I have a 5 years old oppo phone and decide to use it as podcast device. A few odd thing about this phone: 1) My Google, IG accounts both sent me security alert about successful login attempt from from Thailand, Vietnam. I 100% sure I only created the IG from this phone once and have not used that password from anywhere else. IG Username / password was taken from this phone and attempt to be login from somewhere else. 2) I can't get the phone to disconnect from wifi. I put the phone on airplane mode, disable wifi, bt, etc. Manually change the wifi password to something else. it always successfully reconnected back after a few days with old password. There are logic in the phone can try very hard to state connected online. It remembers old password and successfully connect successfully with it after a few days. Only rename the wifi ap in my router seems to finally permanently disconnect it from the network. 3) I have let the phone back online and created Google account that is 100% unique to this phone. Love know how long would it take for the login attempt for that G account from Thailand/Vietnam start to show up.
