Not so far, but this one is currently not much more than the default setup. The only thing I added was the Opera Tablet Browser, since the other offered apps required a google account and wireless access to the google store.
It plays mp4 vids by default, so it’s pretty much loafing along for the most part. Not much stress to cause a screenfreeze.
Cool! and thank you, better yet my Grandkids thank you! They got a great deal right now buy five and get a sixth one for free!! That’s means I have an extra just in case there is a issue with one! and then if not I have something to play with myself!
