"Android (operating system): How can I solve ""Unfortunately System UI has stopped"" and ""Unfortunately Gallery has stopped"" messages on a Samsung S4 after I upgraded from Android 4.4.2 to 5.0.1?"
If I factory reset my Nexus 4 will the Android 5.0.1 be downgraded to 4.4.2? Will I again get OTA for Android 5.0.1?
