Keith has three Android phones that are all acting up. They take forever to read and boot up. Leo says that Keith can do a complete reset and restore, but he can also do a deeper reset, which will wipe everything including the cache. His Transformer may also need a new SSD, as they do wear out.
It may also be that it needs TRIM with an Android update. Keith should press and hold on/off and the volume up button at the same time. It'll get him into the Admin menu so he can reset it completely. The bottom line, though, is that the devices are all pretty old now and they could just be wearing out.
