My iPad mini is slow opening apps and it’s getting frustrating. When purchased it wasn’t slow rather it was fast. This iPad mini i think is the second model that came out, its model ME276E/A. When I googled it it says it’s an iPad min 2 series.
How can I make this device return to be fast? (Note, from 16gb capacity, it has 3gb available, it’s version IOS 11.2.5, 16 apps, 90 songs, 1 photo)
