Bluetooth turns off on LG G Flex 2

[ZionVb]

Hi

I have an LG G Flex 2, it runs on android 5.1.1 (latest version for this phone).
I use my bluetooth almost the whole day for my smartwatch (Ticwatch 2) or bluetooth speaker (phillips bt3600), but my bluetooth turns off automaticly almost every 15 minutes and it turns back on like half a second later.
But all the connections are lost then so this is very annoying.

Anyone has a solution for this or has the same problem?

Welcome to Android Central! Any power-saving modes turned on? Also, wi-fi can sometimes interfere with Bluetooth if you're on the 2.4 GHz frequency -- does this happen if you turn off wi-fi?
