Using the TF2 Sprint here.
The ringtone thing is workable, but really if you can, please fix the issue with not setting it from settings...Why?
Coupled with this bug its downright annoying:
The home button on the phone itself won't go back to home. (consistently) It seems to like to bug out the most in Touch Flo.
You hit it, the screen flashes on the indicator bar, and thats it.
You can use the back arrow only.
Youtube is not working on this either.
File Youtube cannot be opened. Either it is not signed with a trusted cert, etc.
Txt msg sound does not work: "Excuse me boss..." (This is made worse by the problem with the sounds/notifications tab not working) If you can't fix the sounds tab, then its going to be unpossible to change these sounds ever in TF2.
There's also a bit of slowness, I assume due to pagepool?
Those are my biggest issues so far. Otherwise, its pretty good.
edit: tried sprint tv too, doesn't work.
