Usually the touchscreen stops responding when eigher :
a)Phone is overheating (Was it very hot?)
b)OS (Android) is lagging like hell (Have any Resource whore installed?)
c)The touchscreen might be failing.
In 99% of the cases its eigher a) or b).
So check your apps if you got anything thats using all your phone's resources and also check if the phone gets very hot (Have you OC'ed it?).
Respect

[HELP] i am planing to buy xperia mini (ST15i)

i am planning on buying XPERIA MINI soon but i've heard that it has few problems(global) like
* battery overheat
* strange activity of capacitive buttons(menu & back button start without even touching them)
due to these problems the phone seems barely usable
is this true , if yes did installing cyanogen-mod rom solve this problem ???
check this link this is a global problem : http://talk.sonyericsson.com/message/112523#112523

The phone works fine with me. It's definitely usable. Just because one experiences a problem doesn't mean that everyone else does.

I dont have battery overheat. Capacitive buttons accidentally start only when I breath on em.
Plus I edited my keyboard layout so I can only unlock with power button.

thanks for your answers but i am referring to ST15i (without hardware keyboard)
but this is a global problem almost 44 members are shouting their problem at sonytalk @ http://talk.sonyericsson.com/message/112523#112523
Like you, my last unit was wildfire and it wasn't charging, there's a problem with the mobo and the warranty is expired a week after it happened that's why I chose xperia mini with Adreno 205 compared to wildfire S adreno 200.
Other users are definitely having problems with the capacitive buttons namely the back and menu key. So far, I had my xperia mini for over 3 weeks now and it doesn't have that problem. Honestly, I'm worried that the problem might show. However, from the moment I had the unit, I charged it overnight and been doing it ever since. I've been playing games with it like nfs shift for more than 30mins and the battery doesn't overheat the same as with charging it overnight. Overall, it's a fairly powerful phone and can play HD games with no lag at all. The only thing I don't like about it is sometimes I struggle reading texts while using its browser.
And oh, the sound(xloud) is awesome especially while using its stock earphones.
thank you for the info ....i am going to wait until sony finds a solution to this problem
you are quiet a lucky one ...i hope you wont have any such problems with your device
Dude its the best phone ive had. Coming from galaxy s
Hi. May i know when did you guys buy your xperia mini? I'm planning to buy the phone this week then I read the problems. I'm choosing samsung fit, lg optimus net and xperia mini. obviously, xperia mini as an edge to them but because of the problems I read, I'm having second thoughts. Help!
Like I said before, I bought mine for over 3 weeks now and doesn't have any problems(hoping it would stay that way). And I'm very happy with it.
dude, it support multi-touch? ?how many finger support?

Maybe does not seems to be so bad, but it's even worse: ST15i become totally unusable, when the capacitive buttonns are going crazy.
My phone has worked just fine for more than one month, but now it works only until the temperature goes above 34-35 celsius degree. Then the capacitive buttons starts activating, and the phone does not respond to any other command untill the temperature drops below 30 degrees.

yes but not my mini ;-)
I also bought my mini september 9. And so far so good, as it doesn't give any of the capacitive buttons malfunction.
Me too bought this about 1 month ago and didn't have any problem. the only problem was LCD brightness which was flashing sometimes in medium light places. but it solved after upgrading to 2.3.4
it's a good phone with many good features and suitable price
well, can we put some geographical or Weather classification here ??
i mean hot countries having this problem, while COLDER ones not having them ???
or it's irrelevant ???

I saw in KA sony rom thread you also have this problem. Thanks for making this as separate thread to discuss this issue and find solution to this.
I was searching online and I found many have such problem and have all random solutions to it. like - offline charging the phone, landscape rotation toggle, headphone jack, press bottom of the phone hard etc etc but nothing worked for me
check out these links problem is discussed here but no sure shot solution.

Some work around for answering phone quickly till problem solves - there are apps to answer calls just by pressing button.

My call screen locks up very occassionally, but for some reason if you move the reject slider, hold it and slide it back without hanging up, it will come back to live. Never had a problem with lockscreen.

I still have that problem, but only when my phone is charging... Whn I touch the screen it would jst randomly touch anywhere! I used the show touches option in developer settings in ICS and everytime I touched it.. It showed the random touches too .. But all this only happens when my phone is charging. Rest of the time it works completely fine.

yes, this mean's your phone touch panel is going to die. I also have the same problem, when i connect my phone on charger touch works randomly, when i removed it comes normal. This because i remember i used a duplicate charger and also tried different data cable which is same like SONY cable. So i feel this is main reason my touch panel gone and it is now on service center .
So if you do these all, please stop doing it. And use always SONY's Charger and Data cable to save your mobile from "TOUCH PANEL ISSUE".

