screen looses touch when looking for data. hard restart needed.

[roels]

after 7 months of no problems with my phone he suddenly started to be unresponsive to touch when i am in an area with bad connection (woods, cellars, elevator, big concrete building). If this happens i have to do a hard restart after which the phone works as before. sometimes this doesnt happen for a week and other days i have to reboot my phone 5+ times. this is becoming increesingly enoying. i also noticed this doesnt happen when my mobile data is switched off, so i suppose that here lies the problem. he s looking for a connection, doesnt find it and the screen stops working (the button on the side still works and i keep on receiving messages, calls,...)

anyone with the same problem?

also, my update to lollipop seems not to be available yet (belgium), is this possible? (i checked it both on the phone and with pc companion)

any help would be much apreciated!

It'll be wise to reinstall the latest update and check again 

PC Companion (PCC)

Bridge (for Mac)

i did a repair, problem not solved

after i reinstalled everything and the problem still is not solved.

so strange since it has to be something with the software (it works again after a reboot)...

This could be hardware, as it only happens when using data functions. I would suggest that you contact Sony Mobile Customer Care within your region, they should be able to help.
