Hi,

I have updated to Android 6 and both my network antennas are mostly off and turning on and off by them selves time to time... it even looks like they are fighting to turn on the antennas but then in the end they are forced to swith off by them selves every time they manage to get antenna.... I had to go back to Android 5.1... I hope that there will be an update for this.
Thanks.

Hi,

I have tried to update by OTA. Tried the Flash tool also by just "Downloading" to the phone and even after did a "Flash and download" ( which erased my IMEI from the flash but I managed to flash it back).
Conclusion: none of the attempts worked a 100% and still my sim card antennas were struggling to switch on.
Both sim card antenna swithes were always going on and off... I will stick with Android version 5.1 and wait for some other update.

I tried one more time and I see and think that this is an issue due to the APN which is blank... the network operators cannot connect due to not having any APN setting? How o fix this?
