Samsung Galaxy Feel cannot find any Wifi access points My Samsung Galaxy Feel (running on Android 8.0) cannot find any Wifi access points after turning on the Wifi.

Other mobile phones (iPhone, Xiaomi, Huawei) and computers can find more than three access points.

I've already tried factory reset.

How to fix this issue?
Try reinstaling system completely. Sometimes this helps. 
It is pretty hard to find firmware for samsungs now but i can give you app for this later, then just run odin. If you need support contact me.
