[Q] Xperia T sceen unresponsive after update

Hi everybody,
I am experiencing a problem on my xperia T since the 4.3 update. Everytime I turn off screen, when I turn it back on screen is not responding. Phone is working fine, people can call me, all the buttons work (volume up and down, power off, camera) but screen is not repsonding to the touch. The only way to solve it is to turn it off ( power off button + volume up ) and then when i turn it back on it works normaly untill I turn off screen. Sometimes i can turn it back on and it would work, but in 90% of the cases it wont. I had no trouble until i updated to this usless 4.3 update. Anyone got solution?

[Q] N7000 stuck on welcome screen

A minute amount of water probably entered my N7000 when i got stuck in the rains, realizing that i switched it off and removed the battery. After a while i switched on the phone but it got stuck on the lock screen. after trying to dry the phone off for 2 days, i tried again but the phone would still get stuck on the lock screen. So i installed a stock ROM through ODIN. Now the phone is stuck on the samsung welcome screen with the "Choose Language" option. There is no response on touching the screen but there is haptic feedback on touching the menu and back keys. On pressing the power button, the phone goes into standy by once, but the second time pressing the power button has no effect. Any advice on what could be the problem and how could i rectify it? Is it a motherboard problem or could it be a problem with the touch screen?

[Q] Couldn't turn on the screen

Sometimes, the screen couldn't be turned on even if I press the power button, it seemed to be dead, but if I long press the power button, the screen turned on, and the menu of restart and power displayed, I selected to restart the gear, and then all will be OK. It had happened 3 times, I wonder if it is a software bug or hardware problem.

[Q] I9305 weird problem

Hi guys,
I hope you're all well.
I recently opened up my i9305 to remove a buggy power button whilst at it I was looking at the vibration motor. I reassembled it, placed it on charge. And it didn't respond instantly as usual, after a few minutes the red led light turns on but nothing else? What's weird is that when I press the home button the red led light will disappear for a few moments and then reappear. There's no way I can turn it on because I've got no power button, no splash screen comes up whilst charging.
Does anybody know what's going on? I'd appreciate any help
