[Q] Kernel or Digitizer Issue? - Verizon HTC One (M8)

I've been having serious issues with my phone lately. While typing, the gesture typing trail will randomly show up on screen. But mainly, I've been having issues with phantom touches or complete unresponsiveness. Turning the screen off and then on fixes it briefly, rebooting and letting it sit off for a bit works as well. Which is why i have the doubt is either hardware or software related.
Can someone please help with this? Anything that might help, determine if it's maybe kernel related or if it's a digitizer issue. I flahed several ROM's before it started to do that (always wiping system, data, cache and dalvik beforehand) so i don't know if something got corrupted along the way. really frustrated not being able to use my phone and type in peace.

[Q] Pixelated flashing lines on display screen

I've been having screen/display issues (not the yellow hue and separate of the touch screen sensitivity problems). Every now and again, I get flashing, pixilated horizontal lines. I don't see any dead pixels and when it's not blipping the screen seems to display flawlessly, so I'm not sure if it's a software issue or if the hardware is failing. Also it's not isolated to one particular area, it jumps around. Anyone have this problem? Any fixes? I haven't been able to find anything on it. PLEASE HELP. Below is a video of the problem.

Are you completely stock? Any custom kernel? Any rom?
Usually it's a kernel issue - tearing, but it's only present on custom kernels (never came across on the stock cm11 kernel). You might wanna try a different kernel though, if you're comfortable with that.
I have the same issue on my stock rom with stock kernel. the only thing i have changed was the developer options. i changed the screen animation time.

Was it working before those changes?

I had exact same issue during recording a video yesterday night !! I am latest mahdi and latest franco...
Funny thing is it went away once i exited the camera... what rom and kernel are u using ?
I've been having the same issue too. I don't have a solution for you, though. I haven't been able to find much about it.
Same issue here, stock all the way, only been since latest update. The update didn't flash properly, it gave an error stating it couldn't be located but i went through the files and it was there and then upgraded OK
I had the same problem. Selecting "Force GPU Rendering" in developer options cured it.
i have stock everything. i'm not rooted.
a reboot fixes the problem temporarily. shoot, all the issues i've ran into with this phone thus far (like the GPS not locking on) is fixed by a reboot. i know a reboot is good to do every now-and-again regardless, but having to do it constantly to fix issues is the sign of a failing device and is very annoying; it shouldn't be something you have to do with a brand new device.
i am facing this too randomly. Am on rooted 38R with Franco kernel. Rebooting is a temp cure but it will frustrating to keep doing it.
This happened to me after getting 38R. Fortunately it hasn't been back since a hard reboot. It would show up on Youtube & when dragging down the notifications area.
I had this today on PAC ROM. When I unlock phone and lock ring animation dots flash up made lines come across screen not sure what it was or why. Just rebooted phone. Back to normal. But trying out vanir later tonight try something abit different.
Also experiencing this here.
Stock ROM, clean 38R install.
Stock kernel.
Rooted, with a few xposed modules.
Started a day or two ago. Haven't found a way to recreate it. When it does happen, a reboot remedies it, but only temporarily.
I will attempt to screenrec it the next time.
I find it interesting that I only see mentions of this starting recently.
Same problem for me since the last update. Restarting the Phone solves the problem for some times. Maybe a driver issue?
Glad to see that it is not a hardware issue.
Same here
Same here, mahdi-2.8-bacon-20141001 ROM, enabled "Force GPU rendering" in Developer options, let's see if this comes back!
I have the same problem on latest cm nightly with stock kernel. And dev options works sometimes but it resets on reboot and my phone reboots randomly all the time. I'm starting to hate this device

I also have the same issue on Stock 38R update + franco kernel r27
It happens after the latest kernel update, before I never had this lines.
Lucky for me I don't have any reboots now but I fear that will come to pass as well.
Got the same problem with Mahdi Rom 2.8 - 20141016
Will be solved in Franco Kernel r28,he just confirmed this on his kernel thread.

same issue here. i have to reboot. its happened on stock and AK kernel. will try enabling force gpu rendering and see if it comes back

Accelerometer X-axis stuck (not always). Any calibration/reset tips?

