Just a couple of observations that might help others out.

Hey guys,
This forum has been wonderful for me so I thought I would pass along my own personal experience with a couple of items.
First 'the Clip' case - great - I love mine. For those that have had concerns about the main home/back/menu/search buttons not being lighted, the clip is perfect for helping to find these keys. If you insert your tablet camera up (not upside down to uncover the usb port), the right hand clip is the perfect tactile way to find menu (just above) and back (just below). A good way to navigate these buttons in darker settings.
Second - the static/hissing/white noise problem people have experienced. I know several people have indicated it is a hardware problem and to replace your tablet, that was not an option for me as it did not start until after the 30 day return period. I have found, however, that if you set your screen to NEVER sleep and instead use the power buton to put the screen to sleep, it cuts down on the occurences significantly. Additionally, if it does happen (it has happened twice in the last week), it recovers for itself. You get the noise for ONLY the existing sound that is supposed to be playing and the next sound (whether it is a feedback sound, a notification, etc), it will have corrected itself. At least that's what my experience has been.
To all the developers out there (and especially roebeet) - thanks for everything, I love this tablet due to your hard work. I am running TnT lite 4.2.5 and am very happy with it.

how do you get the screen to never sleep?

Go to settings, display, screen timeout and set to never.

I understand you in regard of this XD i've been having this sound problem, but bought mine overseas (i'm from Chile) and my brother threw the boxing into the trash, so doubt that there is a cheap way to replace mine .
Do you prefer some ROM in particular? Now i'm toying with VEGAn 7, but i can't play more than 2 or 3 mp3 songs without getting sound off, i'll try your "fix" to see if the situation improves

hmm.. I guess VeganTAB 5.1.1 doesn't have that option.. bummer..

i had to change the tablet language to english to find that option for some reason

[Q] Issues and questions

I just received my TF about 5 days ago and I'm a little disappointed with some things. Maybe it's my fault for not doing enough research, but I thought I had. I spent about a month reading and watching reviews. Anyway, I read that honeycomb was so great at multitasking. Yet, I feel like I have a first generation IPhone when it comes to multitasking. I was using Skifta and Moboplayer to watch television from my windows media center. I thought maybe I could fire off some emails and just listen to the show in the background. As soon as I choose gmail my video stopped. I noticed that with a lot of programs. I choose one and the other stops. Is there a settings that I'm missing? Also, after play my video files using skifta and moboplayer I lose the sound after about 10 seconds. I thought it was completely gone, but when I had the bluetooth headset on last night I could hear the sound really breaking up, like the TF didn't have enough processing. Well, I really doubt that because I would suspect the video would go before the sound.
The google voice recognition on my HTC hero with Cyanogenmod nightly build 6/27/2011 (112) is just superb. On my TF I have to talk really slow and it is rare if it gets it right. I don't know if it has to relearn my voice or if the microphone isn't as good?
I purchased the keyboard for the TF. It is very slow with delays. Sometime it just flakes out. It causes my cursor to jump to different spots quite often. I thought maybe I was bumping the touch pad, so I started to peck type and it was still happening. It gets better if I shutdown the TF and restart it with the keyboard attached. Is this normal or do I have a defective keyboard? Also, It seems like I have to hit the keys extra hard to make sure it registers.
Video chat?? Where is it? I thought this was Google proud OS. I can't get Google voice, Google talk video to work? Why do we have two cameras on it?
Granted I'm new and many of these things I'll probably discover along the way or there will be fixes. I only mentioned a few, but there are other issues with this device.
Is there a better rom than the default one that someone would recommend that might resolve some of these issues?

Lenovo P2 bugs / issues

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 .

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

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?

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.

Question Is this delay real?

I recently installed a Santa Rockstar Tournament Edition, because the old one doesn't work at all, not even on my previous device. Even the new version doesn't run out of the box, needed to manually set permissions in the settings. But now that you know how to set it up on your own, here's my issue:
The audio comes to way early... yes no joke, never thought this could be an Android issue, which is plagued by to much latency. I installed the soundbrenner metronome and in the settings LEDs and click were 100% in time, no adjusting needed. The game sadly doesn't come with calibration settings, so is there an App that can delay audio system wide without root?
Edit: Just installed that on my old Axon 7 to double check, and the game audio is in sync there.
Edit 2: Looks like it was a frame rate issue... locking the game to 60FPS fixed everything.

I had the exactly same problem but change the frame rate don't do anything better

Question Weird problem of Poco X3 Pro

I had been experiencing the phone for the past 1 year and my only and haven't-yet solved problem is i am still having about 80+gb as many of a free space ROM, everytime i tried downloading more and more games, its performance drastically getting dropped. For example.. i was downloading Clash Royale, they are in total of 980Mb and at this state my file sizes are totally about 29gb, i left the game closed. After a while, i got back playing CODM, this time i sensed a noticably touch latency/delay the moment i swiped its screen at the same time i can heard a reduced game volume with also bad quality of audio. I quickly went out to delete Clash Royale as quick as possible and then everything back into normal, a hardly noticable touch latency and a louder game volume back into normal. I wonder if u guys had also experienced the same issues please let me know how deal with this

with witch one phone? if this phone was released on march this years.
LAUNCHAnnounced2021, March 22StatusAvailable. Released 2021, March 24

Ever noticed how sluggish a hdd gets once (nearly..) filled?
The less space for files, the more sluggish stuff becomes. I figured out a few years back never to use more than 75% of official capacity of disk, for smooth experience.
But low quality sounds and delays mean you may be loading the game from online as opposed to your fone?

Yeah and in my case i only used up to 29gb out of 128gb and it left my CODM unplayable game

In other words, try using less than 75% of user space, no more, test n see?
Other option, is to confirm if the fone is actually making you play ONLINE from the game SCOURCE, itself, actually on it's server, rather than the game on your hdd/ sd.
For this, I would take out sim for a moment, connect to wifi, play game. Wifi router will show the traffic if you got a good router. If it's online, bet your ass it's the downloading game files 'live' causing the lag/latency issues, not to mention the sub standard audio, standard practice for one serving games to lots of people with not much 'data allowance' -so the first thing gaming companies do is lower the bitrate of audio and visual, not usually noticed in game images, but defo noticed in sound quality...

Have u had ever read carefully my issue? I said i only used up to 28gb in total and leaving the other 80+gb memory as free, so it's more to than just 'using it lesser than 75% of total storage'

Yeah, noted, dont stay online too long, mistakes get made, I hear ya, I did read it, but got confused, I got a backpain reaching into the brain to the back of the eyes, not good, but I keep going...
Forget the space part, I did see that, so mentioned your probably playing software based on the game server as opposed to the software you installed on your fone, I've seen apps do that, if your offline, the software performs better, online, worse, try playing offline for a sec if possible?

tried reflash the rom?

You should reflash MIUI or factory reset ,If the problem persists ,you should go to an Xiaomi repair centre and get it replaced .
