[Q] Touchscreen problem

Hi everyone,
TL;DR: I have an issue with the touchscreen of my Find 7 qhd (x9076), while on any other ROM than stock it my touchscreen glitches or something.
After installing a custom Rom, like PA, Dirty unicorns, CM, Nameless or any other available for this device (I believe I've tried all of them). The device works just like it should, nothing wrong with the touchscreen. But after like half a day, it starts to 'glitch'. Sensitivity is very low, when I press here it detects a press somewhere else.
I've got a temporary solution which is wiping the cache in recovery, then it works for a short period of time, but then it starts gliching again..
On stock rom the issue doesn't exists, but I realy do want to use a custom one.
Is anyone experiencing the same issue? Or maybe someone who has a solution?
Thanks in advance!
P.s every install is a full wipe, tried multiple recoveries, non-unified

I've read that the touchscreen fixes implemented by Oppo only work on ColorOS even though ROM makers have already implemented the fixes into the Roms. I'm not sure why, though

Hmm that's unfortunate, but it seems to me that I am one of a few people having trouble with this? Why don't other x9076 users have this problem?

Try to flash back stock recovery then flash COS 1.20 in systembase, then upgrade to COS 1.25, Then upgrade to 2.0 or above. Then flash custom recovery and rom again. This is the step you will not have problem in custom Rom. I am 100% sure.

I have the same problem, and I'm running Stock OS.
v2.1.4i Beta
This is how I bought the phone, interesting that it reads Beta...

I've updated to the latest firmware and still having touch screen sensitivity issues.
Someone has got too have some advise.... Oppoooooo.....

TouchScreen Auto Test - FAIL
I did the TouchScreen Auto Test and showed FAIL. Has anyone else shown this error?

Hi, I am having exactly same touch screen problem with custom roms, have tried both Omni and crDroid.
Is there a solution for this? I didn't have this problem in COS before.

What's the auto test?
I‘m on COS 2.1.5I and sensitivity works ok so far. I did have auto brightness problems but xposed and gravitybox has helped me adjust a lot of that out. Now it doesn‘t over dim in low light.

Auto test in COS is ok, I only had this problem in custom Roms, COS worked smoothly,so I reckon it's could be driver issue in custom Rom, maybe there are new fix for some panels are not included in custom Rom.

I never had any problems with touchscreen on find 7 until now. I have been extremely satisfied with this device until now. I have the find 7 9076.
There is a lengthy discussion of this touchscreen problem on the oppo forums.
My opinion is, it has nothing to do with the rom or firmware. It is a physical problem caused by heat. Once overheated, the digitizer gets somehow damaged.
I left my phone on a table in direct sunlight for hours while working on my lawnmower. I noticed it got very hot to touch. Ever since then my touchscreen has problems where there were no problems for 2 years prior. Dead spots, phantom touches and behaves sluggish in certain spots. Upper screen in portrait.
I tried wiping and reinstalling. Nothing works to fix this.
I even tried sealing it in a ziplock bag and freezing it. This actually works but its only temporary. The digitizer got damaged from heat. There is no "software" fix.
The only solution I can see is to physically replace the digitizer. This is a difficult thing to do but can be done.
I am considering replacing replacing the entire screen along with the digitizer as this is much easier but the problem is getting the high res replacement. Most after market screens are not equal to oppo's. The cost of OEM is too high.
Shame because this problem makes me now shy away from oppo devices.

Okay,
I opened up the phone.
Set to try and pry off/seperate the digitizer and replace with new one.
Decided to try something first.
Unplugged the digitizer and held power button (to release any stored up energy in the phone). Resnapped in digitizer cable to connector.
Reassembled the phone.
Put battery back in. Rebooted.
Sure enough, its all working. The full touchscreen is working with no dead spots or glitches.
For how long? Who knows?
Keeping this thing out of the heat.

Anybody lag on keyboard

Hi everybody,
I've got a 16Gig nexus 5x which I recently purchased, and everything works fine but I have a very silly problem, but definitely critical to me.
I just have a problem with the backspace button of the keyboard which sometimes it seems very laggy. I mean when I write something and want to clean it with the backspace button and push it bunch of times it works with lag.
I tested all other buttons on keyboard and also tested a bunch of other keyboards but the problem is still existing.
Can anybody please help me with this issue? It can be a harware problem? I mean tauch problem?
I will really appreciate if anyone just gives me a hand with this....

