[Q] Screen Glitches - Nook Color General

On Monday, i finally got my nook. However, after flashing CM 7.0.2, I have had terrible screen glitches i.e when i have my hands completely off the screen buttons will continue to get pushed. I have tried to reflash, but I am a newbie so my method of flashing might be wrong.
Thanks for the help!

if it persists after an initial reboot, you probably need to recalibrate the touch screen.
BTW, if you're having the screen bug out on you while plugged in, that's normal.
Anyway, sorry i don't have the link handy, but you can do a search for a touchscreen recalibration app. If you really can't find it after searching, PM me and i'll send you a link to a dropbox with the apk

It's a hardware issue. I had the same issue on my Nook color for a while. At first I thought it was software related due to CM7, but the issue persists even on stock and other roms. I actually exchanges my nook at best buy last night for a new one, and no longer have the issue at all.

Yeah I went back to stock and screen issues persist. Going to exchange it right now, hopefully get a working one this time. haha

I think it is a hardware issue... kinda.
Are you noticing any SD card problems too? I noticed some when my screen was glitching like this. It would show the sd card icon at the bottom (when I didn't have one inserted) saying "SD card corrupt need to reformat."
I bought mine on Sunday and it had the 1.1.0 OS on it. I was already noticing that it was difficult to "unlock" the slide bar because it wouldn't always follow my finger correctly... I think it's a bug in the 1.1.0 software that was factory installed. 1.2 seems to fix that.
For me I fixed it by replacing the 1.0.1 OS, then factory resetting it doing power+N twice (then N two more times), then upgraded to 1.2 using B&N's software.
Then, I formatted /system and /data and flashed phiremod 6.1
It's great now. Now problems at all. You'll still see the "Read forever" message at the beginning but that's ok.
Been using it for two hours without glitches... which is about 1.75 hours more than ever before! I will report back if the issues return.

Well got my new nook after exchanging it, works like a beaut.
hope i just didnt jinx myself.... hahaha
Thanks for the help, appreciate it.

When I put a screen protector on mine it fixed that issue.

[Q] Motorola Droid 3 Green Screen Issue

I have been noticing a weird thing with my Droid 3. I love the phone. I haven't had any issues. I do get this annoying green screen effect during transitions. It only seems to happen if I have Netflix or Youtube running in the background. I can fix the problem by going into my settings and turning off my screen animations. I am in the process of getting it exchanged. I will let you know if it is just a fluke or maybe a possible issue with the phone software.
Is this happening to anyone out there with a Droid 3?
video coming soon. Still uploading
I have the same problem between screen changes
Sent from my DROID3 using XDA App
My wifes did that too, but she was using just texts. I turned off animations and to save battery, and noticed it hadn't come back yet. Thought maybe I was only one
Edit: she says it still does it...hmmm dunno...hope it gets fixed in next update
Sent from my DROID3 using XDA Premium App
tried to replicate the problem on mine, but didn't have any issues. Hmm.
Green is usually an overlay color when drawing from a framebuffer. This just means something is forcing screen output before the frame is fully drawn. It's an out-of-sync drawing issue somewhere in the software or driver and isn't a hardware problem. I wouldn't worry too much about it unless it happens so often that it annoys you. It's not hurting anything.
I've seen this as well with youtube...I've also seen it show a partial view of my homescreen while transitioning between menus....not a big deal, but hopefully it'll get fixed soon

Happened to my wifes and my phone today. Kept going to green screen when trying to open the camara app. Had to reboot to make it go away. Im also on my third droid 3 phone. First one scratched the paint finish next to the keyboard when sliding open. The second droid 3 the speaker sounded like it was shorting out when calling or talking to someone.

Have you tried rebooting the phone, instead of getting it replaced? A reboot can work wonders.

wife's phone did this while in camera mode. looked lik she was peering into the matrix. rebuffer or not, it's an obvious software glitch. i factory reset her phone so that vzw would log the activation.

