This problem happens on many devices, and unfortunately the only way to fix it is to get the device repaired. Usually this happens because some sort of hardware/firmware error on the board prevents the bootloader from starting; while it is possible to obtain the Qualcomm programming tools necessary to fix the problem, those tools require special images to reflash the device, and those images are not publicly available. Even mobile repair centers do not have these tools, and will generally just replace the mainboard.

[Q] Touchscreen doesn't respond at all

Hi I tried using the search function but I think it's disabled at the moment. The screen on my friends droid always stops responding. And since it's locked theres no way to use the phone. Restarting the phone / a battery pull doesn't solve it. It just stays non responsive. The screen is still working sort of, I can see the battery charge moving and when texts are received they display at the top. But when I call her phone from mine the screen stays at the lock screen. Any help would be greatly appreciated. My friend is stressing over this so I'm trying to help her out.
Hi, I am having the same problem. I tried uninstalling some applications from a custom recovery, and even doing a factory reset didn't solve anything. I also tried booting without the SD card, without any luck. Actually I'm thinking about taking it to Motorola to have it repaired or replaced, cause I have no idea left about anything possible to try.

[Q] Touch issue

At a certain point on my screen, the phone thinks I am touching it.
I dont know how else to explain it but a 'phantom touch'.
Its repetitive and very annoying.
It seemed to start after I flashed some custom ROMS.
I flashed back to stock (2.3.5) in the hopes of it being fixed but it seemed to follow me.
Has anyone had this issue/knows how to fix it?
Thanks
It was completely fine before flashing the custom roms? try re-flashing stock rom, don't root, do factory data wipe from the settings. If its still following you, it might be a hardware issue. and if that's the case, you might need to send it in. It should be covered from the 1 year samsung warranty. make sure you don't have the triangle

It seems to have just gone away on its own. Cheers for the help anyway, would have done this if I still had the problem.
It seems to come back when I flash a ROM.
I flashed the German ICS official ROM (which is great btw), and it seems to have come back.
Hopefully, someone can provide me with a solution, perhaps its a corrupt system file?
Still, it goes away when the phone is charging.
Any ideas at all?
I'm not sure if this is helpful, but I faced the same issue when I flashed ParanoidAndroid yesterday. In Settings>Device settings, there is an option of "screen sensitivity". I set that to 10 (the minimum, ie, the most sensitive). It was then that these phantom touches started. I set it to 100(max, least sensitive) and I couldn't get the touchscreen to register any touches at all. The Spen worked in both cases, so I just used that to reset it.
Anyhow, I believe that this menu is accessible via a key code on stock roms. I'm not sure of it, but it should be. Look around in the tips and tricks thread, all secret codes for the Note are listed over there. Then just change sensitivity to 20.
Hi, I think this seems to be the trick.
I was unable to find the code to access the settings menu you described.
However, I installed TouchScreenTune, and that seems to be working for the moment.
Will post my results in a few hours or so.
Thanks

Also, If you are able to remember/get the code that would be great.
I found a list of the codes but none look like they'll be what you mentioned.
Thanks again

You're right, I couldn't find one that'd help either. Hmm.
Do you still have the problem?
It hasn't gone away, but I think the frequency at which it occurs has reduced
Any other ideas/any other way to do your previous method?
Cheers
Okay so here is all the information I have.
No matter which ROM I flash, the issue of the random touching continues.
Ive tried without root, and tried a complete reinstall (by formatting all data and storage)
I found a CWM restore I made 6 months ago (long before the issue started). That didnt work either.
Things that DO work:
TouchScreenTune seems to greatly reduce the frequency at which at occurs by decreasing the sensitivity of the screen, however, it makes it harder to use the phone.
Plugging in USB stops it completely, but when its removed, the issue comes back.
I thought since it is following me through different ROMs it is a hardware issue.
Does ANYONE know a fix/heard of this before?
At the moment Ive resorted to using my old IDEOS (oh god) and have begun working towards a warranty rectification.
Thanks anyone who can help
Update from Samsung:
Issue due to motherboard/touchscreen
Cheers for your help

Three annoying issues, help please.

I don't know if any fix for theses issues were posted or discussed before but I need some help with my S6 Edge. These are my issues that appeared out of nowhere today:
Touch button doesn't light up anymore no matter the setting or if power save mode isn't on or off.
Auto brightness doesn't work
When making a call the screen turn off, proximity functon is not working if I turn the screen back on during the call using the power button
I already tried resetting the phone as a new device, verified all sensors using the code *#0*# and contacted Samsung with no luck so far. Samsung told me to change the phone for a new one but I don't think the issues are relate to hardware but I'm not sure Maybe related to an update? I never rooted my phone. Any help before I go back to AT&T for an exchange? :crying:
Anyone?

Well, I performed a factory reset if that is what you mean. Never rooted my phone before.
Tried to flash stock ROM via ODIN but it failed everytime.
Finally I did, flashed stock with G925AUCU3BOI2 and issues persists. Returning to the store for warranty.

Screen has stopped working - help!

