just about to release products with their new-gen E5 AMOLED panels, though I don't know if those will be the case with the coming tab S8+ and their behemoth tab S8 Ultra

    Here are some color slides at the end' and how the Samsung AMOLED subpixels on their blue-stripe panel, often choke in certain full-color slides, mainly all red. (1:50 below) and toogles into a an orange tone while the Xiaoxin is able to keep it together' - a tad better..

    I have had some problems with the charging on my unit.. where it will not charge and just give a message "cant charge right now" and you are quite puzzled.. as it doesn't give any explanation, and you left with a ??.. okay tablet, but when does it then suit you to charge.!!

    I hard-rebooted mine, and then it charged fine but precarious experience..
    btw..it seems you have been able to take OTA updates without loosing your L1 .. is that the case for others, that are on the P11pro2021 native CN/ENG rom, or have other people lost that L1 widewine by using OTA?

    I checked the display for use of DC dimming, and it indeed makes use of DC dimming.
    have waveform video on a Micsig ST1104C scope.
    Also noted a 144hz bug on the display setting front page (below) though havent installed any OTA updates so far, still, on the OS revision, it arrived with.

    I'm quite impressed with the sound-- out of the box. Its 4x JBL-labeled Atmos speakers don't sound good, it gets way better if you activate the "Atmos" feature, but my Samsung's AQK quad speakers still sound a tad better, but If I go into the 10-band Atmos EQ, I can get very close to the AGK Atmos quad-speaker quality from Samsung that IMO is the best on tablets these years. (certainly not bad quad-speakers in the Xiaoxinp11pro2021, but it takes a little work to finetune it in the Atmos 10band EQ)

    Also like Lenovo's landscape feature where it flips apps, to landscape-view, quite useful when you use keyboard and trackpad)
    Same with the swipe feature, and something I like a lot on Samsung tablets, where you can swipe from the sides, happy to see that on the Xiaoxin. but maybe it is a native feature on Android but quite useful..- same is the feature to jump between current apps you have open, by making a half-circle from below..

    The microSD card reader supports up to 1TB, and I tried to test the speed with one of these cheap new Aliexpress Samsung cards-
    It seems to max out just under 90MBs read and just under 80MBs write. (128GB Samsung Evo+ white)
    also tried with one of the other in Samsung's new line micro SDcard.. the blue Samsung pro 256GB, and it was the same speeds on the Xiaoxin p11pro2021, so it seems to be the max.
    IMO the new Samsung Evo+ (white version). more or less same as the old Evo+ (red) and the new Samsung Pro blue, it matches my Sandisk extreme pro when testing on laptops.
    Samsung does label this blue Samsung Pro with 160MB read and 120MB write but was not able to get those readings, on a thunderbolt3 TypeC port on Porsche Book with a TypeC 3.0 pr 3.1 SD card reader.. perhaps if I use a USB3.2 reader, though, at around 45USD delivered for 256GB with incl. danish 25%VAT, it's not a bad value these blue Samsung Pro cards with MicroSD card speeds around Sandisk extreme pro.
    but the Samsung Evo+ (red or the white version), is still the best bang for the buck MicroSD cards as those you can get at around 15USD.

    The UFS3.1 system drive.

    Netflix specs.

    Antutu run.

    Audio codecs

    The cameras are nothing to write home about, it got 4, two in the back and two in the front..but I don't know which CMOS sensors Lenovo is using, but the Lenovo camera app is utter garbage and third-party apps didn't seem to elevate any higher res on video then the 1080p30 that is low (2mpix) for a 13mpix sensor..
    So Its a mixed bag, and the overall Lenovo software and the camersa, leave a lot to be desired, but all the other things..gives a flagship vibe, and with the price in mind, its in my view the best bang for the buck Android tablet - in the second half of 2021.

    I hope OS13 is being channeled through the OTA channel, at a given point and not only as a manually install..

    Anyone answer me please
    Dear 3bo0od, I bought the Xiaoxin pro pad 2021 from Giztop last month (actually typing on it right now) and it has the China - translated English ROM on it. I can install all apps on it (Google, Play etc.) and now even use if for work (with all the Microsoft apps installed on it). The English translation is ok, but as a near-native English speaker there are some funny translations noticable.

    With regards to L1 for Netflix, I can confirm it runs HD quality on Netflix without issues. When I got it, it had 2 updates ready which I installed after 2 days of waiting. It simply updated Android and I still have L1 with Netflix. I will see if I can take a screenshot later.

    As a European user, I was tempted to buy the P12 European tablet (not sure if it is available already) due to the ROM and English-translation issues. But honestly, the tablet runs great and the price on Giztop was fine. Better than Banggood if you want the keyboard with it as well.

    We took a slight gamble getting a tablet with these specs for £350. It's not the end of the world. The OLED screen is OK. Bright scenes are fine but shadows are massively crushed and dark screen uniformity is horrendous. Also no global ROM with widevine level 1. No massive issue if your native language is English as the Chinese rom is totally fine.

    In hindsight you'd be better off trying to get a better deal on an Samsung Tab S7+ with better AMOLED screen and Native HDR support in nexflix.

    On this screen dolby Vison is no better than normal HDR. Losing to go the Samsung is no great loss.

    The P12 Pro with its Amold screen with chinese and global varient looks the safer bet.

    Yeah that's the 2020 version. We're talking about the 2021 version which does not have an international version.

    Ive been using this tab for a couple of days. The ROM is just a cleaned-up Chinese one, it has English language and gapps. However, the only major problem is that ZUI doesn't let apps from google store function in the background, as a result, all the messengers, e-mail apps, youtube, etc, basically all the apps that should notify you about anything don't do it. If you're working in the app and shortly after you've closed it - yes, you'll get a notification, but not after it has been cleared from the memory. It is not the first time a Chinese ROM behaves this way, so maybe anyone has some suggestions?