Yeah, a stuck app that is unable to redraw will do the same thing but instead of a flash it's a permanent green-screen until the app is force closed or the phone is rebooted. I've had the camera do this to me a few times and Motorola has already come forward saying the camera app has problems, including this one, that they're working on.
i could live with an occasional software glitch if everythign wasn't so dammed slow. i've yet to see this phone actually perform a function faster than my D2. the software overhead is unbelievable.

Well we could be in luck, it looks like root on the D3 could very likely happen sometime this week. 2.3.4 has been successfully rooted with the phone already on 2.3.4 and the bootloader still locked. We have P3 all over it now, too.

Screen black; battery pull required

This morning when I woke up I checked the calendar on my Captivate and everything looked fine. I had an IM app (Go) running but stopped it. I went back about 15 minutes later to look at something else on my phone and it would not wake up. Nothing I did would make the screen come on. I eventually just pulled the battery and it started working fine. This is the 3rd or 4th time that's happened and usually at night while charging.
Any ideas?
Thanks for any help
Its called sleep death. What ROM, kernel,oc/UV values are you using?
I've never heard of that, but I would definitely say that describes it perfectly.
I'm actually running stock Froyo. All of this pain lately makes me want to load up a custom ROM this weekend (assuming it would help). I just don't want to end up bricked.
Thanks
That's not sleep death, at least what I experienced, I have seen that on my own captivate. Usually mine will lock up and become non-responsive, eventually the phone will restart. I don't know if it is a common issue but one I have had often.
Ya I've had that happen. Either I gotta pull the battery or my phone poops on itself and reboots. Oh well

Does anyone know if a custom ROM would fix the issue or is this hardware related?
I've given custom ROMs much thought. Not sure which one I'd choose, etc. Seems like there is so much to read and a lot of the information builds on itself. My luck I'd try AIO or something and get down to page 80 of all the postings and realize it doesn't work for me after I already flash it.
Thanks
I started having the same problem a couple days ago. I've my captivate for almost one year already. I had stock eclair, froyo, several roms. Now I'm using stock GB 2.3.5 KI2. The only thing that I can think it changed is the fact that I added an external 16gb sd. I'll do a factory reset and remove sd to see if it happens again.

I have had the least issues on cognition 4.5.3, the gingerbread leaks for whatever reason never worked well for me. I have a S II now with no issues, but still use the captivate like an iPod touch. Working very well on cognition as I type.

I found the source of my battery leak/black screen. It was "Smooth Calendar Widget" app.

Why is the NC touchscreen so terrible on the edges?

Seems like any rom I use (currently on cm7.2 rc1 mirage) and every one of them are terrible when I have to touch something on the edge. Like dolphin HD browser. It always takes 4 or more tries to hit the refresh button. Using speedial or desktop toggle from the slide out addons pane is just as bad.

Did you try running Nook Screen Recalibrate?
Wasn't aware that existed. I can't say I notice any difference. The refresh button in dolphin is like roulette. Was the program supposed to do anything besides flash a blank screen for a bit then reset? I thought it was gonna be a touch here and there to calibrate thing.

What you saw was it. No "touch here" buttons. It helps but sensitivity at the edges will still likely be not quite as good as elsewhere on the screen. Better but not perfect.
The Nook Color's digitizer hardware and/or firmware is simply not as good as what's on other phones and tablets

That's it. It's pretty simple. You might also try a higher dpi setting. I found the NOOK app frustrating on CM using defaults -- I couldn't click the settings button -- but with a higher dpi (I like 220), it works fine. Everything's bigger, which I prefer anyhow.
There are a lot of programs to set dpi, but I use "LCD Resolution".
Myself and many other NC owners have found that using a screen protector helps with the sensitivity of the screen. I won't say it's perfect but it is a lot better than without one.

The irony is that the single worst example for this problem is the Android Nook app. It almost guarantees to drive you to the Amazon book store. I suspect B&N think they are "punishing" us for rooting, but it's only they who suffer. You listening B&N? Fix the top right buttons on your app under CM7 please. I want to use your store but it is just too painful.