Hello all,
I have a Xiaomi Mi Mix (256gb) and I haven't changed anything since it came out of the box in March.
This morning, after working fine in the car, the screen stopped working. There are several grey lines at the top of the screen and the notification area is flickering, and I now can’t even unlock the screen. Nothing else will work. I’ve turned it off and on and rebooted multiple times, but this hasn’t done anything. It has never been dropped or thrown about.
Any ideas? I’d like to avoid doing a factory reset, but I’m sure that’ll be my next step (although I’ve no idea how I’ll do that!). I’m a complete novice when it comes to doing anything complicated with phones, so I’m in dire need of help. I’m not desperate to send it back to China!
I really hope someone can help…..
Graeme
Seems like hardware problem.
But to check if its a software problem you have no other choice than factory reset.
Thanks. I suspect it is too, but hopefully a factory reset will help.
I tried to follow these instructions at Hardreset .info - but rather than the recovery screen I just get a screen telling me to plug the USB in and to go to pcsuite.mi.com. Fine for backing up, but not resetting! Any suggestions?

Was wondering how you would do that with no touch screen. Tried mi flash tool? Or fastboot? Not sure how far I would go if having to return to vendor. Is it possible the cable wasn't connected properly from new and just totally came off. If you're brave could take battery cover off and take a peek. Don't know what the answer is unfortunately.

Nokia 7 Plus - Screen Freeze - Lock and Unlock to make it work

Hi Folks,
I have got a Nokia 7 plus and since the day I have bought it, I am facing a strange problem.
Every now and them the screen freezes and only way to make it work again is locking and unlocking the phone.
I can say the screen do not respond to touch because the buttons are working properly in this case.
Tried resetting the phone, installing Android P, Rolling back to O, but nothing works. the problem still persists.
Curious to know if anyone else is facing such problem or if anyone has got any solution to fix this issue?
It a hardware problem i believe. Coz even i had the same issue. I immediately sent it to service center which was luckily nearby my home. They took a video of that issue and sent it to Nokia for replacement. They approved my replacement and gave me a approval letter and requested me to visit the shop where i had purchased the phone. The shopkeeper took my old phone back along with all the accessories and approval letter and within 5 mins they gave me a new unit.(note: the service center person told me that if you have purchased the phone from a store then you have 14 days replacement guarantee in case if any issues persist post format or tests).
I have the same issue, tried all methods you mention to make it work normally without succes. I dont know if it is a touch hadware problem because it happens very ramdomly and works instantally and normally again if I lock and unlock the screen
Some days not happens, another days happens very frequent.
Another fact, every time I installs some Factory image (Android P developer preview, Android 8.1), the touch not give problem at all for aprox 2 days or more.
I'm very frustrated with this issue.

This is the Nokia 7+ quality problem, go to the after-sales service to replace the screen for free.
So i got my device replaced and for sometime, it did not give the problem but after 3 weeks, i started experiencing the same problem. New device also becomes unresponsive at times and then i have to switch off/on again to use it. I updated OS to Android P DP3 last week but issue still persists.

I think we can clearly consider this as a hardware problem in that case.
i have same problem with my Nokia 7+, I gave a chance to nokia but I'm already starting to change my mind, the bootloader can not be officially unlocked and now the problem with the touchscreen, a bit disappointed, I hope hmd solve these issues and if not, buh bye nokia.

Sadly, this is not the case here. I did a clean install of the latest developer preview, and I still experience an unresponsive system. Right after lock/unlock it works again.

Seriously ur device need a service centre
It happens to me sometimes while uninstalling an app. Device freezes and doesn't respond. After like 10-15 seconds, it uninstalls the app and start responding.

I have similar problem.
When I want to clear data for the chrome through the settings, device goes mad, most of the time freeze and its difficult to restart it.
I thought they fixed with august security patch, but no.

Yes, it happens to me as well. Let say Chrome has 200mb cache and if I click on Clear Cache, device freezes.
I used to face this problem quite frequently, but I haven't seen it in quite a while. For this reason, I'm pretty sure it was a software related issue and not a hardware one, as a hardware problem would be unlikely to go away, but a software one could be fixed with updates.
It started to happen on ly device today. I have the august security patch and my model is ta 1055 so i don't think the problem is solved yet
Cleared chrome cache. Device freeze for 15 minutes and rebooted. On Pie dev 4
There are so many seemingly random issues with this phone, I can safely say that I hate it. I never know if it's going to take a call (unresponsive soft button), or if the person on the other end will be able to hear me (mic just randomly stops working at least once a week). Freezes a few times every day. Won't allow push email notifications after (or during) sleep, have to reboot. The list goes on......
Going to turn in my device for repairs. It's taken Nokia long enough to come up with a software solution. On the Nokia forums there are several people who were helped with a touch panel repair.

Already sent back the device for repairs twice, each time they sent it back with just a reinstall of an older Android version... claiming it would be fixed.
In Europe, there's no Nokia repair, so another party is taking care of the repairs. It seems like they are not really aware of the ongoing bugs/problems of the device, which makes it extremely difficult to get them to actually repair the device properly.
First time they even told me they "replaced defective hardware", when in fact the hardware was not touched at all.
I managed to record the issue with another device, and showed it to the vendor.
Now they're offering me a refund. It looks like this is the best option I can get from them.
Really sad though. I was hoping for them to just fix it. Apart from this problem, it is a really good device. There's not really a good alternative in the same price range.

Im having trouble unlocking my device, I tried the finger touch to unlock but it did not unlock and the phone is unresponsive even on pressing the power button. I tried to force restart by pressing and holding the powerup button and power nutton simultaneously but still no result. Also I could see a red led light at the lefthand side of speaker on top.
Note: The device was fully charged.
can someone help me with this Issue please
