[Q] CM7 eventually just starts showing black screens instead of most things. Why?

This problem only really happens after my phone has been on for days at a time. I have had this problem on the latest stable and latest nightly for CM7 (each one cleanly installed after a total wipe).
What happens is that most screens are replaced with entirely black ones. The most consistent example of this is the settings screen. The first Settings screen (which shows Display, Sound, etc) loads correctly. If I click on any of those, I just get a black screen. This will happen in other applications too, like Baconreader or Browser. Also, another connected issue is that the lockscreen won't animate once this problem starts. I can drag it down to unlock, but the rotary wheel won't move at all. If I drag to the right to load my custom app, the lockscreen won't go away and it will force my to pull the battery.
Has anyone else run into this problem? I'd just like to know I'm not alone. I'm not really expecting a bugfix, especially when I'm not even posting a Logcat.

Did you fix permissions?

I suffered this same thing today. Thankfully a full restart fixed out, but I would love to learn a real solution.

Next time it happens I will, I'm just afraid it will break Facebook/SMS integration like I've had happen before.
It's just so weird since it breaks everything. The lockscreen, the options, Pandora's station list, the browser, and it goes on and on. It's like there's some sort of display mode that gets screwed up.

What version are you using. I'm going to try to install nightly 77 today after a fresh wipe.

I was seeing the same thing. Now I'm trying to figure out why my data speeds are so painfully slow on CM7 so I can't offer a fix. Flashing back to Warm to troubleshoot 3G.

I get these issues all the time no matter what kernel or nightly I'm running. It has forced me back to sense roms lol

Same problem here. I updated stable mod from stable mod. Reinstalled. Going on 4 days, no issues so far.

I have the same exact issue. This never happens on a sense rom. I did some tweaks to my system over the past week and I haven't had to reboot since this past Saturday or Sunday. I thought I had fixed it!
Then...
My phone started doing it this morning after I turned on 4G at work, literally as I was writing this post it started doing it. I then turned off 4G.. and it instantly went away. Turning back on 4G and it isnt doing it right now. Now my phone is doing something weird with go sms pro... when I get a text and I respond via the pop up message.. once my text moves to a second line I dont see what I am typing anymore... and now it has progressed to where the pop up box isnt refreshing after I send a message (this is all happening while I am typing this post). Now the phone has become laggy and somewhat unstable... rebooted! All is well. So I went roughly 4-5 days without a reboot... where as before I had to reboot at least once a day.
Thats about the best I can get with these settings:
CM7 7.0.3.1
Savaged Zen 2.6.38.5 CFS > Using SavagedZen Governor, min 384 max 998
Displaying some animations (read somewhere that is a "fix".. or helping extend the time it takes for the Black screen of death to appear).
This is after several full wipes, several when I was running Amon RA recovery 1.8 then updated to the latest and did it two more times. After upgrading Amon and wiping I did not use any backups and started completely from scratch.
So I am not sure what else to do. Some people are getting this, some are not.

hardware problem?

hi, had my desire z about a year now, since ive had it, quite rarely ive had a problem of it seeming to have a mind of its own, for example, icons may be selected, or the home screen will slide accross by itself etc. ive always put this down to a trackpad problem.
the other day (after having a miui rom installed for about 2-3 weeks, which was fine untill now), it started acting up strangely, the above problem started happening, but more severe, also the touch screen and softkey buttons would stop working for periods of time (or stop completely untill reset), but screen rotation etc would still be working, which shows that the O/S has not frose and is still working behind the scenes (making me think its a hardware problem).
now, i think ive worked out that this seems to be triggered (mostly) when i open the keyboard. (as also, when the touchscreen stops working etc, sometimes, sliding the keyboard open and close several times, will sometimes seem to unfreeze the touchscreen etc, and will be back to normal, for a while). ive tried doing full wipe and reflashing etc, but i still have the same problems mainly when using the slide out keyboard, which again, makes me think its hardware (possibly keyboard ribbon cable?)
i really dont want to send it off as that means getting it all back to stock etc, and last time i needed the screen replaced, took 6 weeks to get it back!
if anyone could pinpoint the likely source of the problem, id rather replace the part myself..
would anyone have any ideas, as they would be very much appriciated... Thanks...

anyone at all?

