Xperia Sola Touch Screen Issues

I have an Xperia Sola having issues with the touch screen, basically it does not allow me to unlock it, I have to use the camera button and take a picture to do it, also, some parts of the screen are unresponsive some times, I read on the sony mobile official forum that this is supposed to be a firmware issue. Also when I try to personalize the screen like adding or removing widgets, you know you need to touch and hold until the widget options appears, that does not work, it will not recognize the touch hold, neither the touch flow works.
It appears the harware is perfectly fine, no screen issues like dead pixels or leaks.
Most people say they took it to the service center and they told them the phone was fine and updated the firmware.
The problem is that If I try to use the PC companion or the main sony website it says mine is using the latest version.
Even thou I reinstalled the official firmware, same issue.
My device is an Asian device, when you restore it, the menus are in chinese, So I'm assuming is a HK phone.
I live in Costa Rica and I know this device has a latin american version.
Does anyone has a firmware that is not the asian one for this phone, maybe I can try flashing another stock rom for this.
I will appreciate if someone can tell me what can this issue be.
Thanks.
And yes, I'm a noob and did not find any related topics about this issue in this site.

Xperia Sola
:screwy: Why so serious!!:screwy:
sola
hi,
me too is having the same issue.I live in India and many users here is also facing the same issue..There is no solid pointer to isolate if its a software or hardware issue.However there is a temporary solution to this problem and is testified by many people including me..all you need to do is keep the phone in direct sunlight for 5-10 minutes.It will work normal for couple of days depending on the ambient temperature and stuff.It will again recur ,all you need to do is sunbath it again
This is not a permanent solution..hope it helps
has anyone found the reason and permanent solution why this touch screen problem keeps happening again after few days ?
after giving the phone to service center has the problem reappeared for again ??

xperiA sola touch screen issue
i have some touch screen problem in my xperia sola
but whenever the upper part of phone screen dosent work i clean it with screen protector cloth and it works fine
screen become responsive without restarting the phone
i think screen protector might be the problem in your case.
thanks for the response. i do not think it's the screen protector because on every reset the touch screen works properly but stops working after five or ten minutes...i have a sony screen protector

I had the same problem with ICS, but i downgrade to GB. First I did the "sunbath", and works, but some apps started to crush. So I decided to go back to GB. Until now, it works flawless. I lose a couple of functions, but it's better than the "sunbath".
UPDATE1: After a couple of weeks the problem came back. Anybody, got a solution other than throw to the garbage the phone?
UPDATE2: Well, I really don't know what makes appears the touch screen problem again, but since I install GB, I got only once that the screen didn´t work and only for a short time. I've been using for a couple of days and I didn't have any trouble at all. I'm guessing that is like a bug software problem, but if someone find a final solution, please post it.
Hey!
Hey guys. I also have the same problem. My service test in touch screen was so terrible. Also behind delete button in keyboard. Lower part right side of the screen. What shall we do?
Additions.
Haha. I forgot the attchmnts
same problem
Same Problem here to.
Anyone know something about this problem?
Anybody got a workaround?
Thanks
Another one with the same problem, mine in the low right side of the screen. Im using the glove mode otherwise its impossible to use it. Somebody with JB, which disables glove mode, has resolve the problem??Im asking this because while its not responding, I restart the phone an enter CWM, and there, its responses perfectly.
So, somebody with this problem, has flashed the any port of JB and resolve this issue??
ok, I´ve tested with JB and it became more responsive but also having the problem.
I left the phone with direct sunligth and now it is ok WTF!!??
have you tried calibrating it? there's an app at the play store if i'm not mistaken..
I have tried everything but 1 thing worked. Sunbathing your sola will recalibrate touchscrren. I dont know how it work but it sure does the job. I'm afraid i have to sell my phone cause i dont want any problems. Now i'm using galaxy s3 mini

SunBathing Works!!!
Hi, Sunbathing really works as a last effort for Xperia Sola
It fixed mine and the time needed for your phone under the sun is approx..1 hour
Dont worry about the battery

[Q] LG Optimus G Menu Button Quit Working

Hello All,
This is my first post on this forum. I tried searching, but haven't found the answer yet so posting here.
I have an LG Optimus G which I bought about 2 months ago from ebay. Phone was in brand new condition and the seller claimed that he only used it once (a few hours) but didn't like the interface so he went back to iPhone. The phone has worked flawlessly until today when the menu button quit working. It is not registering any touch on that side; although the button lights up when the home and back buttons or the screen is used. It is only the menu button that has gone bad. I have not recently installed any updates either. The last update I installed was 11/19/2013. It is running Android version 4.1.2.
Is there a fix to this problem? I am really bummed that being my first android phone, I was starting to like this phone a lot and now this problem has come up!
Any help will be appreciated
Thanks

Welcome to the Community.
Although , I haven't heard about this problem earlier. But in case if that's a hardware problem , then with some tweaks , on-screen buttons can be used , like in N4. It's an alternative.
However , for that the phone should be rooted.
In case if you have warranty available , then you should probably take it to the nearest service center. But if not , then I guess rooting it shouldn't cause any issue , as there is no warranty left to void.
Apparently , is there any app that you have installed recently that is meant for tweaking some settings of your droid ??

Rishi,
Thank you for the welcome and the quick reply. I didn't install any app for tweaking the settings. The last two apps I installed were Mercury Messenger and Skype.
As far as warranty goes, how do I find out if it is still in warranty or not since I bought the phone on ebay? Not sure how long the seller had the phone before I bought it.
Do you think hard resetting would help?
Thanks

If it were a hardware problem, I don't think hard reset will do any good.
But you can try to take a backup and then try resetting it once.
As far as warranty is concerned, you can check with the owner of the phone from whom this phone was purchased on eBay. Of he has a valid bill with remaining warranty then maybe you could be lucky.

You can try this to check if it's really not registering any touch on the home key.
GO through this step. ( I assume , you're on Stock )
In the phone type in : 3845#*970#
It'll open a hidden menu with loads of options for testing .
GO to : HW Device test (options 2 from top)
-> Touch test, ( option 4 from top.)
->Touch sensing test.
You can perform various touch test and buttons test there to see what areas are having trouble registering touch inputs.

Thanks Rishi,
I performed the touch test and yes the menu location is not registering touch. Rest everything else is registering touch correctly. I have contacted the seller to see if they can help.
So, say if it is not in warranty, what else can be done?
Thanks!
If not under warranty then it's going to cost quite a bit. I have no idea about the cost and internals though.
IMO, you can continue with the onscreen overlay button fix, if it asks too much to get repaired.
It'll like as if you were using a nexus 4 with external memory support and lte.

Thanks for your reply, ChummyDays,
Question though; how did you establish the proof of purchase LG requires you to send (I am guessing, you bought yours used like mine)?
I dropped my phone few days ago and now my home, menu and back buttons are not working properly. espesially the back button 'goes on' sometimes and it shuts everything what i open immediately. home and menu buttons just dont respond sometimes on my touch. Is there anyway I can fix it myself? I also thought about the on screen buttons, but couldnt find any tweaks for that.
if your buttopns r broke install xposed, will need root and install gravity box and enable the navigation bar.
