Screens that loose responsiveness on froyo.

It has become quite clear that there is a small unlucky group of us that experience touch screen unresponsiveness at various times, mostly on froyo roms.

Clearly I realize there are other threads that have discussed this in the past. I would like to find out just how common this problem really is and what we can do to fix it.
My personal experience: My screen works almost flawlessly on any eclair rom. Every froyo rom I have flashed (almost all the super cleans, vanilla AOSP, MIUI etc) I will experience unresponsive spots on the touch screen. Typically it starts in the lower left 1/4 then spreads to the entire screen. A brief lock and unlock of the phone usually gets it working again, only to return a few moments later. When my factory Samsung charger is plugged in the screen is completely useless.
Originally I thought it was a kernel problem but it still happens on the new OE released EC10 kernel as well as on the AOSP built ones. I think it is a hardware problem on certain phones. Why only froro? I have no idea.
Please participate in my survey so we can figure out how bad this really is.

I have also have the screen responsiveness issues. The middle of the screen becomes unresponsive and I have to lock and unlock to get the screen to work. This is only an issue with froyo ROMs. My wife has a fascinate and even though I flashed her phone the same way, she never has had screen responsiveness issues.

Excellent information, same method different results. Only difference, the phones themselves.

So far, my Fascinate is running SC 2.9. 2 with absolutely no problems. Did it take a while for those symptoms to start or was it right away?

It always happened right away (sometimes within a few hours). I should point out this is not developer related. I have the same problems on fully bloated stock roms. I should have mentioned that in the op.

If you Odin back to stock DI01, does it still happen? If so, it sounds like a hardware defect. I, for one, have never seen any screen responsiveness issues at all on my phone, no matter which kernel or rom I'm on.

I am having the same issue. Mine is most often around the letters "s" and "k" and it seems intermittent. I was running DJ05 up until a few weeks ago. Then I flashed an EB01 kernel with DarkRevenge, and started to notice this problem. No issues when running DJ05.

Yes, I tried this too. Along with various cocktails of wiping and clearing cache's, no change.
*When I return to any eclair rom it works fine, again why only with froyo??

Just flashed JT's new EC10 kernel and so far no screen responsiveness issues (8+ hours), I'll keep you posted.
Update: my screen responsiveness issues have come back.

I had this problem on some versions of SC 2.8 and at first with 2.9, but now on SC 2.9.2 I haven't had it.
Mine was mostly around letters O, I, N, K, but also sometimes E, R, A, and S. It usually happened after I had already pressed the letter. Take for example this message "I ran into...." I could type the letter I to start, but when I came to it again, it wouldn't register. Same with the letter N.

I had this happen after flashing certain themes. If I ran the ROM themeless, it wouldn't happen.
Factory wiped, ROM (2.9.2) refreshed, and have been running Nitsuj's gb theme with no probs for a few days now.
2.9.2 Voodoo Fascinate

GizmoDroid's CWM fix has stopped my screen resposiveness issues. It's worth a shot. I'm currently running Superclean 2.9.2 voodoo with EB01 radio.

I also have the issue. Sometimes it will happen on the lock screen stopping me from unlocking the phone. Same fix though. Had it on all SC roms, AOSP and blackhole.

Just did the whole process twice, no change. . . It always seems to be okay at first but a little while later it rears it's ugly head. While in portrait mode if you bisect the phone vertically it is the right hand side that goes dead, the left works fine.
Back to eclair.

Ditto on mine. After a while it becomes so bad that it happens everytime after it goes to sleep by itself. I would have to reboot to keep it going ok for awhile.

Yep same thing here. Not sure when it started but it was most prominent with maybe SC2.8 I think.
It seemed to go away with SC 2.9, but it happens ever now and then.
Always the right side of the screen, simply turn the screen on/off to fix.

Download Advanced Test Card from the market. Give it a try.

Touchscreen accuracy issues (with pictures)

I recently became a big fan of the galaxy tab and purchased two for my family and talked another two of my friends into getting them. We've all noticed an issue with the touch screen AFTER updating to the overcome firmware (both 1.6 and 2.3).
I've done tests with the stock at&t firmware and then also after flashing to overcome. Seems there is something in the kernel that changes the sensitivity of the screen so that it over-registers the touch.
Let me say that I'm aware how unscientific my test is but I've done it so many times on different tabs that the results that I've seen is very consistent. You can try also to see if your tab has the same issue.
Download the app called Sketcher from the market and select the Simple brush. Draw horizontal lines starting from the top down. With the overcome kernel, the lines are extremely jagged especially on the left side. On the at&t stock rom, the lines are almost perfectly smooth.
This is noticeable through daily use too. Just hold you finger down (preferably on the left side) on the stock browser and you'll see that the screen twitches.
I wasn't sure where to post this but hopefully one of the rom developers can take a look into this.
Please see attached pictures to get an idea of what I'm talking about.
There's probably a way to adjust the sensitivity but I don't see any apps in the market that allow this.

Theres an app in the market call, touch screen sensitivity booster (something like that) only problem is, that you need to apply the "settings" every reboot.

The problem here is that the screen is too sensitive. Actually I'm not sure if it's a sensitivity issue or something else but it is definitely a widespread problem that affects most if not all tabs running certain custom roms.

