Hello I bought Meizu m6 note the seller changed the firmware version from chinese to Flyme 6.1.4.1G firmware. I did a factory restore I still have Flyme 6.1.4.1G thats okay, but i cannot install or uninstall any app (.apk). When I try to install any .apk I tap the Install button the installation closes. Same happens when I want to uninstall any app trough Settings -> Applications, when I tap uninstall the window closes and nothing happens. Could someone please help me with this problem? Thank you very much in advance for any help.
