Doplhin Browser has been more reliable than Chrome for me, but that's my opinion.
I've been using that on my previous, really old Android phone that doesn't support Chrome.
I'll try using Chrome for a while and switch to it if I experience too many reliability issues.
Spotify
I only have Spotify Unlimited, so that's.. yeah.
Youtube
Isn't this a default app?
App Garden
But of course.
Dropbox
Drive
I don't use cloud storage much (read: ever).
Flow Free
Temple Run
They both seem like pretty interesting games, I'll try them out.
