Question [TB138FC-SD870] XiaoXin Pad Pro 2022 Sharing and support

[fry_35]

Maybe we can try the ROM of this model Lenovo Tab P12 Pro Xiaoxin (TB-Q706F)?

The QC is 30W and not 68W, maybe it will be an issue...

Unfortunately, according to the ZUI 14 update, it had abandone the PC Mode within the internal display. It will only appear on the external display that you connect through the Type C. But, during then, your internal screen will still not in PC mode. I was requested feedback to Lenovo on this and request to have that feature back. You should do the same...

Have you tried activating desktop mode using key options as shown in this link https://www.androidsis.com/iw/taskbar-modo-escritorio/ and in this one https://androidayuda.com/iw/asi-puedes-activar-modo-escritorio-android-q/

Hi! A new Lenovo Xiaoxin Pad Pro 2022 (SD870, model TB138FC) user here.
What is latest update? I tried to connect VPN to China but did not find any update. (My tablet is running 14.0.625)
I have already installed Google account (followed the highlighted steps), everything seemed perfect, but it turned out the tablet does not recognose any 5 GHz wifi network, and connected to the 2,4 GHz network through Wi-Fi 4 protocol. How can I check wether it is a warranty issue or a simple set up problem?

This device - since it is from China - uses different 5GHz channels than the ones your router is providing. Thus, it does not see any of your 5GHz SSIDs.

I am also at 14.0.625 right now. I also tried to update using the CN VPN but no luck. So we might be at the latest version.

Same here. SD870 2022 version on 14.0.025.

Seems very stable after 3 days of use. Never once crashed.

Only thing lacking is the productivity mode.

Hello @tonychua!
Thnaks for your feedback! Do You think, do You know any solution to change the wifi channel set up in order to use the European "standerd" channels and thus the wifi routers?
Since the tablet is not capable for mobile data transfer I'm thinking to purchase a wifi hotspot and/or extender. Do You think it is worth to purchase a Chinese product whicj works with Chinese wifi chanell set up?
Thanks and regards, [email protected]

I believe that with the Chinese ROM, 5GHz channels from other regions will not work.

A Chinese wifi hotspot may work on your tablet's wifi but may not work with your region's mobile frequencies.

Thanks again! It seems that the European and Chinese 5GHz wifi chanells are complementary, opposite of each others. A Chinese ROM can work well with a wifi router (and its 5GHz chanells) set up for USA region. (I tested and my tablet recognise and work through WIFI 6 protocoll with a router set up for USA.)
Unfortunately my Telekom router is set for European region and can not be changed/modified.

What channels are supported in both the 2.4 GHz and 5GHz band in most countries?

The channels that are supported depend on the regulation in each country. Here is a summary of most countries:Indoor Use Only, Radar Bands (DFS band) Region 2400 to 2483.5MHz 5.15 to 5.25...

I have the exact same model and firmware as you. I notice the tablet was able to recognise the connection as 5Ghz automatically.

Did you manage to make a google account, or did you manage to make a global rom?

This was with the ZUI14 ROM.

This is for Android 13. We are currently on Android 12 with ZUI14 at the moment.

I did not face any WIFI 5G issue with different router so far. The competibility could be the issue...

The current firmware is 14.0.625. there wasn't any OTA for higher rev no, yet.

Has anyone had success in using the Smart Split - the same application, dual screen display function?

Seems like a good feature where you can have 2 different view of the same app.

Have no luck in activating the feature so far.

This was with the ZUI14 ROM.

I didn't understand, what did you do with ZUI 14, the global ROM or creating a Google account?

 

[Good Man1]

This is for Android 13. We are currently on Android 12 with ZUI14 at the moment.

I think it appears in those links that it is supported from Android 10.

Try the Taskbar app from the Google Play Store, I think among the other things it offers there is also what you want.
Let me know if it helped you.

I have active pen 3 and not working with this model

The tinting also differs between 60Hz and 120Hz. Green tint on 120Hz 25% brightness.

You are right. I notice the greenish tinting at 120hz. When I switch to 60hz, the green tinting disappear.

It is particularly obvious while watching Netflix with dark scene at 120hz. Black look crushed + green tint on specific area of the screen. It is as if the backlight were turned on by error and produces the green tint.

Hope lenovo acknowledges this flaw and fix it via software update!

Hi all

I have received this tablet and encountering display tearing, it's like the display is "cut" in half,
and the updates are delayed between the two halves, if that makes any sense...

Do you think this is a software / firmware problem, or is it an obvious hardware problem?

It's just that I'm not sure whether or not this was happening when I originally received the tablet (which firmware was 2 versions prior to the latest one), or since I have updated it to the latest OTA firmware. (14.0.625)

I tried to reset the tablet and that didn't help, I thought maybe reflashing the firmware if that's a software problem...?

Thanks for any advice!
