Light sensor and touchscreen

[jwseegers1]

I just a performance test (*#*#7378423#*#*) and the lightsensor values stay on 0% In clear daylight and in the dark. I presume the values should react immediately.

I'm also not happy with the touchscreen. Sometimes I have to tap many times on a button before it reacts. Is this normal with Sony phones? A friend of mine has a Samsung and some of the apps are the same as mine and he does not have this problem. Anyone else with these problems and is there a solution?

Yes, I check it now and you right, the sensor value stay on 0%. This is another bug of shet JB update.

Is the maybe anyone from the Sony Xperia epert team who has the decency to at least react on my problem? This is the second time I posted but no solution was given

do you have anything covering the sensors? have you apply an extra screen/film protector? have you tested with a flashlight?

[jwseegers1]

Thank you for your quick reply. I don't use a screen/film protector. Nothing is covering the light sensor. I tested it in the dark and with a bright flashlight. The value stays on 0. Any Idea's?

that's odd, how about repairing your phone with either PCC or SUS > do not install any app, uninstall mcafee > test again with service menu

I did the re install via Companion, uninstalled Mc Afee but the value of the light sensor is still zero.

Now what? btw I am not doing a re install again. This is the 3d time I did a re install. I'm still busy with re installing app, setting etc. It seems it's the only answer the Sony "experts" can give. That is, if they react in the first place at all. (Not you uliwooly, I read a lot of helpful answers from you)

that's quite odd, I have couple more suggestions

1) take it to a sony repair center

or

2) create a backup of your current firmware > downgrade > test the light sensor > if it doesn't work then you will know for sure that its a hardware issue > flashback and take your phone to a sony repair center.

This seems to be a problem with the service menu and not the sensor. I tested this here and in the service menu it stays at 0. The sensor does however work, the phone adjusts brightness of the display when i tilt it towards a lamp.

Regarding the touch display i recommend that you contact a service location or local Sony Xperia support.
