Flash a FTF via flashtool and exclude data, if it still does it then it may be your hardware at this point

FTF can be generic, and of any country but spesificly for your device aka D6503
(some branded ones have a simlock thing)
Im not sure about screen protector, usualy if its realy thick but then the entire screen wouldent respond

Thanks a lot. Phone I have 6 days , three days ago I had this problem and last night. When the signal is weak I have a feeling that that creates problems. More seems to me that the software itself , because apps have lag, slow open apps. If happens again I'll see to record that and put on youtube . Thanks in any case , I'll try what you've suggested so I'll see how it stands phone .

[Q] Touchscreen Problem

I have a problem with a touchscreen. This can be seen that in the lower left corner of the screen, the phone detects a second touch. I put a screen shot of the presentation of how it looks in the test. This occurs on every rom 2.3 +, excluding Glsmt 2.1. When I plug the charger problem disappears. Whoever knows how to fix it?

Why do you NEED European firmware?

but the problem exists in Cyano Ace Port from BehradGH and currently there is no possibility to install fix

Hi
someone fix this bug?
My motorola atrix is a problem with the touch after I managed to release "root", you have to play lower down the keys to be hit from above, in addition to the menu buttons do not work, but half of it straight up works best, does anyone have any solution?
Perhaps a better bios reset, or a full format! hardware will be? or software?
Somebody help!

i think u got better chance if u ask in ur device specific forum
This problem is fixed in KPY, i have this one "GT-S5830_XEU_S5830XWKPY-S5830XEUKP1-S5830XWKPA-S5830XWKPY4" and problem is gone.
I have the same problem..
My phone registers random touches in the lower right area, approximately above the middle of the home and back button. I have Indian firmware S5830DDKQ5, and the problem started just after I upgraded to it by official Kies update. Before this, in Froyo, this never happened. I thought maybe it was a hardware problem in my phone or the screen protector was causing it, or maybe something broke due to some fall to the ground, but you have the same problem, originating from 2.3+ roms, so perhaps not. I have not tried any rom except the stock one.
icemanhi, you say it is fixed in XE/XW KPY but KPY would come before KQ5, wouldn't it? I'd like to not go to an older firmware, because we don't know what the changes between them are.

Even when the phone is kept undisturbed on a flat surface untouched it still happens...
icemanhi, you say it is fixed in XE/XW KPY but KPY would come before KQ5 and I don't want to put something other than the stock official firmware. I cannot just keep changing roms either, I don't have time for that..
Please if anyone has a fix then share it.

take your phone to samsung service center and tell them about this problem
But...
I can't make the problem show up on demand.. the people at the service center will say, show me what happens, but it's random, so I can't show it to them. Then they'll say, "the problem is not happening in front of us, so we can't do anything." Still, I'll ask, but would prefer a different solution. Thanks.

LWW Return doesn't always work.

Hey !
My rom is full stock .431 ICS version but the same problem happens on .587
The return button sometimes lags and doesnt work. After few spam clicks it starts to work again. The touchscreen in that place of the screen is working so it must be something else.
Any idea what to do? Or I have to send it on the guarantee.

If you have never rooted and most importantly unlocked boot loader then my advice Is that you should send it to service center asap..

It's a known problem, many people get this. Sometimes they "spam" the button to fix this or lock and unlock again or reboot. As far as I know there's no fix, yet....
Maybe really bring it to service if you never rooted and bootloader is locked...
On some LWW forum people told me that it also happens to people with GB and after they send it to service they just flash new rom and thats all. The guarantee is 2 years and I can do everything they will do there here at home , so better not to lose 2 weeks without a phone..
Some people also have problems like it with the right button (menu) . For me it's working fine.
Well thanks for info anyway. I'll keep with it for now. If it gets worse I'm sending it to service.
-1 point to Sony Ericsson for a bug on the whole model line
I also sometimes happens that problem flashing the tft try again or repair with PC Companion but can you solve the problem
I found the reason. Dirty screen on return/menu place...
After I cleaned it and made it dirty again its the same, so it's not a soft or hardware problem
Just keep the screen really clean

man i'm sorry , but you have bricked Screen !
Hi
What do you want to do?
If your screen is broken, you could "do" something via ADB, but not so much.
PERHAPS you could delete your lockscreen (you can do, search), make the device boot wisthout sim cadr (=no pin), install (adb install) something like airdroid or similar (i do not know such apps), launch it (inside ADB with "am" + something) and hope you can "use" your phone via PC.
Ok looks more like SCI-FI!

My friend has a Mini Pro with broken lcd , he broke it 6 months back but he still manages to use till now with out any problem....
try flashing custom kernel and a new ROM , If that doesnt help.... u have to go to customer care..
Re:all
thanks all, but i'm sure that lcd is fine (maybe), because, before that (suddenly restart) my phone is allready fine with all function normally (although my lcd is broken but touch function is normal). until restart happen, my phone was not start up again. in lcd i see blank, no logo and anything. just vibrate 2 times. in that condition i think, i can make a call for test but the warning from sim operator said that my phone was turn off.

for Publiuss, i hope you can give me tutorial how to controllling my phone via pc in condition my phone like now.
maybe use the usb cable to know that my phone (until flashing rom or kernel) was working or not, and if i can getting that, means, my phone trouble in lcd.
i will keep out for cust care if i can solving my trouble by self, because maybe if i have to go cust care they will charge me cost not much different with new buying this phone.

