Even “Wi-Fi Hospot timeout” is set to [Never], when tethering & portable hotspot is ON and other device such as laptop is connected for a while (5-15 minutes), the other device will automatically disconnect and reconnect again. This happens from time to time.
Steps to replicate:
- Turn on [Hotspot] in Quick Settings of the status bar.
- Get other device to connect to the mobile hotspot.
- Try surfing a few webpages with the other device connected to the hotspot for about 5-15 minutes.
- The other device automatically disconnect and reconnect to the mobile hotspot again.
