Does it happen often ? When you cannot receive an incoming call can you emit an outgoing call ? When you cannot receive an incoming call, wake-up your phone and call it, does it work ? On the OP3, I had to modify the wake lock time otherwise the phone was not able to wake from a deep sleep : https://github.com/Halium/android_hardware_ril/commit/104191acb7cf431a92740efb3465d40b2cddcfe1

@AppLee That's why i ask him what uT version he has, because it's no longer in OTA13 as far as i know.

@Simon-jones managed to adb into the shell and used nano to quote out the mac address line. It worked. Thanks

I have a normal Xperia X and had the same issue and wiping partitions via TWRP does fix this issue