I got 2 Zs meanwhile but dont have any problem with the keyboard.
But sometimes when its charging i got the same issues like you - no touch is working and the screens are sliding nearly automatically.
I think this has nothing to do with the keyboard...
Hope this had helped you a bit

thanks for the reply, unfortunately im still no closer to finding source of the problem, its intermittant, happened lots yesterday, not so much today, maybe the digitiser? its like there is another invisible finger touching the screen..

This would happen when i was on stock froyo, like it would cause the home screen to hang, but if i was ion an app it worked fine. I would use it to refresh of sorts when my phone was hung up or i need to reload my apps from sd lol. Sounds weird I know, but even with stock froyo i had problems with my keyboard but with the prerooted GB its as smooth as butter...

still going on, and getting more frequent, i dont think it is to do with the keyboard anymore. im now guessing it is the digitizer, its like someone is pressing an invisible finger on the screen, roughly in the center. it comes and goes, it happens for about 3 days, then goes away for a couple of days etc.
also there is very little info anywhere on the net that can help, including replaceing the digitizer itself
anyone ever replaced one on a disire z/g2?

Keyboard and Home screen wallpaper keep changing

OGP was getting laggy so I restored to factory stock. I was surprised though that the phone remained rooted, which I guess is good. I then installed FreeGee and went with CWM, same as it was before the restore.
Now, a few weeks later, I'm having some issues with the keyboard and the Home screen wallpaper. About once or twice a day (on most days), for some unknown reason, my keyboard will revert to the Android keyboard (AOSP) from the LG keyboard that I have it set to. When I "correct" it to the LG keyboard, sometimes the "Extended keyboard" option is checked and other times it's not (I always leave the extended keyboard checked). I also will occasionally get a notification on the pull-down that I need to select a keyboard.
The other issue is that the Home screen wallpaper also seems to change itself back to the default blueberry paper. This only happens on the home screen, and it does not affect the lock screen wallpaper. The wallpaper issue seems to happen at different times than the keyboard issue.
I've also had the phone reboot itself once or twice since the restore...both times while in its holster. Only reason I know this is that I hear the AT&T boot music playing in the background. Upon viewing the phone, it's verified that it is in fact rebooting.
Anyone else having these issues, or know the cause?

Guess nobody else is having this issue.
The spontaneous rebooting has stopped, as has the "extended keyboard" issue.
What remains is the wallpaper and default keyboard changing issues. They both change at the same time now, about once a week.
What I was able to nail down is that this happens after every time titanium backup (free version) does its weekly thing. I have no idea what setting(s) I may have enabled to cause this. Anyone have an idea they can help out with?

I have the exact same problem with my home screen wallpaper changing. Ive had my optimus since about july and the first time it did it was like 2 weeks after i got the device. Kept doing it even tho i would change it back and not do anything with it regarding the screen. Wasnt sure what to make of it but whatever. It didnt do it again until yesterday (24th) and it wouldnt stop. Had to change my screen back like 5 times, and i just woke up a little bit ago and it was different again. The phone was just laying there. Didnt touch it so i have no clue. Ive tried going thru the settings to see if maybe i had checked something or whatever and im pretty sure i didnt. Only thing i can think of is that is just a glitch with the phone. I like the phone too much so thats not enough to get me to wanna get rid of it.

Are you running Titanium Backup?
If all else fails, you can always restore to stock and reinstall your apps and other items. Then maybe you will be able to determine what is causing the issue.

SwiftKey not working well on 2014 Note 10.1

I'm experiencing a lot of problems with the SwiftKey App lately on my Note 10.1. Even though I switched most functions off, only auto-caps at start of new line is on, I get random inserted digits or even random auto-completion (which is very annoying I can tell you) . Anyone else using SwiftKey who experienced problems on the new Note 10.1?
It also can be very difficult to start a new line because it writes the 2nd, 3rd etc. letter on top of each other.
Edit: had to remove typos and random characters 3 times in the first alinea alone.

Am doing so as we speak type. Nope, still buggy (same bugs).
I must be using the iPad too often because I find I'm unable to select words and then, afterwards, apply strike.
Edit: It also inserts spaces after it erroneously inserted "[ strike][ /strike]" (without the spaces) at the start of the post, in stead of around "speak", making me have to edit "[ QUOTE=tonytownsend" afterwards... Hopefully most of this is solvable in future.

