[Q] Problems with touchscreen ?

Hi there,
someone has problems that the touchscreen is not responding?
Have CM11 - current nightly, Fournace kernel 1.0.2 and OPO lockscreen flashed ....,Only the lower right corner is responsive to inputs.
I had the problems also 2 times with the CM11S-ROM.
Has anyone else this problem?

I have the same problem. It's intermittent and goes away after a while but it comes back often enough to make my device unusable when needed. I literally can't answer calls or log into my device because of this. Is no one else having this problem? The issue persists into recovery so it might be hardware.

Franco r13 has new touch drivers implemented. Try it.
OP you say it as if your screen is never responsive, only in the bottom of the screen. That sounds like a RMA.

I will look into Franco r13 tonight. In the meantime, here is how my problem happens:
- Most of the time touch screen is working as expected
- Sometimes the touch screen becomes unresponsive to many areas on the screen, but some small areas still work
- When the above issue occurs, it is only temporary. If I let the phone sit for a few minutes it usually comes back.
- Restarting does not fix the problem, and the problem persists into recovery mode (I forget which recovery I have, but it has touch screen input)
- The problem started with phone being 100% stock, although only after the OTA update a few days ago

Yeah, try Franco then. Mine feels better now. It wasn't too responsive before either.

[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?

Perhaps this might help?

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.

Touchscreen issue (bad grounding)

When I put the device on to any insulating surface such as pillow/bed/couch/table I cannot normally operate it. Touch is being interrupted very frequently. This means in practice that I unintentionally press links while sliding through web pages, it is impossible to organize icons (since icon is dropped quickly), pinch-zoom is difficult, unlocking the device is hard, when text-typing it often doubles the letters etc.
Problems goes away as soon as I plug the charger, or take the device in my hand. This looks to me like a grounding issue, which was annoyingly present in some of OnePlus One and Nexus 7 devices in the past. Desperate users were hoping for a software update to solve the issue but it never came out.
Is anyone else experiencing similar problems with Mi 4c? I also tried flashing different MIUI versions, nothing helped.
Here is a video demonstrating the issue (you can enter hardware test menu by calling *#*#64663#*#* and try it by yourself):

I tested, mine is ok

I never really use my phone that way but out of curiosity, I tested it. Can confirm, issue is there. Touch screen goes crazy when scrolling facebook posts, chrome browser, possibly anywhere until I lift the phone up.
Just noticed that I needed to tap and scroll up/down harder than I used to otherwise I would miss it and the scroll would stop halfway through and will tap on whatever it is on the screen when it stopped.
Basically when I don't tap hard enough when doing the scrolling gesture, that's the time that the touchscreen goes crazy

works proper at my mi4c

I had the exact same problem. It is a defective screen. The problem started appear for me after 3 days of use, so I returned it to the store for an immediate exchange. I am not sure if you are in China or not, but if you are, you can just walk into the store and get a new one on the spot.

for me works perfect

Works ok on mine

Works fine here...

I can't even get the touch test started, running cm12.1, dailing *#*#*2664#*#*does nothing, as well as no other I've tried tested

Try it with some app. For a single-touch this one is just fine: play.google.com/store/apps/details?id=com.tsaysoft.touchtest
It draws a continous line and if you lift a finger (or if you have faulty screen) the line disappears.
To test a multitouch function you can play with: play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester

Thank you, I'll try those.

Mine is working as expected as well

found solution(the grounding problem is still a thing but this makes it less of an ass)
1) root the phone or just use the developer rom from xiaomi
2)then install Pimp my Rom from google play and grand root
3)go to tweaks-> touch-screen & display-> multi touch amount
and put it on 5.

Hello,
Yes. As a proud owner of one (unfortunately defunct cause I dropped) nexus 7 2013 I can confirm that the behavior is the same... Definitely a grounding problem.
When you leave the phone on a pillow or couch without holding it,bthe screen response is erratic. When you hold it or attach charger.. No problem.
Still beautiful device (the 4c), especially for the price. Snappy.
And smiu is very good made. (not a fan of miui roms...)

This happens only on 16gb version? What about using a plastic case? Does it solve the issue?

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.