Hello people,
I have been experiencing a weird issue lately with my OPO. It seems that for no apparent reason, my accelerometer's X-axis gets stuck in 0.000m/s² value, resulting in the inability to rotate the screen to landscape mode. And, again for no apparent reason, it starts working correctly... until the time it breaks again!
It's really crazy. Last night for example it was broken, I was browsing xda from chrome just to find a possible solution, and suddenly it started working, device just turned from portrait to landscape! When I woke up it was not working again. Sometime around the afternoon it started working again -without me doing anything-, not even handling the phone, it was flat on my desk! After 8 hours of working, it got stuck again right as I was writing this post...
Even when it's stuck however, If I try to shake the device very hard (to the point that it almost flies off my hands) I get a very small reading, around ~0,050m/s² to ~0.200m/s².
(readings were taken with Sensors app)
A reboot does not fix this. I have tried lots of configurations, it's not app/xposed related since it also happens after a full wipe and after flashing the 44S fastboot image. It's not kernel related (I think...) since it happens both with Stock and Franco. So it's either hardware, or related to the ROM.
I believe (and really hope) it's not hardware related since it started a while after flashing 44S, before that the accelerometer worked flawlessly. Also, I may be ignorant here, but if it was hardware it would break down once and for all, it wouldn't work intermittently, right? Either way, the device of course was never dropped or hit so as to damage the sensor in any way.
I've also read one report of the exact same problem on the OPO forum, but could not contact the poster, and several other reports of the accelerometer breaking down (and later being fixed) but in CM nightlies.
I have already tried to calibrate/reset through several apps but without any success. Is there anything else I can try to, erm, "un-stick" it? Maybe there's a configuration file I need to delete or something or a specific way to reset/calibrate it in CM. Or even tapping the device in a specific place? (lol I'm reaching here, but I can't think of anything else).
I have already reported the issue to Jira, if someone is experiencing the same please provide your input here.

[Q] How to fix an unbearably slow Nexus 5?

After installing Lollipop, everything became unbearably slow. I've tried flashing multiple ROMs, both Lollipop and Kitkat, but everything remains so slow: the actual boot-up process and the ROM itself. Does anybody have any ideas about what can be done about this? In fastboot I see hammerhead D820(H) 32GB; HW version rev_11; Bootloader version HHZ12d, Baseband M8974A-2.0.50.2.22. Lock state is unlocked. Any suggestions will be highly appreciated!
Wipe cache and see if that helps and disable Chrome's integration into the app switcher. Also get rid of Facebook and FB Messenger.

Instead of Lollypop try some LSD
Thanks. But it is that slow even before any of these apps are loaded (e.g. after I do a factory reset and flash a new rom). Is it possible that Lollipop did sthg to the hardware? If so, how could I find out? Just to give you an idea about how slow exactly it is: when I am typing 5 letters at normal speed, it takes until the fifth letter before the first letter actually displays on the screen. I should also note that when the screen goes off, I can no longer get it on again without a reboot...
I'm still trying to figure out what this might be. I first thought my problems were similar to those that others have described, but I now think they be different. Here are some of the issues I'm encountering:
when I boot up the phone (whether in kitkat or lollipop), the initial android (animation sequence is already incredibly slow
there are all sorts of strange things happening with my screen. When it goes to sleep in Android, I can not wake it up anymore. When it goes to sleep in recovery, and I push the power button, the screen goes (again after some time) from pitch dark to a slightly 'lit' dark, but it never displays anything, and I have to reboot again to get the info on the screen. Also, the screen is even slow in twrp - when I swipe to do a factory reset, for instance, there is also a noticeable lag.
I have tried with various ROMs (both stock and not); with ART and Dalvik, etc. but none of these changes seem to affect the slow screen issues
Does anybody have any ideas about what the problem might be? I should also add that we had the screen replaced a few months ago - could that have something to do with it?

