g2x screen calibration issues!

is there anyway to calibrate the screen? im having some calibration issues with my g2x and restarting the phone doesnt help!

I just looked through the hidden menu list. I don't see anything about calibration.
Out of my last three phones that had touch screens, Ascend, Evo, and Indulge, It seems like only one had a calibrate screen option, so I don't think it's real common.
What problems are you having? I've noticed a lot of times with my G2X that when I push a link, it highlights right above it. But the link still works.

I have issues as well, there are no calibration settings in Hidden Menu. Sometimes I press on the screen and it hits something else. Sometimes, I'm not even TOUCHING the phone and it will, by itself, select and enter into different apps on my screen. I thought I had a virus on this thing.
I checked around, other people are having these issues and have NO real fix for it. It has to be an SW problem. When I first started using my G2x, there were no touchscreen problems like there are now. Guess I'm gonna have to change my signature on the G2x away from "so far no issues".

I've noticed that the edge of the screen is very very sensitive. I'm constantly opening droidtv when the app drawer is open. It's right at the bottom left. My fat fingers overlap the edge enough to open it. Makes me laigh.
Also, I've set launcher pro to scroll the apps up and around like it is in the stock drawer. It cracks me up how it is so sensitive that you can open the app while the icon is scrolled up and around the corner. Even when it's two rows back and especially out of the way. Try it.
I know you said you weren't touching the phone, but maybe some of these times were when you were just holding it?

Yeah, when I'm holding the phone, the bottom of my palm near my thumb is close to the edge of the screen, and it registers as if I were pressing on the screen with my other fingers.
The screen jumping around randomly, I can't explain it. And it does happen when I'm not even touching it. I would put the phone down and watch it go, entering menus and apps and pressing all kinds of things. On one of the forums I linked, someone said to remove the battery and let it sit for a few seconds, then put it back in. So I've tried that, and so far the touchscreen isn't acting possessed anymore. This isn't a constant thing. It's just happening at random times on my phone, it's leaving me confused lol.

I've just began to run into this issue. It most apparent when using the keyboard, and switching keyboards doesn't even seem to help.

CM7 fixed the calibration and touchscreen issues long long long ago.

[Q] Quirky Touch Screen Problem

One of my phones is an HTC Surround that i don't use that often but still want it to work. To the issue though, each time the phone is turned on (not powered on, just woken) the screen refuses to work on the right side. In order to get past the lock screen you have to swipe up on the left side. After that the right screen becomes 'active' only after you swipe the left screen again. The home button and the search button on the phone only work after sliding the left side of the screen down and hitting the back button, once that task is accomplished the entire phone works perfectly and no more issues develop. This has been driving me crazy trying to figure out why its doing this. I reset the phone twice, both through the reset in the settings and doing a hard reset. When neither of those attempts worked i put it in bootloader and flashed this release (http://www.filefactory.com/file/b48...S_1.03.502.07_5.51.09.06_22.30.50_RELEASE.exe) to it and it still continues with this wierd touch screen issue.
I could probably just throw the phone away and not care but i'd prefer to fix it and sell it. Plus its driving me insane trying to figure out the issue.

[Q] screen wierds out

I've had an odd problem with my 820 almost since getting. I'm hoping one of you geniuses have some advice.
When I turn it on it works perfectly, sometimes for hours. Then the screen goes blank, and then random pixels begin to appear, starting at the top of the screen. Outdoors rather than random pixels the screen goes almost totally green. Strangely, if part of the screen is obscured the green only covers rhe exposed area.
Pressing the on button repeatedly usually brings back the lock screen and reset (on+down) fixes the problem for another few hours.
By the way, eventhough I can't see the screen the touch sensor works. For instance I can hold theon button and then swipe downwards to turn off the phone. I can also answer and hang up using earphones.
My daughter who purchased the phone said it worked fine until the amber update. I had hoped the black update would fix the problem but no change. I found some posts from people with the same problem who sent the phone in to be fixed and got it back in the same condition. I really don't want to go through the hassle unless I expect to get it back fixed. I'd rather try fixing it myself.
My question is whether this is a firmware problem an whether it is likely that re-installing the stock black rom would do any more than the ota install that occurred automatically did (or didn't do).
Any ideas?

Nobody?
By the way it seems to happen only, or mostly when in standby.
I installed an app that displays a clock and doesn't allow the phone to go into standby mode,
and the problem doesn't appear to occur (unless I forget to leave the app on top).
I would set the phone to standby = "never" but the option isn't available on my phone, though
I understand that there are those with the standby = "never" option.
Any idea if I can set standby = "never" with keyboard commands, perhaps?

[SOLVED] Half of the screen flickers black between unlock and home screen

Couldn't find any similar topic except in forums for s10+, OnePlus and other phones. Sorry if I missed anything.
As in the subject, after unlocking, approximately half of the screen flickers black and goes to the home screen. It takes less than a second. Always top half, bottom half shows home screen right after unlock. This does not happen on each unlock, but also, there is no pattern - it can be after 5 or 30 unlocks, it can be after 5 minutes or 10 hours of not using the phone. It started mid-July and not only annoys but is starting to worry me. Solutions from other threads didn't help. For example:
Fingerprint sensor problem - I don't use it, I have pin lock.
Samsung Pay issue - I don't even have it available, so, don't use it either .
Animations - setting them off did not help.
I cannot guess anymore what would be the cause, if it's some app which wakes up after unlock or what else. The only thing I've changed (except updating apps) was adding another sim card, but my tiny little brain cannot find connection. I didn't test removing it as I need this sim active and don't have backup phone right now. Also, I would really like to avoid resetting the phone...
Did you experienced anything similar?
Thanks a lot for any help or suggestion.

are using Samsung or some third party launcher. Did you wipe cache? Latest firmware updates?

