  1. was using clean master for a while and notice that i couldnt receive mms….deleted clean master and all was good…..will try power clean as

  2. We are getting our android remotely turnedon, and unwanted apps downloading onto the phone. We have cleanmaster, and it does clean the phone, but it DOESN’T prevent the apps downloading, and sometimes installing. Sometimes installing, and then uninstalling is the only way to get rid of them. This is using LOADS of battery, and where the battery used to need charging every three days or so, it’s now two to three times a day. Fotunately there is no mobile data set, and we only use the house wi-fi, otherwise this would be costing a small fortune in overusage. Is ther any way, other than turning off the house router (not practical as ther are two PC’s in daily use) to stop this PLEASE!!!