Cracked digitizer causing Force-close issues

'Yello, everyone. I'm having quite a perplexing issue with my phone. I've got Younggunn's AOKP installed, and have had it for about a week (awesome work, btw) Anyway, either yesterday or the day before (too blinded by anger to give a crap), I was chasing my friend's mom's dog around the neighborhood because it had escaped. Damn mutt. My phone popped out of my pocket, landed on the street, and the digitizer/glass screen got cracked (my LCD is fine, and all touch commands work). However, since the digitizer got cracked, my apps seem to want to FC on me. Every app I've opened/installed since the screen crack has FCed 3 or 4 times, then act normally afterwards. But when I reboot, same thing. All my apps FC a few times, then work normally. I wouldn't think that a cracked screen would have ANYTHING to do with FC issues, but this is the first time I've ever experienced a cracked screen. I've tried fixing permissions, wiping cache/dalvik, factory reset, and full (clean, not dirty ) ROM install. So, I turn to you awesome guys for help, because I'm just so freaking puzzled.
TL;DR - Chasing a dog, phone fell out of pocket onto street. Cracked screen, and since then all apps FC 3 or 4 times before acting normally. Rebooting causes same thing. I've wiped both caches, done a factory reset, and a clean ROM install. Along with fixing permissions. I was NOT having this problem before the screen broke.
Thanks for the help guys!
PS: I looked for threads on this issue. I found many about FC problems, many about cracked screens, but none about the latter causing the former.
The newer builds have been having force close issues. I highly doubt it has anything to do with the screen.

That's what I thought at first. But I've been running Younggunn's AOKP build for a solid week now, and I haven't had a single FC until after the break. So a good 5-6 days with no issues. The first FC I got was about 5 or so minutes after the break.

Problem with my TF701T after rooting

I just rooted my tablet using instructions from several sources here, and have a bit of a problem. I rooted it because of a slightly annoying problem with the touch screen. It worked great 90% of the time, but occasionally I would have to tap an icon a few times for the screen to respond. I have not installed any Rom on it as I decided to keep it stock for the time being. That could change real quick though!! After I rooted it, the problem has increased. I did install several tweaking apps on it (Enterprise ram and digitizer booster, Optimus Root Memory Optimizer, and Entrophy Fixer) and a few games that I had on it before. Removing the digitizer app did no good. The odd thing about it is, I do not notice the touch screen issue if I am playing a game, only when I touch the application icons or links. There does not appear to be any app available to calibrate the screen. Has anybody else had this issue with the 701? Thanks for any help you can provide!!

I may end up trying CM12. I am also getting an error at boot up , "the process com.google.process.gapps has stopped" . It does not seem to be causing any problems, but it is annoying nevertheless. Also, this rom is nice, but I see no performance difference between it and stock. I tried that calibration app you linked to, but it does not seem to have done anything. Thanks!

I doubt it, but doesn't hurt to try. CM12 is in beta though. CROMi-X 7.1 was just released. The "xxx process has stopped" is a bug that will be ironed out soon. You did clean install the rom, did you?
But if you have the same problem on different roms it's unlikely that your touch problem is software related.
To rule out a software problem you should format data and reflash the rom. Format, not just wipe. Which will delete all data on your tablet.
Also try with the microSD out. Bad cards can cause all kinds of weird problems.

Thank you for your response. I was able to fix the process error, but I still ended up putting CM12 on it anyhow! It took me all of 10 minutes and I have had no problems so far. It is very smooth and fast. I did a wipe/format, and a dalvik wipe before I put CM12 on it using CM 6.0.5.1 (I think that is the correct version). Not sure I did that correctly though, since my download folder on the tablet was still intact afterwards. My LCD problem is more than likely hardware, but it is more of an annoyance than anything. It only affects opening up apps. The screen works great in games and just typing.
