touch screen problem - JAMin, XDA Neo, S200 General

hello i have a problem with the touch screen...sometimes the touch didn't function corretly and seems to be disalligned.i've alredy tried to fix the problem with a hw reset and with the allignment option but nothing happend.anyone know how to fix the problem?
sorry for my bad english....

Try using the touchscreen again while pinching/squeezing the back and front of the phone together on the left hand side of the phone. Does it work as normal doing this?

yes it's work but i must doing a very high pression and when i relese the touch screen didn't function.

Same happened to my Prophet, all of a sudden the touchscreen failed.
IF ITS STILL UNDER WARRANTY SEND IT BACK FOR REPAIRS OR REPLACEMENT. Otherwise try cut an old credit card in half and place one half between the battery and back cover of the phone. This will preform the same function as if you were squeezing the phone like you did before (except hands free).

Dust
Look for small pieces of dust between the digitizer and the chassis, this can disalign the screen too.

Touchscreen doesn't work anymore

Well, plain and simple is that my touchscreen doesn't response to any touch reponse but the screen is working and everything else
I recently bought a white G1 housing kit on ebay and decided to take the risk of opening up my G1 to replace the housing of my black G1 to the white one, but turns out the white case for the screen / menu buttons arent correct so i scraped those and just changed the keyboard and menu button keys to white and put everything back together properly and exam each part and etc.
so i put everything back together and turn on the g1 everything works fine but the touchscreen doesn't work, is there anyway i can fix this?
life is hard using the G1 without a working touchscreen lol
thanks again and i don't think my screen is defective just wondering why it doesn't reponse to my touch
thanks
Once I was walking around in the heat with my G1 in my BDU pocket for like 4 hours, and it obviously got really humid in my pocket, and my touchscreen stopped responding. I let the phone just sit off for a while and after about an hour sitting in my room, it started working again. But I've had several instances where the touch screen has been less responsive/not responsive.
My guess based off my experience would be that some ambient moisture may have gotten into the phone when you opened it up. How long has it been since you put it back together?
Any update on this?
you said you had 2 g1s, right? so take the phone apart again and replace the touch screen.
the touch screen is separate from the LCD, so that wont affect it.

[Q] Incorrect Error Diagnosis at HTC Repair Centre

Hi,
I had the following problem with my HTC Diamond 2 (it might have got wet & it might possibly have had too much pressure on the screen)
Problem:
The mobile boots ok and the normal buttons at the bottom work fine, as do the volume up/down buttons. The display, however, has what looks like the newton rings and when I press the display it detects a 'press' about 1cm to the left of where i pressed. This means I can't use the right hand side of the display and also can't enter my pin.
Error Diagnosis: (from Arvato Services in Germany)
Mainboard is defect. Cost to repair = € 303.17
Is this possible ? If there was a problem with the mainboard then I would expect to see other problems - and at present, I can only see that the touchscreen has a problem.
Please let me know what you think, thanks in advance !
(ps there should be a question mark at the end of the 'title', don't seem to be able to edit though)
Based on your description and from what I've read, it's definitely the digitizer.
It is possible that you have a damaged board, but regardless, your digitizer is bad.
I would attempt to replace this yourrself then see if everything is fine before sending it to repair.
I had the same problem!
The screen was getting worse in alignment over a time frame of a couple of days. If replaced the digitizer and screen and all is back to normal ..... however it seems to work better then ever before.
The only problem left is dust between the digitizer and my screen, but this is my own fault since I didn't glued the screens. I'll re-open in the next few days and use some silicone to close the gaps. Mainly the volume key has an opening to the outside.
Good luck with the replacement!

[Q] Broken touch screen, NO warranty.

