Android USB Tethering Drops and Data Usage Crashes, try Reset

20160314 Android USB Tethering Drops and Data Usage Crashes, try Reset

The USB Tethering between my Asus Wireless Router RT-AC51U and Sony Xperia C3 which is runningAndroid 5.1.1 drops about every 30 minutes. And I also found the “Data Usage” in Settings always crashes every time I launch it after experiencing the unusual drop. Therefore, I assume they are related.

It’s not my data connection has been dropped, it is the connection between RT-AC51U and C3. I am sure because if I manually disable data connection on C3USB Tethering is still enabled. Therefore, I assume the problem is about USB Tethering rather than data connection on C3.

Interesting, I cannot check the “Data Usage” in Settings after data connection begins to drop frequently. It always crashes the Settings App. Reboot my C3 doesn’t help. Wonder if someone has hacked to my device and block me from checking “Data Usage” to detect uncommon internet access.

To find out what’s going on, I uninstall every download apps and disable build-in app one by one. Strangely, C3 reboots itself every time after uninstalling or disabling an app and I have never being about to check my “Data Usage“.

Eventually, I decide to reset. Guess what, theUSB Tethering never drops again within 5 days.

I cannot solve my problem and seems reset is the only work around available.
