It has been repaired a few months ago, for a 3G signal problem after I reset the device.
Motherboard and screen has been replaced.
After replacing the motherboard and screen I still have problems with my One S
3G and 2G internet is sometimes working but most of the times not working
I have to reset my telephone many times hoping my 2G or 2G Internet works
Or I can wait 10 minutes and hope it will connect
My 2G and 3G signal is pefect, but my Internet is not working
To avoid warranty problems I still use the jellybean firmware.
Is rooting and flashing the firmware an option to solve this Internet problems, or do I have to send it in for repair
