screen blank during/ after phone call, than freezes

Fri, 30 Dec 2011 15:36:29 GMT

ya as stated as the title, some times when i called, or received a call, my screen will turn blank and after the call, the screen remains blank and unresponsive. only way to get it to work again is to unplug the batt or to connect to a charger...

now on android 2.3.4

is it a software or a hardware prob??

pls advice, thanks much 😃

you can cheeck it by

dialing *#*#7378423#*#*

then select service test , proximity switch

move your hands over it and see , it should make a sound in the test..

mark correct and helpful answers..

Ya...it's the sensor, it stays on constantly, once in a while it will be back to normal (prox off when uncovered, on when covered)

that is not right...

you mean without your hand over it , it shows on..??

you should get it checked with a service centre nearby..

Great answer! And very helpful to know this string to verify hardware problems!

However, in my case it seems the display protection irritated the sensor. Once I removed it, everything worked perfectly!
