Phone: Xiaomi M2S 16GB MIUI 3.7.5 weekly build multilanguage (dutch selected) I noticed when mobile data and Wifi are both enabled frequent random switching between Wifi and mobile data occurs (independent of power (saving) mode). Wifi or mobile data seem to work correct when seperately enabled. I watched more closely and observed wifi instability so the switching is explained ! Why wifi is instable is another question. It is not dependent on the AP because i observed this on more then one. Any suggestion would be appreciated. Should i do a system wipe/factory default first ? Thx.