Probably the replacement screen has been reconnected poorly. There's nothing you can do on software side, for me, it's more like a hardware problem.

Issues everywhere, hardware problem?

Hi there,
I'm experiencing massive issues with the Nexus 5 of my wife. Everything is basically broken
It started 2 days ago, the phone start rebooting without reason and heating a lot. Applications sometimes hang for a long time, or the screen stays black with only the notification bar displayed.
Wifi is never able to connect, even though the welcome screen is able to display available wifi. On the welcome screen after a fresh flash, nothing happen when I enter the WIFI password and try to connect. Only the "ignore" button is available, as if I have done nothing.
LTE connectivity seems to work, but I have removed the SIM card for further testing, so it's hard to say.
Parameters screen sometimes works, sometimes won't. Battery consumption screen never works.
The phone is never able to shutdown properly, it hangs forever on the shutdown loading circle; I always have to hard-reboot.
I changed the battery (I had a spare one ordered few days before the problem occurs just to see if it improves the battery life), with no luck.
When I opened the phone to change the battery, it is clear the heat come from the CPU.
I tried (I wiped everything each time in between):
- factory reset
- flash a stock rom from Google website (MMB29K)
- flash latest Cyanogenmod rom (ZNH0EAO2NM)
I have the same issues with any of those 3 roms. I captured some logs while running MMB29K and ZNH0EAO2NM:
Stock (MMB29K) logs: https://drive.google.com/open?id=0B-CDc3nzF3e3M28tM2xjTmJKa28
Cyanogenmod (ZNH0EAO2NM) logs: https://drive.google.com/open?id=0B-CDc3nzF3e3TVUtTmExZDBLUms
The only state where the phone is stable is when TWRP is booted, which is not so useful...
I'm thinking of a hardware issue, but is there anything else I can try? What do you think?
Thanks a lot!
Nobody?
I said the same thing in another post. The fact that flashing different ROMs with the same issues kinda point to hardware problem. I'd guess something fried on the motherboard and it's causing weird behavior. Funny thing, the other post also reported wifi not connecting issues, so I'm thinking there is something that breaks in older Nexus 5 phones that cause wifi issues along with other random reboot problems.

Touchscreen Issue. Two taps becomes a swipe.

I'm having this problem with my NEW mi note 10 phone.
I notice it when first when I'm typing on my keyboard as usual speed.
It kept doing this phantom swipe across two finger taps.
I posted some videos to illustrate my problem.
Is it a software or hardware problem? (This problem is intermittent as well so it's really hard to pinpoint it)

ttps://drive.google.com/file/d/1-6M1e33Qxz8HXckkcLb3sWVTXG6fPHzv/view?usp=sharing (Using touchscreen tester, you can clearly see the phantom swipe across the two taps)
Anyone else having this problem except for me?
When this problem comes, I can't even properly play a game.
reformat factory reset - fail
reinstall latest miui global 11.1. 2 - fail
optimise animation all off - fail
gboard - fail
xiaomi keyboard - fail
SwiftKey - fail
turn off Miui optimization - fail
restart phone - fail
clear ram, clear cache, clear recent, speed boast - fail
CPU slowing down due to background processes?
Touch digitalizer got problem? (I tried shaking it gently, poking it but it does not affect anything at all)
As I said, this problem is intermittent. There are times when I can use it without any problems at all.
It's really weird.
It can be totally fine one moment and then it acts up again.
There's another thread about this. Most of us face this issue on all variants of the phone (Pro/Lite). This started with April or May update where Mi added a edge sensitivity control setting.
What happens here is that touch sensitivity suddenly reduces and it will be hard to do anything that involves rapid touch such as typing.
Lock and unlocking the screen or restarting the phone will fix this temporarily. There's no permanent solution.
Also when this issue occurs again, go to the settings and turn on Game Turbo for an app such as WhatsApp, without and then try typing on WhatsApp, you will see that the issue is gone.
We all are waiting for Mi to fix this. But I would advice to return the phone if it's under warranty though this is a software issue