Yes, I did both, firmware update and cache wiping, no change. I'm using stock launcher.

did you try in safe mode to exclude some app causing it

Yes, I tried safe mode without success.

i would take it to Samsung repair centre if pos

Thanks for trying and all the steps. There's nothing like that where I live, neither any advisory place except for hotline. I can drop it at their service but will need to wipe it down before, which I keep as the last resort. I'll keep waiting for another firmware update and if nothing changes then I'm willing to do the hard reset. I just hope it's not a symptom of some virus - I'm trying to be most careful, scanning device periodically, didn't root, so I naively count on being safe...

i don't think it's virus. fingers crossed it's just software issue

hi again, just to let you know, I think I know what was causing this flickering and now I feel silly . Home screen rotation. I had this option turned on, and it's possible that sometimes, when I put my phone on the table, home screen rotates to horizontal position. Of course it locks after few seconds. I've noticed it completely accidentally, because one time, when screen flickered black there was slow-motion rotation animation in the background (which I've never seen before). That's why flickering was completely random to me, not connected to any type of notification whatsoever. Well, it's not, it has a pattern . I've checked it plenty of times and each time I lock my phone with home screen in horizontal view, but unlock in vertical, half of the screen is flickering black. That's it, at least I believe it must be this, because it happens each time and never when I lock my screen in vertical position.
Once again thanks for all the help!

Question how to fix random black screen after opening phone

My z-flip3 5g has a strange problem. If i close it (by folding the screen closed), then after opening (unfolding) the screen and touching the right side button/fingerprint reader to unlock it, i hear the quiet "click" noise that indicates the phone is unlocked, but the screen stays black. i then have to repeatedly push the lock button on the right to lock the phone again and unlock it again. after several attempts the screen finally turns on. sometimes it will go black a few seconds later and the same issue continues. but other times the screen will stay on and work fine.
i have noticed that if i do not close the phone (folding the screen together) then i do NOT encounter this issue. the phone screen turns on when pushing the right side button (or touching the fingerprint sensor) and everything works fine.
this issue started yesterday, a system update installed yesterday as well, could it be related?
i already restarted many times, booted into recovery mode and wiped the cache. nothing has helped. the only way to avoid the problem is by not closing (folding the screen shut) the phone.

I have same behavior. Did you solve this problem?

Unfortunately no. Did a factory reset, hoping that would help, but the issue persists

Mine has recently started doing the same. Last update was right before this started several weeks ago. I don't have mine set to require fingerprint, it should just turn on after opening. If I open it partway, it will turn on, then turn back off when fully opened.

hi,
i have same problem, it's software problem?

Not completely sure about that. They update this thing so often, it could be coincedence that it started shortly after an update. I want to try blowing out the hinges as I've got some dust under there that I hear when opening the phone. Definitely not a phone to put in your pocket after working in the wood shop!

and don´t take it to the beach either!
What is also strange is that when I close the phone and open it a few seconds later, there is no issues whatsoever. However, if I leave it closed a few minutes, then when opening it, the problems with the screen staying off happen.

Yes, definitely don't take it to the beach!
@netridah , mine is doing exactly that. Which makes me wonder is it a wake issue, or a mechanical/sensor issue with the hinge.

one more to the bill
I checked the flexes and I warmed up the logic nothing works

I have the same issue: Flip 3 - 5G with OneUI 5.1 - 1 April Patch level
When I open the phone I eventually see for less than one second the lock screen, the goes black and unresponsive.
Then I have to press the button to turn the screen off (even if it is already) and then re-press the button or use the fingerprint to turn it on and it will work (eventually, sometime I have to do it a couple of times).
I already googled it on many forums but no solutions, I've tried to:
Disable the always-on display - no result, at first looked like it did the trick but the day after was having the same issue.
Check all the updates of the system components like always on-on display (settings --> lock screen --> always on display --> info), no help everything is up to date.

Hi,
I have the exact same problem, only difference is that I'm on the z flip 4.
I get the black screen and sometimes when opening or closing the phone the screen can flash in a bright yellow or green color.

I got a motherboard but the problem continued
Next step changing screen is very expensive at the moment

This is driving me crazy - also started the day I updated to OneUI 5.1.
Hoping for a solution soon!

I am also encountering this problem, I went to samsung repair shop 1 month out of warranty, sales person said it is a screen issue and needs to be replaced for 430$. Mine was before the update, i took mine near the pool, got wet maybe, as the alarm for usb charging mentioned unplug it immediately, day after it began randomly dark when phone is openned fully. Zflip 3

Oh just an update, i did some tinkering today, Good lock all updated, disabled clockface, sprayed some contact cleaner on power button, and hinges, fold close and open for a minute or two, fell asleep for 1 hour, and when I woke up, my screen works back to normal, it wakes up when unfolded, no more waiting or hitting the power button several times. hope this stays like this.

Hi, few days now, I still have occasional blacking out, I've tried putting my phone on safe mode, and this seems to solve the problem. I suspect it may not be hardware fault, but 3rd party software, "good lock" or something else that conflicts wit one ui, that makes the flipping open lag waking up. Contact cleaner used for electrical stuff

Didnt use my z3 for about a week let the battery drain.. then charged it too 100% without turning on the phone.. my phone back to normal now.. hope it works for you guys

Hello,
I am using Z Flip 4 and last night I started having this problem as well. I can confirm 100% that my phone has no hardware nor a history of impact of any sort that's why it's really frustrating having this kind of problem.
Has anyone already found a resolution for this problem?

Z flip 4 here also. Had the same problem with the screen. Took the phone to Samsung and they changed the screen, frame and back panel's for free under warranty.
They said it's a hardware issue.
So better to take the phone to Samsung.
