Lenovo P2 bugs / issues

[The Mero]

Just thought i'd start a thread for owners of the P2 to share any bugs ( and hopefully cures ) that we've come across so far . And to tidy up other threads that may get clogged with these issues .

i've had mine now for just over 2 weeks and so far its been somewhat of a disappointment. The issues i've come across so far are ...

1 - Audio sync .. regardless of app used the audio sync is out with the video . It gets even worse when trying to steam a video through a web browser ( and i've tried a few different ones just to make sure its not a chrome issue ) . streaming audio from internet radio is bad too . After 20 minutes or so the sound breaks up completely .

2 - Low volume in recorded videos .. The noise suppression / noise cancellation kicks in within one second when you record a video . what sound you are left with is similar to an old gramophone record .

3 - Notifications .. Seems to be an issue with the phone going into deep sleep , no notifications come through . I've read a few people saying turning off app optimization for the affected apps helps , but i don't think it makes any difference .

4 - tap to wake .. tap the screen twice , sorry 22 times to wake up the phone .

5 - SD card formatting .. freezes every time i try to format a memory card ( which has worked perfectly in galaxy S5 ) as internal or external memory .

6 - high CPU usage at idle .. I've seen this on a few other forums too . cpu starts sticking at 1.6ghz after the phone has been running for a few days . I've done a clean wipe and installed no other apps or removed any and its still present .


And the most amazing thing is i haven't seen any of these issues raised in any reviews of the phone either

So feel free to add any comments or fixes if you come across them . This could be a fantastic phone if only the gremlins are fixed .

And could you please state which firmware version your phone is running .. I'm on P2_056_uk

1,3,4 are the problems which i am also facing ..

Thanks for this post , and i have some points to add

7) "Ok Google" Hot word Doesn't work
- i have tried GoogleNow Launcher with all set, but sadly Google assistant fails to respond every time
8) Some times Gyroscope/ Accelerometer sensor goes bonkers
-i noticed that while i was playing Asphalt extreme game.. my Steering goes Out of control


finally a very bad thing which isn't a bug but annoying me a lot is -

i've got an app which does the function of DOUBLE TAP TO SLEEP , ( we can put the same in Novalauncher also, under gestures) This is using Accessibility service so when i use FINGER PRINT or any kind of SMART LOCK it always asks me to put my PATTERN LOCK even after keeping my finger across the sensor ..
and this is very disturbing.. as a result i had to disable FINGERPRINT unlock and use DOBULE TAP TO WAKE in which i again face problems .....huh...

if there is anyway to overcome it.. please suggest me a way

1) I have heard about that issue from quite a few user but i have never faced that issue.
2) Not recorded video much so cant say
3) Not facing this issue
4) Yup it works only 5 out of 10 times
5) Never tried
6) Haven't paid attention to the CPU usage

I confirm no. 3:
"Notifications .. Seems to be an issue with the phone going into deep sleep , no notifications come through . "
- I noticed that when i unlock the phone emails and notifications are being pushed. I am still bench-marking the battery and as soon as i have done a couple of cycles to get a feel of the battery life i get i
will try and play around with the battery optimization settings in the settings.

These are working fine with my mobile, Made in china one (i know there are 2 types available):
4 - tap to wake .. tap the screen twice , sorry 22 times to wake up the phone .
- Do you by any chance use a thick screen protector that might not register the double tap?
- I don`t actually use this feature as i have the finger print unlock feature active and I use that to wake the phone.
5 - SD card formatting .. freezes every time i try to format a memory card which has worked perfectly in galaxy S5 as internal or external memory .
- I formatted an older SD card from my Xioami phone in the Lenovo and had no issues (it warned me that it might be slower and suggested to get a faster one) but i had no issues.
- From my past experience (also outside mobile device use) SD cards are verry sensible, i had some of them die out of a sudden or not being readable across devices.

Possible new bug, sometimes switching from Wifi to GSM or back i noticed i had no data connection, after toggling Airplane mode on and off it works fine.
Only noticed it once so take it with a grain of salt.

Interference noise when using headphones

When listening to music via headphones there is lots of electrical interference type noise. If I turn volume to zero it stops. It also stops once no sound is being fed to the headphones. Turning the volume up helps to drown the noise out. It's there between tracks most noticeably but also very audible when trying to listen to relaxation music at very low volume which I do a lot of to help me sleep.

It sounds like processor interference of some sort - beeps and electrical sounds but also machine gun 'pips'.
I have discovered that Bluetooth being on makes it WAY worse. If it is switched off it is barely audible - but still there. I need bluetooth on all the ktime for my smartwatch.

It happens on all apps: Spotify, Netflix, YouTube etc. I even hear it when I get notifications.

Anyone else noticed this issue. Would you mind testing for me??