This is just a guess, but could it be the touchscreen instead of SwiftKey?
Both my first and (after I returned it) second Note (which I purchased from another seller) have very annoying touchscreen issues.
I didn't notice it at first because the problem doesn't occur that often if you use the tablet with only one or two fingers. But then I started taking notes at the university and I noticed that I couldn't use the zoom gesture directly after I had put a part of my hand on the screen. It just stopped all of a sudden or it was very jumpy and hard to control.
It became so annoying that I installed YAMTT and checked if anything was wrong with the touchscreen. And indeed, most of the time when I put my hand on the screen as if I was writing or drawing, the screen started to behave strangely afterwards.
I found a method to reproduce the problem all the time. It might be worth checking:
- Start YAMTT in "Touch tester" mode
- Put your whole hand on the screen for around two seconds, then lift it
- If there are some touch indicators still shown, ignore them and just proceed
- Put five fingers on the screen and wait for a few seconds without moving them
- If the touch indicators suddenly disappear, you have the same touchscreen issues

I sure hope not. I started a whole topic on the Note 3 forum because I discovered it had a multitouch problem. Haven't been able to produce that type of multitouch issue on any of my other gear besides a Nexus 7. Will check with your method to see what it gives.

I checked the videos in your thread and the behavior is indeed very similar to what I got:
(In the video I haven't used the method described above yet, I discovered it just today)

I discovered that my fingers got remembered (stayed) on the screen if I left 5 of them on the screen. Happened only ones though. Then I tried puting my whole hand on it for a few seconds and then the multitouch algorithm went bananas. Tried with different Multi-touch app too. I think this is a software issue, from the looks of it.

SwiftKey has been giving me problems on my 2014 Note 10.1 from day 1, but they had become 10 times worse today. I just rebooted my Note and it now behaves as normal (still somewhat buggy SwiftKey, like before). I think there are some issues in the Multitouch driver which can be triggered by the "whole hand" method described above, and possibly by other means. My MT driver had already become unstable, hence I could reproduce a defect (finger touches remaining on the screen) without the "whole hand" thing.

Kizune, I included your video in a topic about this Multi-touch issue, I hope you don't mind.

Of course it's okay. Let's just hope that Samsung will fix the problem ASAP, it annoys the hell out of me.

I found the newest beta of Swiftkey to be buggy on the Note 1014 so I removed it and went back to Swype.
Too bad as I was enjoying the split keyboard mode.

I will very probably be doing the same. Thanks for getting back on topic.

I installed SwiftKey for tablets, not the phone version. Absolutely no problems typing for me on my note.

I use the same (Tablet) version. Possibly it is caused by a combination of settings. I have most (aiding) options switched off. If I find the time I will experiment.

Try "Touchpal"..it's similar to Swiftkey.. it's free and has plenty of thenes. I actually like it better

Newest SwiftKey is running perfectly for me on the Note 2014. It's so nice to be able to have a compact keyboard you can undock and move from any part of the screen to another. So convenient for applications. Highly recommended, please try it if you haven't

touchscreen issues

My Nexus 7 2013 model has some touchscreen issues. It's like the touchscreen craps out for a split second. when dragging icons from one home screen to another when i try to go to the edge of the screen to switch to the next screen it drops it on the side of that screen or the next one pushing another icon out of the way. then i have to move it again and move the other icon back only to have it happen again to the next home screen. always had this problem. also when typing it registers each letter multiple times so it looks like this: hhhhii hhhoooww aarree youuu. or something to that effect. it's really annoying. i finally gave up and went my computer to Facebook message someone. and then swipe is all messed up and it gives off the wall words and stuff because it doesn't register which words i'm trying to spell out. Often when using a news app i try to click to play a news video and it doesn't register my clicks. also on the web browser it has trouble registering my key-presses or touch for links or numbers or arrows when advancing to the next page in forums or web-pages. If that makes any since. and when trying to zoom in or out on the T mobile map is screws up almost every time and zooms completely out. anyways i hope you get the picture. has anyone else have this problem? it's quite annoying. I've been wanting to post about it for the last year but thought it was just my fingers.

My touchscreen is borked too. I can't type any sh*t, overall the UX has been f***ed up due to these non-sense touchscreen issues. Tried all possible hardware fixes available on net. Teared down tablet piece-by-piece, still no luck :/ . Bought this beauty in 2014, worked fine till mid-2016. Now it's a crap. I still can't find any worthy tablet to replace this beast. Will never buy any Mobile device from ASUS.

I know. I've reset mine a few times but that didn't help. It's working fine at the moment as I'm typing with it right now. Seems intermittent.
