Xperia SP screen problem

[ugurkaya]

Dears firstly I have to say I'm very sick and tired of small but annoying bugs of Xperias.

My Xperia SP which is bought about a month ago, has some annoying display problem which is, when I press power button to turn the screen off, sometimes (actually frequently) the screen illumination(the background illumination of display, not the illumination bar) lights up but display does not wake up. Those who know how TFT screen works should understand what I mean.

Has any of you faced this problem?

Okay, this is really disappointing from Sony! I barely had the fone in my hand for a few minutes after removing from a new sealed pack, that I noticed the top half of the screen was not working. This can be expected from a cheap chinese fone but not Sony. Not a great start with the fone! Absoluely gutted.:smileyangry:

HOLA A TODOS!!: 

Soy de Lima Peru y esto es un problema de hadrware, segun un comentario de un personal de sony.

RESPUESTA DE SONY 

Aqui pueden ver que el problema viene desde la calibracion de la pantalla tactil, algunos celular vienen con la opcion para poder calibrarlos en si mismo, el xperia SP lamentablemente NO!!, y solo podemos esperar por la version android 4.3 o 4.4 kit kat a ver si estos problemas tienen solucion, en todo caso, desasernos de nuestro xperia SP o exijir un reembolso por parte de sony o empresa intermediaria, espero esto solucione preguntas a muchos, saludos a todos!!!

HELLO EVERYONE!:

I'm fromLimaPeruandthis is aproblemhadrware, according to acomment from astaffsony.
 
RESPONSE FROM SONY
 
Here you can see that the problem comes from the calibration of the touch screen, some phone come with the option to calibrate itself, xperia SP unfortunately NO!, And we can only wait for the upgrade android 4.3 or 4.4 kit kat to see if these problems have solution, in any case, our xperia desasernos exijir SP or a refund from sony or intermediary company, I hope this will solve many questions, greetings to all!  

add this:

A few days ago my xperia SP testing , I found the surprise that when I put it to charge current or lapto connected to 5 volts , this happens , the screen does not respond randomly .

Or when under the flap where the activities are as new messages or missed calls, and leave half and I got my finger but still varies notifications bar and moves alone, or I can also tell when I move screens side to side and always contact occasionally is lost, BUT ONLY wHEN LOADING tHE BATTERY.

I believe this may occur by a resistance is clashing with the cable to positive because the current flowing in the internal battery contacts with capacitive screen ,

SOMEONE ELSE HAPPENS TO THIS? . thanks
