Hi!
I recently bought an O3D and I'm getting some multi-touch problems.
As you can see, when you tap 3 times with another finger already tapping, multi-touch goes totally wrong. This happens after unlock/lock screen sometimes, and if you tap 3 times again the problem disappears.
Video from other user.
Kernel problem? Is there any solution? This makes playing multi-touch games (Nova for example) really anoying or zooming in browser with two fingers.
So sad to see the behavior of your touch screen, cause when I do the same test on my O3D it recognize 8 fingers without any problems. Are you rooted? Did you try for example my ROM to see if it makes any difference?

Mine recognizes up to 10, but when this happens only recognizes one at time. If you tap three times the problem is gone until you tap 3 times again.
I've tried with custom roms (one of them is yours), rooted, etc.
i confirm the problem...but the games looks not to be affected by it...they works perfectly.Only with touch test i have the problem...very strange and i have your rom thiaiZ...any other experice of it?
I have the same problem...
I'm on CM7 nightly 32 (for the P925 because of the Baseband problems)
but it is a bit strange.. sometimes it works and sometimes it doesnt, i don't know why
I have similar problem.
When I play a game the touch screen with 1 finger is okay but when I play with 2 fingers it stops to recognize the both fingers.
So I have to walk and then stop and then aim and then fire which sucks.
I have the same problem. Is this problem related with hardware?
hi everyone,
i tested this too and i noticed a certain pattern. If i turn off my phone and then turn it on and then run the multitouch tester i will get the issue you described. However if i turn it off and then turn it on and then move my finger from the left of the screen to the right of the screen 3 times(on the homescreen) and then I run the multitouch tester the issue is gone and the touch screen works perfect afterwards. Its a very weird bug. can someone confirm this on their phone also. If a programmer can develop an app that imitates 3 swipes when the phone unlocks then this annoyance is fixed.
Multitouch problem-any permament solution?
Have anyone found a permament solution?The thing is annoying.Has anyone got hardware fixing solution to this problem?Maybe the flat cable (placed at power button)?I've noticed it after 5 months of use.I haven't tried it myself with any other optimus 3d device.Could anyone confirm not having a problem?Btw, I use 2.35 official, without root or any kind of mod.Please, help.

Yeah, I've noticed this problem too and your three swipe solution seems to work fine. I also realised that I don't need to be on the home screen for this to work. I swiped on the tester screen itself and multitouch resumes working.
Testing with Antutu Tester I can get 10 simultaneous touches. The hard thing is to make 10 fingers fit into the screen

Hi
Is there any calibration app that actually works ? My sensor is tilted little bit to right.
I have tried This app but it doest work (it does nothing...)
There is example what it does... note that table is perfectly flat and horizontal.

This isnt ROM problem, i have this problem on every rom.
EDIT: Its most annoying in "doodle jump" type of games, because it goes still left even my phone is standing perfectly horizontaly (hope you know what i mean)
Can someone help me how to reset "zero" position of acc meter ?
Well, i guess iam doomed. No reply in 48 hours. :/

I have the same problem. Waiting for replies.
I also noticed it. As far I know accelerometer can not be calibrated on system level. Probably another hardware problem. Maybe sensor is placed wrong on motherboard or sth.:silly:
i have tried this thread and it worked for me http://forum.xda-developers.com/xperia-l/themes-apps/sony-xperia-l-calibration-app-t2519229
Hi, i've been using the NVIDIA SHIELD K1 since january, and one thing that has always bothered me is that it doesn't recognize my fingers when i tap repeatedly, i play these rhythm games that requiere two or more fingers on screen, and losing because of the tablet not recognizing my fingers is painful, i tried rebooting and a number of stuff i thought could work, but there's no results, it even stops recognizing while i'm holding my finger (moving an app's location, for example).
This wasn't a thing in my previous one, it responded instantly with no stutters regardless of how many fingers i had on the screen, so i don't know what to do.
It's rooted with TWRP, i haven't used any ROM's as i don't feel like i requiere any, settings are always on max performance and i kill all apps that i leave and won't use so everything runs smoother, i also disconnect from internet when playing but it doesn't seem to do anything, can anybody help me with this?
Try doing a screen calibration; that worked for me.

I've tried screen calibrating, but that didn't work. Currently android 7.0 seems to make this less frequent.
Screen calibration worked here too, K1 tablet.
I accidentally found out about it yesterday btw haha
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.
