As you know, HTC has stopped major updates for the One mini, One mini 2 as well as One M7, and users can’t get Android 5.1 in the next future. We don’t know what’s the reason why the company won’t release any future update for these devices, and maybe due to the hardware.
Not like HTC, Motorola has announced new software updates for both Moto E 1st and 2nd gen, and bring the device to latest version, Android 5.1 Lollipop (Android 5.1.1 for Moto E 1st gen). The Android 5.1 comes with massive changes: notifications on the lock screen, privacy and priority notifications, customize notifications and a lot more features.
If you haven’t received any notification about this update yet, then please go to Settings > About Phone > System Updates to check if it’s there. You have already updated your smartphone ? Tell us if there is any different and new features.