No need for custom rom with stock gingerbread, in my opinion. When I was on froyo I tried the overcome kernel, videos on native player was choppy at times. I didn't have this issue with stock kernel. So now I stick with stock rom untill we have a fully working cyanogenmod.

Fried Screen on my Fascinate via Voodoo Color or Glitch

I am fairly sure that Voodoo color and the Glitch screen modifications fried my screen this weekend. This is just a warning that full brightness with modified firmware may possibly physically damage your phone.
Process for what killed mine:
Installed CM7.2 RC
Installed Glitch 13.1
Installed Voodoo Control Plus
Set color profile to the more vivid one (don't remember which)
Set auto brightness, 60 screen for dark, 190 for bright setting
Installed QuickPic
Set option for "Max brightness when viewing"
View a 2 bit color image (pure white, pure black). Noticed wavy lines in the white sections. Double checked that I was not over clocked, or undervolted, all factory settings.
Return to viewing image again at full brightness, holding up to eyes inspecting it, screen turns itself off. Never to turn on again. Phone boots, receives calls, everything is functional except no life from the screen. Odin back to stock worked fine, but screen still dead.
Posted in General because the warning scared me. *shrug* Move if needed please.

I farted that day. I think that had as much to do with your screen dying as anything you just mentioned.

[Q] Help - Can Asus tf101 dim screen before screenlock?

Hello. Haven't found this one answered yet. Can TF101 be set to dim screen before it times out and screenlocks? This would give you a warning to touch the screen before it shuts off and locks. Just updated to stock ics and can't find a setting nor 3rd party utility to do this. My Galaxy S2 does what i am wanting to accomplish. Isn't this a standard option on Android phones and pads? Thanks!

Mine does it, running Team Eos ROM. Screen dim slightly a few seconds before it shut off.

I'm stock ICS and mine dims slightly before also
Sent from my SGH-T959 using xda premium

Doesn't ALL the TF's do this?? Mine sure does.

yeah the TF does dim just before it screen locks.....unless you have the screen brightness on the lowest setting, in which case of course theres no dimming before lock.

Isn't this an Android feature? My G2X on an ICS rom dims, it's how I know I need to touch the screen to keep it on.

Nexus 7 Backlight Flicker?

Does anyone else have this problem with their nexus 7? I just got my nexus 7 today but I noticed that the backlight seems to flicker randomly
It doesn't look like much in the video but it is very noticeable and gets annoying when you're reading an ebook like i was.. Here's a video showing the problem.(It's near the end)
VIDEO LINK: h**p://db.tt/28eD0NLk (It happens around 9 second in) (change ** into tt)
For whatever reason this forum would not post a video link to show the problem.. for those who wants to know what it looks like please PM me..
But basically the screen flickers randomly ..
Is this a software problem? Should I go back and get it exchanged?

I don't see a video

Also this forum has the most ridiculousspam prevention method..5 mins between posts + no link ? WTF

Its because you are new, we get a lot of trolls
Does increasing your brightness help?

I've had a similar problem as well. It seemed to happen to me on auto-brightness when it was changing the brightness level. I can't say for sure though, just my observation.

I havn't tried it yet..do we know if it's a hardware problem or software?
I just got it today so I can still return it if it turns out to be hardware

We really dunno at this point, but we are speculating software since both HTC One X and TF300 had similar problems and were fixed with firmware updates. Also someone switched it three times and all of them had this issue. Also try to run the screen in a pitch black room and tell me if the screen flicker is there. I may have a theory but need some other people to see if their units are behaving the same way as mine.

You can still post the link when you alter it a bit, insert a few *** into it, for example.

I turned mine on as soon as I got hold of it, no flicker, managed to go through and set up things, powered off and left to charged.
Coming back to it the screen would appear to turn on and off randomly, I thought it could be an app controlling a proximity sensor (I have one on my phone and I was EXTREMELY tired!), when I took it into the light there was no change.
I found that shaking it would help it flicker on and off at all intervals but didn't fix it. In the end I just started pushing random areas on the back, just before the issue went away I pressed around the bottom left quarter of mine and haven't had an issue since!
Glad I wasn't the only one with the problem though and would love to actually find out what it was.
Hope this helps!

Try this video,
h**p://dl.dropbox.com/u/13153603/Videos/VID_20120715_100253.mp4
it is using google map and you can see the constant flickering.. It doesn't look very severe in the video but it is actually very noticeable and annoying

I have the same issue with mine. It only seems noticeable when I have the brightness set to the lowest setting and on a page that is predominately white. I don't think it's the proximity sensor though, because it happens both when I set it manually to the lowest setting and when I'm in the dark and the tablet sets the brightness all the way down itself. Hope the next update fixed this, because it's really annoying!

Seems like only a small portion of nexus 7 owners are reporting this issue .. I think I'm going to return mine ...

I first noticed this flicker in a darkened room, so yes, it is definitely something going on. I'll try disabling auto-brightness to see if that matters.

I can attest that the flicker is ever present in a pitch black room as well.

Like this?
There are a few videos on youtube, but i cant post links but if you do a search you can find it

I noticed a flickering in chrome yesterday. But only in chrome and only while the page is rendering after it fully renders no more flickering.

Everyone turn off wifi and I guarantee it will go away. It happens when using wifi which makes it hard to believe that a software update can fix it.
