Keyboard/Touchscreen Help - EVO 4G Q&A, Help & Troubleshooting

My evo is acting up, hasn't been activated for 30 days yet so I can't file an insurance claim on it, wondering if there is something I can do to try and make it work. My touchscreen goes through spurts where it acts funky. The V G and Y keys don't respond to any touch and the whole area around the keys seems dead. when I hit either of the keys the screen picks up the key to the left of it. Now it doesn't always do this, just sometimes. I can rub the screen on my shirt and the keys will almost always go back to working. When this happens sense also acts up. Swiping to change screens doesn't work. Sometimes the screen hangs halfway between screens and stays there. Also with the browser when I try to scroll the browser will zoom almost like there is another finger on the screen doing pinch to zoom. It seems like a software problem because also at this time all of my sense widgets get messed up.
Is there a way to re-flash the stock rom back to the evo and start over? Hard reset doesn't do anything to alleviate the problem.

Don't chance it. File a claim.

[Q] Screen wont turn on after it turns off. ATT Tilt 2

Everytime I boot my phone up, it works fine up until when the screen goes into sleep mode. Once it goes into sleep mode I cannot turn the screen back on, it stays black. The keyboard, end and answer key lights show up when I press the power button but the screen just stays black no matter what button I press.
I end up having to either take the battery out or using the stick to press the reset button on the side in order to get the phone to where I can see the screen again. I have adjusted the settings to where the screen doesnt go into sleep mode and the screen just stays on but that drains my battery. I want to be able to have my screen go off so I can save power but if it goes off it wont come on again until I reboot.
I have done a hard reset. This problem started happening to me when I started using the Energy Rom but I've even flashed different Roms and the problem still exist.
Somebody please tell me what's wrong! I need help! This is a big annoying problem to have. Thanks.
is this problem occurring when you slide the keyboard out?
i had the t-mobile touch pro2 with this problem.
the screen would die when the keyboard was out and not come back.
if this is the case, what i did was...
well. obviously not open the keyboard fully.
but if i accidentally had.
instead of pulling out the battery, i waited...
till the screen 'naturally' went to sleep.
than i would pull out the stylus or press power button
and the screen would come on.

Yes the problem still exist even when I slide the keyboard out. Once the screen goes off, that's it....pressing the power button to get it out of sleep mode, sliding the keyboard, I press all buttons and nothing works. The only thing that "works" to get the screen back on is removing the battery or using the stylus to press the reset button.
When sliding the keyboard out the keys light up but the screen doesn't come on, also pressing the power button lights up the end and answer keys without the screen coming on.

so. whenever the screen goes out, period, you cant get it back?
or the screen goes out and cant get it back once you slide the keyboard out?
if it is only when sliding out the keyboard...
try not opening the keyboard fully on the right side.
on my rhodium, after that point, the screen goes out.

Yes, period. Also, you know when you put your face to the phone during a call and the screen goes off so your face wont press anything on the screen? It doesn't come back on from that either once I end the phone call, it just stays black. I'm assuming you don't have any other suggestions. This Sucks

This has to be a software issue but I don't know where to start. I'm surprised nobody else has encountered this problem. I've grown frustrated of this issue because I don't understand why it's doing this. I have had the phone for almost 6 months only dropping it once 4 months ago and it wasn't a strong damaging drop that would affect anything inside. I guess I'll just have to go last resort and call warranty to swap the phone out. Thanks for the help.
Same problem

My phone also dos not come back on, when I put it in out the sreen with the power button on top, or when the phone goes to sleep. Nothing can put it back on(opening te keyboard, pulling out the stylis, presing the answer-, windows-, back- and end button). I and up using a music players too keep the phone busy what's makes it operational. Cant really remember when this started happening exactly. My phone is at the moment loaded with a standard ROM. I used too have a custom ROM.
My TP2 does this too, although I only encounter the problem sometimes when someone calls. I answer and put the phone next to my ear, the screen goes black as it should and the phone just dies. I can't hear what the other person is saying and the screen wont turn on anymore. I have to take out the battery to reboot.
set light sensor to manual in settings. You have some bad or fragmented code causing the problem. Pretty common actually, many different reasons, but usually either a bad light or proximity sensor or software issue. Setting the sensor to manual should do it, if not, hard reset and allow the phone to fully set up before touching it, to allow full customization process to complete. Search my posts on SOD (sleep of death) for more information.
Funny this was brought up. Now im worried I just dropped 250.00 and have a new one coming.
Mine started with the ear piece quit working. couldnt hear anything except on speaker.
Anyway I started having the screen issue over a month ago, only way to get it back was soft reset with the stylus. Also when the screen was lit, I couldn't hit the power button to turn the screen off. At times the screen would be on 24/7 and I just dealt with it. The times when it decieded to go to sleep was when I needed the soft reset. Well long story short I forgot my charger one day at work and the battery died. after pressing the power button for hours with no response, moving the screen in all diffrent directions as I pressed the button.It came on once after hrs of messing with it. Well today it died again and I am fed up with it so out came the tools. Once I opened it up I noticed the ribbon that feeds the screen from the mother board was worn and torn. the ribbon slides everytime the keyboard is slid out and it rubs on both sides of the phone. I thought maybe mine was just a fluke and was installed wrong considering the phone being 10 months old but now I read this and see maybe its a common problem. The cheapest I could find the Ribbon was 56.00 so I didnt want to chance it not being the issue.

