[Q] Why does my touch screen randomly stop working?

Hi folks, running CM7 with Faux's kernel and the entire front of the phone becomes unresponsive at times, seemingly randomly. Side buttons still work, turning the screen off and then back on fixes the issues. Capacitive buttons stop responding too.
Is there any reason for this to happen? It seems to occur on every nightly I've ever used, and I believe on several kernels.

Updated with logcat taken from right after I turned the screen back on.

Old bump, but still looking for help on this matter.
I've narrowed it down to being a hardware issue. Before cutting out, the touchscreen will often make seemingly random presses (hitting random keys onscreen, for example) for a second, and then crap out.
Applying higher than comfortable force to the top third of the screen restores touch temporarily, but hitting the power button on and off is the only way to reliably fix it (if only for a minute or 2). I'm ready to shell out $40 for a new digitizer, but can anyone else suggest what might be up or alternate methods of fixing it?

If it's still under warranty then try to get a warranty replacement.

Alas, I'm using a T-Mobile USA phone in Canada, so no warranty for me.

What are your frequency settings via setcpu? Maybe your min to max is too high of a jump causing instability.

816 - 216 on Faux's kernel. Happens on stock and UV.
I still think it's the touch module itself since physically squeezing the phone gets a response.

Bring it up to 389(or 4-whatever, whatever's next) and see how that works.
Or try another kernel?
Although I'm sure these were things you've tried. I give basic possible solutions.

You need a new digitizer. Mine would do something similar. After replacing it, everything worked fine.

[Q] Can't wake phone up

Hi everyone,
I am running into an issue where after making a call, if the call ends with the screen still off (either because of proximity sensor or in pocket cause of bluetooth), I can't seem to turn it back on again. I tried searching (both internal search and google search of xda) and I can't seem to find anything. Any thoughts?

Are you running an overclocked kernel or custom rom? Sounds like you are experiencing the dreaded SoD...sleep of death. Just hold the power button down and reboot your phone. It's intermittent and happens once in a while. I would say flash a stock kernel and see if it fixes it. Some people don't get the SoD often and some do.

Interesting. I just got the phone two days ago and have seen little on SOD. I've been reading the forum going back a ways, but never saw what it actually was. Thanks for the heads up and the possible fix. As a side note, I am running Da_g's .42 beta kernel on skyrocketeer.

Xoom doesnt wake up

Hey guys so my xoom has been good for over year but suddenly within the last 6 months something funny has been happening. Sometimes when i press the power button at the back the xoom refuses to wake up. And i can keep pressing all i like but it just wont wake up. At times i wait for about 10 minutes and it will work again, but other times i have to soft restart it. Does anyone have any idea what might be going on?

Mine started doing the same thing at about 6 months as well.
It would restart with a reboot with the power button and vol up, but not with just a press of the power button alone.
Luckily it was still under warranty and the repairer replaced the motherboard.
It has been fine for several months now.
Hope yours is still under warranty as well.

Noticing the same on EOS Stable. Very rare, but happened once or twice. May be worth flashing another ROM and seeing if the issue persists.
Regards.

Don't get it on the nightly builds. They are generally very stable, but lately it has a few issues with lag and audio.

I'm using CNA ROM and happened one time or two only... But it was because I was performing many operations at the same time, so it was really slow. If happens too constantly I'd go to Settings>Developer Options>Don't keep activities (check that) and Background process limit changed to "At most 1 process" or "At most 2 processes", you'll loose some of the Multi-tasking but it will be better...
All the best,

I'm just not seeing this - my latest mods have made it faster than ever for me, and by extension, should be for everyone else, too ...

When it has happened to me, there has generally been something intensive happening in the background, so the theory posted above may ring true. It may also be worth upping your min processor speed to 312Mhz or experimenting with different governors and seeing if that helps.
Regards.

Maybe so, but I was strictly speaking about those nightlies where everyone was having issues. I guess it was fixed before I even realised. lol

Just to report, switching to CM from EOS cured my sleep/wake issues. Issue most likely resides with the EOS kernel. Obviously all hardware is different, so this doesn't affect all users.
Regards.

[Q] Cyanogenmod wifi

I just want to first thank everyone who worked on getting cyanogenmod to work on the jellybean boot loader. There is a problem that i am seeing though through the threads that wifi seems to not turn on. Unfortunately i have the same problem, i have had it for both the modified version on the 30th and still have it on the official version out the 31st. Has anyone else had this problem or even any vague idea as to the problem causing?

Wish I was posting with help I just wanted to cosign that I've also been going through the same thing from yesterday's unofficial to today's rom with turning the wifi on and having the tablet freeze. Hoping it can be worked out looking forward to using cm10 as soon as possible

I can confirm that i am still having the same wifi issues with the 11-01 official version.

I also had wifi issues initially, disable the wifi sleep policy and reboot, it would work afterwards.

for what it's worth I tried this but after the reboot I still ended up with the same problem, I think I'll just stick with cleanrom for now it's been running more than well enough

I updated to 11-2 and still no fix but I think I have come across something. I don't know if it just me but for some reason the wifi region in advanced is set to Europe. I try to switch it to US but never seems to save it. Am I the only one?

I don't have the issue. I have done this twice for each rom stock, cleanrom, jb hydro and I have wifi and gps. I'm using Twrp.
wipe cache, Dalvik, Factory Reset, System ( you must flash a rom now ) so be absolutely sure you have one available.
flash cm10
reboot
boot recovery
flash gapps
reboot
This didn't fail in a total of six tries. GPS is slow and not many sats but it does work.
Once I was stuck on bootanimation. I forced power down by holding power till screen went black. Power up and booted properly.
I miss spoke on the above when I listed gps - checking my notes and reflashing, gps does not work on nightly for me; it does work on the other cm10 jb for me. Sorry! Wifi does work on both.