Well Man i say is not software problem. If you flash stock firms, custom roms and kernels you manipulate all the system if the phone dont turn on is a ardware problem. Search a tuto how to open you phone and see if dont have nothing wrong. The conection screen "flex".you see all ok buy a new screen on eBay. Try. After all that phone is very important for you.
Press thnks if I helped to your mind.
Sent from my SK17i using xda premium
actually i had the exact same (or similar) problem after 6 months of ownership.
1) broken screen, dropped phone several times, everything still works no trouble
2) random restarts
3) boot problems, restarts got more frequent
4) can no longer boot, only a lit black screen, no SE logo
Does that sound familiar?
I understand it could be a HW problem but the only thing I can think of is the digitaliser/screen. Try to replace that and see far you get, you can find a replacement cheap from ebay (they come free with tools) and also disassembly guides are on ifixit
please post your results!!
Mini Pro screen is really vulnerable, so even a little defect can cause further issues.
I had a Mini Pro which its screen cracked when I dropped it, it was fully functionable for weeks then one Friday touchscreen didn't response anymore.
I visited a technician and paid about 4,000 Philippine pesos to get it fixed.
Second defect happened after I came back to Korea, when I dropped it toward the wooden frame of my bed.
At first the screen had several purple horizontal lines, then soon it completely blacked out.
It still exists inside my drawer, and since I loved its keypad, I recently ordered $20 screen set in Aliexpress.
I have a question: Did you fix your device after writing this thread? Was the problem related only with the screen?

can not always hang up calls

Can not always hang up calls it disconncts the call and beep beep around 10 sec then hang up screen disapears, must also ask my screen has been come hypersensitve after i put a cheap screen shield and i have not removed the old one.
have someone else Experiencing the same issues.

try to repair your phone with PC Companion, do like if you want to update then it say your phone is already up to date, then on the same window you have the option to repair. Never had this problem with the phone, maybe a firmware bug. Repair wipe totally the internal memory, so think about make a backup if you need.

Just want to say that same thing is happening to me last few weeks with same phone. Thing is, it didn't worked worse and worse, but it just worked well one day, and the other day it was terrible, and it still works equally terrible. I never rooted or flashed my phone and never sleeped on it so I think that's not the problem.
Hope you can help us..

Same here
Hey, I'm having the same issue with my Xperia Neo (MT15i). :crying:
My phone is nearly 2 years old. I have used Gingerbread, then ICS, Jelly Bean (Rooted-Cyanagenmod). I had no issue with the touch screen earlier. Since the phone performs bit slow on advanced android versions I decided to install Gingerbread again to make it faster.
From the day I installed GB again, I'm having this issue.
Gotta swipe about 4 times to answer or reject a call. (Even I do press power button to off the screen, then power button again only then swipe works)
Swipe about 4 times to unlock the screen.
Try the pattern about 4 times.
I believe it's a software issue. If it's a hardware issue touch screen should not be working at all right? The thing is, it only malfunctions like that for the first 4~5 touches when the screen turned on. After that the whole touch screen works perfectly.
I was using my phone rooted for a long time without any issue. This started when I tried to flash gingerbread again in last month. I flashed another gingerbread tft, but the problem still remains.
Today I flashed the kernel to FusioN v5.5 and installed MIUI 5, still the issue is there...

i am totally confused bro what to do!!! on a very day i went to a hardware technicians shop to solve the problem!! they said it may be hardware problem but did not say surely!!!!!!! i am looking forward a kind help from any expert of this forum!!!!!!!!!!!!!!
I'm having the same.i have tried anything but still same issue.
Hello people!
I had the same problem when 2 of my friends tried to pull the phone vigorously! -_-
I had to swipe 4-5 to get it to respond and the screen would act weird for another couple of seconds! -_-
Tried Factory Reset etc but still no use!
So I took it to the service center and they said it could be the digitizer(screen) problem but not sure, and that it would cost 4k for that!
Fortunately I had another problem with the sound setting on my phone so I gave it back to them to solve that at least. They flashed the phone with latest ftf(some GB ftf at the time) and gave back the phone saying they couldn't solve the sound issue.
BUT to my surprise/luck my screen prob was fixed! And I dint pay them a single pie!
So I think y'all should try flashing the Stock ftf, preferably ICS 4.1.B.0.587 and its Kernel
Here is the link - http://forum.xda-developers.com/showthread.php?t=1952333
I hope it works for y'all! All the best!
P.S - I'm now running Super Jelly Bean 8.0 on SuperFusionNeoKK Kernel
