Constant Touch Screen Malfunctions

Hey,
I'm sorry but I can't find anything on common touch screen problems..
My touch screen is constantly just not working. It started I think after a droplet of water(one singular drop) fell on the screen for a second(right in the middle) and it stopped working for about 2 hours..Since then I will have it working fine for a couple days, then it will just simply stop working. No response to anything at all. I can restart it and sometimes it will work, sometimes it won't. I usually just end up sitting it down and when I come back 20-30 minutes later it works again.
Now, today, it has been doing it constantly. I can get it to work after multiple resets and stuff, but then it will stop again. Works some, then stops, etc, but I am not doing anything difference except resetting it..
Is there anything where I can troubleshoot the problems with my screen and see what is wrong with it?

Well I don't know how you searched but there are multiple threads on touch screen problems. Here's one search I did using the Google sticky post:
http://www.google.com/search?as_q=t...rum.xda-developers.com&as_rights=&safe=images
However, your problem is curious as it's the opposite of the one many get. Some folks find when the device has been on for a while and gets warm then it's screen stops responding. You have the opposite, it stops working and then leaving it brings it back again. I suspect though it's related. By leaving it for a while it cools down and works again.
It's not good news and we have no reliable fix. It is not thought to be a touch screen fault (for many folks anyway) so changing the screen may not change anything.
If it still has the problem after a hard reset then it's a Warranty replacement or repair I'm afraid.

G-Sensor and call problems

Well first of all I love Android, but I have some problems. The first problem I have is the G-Sensor, it used to work, but suddenly it stopped working properly. Now when I want to rotate the screen I have to hold it the way I want it to turn for 20 seconds, is there a solution to this problem?
Now my second and most important problem is calling. I have multiple problems with it. One of them is when I'm being called while the phone is in lockscreen I try answering it but I have to wait ten seconds before it actually answers, mostly the caller is already connected to my voicemail. My second problem is the End Call button when is press it, it says ended but I also have to wait ten seconds before it actually ends the call. Does anyone have the solution to these problems?
For further information, I use Froyostone 3.2. And sorry for my poor English.

Could anyone please help me, sorry for the bump?
Also I notice that my hardware buttons light up randomly.

I also have the same problem. Well at least with the g sensor. Running android 2.2 the problem with my g senor is whenever I flip messages they will not flip back. (along with anything else that does flip) I've done the re-calibration on the phone and this is what happens.. x axis is fine y axis either stays all the way up or goes all the way down. When I start the calibration the y and x axis both go to the middle but after when calibration is done the y axis goes right back up or right back down.
Thanks in advance if any one can help.

The same thing happens to me when I'm trying to calibrate it. Also have you tried holding your device for 10-20 seconds the way you want to turn it? This solves the problem for me, but I would like it to happen a little faster.

I calibrated the G-sensor when I first put on Android, bad mistake, the Bubble just stayed at the top and nothing rotated properly. The Sensor worked fine in WinMo so I guessed I'd screwed it up.
Since read somewhere on here that you shouldn't Calibrate it in Android.
Had to reinstall Android fresh to get it to work again, but its been working fine since.
Was on froyostone 3.1, when I reinstated upgraded to 3.2, all is great

Okay that could be the solution. Do you also know if I need to put a new data image on it. I would like to keep my old one, but I thinks the problem lies there or doesn't it?

You might be able to calibrate your G-sensor in Android. Click the calibrate button and place your phone screen down on a flat surface. For some reason, calibrating only seems to be working when you face your phone screen down. It did the trick for me, fixed the offset and it's working just fine now.

I tried changing the data image from 3.1 to 3.2 but the g-sensor was the same, i just used Titanium Pro to backup the data i wanted to keep and reinstalled.
Try the Phone on its screen re-calibrate as suggested, ive read that may work as Roeltjuh suggested, but that was after i had reinstalled

That seem to do the trick, thank you!
Does anyone have the solution to my other problems? Also I've noticed a new problem, sometimes my WiFi won't turn on till I reboot. In the settings menu it says shutting down WiFi. But its already been shut down, and because of the loading it takes to shut down wifi, I can't turn it back on and my data connection says that it will be turned on when my WiFi is shut down. So I always have to reboot.
Sorry for all the questions, but I believe some of them can be fixed and they're too annoying to ignore. And again sorry for my poor English.

[Q] touchscreen issues

i've had this phone for a few weeks and everything worked fine. I flashed chucky's rom, and ran CoreDroid Evo Supersonic from the SD card. it worked great. yesterday, the touchscreen stopped responding if i'd wake up the phone with the red button, but the others worked fine. Now, i have to try 10-20 times with any button for the touchscreen to work. The same thing happens in Windows Mobile. I just flashed to a different ROM, and the same problem occurs.
could this be a radio issue?

Well this is something that helped me, cant rly tell if my fix will work for you but try this. Drain your battery until the phone shut down on its own and then charge it fully. Do this few times and hope to god it help

i have absolutely no idea how that would work. i'm assuming you had the same problem as me?

Yes ofc it's a known problem, you can see many post about it. Touch screen wont wake up when you use end call button, its a hardware issue. Well the best solution to its to send it back for replacement, but I didn't have that option unfortunately.

but it won't wake up with any of the buttons i press, not just the end call button.

Screen not working! Anyone got the same problem?

My optimus 7 works fine after Mango update till these few days. The touch screen just stop working, I thought it's the hardware problem at first, but after I reboot it few times, it works again.
Then after working for one to two days, it happened again. No matter how many times I reboot it, just not working. So I leave it for a night and plan to bring it to repair center, it suddenly works again in the morning.
Then it works for another 2 days, I even try hard reset this time, still not work. And again, works fine after few hours. Now ..., it stop working. So annoying.
Guess I need to take it to repair or just a software problem???
Anyone can help? Thanks.

i have the same problem. It would be second time my LG optimsu need to be repaired
