After allowing the use of my android 8.1 hotspot for people that I know steal identities and financial information I notice phone configuration changes. Such as USB configuration being set to MTP or PTP when it was originally set to CHARGING. Unless I clear data for MTP HOST I cannot reset it to CHARGING. Also I notice that my phone will not charge at fast rates. Lastly, after allowing the use of my hotspot I believe my cell connects to rouge base stations and WIFI calling turns on and the version number of some applications change. I also see that applications without names are connecting to the internet. The only way I have been able to return my phone back to its normal function is by doing a factory reset and reinstalling my apps. I am certain my phone is being attacked through its hotspot. I also notice all these same issues after connecting to some WiFi hotspolts. How are my hotspot and WiFi connection being attacked? How to I allow the use of my hotspot and prevent the attacks? Howdo I safely use WiFi hotspots.