Oh re. the OP numbered issues:

1. I also get the audio sync issue but only on Youtube. Netflix, Amazon Video etc are fine for me.

2. My video's audio is fine so far.

3. Not had phone long enough to notice for sure but I have had notifications come through when it's asleep.

4. Tap to wake worked well for me but I turned it off.

5. I have had real problems with my micro SD cards too. My first card, the P2 said it was faulty or damaged and gave me the option to reformat it. It got to 20% and then the phone completely locked up with a black screen. I had to remove the card to get the phone working again. After that the card is toast and unreadable on any device. The card was fine in my previous phone.

Second card I tried I successfully formatted in the P2. However, after 24 hours without issue, the P2 is now reporting that the card is 'unsupported'?!

My device has a screen flicker problem, occasionally the screen brightness change for a fraction of a second, even with the off auto brightness, other online users have reported this problem.

Other point :

3 - Notifications .. Seems to be an issue with the phone going into deep sleep , no notifications come through . I've read a few people saying turning off app optimization for the affected apps helps , but i don't think it makes any difference .

This is a Android doze scheme problem, you install a "disable doze" app from play store to solve this issue, or use adb method ( This problem is present on several models including the OnePlus 3 ), adb method is temporary untile reboot phone.

adb shell dumpsys deviceidle disable

6 - high CPU usage at idle .. I've seen this on a few other forums too . cpu starts sticking at 1.6ghz after the phone has been running for a few days . I've done a clean wipe and installed no other apps or removed any and its still present .

I confirm, CPU-Z shows all eight core at 1689 Mhz fixed frequency

Someone said the buzzing issue with headphones seemed to calm down when the screen turned off , could be causing interference , but i remember my old moto G2 had the same issue and buzzing stopped once music started playing ( even on very quiet parts of a song you couldnt hear it )

can you confirm the sync issue on BBC Iplayer too BritishBeef . And I tried the card in the galaxy S5 again , formatted straight away . I Forgot to say it was a 64gb sandisk ultra , only a few months old . The strange thing is The P2 created a 15mb partition and that was all the samsung could see , had to remove it and all ok again

Screen off makes no difference unfortunately. It's not a buzz though, it's popping, and electrical chirps and pips.

I think its some form of noise suppresion that kicks in once the music starts playing , very annoying all the same though

You know i'm starting to wonder if the phones actually made by lenovo , awful lot of similarly specced devices coming out of china at the mo

Forgot to say if anyone comments could you also say which firmware version you have too .. I dont think the bugs are firmware specific , but its good to see if they are present in any updates

Unable to for now I'm afraid as I have packaged it up to return it. Going to get another one but buy it in a store this time. I bought the original online from Three (UK) and just spent 90 minutes on the phone to an Indian call centre to arrange a return. One of the most painful calls of my life

 

[The Mero]

I wonder how many returns 3 have had so far ???

I bought mine free of contract from an online shop, unbranded and unlocked.
Currently am on the latest build number available, P2a42_S062_170117_ROW.
Ran also CPU-Z and my CPU usage is when i start the app for 1 second at 1.6Ghz then goes down to 652Mhz, so no issues for now.

hi, i have problem with the NFC...
apparently he is really very little sensitive and i cant use it on my bluetooth headset but bluetooth work fine if i connect it manually...
Same issue with my SRS-X77 but I manage to make it work with a lot of patience...
Have you already tried it?

 

[JDXakaSNK]

Well you issues are not bad comparing to mine. Seems like my lateral button of the extreme saving mode is still ON! Never dropped the mobile, neither dropped in water or hit some hard surface. Looks like i can't go off that saving mode, even moving the button.

So, is like 4 days that i have a nice mobile with calls and text available, plus calculator and the basic features but no way to switch back to my apps :s

I asked the assistence cuz i still have the warranty and they'll let me know what to do, if they can fix it or i have to ship it back, ah i did already the wiping date of the mobile with a reset.

Stay tuned for more!

I bought my second P2 today. It has the same sound interference issue as my first one

To reiterate, when listening on headphones and the volume is low (like listening to chillout or classical, meditation etc.) there is electrical type interference sound. I have been experimenting and have isolated to problem to WiFi. If I turn WiFi off on the phone it stops altogether. Also, I think that the more data that's transferring, the more interference.

It is there whatever is playing - music, Netflix etc. Even when notifications play it can be heard. Obviously if the volume is turned up it is far less/not noticeable but it is always there.

I have managed to capture a recording of the issue:

https://youtu.be/r0z6X7zB-pw

This was at low volume as it illustrates the problem best but it's clearly heard in the recording.
I captured this audio by using a 3.5mm audio cable to output the audio from my Lenovo P2 to the AUX-in on a speaker system. I then placed another phone next the speaker to record the audio using an audio recorder app. The uniform static background hiss is produced by the app.

I LOVE everything else about this phone but as someone that uses my phone for music for many hours a day I cannot ignore these sounds.
I find it hard to believe that I can be unlucky enough to get two faulty P2's so there must be many more with this issue if not all and no-one else has noticed the issue yet.

I have tried 4 different sets of headphones and the issue is the same.
