The biggest issue is the lag. I get a lag on almost everything I do on this PoS, from a second or two to 10-15 seconds. I'll be typing a text and it will suddenly freeze. I'll push the key again because I think it didn't work. Still nothing. I push it again and suddenly I'll have four or five letters pop up. Or it will freeze when changing pages. I have an excellent calculator app that is almost unusable because there is a two second delay on every number entered. I have deleted many apps to try to free up more RAM but it doesn't help. Oh, and the Bluetooth is very intermittent and unreliable.