I've the same problem as you. My keyboard would lag sometimes especially on the far right side of the screen. It would lag for a sec or two and goes back to normal.
Anyone else having the same problem??

Thank you buddy,
So you think It is software or hardware problem?

I've just checked my keyboard in both portrait and landscape and all the buttons respond very well. Maybe it's the rom your on? If your on stock I would say it might be your phone. Another thing I found after running a quick google search is that it seems most people complain about this while the phone is charging. If so then your not the only one but I've never noticed this myself.

No problems here.
Try clearing keyboard cache and data.

I'm also having the same problem. I'm on stock. Tried clearing keyboard cache. Replaced the keyboard with third party one. Still no progress.

I'm having the same issue with the back button while clearing text, it's intermittent, doesn't happen all the time. I'm on PureNexus ROM.

I've tried different ROMs and different third party keyboards and still I have the issue. Now I have pure stock ROM... It's so annoying to me. I really want to look for reason and solution..

Same thing here. Its most noticeable when using backspace.

Go into developer mode and force GPU rendering. That should solve your problem.

I did, but still have the issue... Nothing happened...the same lag is still on going...

I had occasional typing lag - MHC19J seems to have fixed it/improved it a lot though.

That's a good news, would you please guide a bit much more? Who is MHC19J? How can fix myself too?
I really appreciate

Thank you buddy,
Would you please tell us about the process? How can we fix it?
Thanks a million for it :good:

MHC19J is the latest stock android build for the nexus 5X. After the March security update (build number MMB29V) a further update was released incorporating a few other changes with the build number MHC19J.
The MHC19J build has been widely reported to help with the 5X in several areas such as performance and memory usage for a lot of (but not all) people.
You can either wait for your phone to receive the update which is rolling out slowly, or flash it manually by downloading the factory image from https://developers.google.com/android/nexus/images - I chose to download and flash the whole image which wipes all your data etc but does give you a nice fresh install. Just make sure you back everything up first.

Thanks buddy,
But I checked I am on the same build MHC19j. But I got it through OTA. I give it a try with fresh image install and I hope the problem would fix on it.

Sorry to hear the update hasn't helped you. It vastly improved (but did not eliminate) by keyboard falling behind while I was typing then suddenly catching up on the missed words I had typed.

I'm on MHC19J and I still have that Keyboard lag. Especially when pressing 'Backspace'. Tried many Customs roms. Custom kernels. Hasn't solved my problem yet.
I upgraded from a G2 to N5X. And i'm regretting the decision i made. Not only G2 didn't had any problems with touchscreen. It didn't even had touchscreen lag like on N5X. Whenever i'm typing it feels like keyboard is catching up to me after few milisecs which is frustrating to say the least.

How is it possible that some people have this problem the others not?

Random reboots OOS 4.0.x

Hi,
I'm experiencing random reboots since I've upgraded to OOS 4.0.x (I've had them since 4.0.0, but I've got them too on 4.0.1). My friend has the same issue. I think its weird that I find very little about this issue. I think it happens the most when switching from LTE/4G/Mobile to WiFi and vice-versa. I can not say that the reboots only occur when switching.
OnePlus support suggested me to do a clean flash of the rom. (Isn't that the same as a factory reset? I did not have tampered with my phone.. Everything is stock. (ROM / Kernel..) Even the device is not rooted and the bootloader is still locked..
Are there other people who have this issue?

I have been experiencing the same situation with you. Sometimes during charging, sometimes just randomly.
Your suspect with network/wifi switch could be right as my network quality is quite bad and it jumps around quite frantically. I did clean flash but still issue persists

Working fine on my end but I'm using the Chinese A3000. Might be only affecting A3003 and US A3000.

Nope, I got a Chinese one too and i have really got issues with that random reboots, because my alarms dont work anymore after a reboot.