My phone was with them for almost a month... Later while recieving the phone I noticed my phones front panel was damaged(the lower right of the front panel had broken paint) and the display electronic strip which should be covered was left exposed.. So they kept my fone for like 2months more.. No jokes! Contacted them every alternate day.. They always had the same answer.."we have ordered the parts.. It should be dispatched in a day or two" Thn finally I got my phone back with the front panel replaced.. But the strip was still exposed! I dint want my phone to stay there a month or two more.. So I let it be how it is! IMO I chose the wrong service center... There wer also others who complaining about their service... So now my phone has the touchscreen issue and a bit of the display electronic strip exposed inside the battery cover. Gave them my phone for an issue they gave me back with two!

[Q] Odd touchscreen issue

My wife's P7510 has started to act up. The touchscreen is jumpy. When i go into the development options and use the pointer coordinates option, my finger registers as two,sometimes three. It makes it difficult to type, and just hard to use. Do i have a hardware issue or is it something I can easily fix?

Did you flash another ROM?
if stock: there is maybe moisture or dust, take apart as much as possible and hoover round the edges,If the touch screen is still not working, the tab is broken as the majority if touch screen phones and tabs cannot be calibrated
The tablet is still under warranty, so I don't want to dissemble. It had rooted stock OS on it, ICS. I flashed the stock rom back, and still have the issue. Did a Factory reset, and still have the issue. I am in the process of draining the battery to see if that helps. But I was hoping someone may have had this happen before, and can shed some light on my problem.
well, if you still got a warranty claim it then

Try using the touchscreen tune app (requires root).
This will allow you to modify screen sensitivity and test.
If you have the warranty..backup your data and claim a new one.

I don,'t think this app will work as this looks like a hardware issue after flashing another ROM, maybe you can check the all forum-searcher and check if anyone else has this issue too.
I'd suggest to send it back and claim a new tablet as well!

my matrix is getting really HOT

Hello matrix users i have big problem whit my phone. When i use it for a while its getting really freaking hot in the area of the buttons and the speaker its not the battery also the battery life is ok. so i think it's something hidden beneath the buttons... any ideas what my cause this? btw this begin after radio update i used some chinish radio but after few days i back the stock radio. i tested few other radios and roms but no changes.. my phone still get hot..
Please help meeeeeee
It's most probably soc or modem. Under the buttons there is not much that could heat up. Did you recently change your location? Try setting modem to 2g only.

Just a thought, but the point at which is starts heating up might help indicate what the problem is, that and logs (logcat and dmesg).
I know that mine has a major issue with draining/heating (hot enough to smell it) while using the GPS navigation, even with the official, unmodified Motorola GB ROM (haven't had the change to try it in ICS), and the only way around that I found was to download (cache) the maps. In your case, however, it's possible you may have damaged the modem. Just for kicks, I would try booting into recovery and let it idle for a few minutes to see if it gets hot. Another option is to select the boot option that bypasses the modem and see if that gets hot as well. Without logs, it's impossible to guess beyond what Krystian already told you as sometimes it's hard enough to figure it out even with logs.
AFAIK, GPS is a big energy spender and a big device heater for all devices out there. This is due to technical limitations of the GPS system and is not really avoidable.

Touchscreen ghosting

Hi guys!
I bought the Z3TC LTE and are very happy with the device but I experience kind of ghosting with the touch screen:
Moving my finger up and down on an scrollable page / app it starts missing or skipping a movement!
Is that a general problem or should I return the device?
I made an demonstration Video:
http://youtu.be/EUeAt1HMt-w
try a reboot.
is it only 1 app or is it happening on different apps?
Reproducible in every App! Reboot does not help!
If I find time I'm gonna try the same on an Z3TC in an local store..
hmmm thats strange....
glove mode is not on right?
If not, try a factory reset.
if that does not work, sounds like service.....
does this happen when you are charging the device? sometimes this is caused by a charger that doesn't supply sufficient current
Sent from my HTC One_M8 using XDA Free mobile app
I think I am facing the opposite of that. The screen is far too sensitive and sometimes takes a scroll as a touch. Happens everywhere on the device. I fear it's a hardware thing.

I had a similar problem for a couple of days.
The tablet would scroll up and down on web pages erratically and also when using the keyboard it would enter words independently.
The issue resolved itself after awhile so there is nothing I can suggest to fix it.

I had the same issue and end up got a replacement from vendor. They didn't do serious check and question me as usual. Then give me another one.

Mine works perfectly fine
