I am using this phone Huawei Honor Holly for a month or more , but every time i browse internet on this phone, i get an alert m.appasliu.com says " your phone is too slow and need to clear cache, delete junk files, free up ram and storage space" and It doesn't allow me further unless i install the suggested app which is mostly du speed booster or some other. What is frustrating is i keep getting this alert even after installing it and i can't browse due to this. Someone pleasse help me, how can i blow these alerts. In security settings i disabled instaling apps on thier own
