Have the phone from Amazon get quickly and am pleasantly surprised by the processing and the accessories. After commissioning was carried out by me to check for viruses, Trojan horses and PUP with Avast. As suspected, the installed system software includes a Trojan (included in MUI.apk). An alternative Launcher needs to get rid of the trojan out the unwanted software are installed (eg Nova) since conceals the preinstalled launcher. After the change of the launcher can be via the mobile vRoot rooten (NOTE: this we installed the next Chinese Trojans, this we remove in the following steps). If the phone rooted installed you look at the app superuser of Chainfire and will update the binaries. Once this is done you can download from the App Store one to uninstall system applications and remove the apps MUI.apk and the Chinese Superuser app (Chinese Zeichen.apk, or when using RootGenius instead vRoot KingUser.apk). After that you have a clean phone with great performance gerootetes to Top! Who should the above steps not trust keep better by another device out, hence only 3 star although the unit price / performance default actually deserves 5.