Hello, I was wondering if anyone can help me. My touch screen broke today and I received a text message and have 3 numbers which I need which were not synced before the damage which I now cannot get access too. The phone boots fine but the only buttons that work are the volume, power and reset.
This phone cannot be sent back to the manufacturer as the break was entirely my own fault.
When you plug the phone into any computer it defaults to the "disk drive" option so can only access sd card data.
I hope there is some way I can get the important data off it?
Thanks!
Fixed for long enough anyway!
I assume that no one has any idea about this one. I have managed a quick fix and I hope it can help others.
Essentially my screen looked like it had a REALLY small amount of liquid between the top peice of plastic (the bit that you actually touch) and what I would assume is the digitizer. After a few days the whole screen looked a little shiny and the touch screen and soft keys did not work.
The way i fixed this was to get a thin pen knife and slide it around the edge of the screen, between the two pieces of plastic along one side of the screen.
After this the screen worked again just as it did before.
I suspect that there was already a small hole/gap allowing condensation to build up between the screen and the digitizer.
I hope this helps someone.

[Q] Replaced screen problems (video)

Hi all ,So the story goes is I had my cracked screen replaced by my insurance 2 months ago. My new screen was fine up until a few week ago when this started happening..
youtu.be/lXv5xBA-r9E[/url]
Basically when I press hard on the top right of the screen I get ghost touches all over the screen. It also happens all the time when I use a case because of the pressure on the top right part of my screen.
I noticed that I can get my fingernail in between the 2 parts of the phone on the side. I really don't want to go a month without my phone again so I'm reluctant to send it off to insurance. Has anyone had this problem? Should I try a phone repair shop? Does this happen if a screen isn't fitted properly or is it another problem? Thanks
Seems like a faulty digitizer
More info... The screen works fine when I press it normally. It only goes crazy and when I press slightly harder or if there is a case on

Screen becomes unresponsive to touch frequently

I've searched a good bit and wasn't able to find any information regarding the exact problem I'm having.
Bought a used G6 for starters
No water damage indicated by the sticker
The phone works great on the home screen and app drawer
I turned on dev mode to show touches
When you're in the camera it will stop responding to touches, you can still take pictures using the side buttons. The screen will become responsive again after a couple minutes. This whole time you can take pictures and the screen is functioning just not responding to touch
This happens also when you're loading web pages, even a Google search the screen will stop responding to touch and then eventually start responding again for a short while till you load another page or start moving around the page too quickly it seems. However again the screen is functioning, video previews are playing, just no response to touch.
Loading a game like Asphalt 8 the phone doesn't respond to touches until a couple minutes after the game has been fully loaded.
Even after a hard reset/factory reset the screen will sometimes be unresponsive upon the initial welcome/setup screen and then it will become responsive and you can go through the whole setup without an issue.
Any insight? Any suggestions? If I can't figure it out I'll just get rid of it but it's in great condition a shame it just doesn't function properly.
Thanks in advance!
Looks like some sort of hardware issue...
But before you start to worry...
This might sound like a stupid question but have you tried cleaning your screen with some cleaning solutions?
Sometimes dust mixed with dried sweat can cause severe touch responsiveness issues even if the screen looks like it's clean.
This is an older thread, but maybe I can help someone.
I replaced a touchscreen on a LG G6 and saw that the touchscreen did not work if the back cover was not mounted correctly and the data transfer between the phone and the fingerprint sensor was interrupted. This may be a common problem for users because the connector is small and the back cover is attached with a double-sided tape nearby this connector. It seems that the touch screen is disabled by the phone software without the back cover.

Thank you so much for this comment!
My gf phone had problems lagging and becoming insensitive to touch, the problem got worse and worse, almost never responding anymore. Performed a factory reset etc, didn't help.
After reading your comment I tried pushing on the back cover while swiping. Now I'm able to revive the phone after pushing hard on the top and bottom left corners, of the back cover.
Thanks a mille !
Lg g6 has back panel from glass and under it you have contact for fingerprint sensor.Somehow if the back panel is loose it can cause touch fail,and you cant use the device touch function!
--->FIX:
So you will have to turn screen off using back button,and then try to press back glass on left and right side of the camera lens !
Then simultaneously press the power button and try to use the touch .
If it does not work tru again around camera lens and turn off screen each time you press the back glass!
For me it worked !
