My phone started having bootloop issues since last November update. WiFi getting automatically disconnected and phone is restarting, when WiFi and Bluetooth are on. Seems to be a WiFi driver issue. 

I'm from India and my phone is brought from Sweden(Exynos variant). I could see people from UK complaining mostly. I think only exynos variant is having this issue. My friends residing in India having snapdragon processor aren't facing this issue.

When I contacted Samsung India. they are asking me to consult Samsung Europe as it is bought in Sweden. Buying such an expensive phone and it becoming unusable just because of a software update. Samsung should do something on their part, at least provide a proper update or get the phones repaired. This is becoming a headache to all the users due to faulty software.
