M7 random and long time vibrations, when pressing the back cover - One (M7) Q&A, Help & Troubleshooting

Hello,
My phone vibrate continuously in my pocket, jacket, when I talk and is near my ear, and everytime I press the top of the screen. In some cases the phone keep vibrating for two minutes without stopping, even I restart or close them. Seems like a pocket detection is always active and can't be interrupted, but I think is a hardware problem. After press the screen again and again, the phone stop vibrating, for some seconds or minutes. I discovered today that pushing with my fingers the back case (2-3 cm around the camera), the phone begin to vibrate. So, pushing the display in the same zone, will generate the same vibration. Probably it's a harware problem in this zone? Can be expensive to repair? In my country (Romania) the service must send the phone in Poland, the headquarter for repairs.

I recived today a reply from a local forum:
"your vibra module is wrong mounted, and touch the black cable (negative pole " - " , cable that was partially stripped. Must to open the case and isolate this cable"
Maybe this fix will be good for others users with the same problem.

System-volum bar goes up and down by itself

Hi,
I have a "little" problem which is very annoying...the volum bar goes up and down by itself, and this happens very often.

(Random picture from google)
Typing a message (or doing anything else on the phone) takes a very long time because it keeps popping up all the time. I upgraded the ROM, but that didn't work either....it seems to use a lot of battery when this happens too Battery can be dead after a day or less...and that's when I haven't even used it at all.
I have no idea why this started to happen...I hadn't done any changes on the phone before that. It doesn't seem to be anything wrong with the volume buttons on the side either so it must be a software problem.
Any tips are greatly appreciated
I believe we have the same issue: http://forum.xda-developers.com/showthread.php?p=4081584#post4081584
This started happening yesterday for me.
yeah we have the same bug :/ atleast it's nice to see that I'm not the only one with this problem...hopefully someone will come up with a solution to fix this problem....It's driving me crazy
This happened to me after the phone got a little wet. It disappeared after a few days tho.
any chance its the auto change volume of the apointments calander
that mute the sound when u are in a meeting ?

[SOLVED] Suddenly my Xperia T has no signal

From yesterday on my Xperia T doesn't have any signal, I cannot search a Network neither. I don't know why or how happened, just did.
I clean-flashed the 4.3 Stock Rom with Flashtool but it doesn't work. I'm going to try to switch SIMs with my girlfriend so I can see wether it's a phone or SIMcard problem. Any hints about this? Never happened before
Well, it's my phone's problem, my SIM has signal in my gf's phone but her SIM doesn't have signal in mine
I fixed it.
To anyone else having the same problem:
1. Shutdown the phone.
2. Disassemble the phone. There are plenty of tutorials if you don't know how.
2. Find this connector and unplug it.

3. After a few seconds, plug it back again (when you do, you should hear a 'click' sound)
4. Reassemble the phone.
That should work, at least did work for me. This is the second hardware problem I had (the first one was the battery not charging offline issue) and both of them were just fixed by detaching and plug in back their respective connectors. If I would have sent this to Sony i'm sure they would have asked me to pay a lot of money for repairing it.

[HELP]What is this cable for? Possible sudden death fix.

TOO LONG, DIDN'T READ: What is cable for? Where is it leading to? The phone doesn't work at all when I disconnect it. But as I press it, or reconnent when pressing doesn't do the trick, the phone boots and act like it used to.

Backstory:
So I dropped my phone once on the floor, perfectly flat on the screen.
Since then it would randomly shut off, indicating a dead battery (3 red LED signals) and do nothing. I managed to charge it after an entire night and a morning for 3 times, but then it died completely.
I decided to open the phone up, and after a month of playing around with it, I came to 2 defects.
The vibrator motor would constantly buzz, whether the phone was on or off, as long as the battery was charged.
When I pressed the motherboard on a certain place, namely a flat cable connector, suddenly the red light would show up, go back to very dim red, and suddenly the phone booted in "charging-mode".
So my phone was charging, and it worked completely fine, aside from the vibration motor ofcourse, which I disconnected.

I plugged it in 12V5A power in house for several hours to fix itself but it still stuck on white screen.
to be Clarify- white screen is also on boot logo and on recovery mod
does anyone knows how to fix it?
thanks in advance.
after openning the device by removing one screw at the back and two screws at the sides, then you remove the DVD drive by removing 4 screws.
then 2 screws at each side to remove the screen and you need to disconnect and reconect the big white cable from the board to the screen.
this works for me

Problem with my head units, not work

Hello
I have a problem with my head units.
The device worked properly only two weeks.
Now the device works only a few minutes after switching on. After a while the picture will freeze and the Artifact will appear. More and more Artifact until the display turns into one color (white or purple on the pictures). Then the display turns off completely. The radio can still be heard from the speakers, the touch screen and touch buttons are not working.
When I press the reset button, it resets the device but it will not turn on.
It will turn on after 2-3 hours of parking
Has anyone had a similar problem and can I give you a hint as to how to fix it?
Regards and sorry for my poor English