I'm on Open Beta 10 and have the same issue, on a clean flash. See screenshot attached. Not sure what's going on. Phone was plugged in each time but one.

Collegue of mine has the same issue, (also OnePlus3), other friend of mine has also the same rebooting issue. (OnePlus3).
It's weird that I don't find as much information on the internet regarding it..

Video Stutter Issue in P2

from the last few days i am facing frame skipping in video playback (including youtube app, mx player, vlc) , the video lags and skips few frames.
I did a factory reset, installed deodexed version, wiped cache even reinstalled stock but the problem is still there
Anyone with some info please help
thanks in advance

Yeah bro,i am also facing same problem, BTW did u find any solution?

I'm also facing same issue after nougat update,
I have factory reseted my phone, updated all apps and applied system settings (enabled 'FORCE GPU RENDERING), but it doesn't solved my problem.

Yes it's present in stock ROM nougat version. On mm there weren't any such issues.
Sent from my Lenovo P2a42 using Tapatalk

i don't thinks that its a solution
but after flashing the nougat rom through fastboot the problem of stutter has reduced greatly
now it doesn't stutter that often

Any other solutions for this problem?? i have already factory reset it 2 times and i don't want to risk my new device doing fastboot flash :crying:

any solution for this prblm

I updated my phone to 244 and did a factory reset still the problem persisted but the stutter doesn't seem to occur when I keep it in airplane mode. Can anyone try this.

Guys, I guess I figured it out. Turning off the "participate in the Lenovo experience program" in about phone in settings fixed mine. Hope it works out the same for you guys.

Doesn't work for me, had it turned off from the beginning. The problem also applies to alarm sounds for me, they pause for a split of second every 10-15 secs, is it caused by the same thing?
Is this a common problem or only happens to some of the ppl? How can I know this? I bought this phone yesterday and after it consumed 25% of battery overnight I seriously consider returning it The battery was the main reason I purchased it and now is seems not only it doesnt work properly but other stuff is broken...

Did you update the phone to 244. If not then try it and check again. There weren't any other problems for me other than the video stutters.

If the question was for me, then yes, I did update to 244 and did a full wipe afterwards.

Hmm. Guess your only option is to give it to Lenovo service center and make them roll it back to marsh mellow.

Weird Bug!!! Seems it happens only when using Jio sim in nougat. It will not lag when u switch on aeroplane mod...

Same for me, airplane mode solves the stutter issue. Can you confirm that it works OK on other sim cards.

How does this help me with YouTube? I believe that it will not even load without internet? And what is "Jio"?

It's a 4g carrier in India. Btw have you tried airplane mode. We know that you can't use YouTube but try Mx player or vlc for stutters while in airplane mode. We just want to narrow the possibilities.

I bought a Bluetooth headphone yesterday and it seems to get worse. It was then I found out that an app named Android system was draining my battery but is not the actual Android system(check the screenshot).I went to the app manager and force stopped this app and haven't felt any stutters till now.
Edit: Although the app opens up after a while even if you force stop it and the stutters continue. Need to check after freezing it.

Does this problem still exist? Planned to buy this phone today... but meh, thats a dealbreaker.
Does this problem occur on Custom ROMs too? damn ... i want this battery monster.

The phone doesn't have any major problems such as this one on marshmallow at least from what I hear but running it on nougat will make you to face such problems and Lenovo provides a crappy support.

[PROBLEM] - Fingerprint sensor not working

Hi guys, I'm currently on AEX 4.6, everything is running smoothly but all of the sudden my fingerprints sensor is not working as well as the slide options. The actual button works. It clicks so I'm managing to use the phone normally but no u-touch function. I've already tried different roms and nothing seems to work. Has anyone experienced a similar problem? I'm afraid it's a hardware problem.

I'm glad to say that I found the solution for this problem on another thread. The sensor driver might have had an issue, so installing it again will solve the malfunction. After all it wasn't a real hardware problem. Just download the file I'm sending and restart your phone so it'll come back to life again :laugh:
Here's the link:
dropbox. com/s/0gqvvfzae4exi12/sensor.zip?dl=0
PS: it didn't work at first with me. So I sort of gave up then I tried another time and it worked.
