I'm looking into a new device there a few 7" tablets at round £50-60. So that may be an option.
Whats bothering me though, is that my android is 4.3 but the wife's is 4.1.2, the whole phone is a real clunker. Mine is an S3, so its old but still somewhat decent. I just don't get how hers works and mine doesn't. And that worries me for getting another device, don't want to find that it doesn't work either.
Edit: Turns out hers is 4.4.2, got it confused with the tablet. It really is struggling with running the app.
