So, A5 has almost the same specifications as A8, and A8 still has Android 5.1 and not yet upgrade for 6.x. Is there going to be an update?
This is one of the best phones I've had (I have the Y813), it's with the latest May 19 FW version, but most of the the 3G network weakens by 1-2 bars or even fails and switches to Edge. This is my second A8 and it was the same with the previous phone. I live in a city with good reception.
I think this drains the battery faster, so my battery lasts only about half day.
I don't know if this is related to the firmware, but this didn't happen on the Blackview A5.