Go Launcher help - screen shifting and contact

There appears to be NO means to contact the go launcher folks (just spent 30 minutes trying gave up)
anyway LOVE go launcher. problem is the main desktop has 5 screens you can swipe/slide whatever between.
the MIDDLE one is primary. you then have 2 left and 2 right.
for some reason I keep ENDING UP at the far right screen which is very annoying cause I then have to swipe left twice to get back to my main screen.
it seems totally random I will turn on the phone and I am on the extreme right screen.
I also notice if I press home I go home but if I press home a SECOND time it ALSO takes me to the far right screen.
anyway to change/stop this from happening?
Strange... I've been using GO launcher for some time and never had an issue like that. Bad install, maybe?
Not sure. Just installed calkins rom. installed go clean instead of from backup.
will see if it happens again. VERY annoying. SO FAR so good. in fact now home does just what it SHOULD do.
takes me to the center screen and if I hit it twice GOES to center screen if not on center screen.
hopefully it was just a hinky install.
alas like an idiot I did not backup my contacts so the 4 hours I spend attaching pictures and correct numbers and entries in my contacts. all that work POOF. what a moron.
also all my circle launcher backups I carefully made are GONE. I had assumed they were saved to SD but apparently not. what is the point of backups if they go away with the program ???
U can change ur home screen by going into preview and clicking on the home button

Don't want to change the home screen. I want to stop it from moving around
it appears it was a "bad install" or something corrupt.
I installed calkins rom today and clean installed a fresh download of go launcher ex and so far its been PERFECT.
and in fact home works as it should double tapping it takes me to the "center" home screen.
so must have just been a goofy install or a corrupt file or something.
my reply stands ur home screen was not set as the middle screen but the far right one that's why it always went to it and u had to scroll to the left

Agreed.

You know I was about to make a snarky reply of ok smart a$$ you show me the setting. I have been through the settings and there IS NO SETTING for such a function.
and I would have kind of been right. there is a flat out hidden in plain site setting for it I happened upon by accident.
a screen I have NEVER seen before. in fact first time I saw it I had no clue how I did or or how to make it do it again.
after some experimentation I found out if I "swipe up" (something I usually have assigned to a function but had no done so yet on this install) this NEW window appeared that I never saw before.
it have all 5 of my "screens" displayed in miniature and the home screen was "green" but I was not ON the home screen (only reason it stood out to me otherwise I would have ignored it)
and then it hits me. I bet whichever one is "green" is the one it defaults too. sure enough if I touch the house on one of the other "screens" IT became green.
sure enough it was the "default" now.
I have no idea how it got changed (maybe when I was reaching in my pocket or something??? because i had never seen that screen before and I can find NO means to "invoke" that screen THOUGH hold on that give me an idea.
HAHAHA sure enough if I goto "EDIT" from the soft menu it brings up the same miniature window display. I had never bothered with THAT either
Just assumed it was to EDIT the "dock bar" which I had no desire to do.
so I must have gotten into that screen at some point and changed the "default" and never even knew it
how funny. of course I canceled the aggravated post and waited till I got home (now) to reply. Just found out "edit" did it right now too
I guess I misunderstood your original post. It sounded like you had been able to get to your intended home screen with one click, but a second click was sending you elsewhere. Sorry, guess I overthought it.
thats what it was doing.
many times it was at right screen (boot up wake up etc..)
sometimes it would take to home but hitting again would goto right screen.
I am almost certain I somehow "changed" the default screen as "home" without knowing it.
when I do it on purpose now it behaves exactly the same way it seems.
at least its fixed now and if it does it again I know whats wrong

