I have a quite annoying problem with this wonderful phone. From time to time my phone just randomly disconnects from wifi. After 5-10 seconds it reconnects, but it's not how it should work. Also I listen music using wireless earbuds sometimes and yet again, phone just disconnects from them in the middle of a song. After that, it also reconnects. But there is no specific interval, in which phone regularly disconnects from Wifi and Bluetooth.