DANG!! As of 11/3 version, I still have wifi issues. I have flashed back when there was no CM10 and have done exactly above and still cant get no reception. I still think that the region in advanced settings have something to do with it.

I'm sorry to hear that. I had hoped the problem was the difference in the way we handled wiping and flashing. I don't understand why my unit works and yours doesn't. I don't remember anything else I did that may have made a difference but I'll download 11-3 and try again.
I'll report with that status in a bit.:good:
I was on cleanrom, flashed 11-3 as above and have wifi. I wish we knew how to isolate this problem, I'll do some searching and look at some of my logs and dmesg. There must be an answer why some units work and others don't.
When you try to turn wifi on does it turn on and stay turned on or does it refuse to turn on?
I checked my region settings and they were set Europe, I changed to US just for fun but no difference in use. I have read in the US they are restricted to channels 1 - 11 instead of 1 - 14, maybe that is one of the reasons for that option.

I was on cleanrom 2.5 before also. Had no problems with it but wanted to see if CM10 was any better. What happens is that after i flash CM10, when you first start a tablet from scratch, it will search for wifi and say in the middle of the screen "Turning wifi on" and will stay that way. So i eventually have to skip it to go on to the Home screen. When I go back later in settings to wifi, says the same thing and sometimes crashes. When I go back to clean rom or original stock, have no problems.

I can't emulate that on my unit. Have you tried the cm10 by timmytim? If you need cm10 it may be an option. It is built on the cm10 you are trying to use but with some modifications.
I'm also waiting on the nightlies, in my case I'm waiting on gps.:good:

One last shot, it will only take 5 minutes and is easy.
Power off
Remove external sdcard
Remove from dock
Power on

I now updated from twrp 2.2.2 to 2.3.1 and tried BOTH 11/5 AND timmytim versions and still no luck. Do you think i need to try clockworkmod? I don't think that would make a difference.

No, I'm afraid not.
The last thing I can think of that could be different between our situations is your wifi.
I must begin by telling you my wifi router is an antique so I don't have some of the newer features.
This is a fishing trip. Take the little info I provide and try to use it to investigate your situation.
My router provides a table where I can list mac addresses of units I have programmed and only these are allowed access, even if they have the correct password, etc.
Some of the newer units have a button that automatically looks for units and self programs the router security features and any change made since the button was last pressed. If you have such then try to sync your unit again with cm10, otherwise look carefully through your router security options and see if anything stands out that may be different than with stock rom.
I know mac addresses and such are factory programmed but they can be spoofed and on units other than asus do sometimes change with rom.
For instance if I go to google play my TF300 shows as two different unit names.
Asus ASUS Transformer Pad TF300T
Asus Transformer Pad TF300T
That is enough difference to possibly cause your router to deny access.
None of this may apply but it is worth a try.
Good Luck!

wifi issues too
I am having same problem. tried 11-06 nightly and wifi will not even turn on. Tried other nightlies, same deal. Can't understand why not happening to all units. If anyone figures it out, let us know. I really want to try CM10! I think this is being discussed on the developers forum on the CM10 for JB thread as well.

11/06 and 11/07 are both broken for me as well. I saw a post by untermensch ( I think ) in the nightly thread where he was pushing some of his work for use in cm10. Maybe in a day or two everyone will have wifi.
I have read you can flash his kernel after setting up cm10 and get wifi. I have not tried that and if a fix comes soon I probably won't.
What I have done is flash his TF300T kernel over CleanRom and it is faster and smoother. I am not over clocking, using balanced mode.
Sorry I don't have any other thoughts at this time.
Good Luck to us all!

I tried the last couple nightlies and still no wifi capability. Tried a rom based on CM10, still a no go. SO, using cleanROM for now, it seems to work very well for me. I wonder why CM10 works for some and not others? Is there a difference in the hardware from unit to unit?

Wifi works again on nightlies 11/09
I still don't have gps.

LUCKY!!!! I read the post and now on 11/9 and still the same problem. I do want to ask a question though to all that do have the problem. Were you on cleanrom before trying CM10? Does this have anything to do with cleankernel?

I know you asked for those that didn't work but.
Just for more info and being fair to cleanrom.

[Q] my phone dont wake up

Im using PA4.5 with franco kernel (i switched to this kernel because the standard kernel also had this problem
After a while i try to wake up the device with gestures (i always try with gestures first and then with the power button) it just dont turn on the display.
Adb and the home, back and option buttons are lighted up, the cpu is also pushed to different freqs, but the screen keeps empty. I need to force a restart and it boots normally.
I have turned on any gesture.
I couldnt find any to Opo related thread
Edit:
I have installed xposed app settings

Does it happen on other ROMs our only on PA?
Transmitted via Bacon

I didnt test, but isnt there anybody who has the same problem? I love this phone, and PA makes it more awesomer

Rather than waiting to see if someone has the same problem, you can do two things.
1) Search the PA thread to see if the same problem has been reported there.
2) Flash another ROM temporarily to see if the problem sill occurs. This will tell you if it's isolated to PA or not.
Transmitted via Bacon

So the phone does not turn on when your double tapping the screen or using power button?
It seems like you're having the sleep of death problem. Are you under volting by any chance?
Also, do you have capacitive buttons on? If so, do they light up when you double tap or press power?

Sleep of death is pretty much what you said. If you have your capacitive buttons on, there are cases where those buttons light up and the screen does not turn on.
Sleep of death is when your phone is still on but when you turn the screen on it doesn't turn on. I personally didn't have the problem but use the stock kernel for a half a hour. See if it still occurs, it's not rom related it's kernel related.