Touch screen stops working at random intervals until i refresh the screen

So... I replaced my perfectly working glass screen the other day, just to change the color
All went well it seemed.
But now, the touch stops responding completely at random intervals. Sometimes after a minute, sometimes after an hour.
All i have to do to get the touch back is lock and unlock.
I updated my rom, no go. I cleared cache and dalvik, no go.
Any ideas? :silly: thanks
I went to developer tools and enabled the option that lets me see the touches...
it seems when my phone stops doing the touches, its because there are like 8 different locations on the screen that are being "touched".
I messed something up obviously... but it seems to go away when the touches are reinitialized...
Is there an app out there that will automatically refresh the touches automatically? That would fix my issues...
I just now found out how to replicate the issue on command!
If i press down hard on the screen, it stops responding to my touch commands.
at least now i know how NOT to get stuck... just have to hold it gently
I think the reason was because i didn't put enough glue on the glass screen, thus its too close to the digitizer... and when i touch too hard the glass touches the digitizer and causes it to go all outta whack. mebbe...
i'ma put more glue on it and find out though.
thanks for all of your help so far though, you guys have been a great audience.
I did the exact same thing and have the same results. If I don't press too hard it works. Any solution would be nice

[Q] GNex touch screen

Hello,
I find out that on the right and bottom edge of the touch screen, does not work properly. some times i have to tap more than one time to make it recognize the tap. and also when i pull notification bar down sometimes i cant send it back up. it gous up for half centimeter and comes back down. (as if it were magnetized ) i have to slide it up multiple times to close it. i tried several roms, but the issue is still there.
so i am asking what is wrong with my phone? how can i calibrate my screen. what solution do you suggest?

some gnex have a touchscreen issue. a couple that i have had had bad issues with the softkeys being unresponsive. unfortunately from what i've seen, google has not come up with a solution to this. in your case, it just may be a bad digitizer or something else touch related. i would try going back to complete stock and relocked and see what that does.

Touchscreen Occasionally not responding

Greeting,
I have a weird issue where occasionally after I unlock my phone, my screen doesn't respond to touches.
The phone works and responds to physical button presses but not touch.
Not sure exactly when it started happening but I've noticed this since last week.
Any idea what might be causing this?
I'm running Android Pie 52.0.A.3.202.

Got the same issue on 52.0.A.8.50. Usually opening the app drawer then hitting back solves it - otherwise none of the virtual buttons work.
Searching the web it seems touch screen issues are pretty common on this phone. I'm a bit surprised there isn't more being said here about it. Some experience delayed response, dead areas and no response at all. I have all those issues. Yes I am on the latest firmware. I bought the phone used with a cracked screen. I checked it out and everything seemed fine. I didn't use the phone, just set it aside til replacement screen came. I should have used the phone to thoroughly check it out but didn't want to go through the set up process as I was thinking of B/L unlock and root. New screen came, put it on and seemed to be working fine then screen would be unresponsive. I did factory reset, software update, software repair, went into settings and made sure sure everything was good there, nothing helped. The center of the screen (it's low and a bit off center) is pretty much dead. To open launcher I have to touch and hold near the top of the display. Touch and hold apps is tricky. Usually the app just opens. When I do get it to hold, I can't drag it anywhere. Also, icons in the drop down menu cannot be rearranged or edited. I can swipe up/down, side to no problem. Whenever touch goes dead completely, the home, back and minimize buttons go grey. Tapping the power button gets them back functioning again. . Function test fail. Free draw lets me make a few seconds of scribbles then freezes. The x and rectangle block draw does the same. Tapping power button does nothing to unfreeze either. The color test pass even the block one where you toggle on/off sections of the screen in blocks. It's really weird. First impression would lead me to the screen but it really acts like a software issue. From what I've read so far this phone uses two different display drivers. I not seen anything on how to change that and it would more than likely mean B/L unlock and root, which I'm not against doing. I would just like to know definitively if it's hardware or software. Any input would be greatly appreciated.
Thanks

Maybe the Screen Connector wasn't 100% clean.
Or not only the screen is damaged.
I heard that the touch problems are mostly fixed with PIE. The closed source clearpad touch driver is..... Hoping Q gives us an further updated driver.
You still get sometimes ghost touches on higher workload or if the keyboard app is slow, but if you have dead spots the hardware sounds damaged.
