Does Rocket work with the Viper4? I don't care for the UI on Neutron and would like to replace it. Any other ideas will be greatly appreciated.
Try (and buy) neutron. If you customize it JUST right, then it should come surprisingly close to the FiiO stock app levels of quality, but with extra juice!
Sadly, that's correct. So you currently have two choices:
1) Use a player that works.
2) Use the FiiO music app to give you very fractionally better SQ, and learn to live with random stops, crashes, failure to play when hidden system files are present, unreliable gapless playback, volume jump 10 s after plugging in your headphones, buggy scrubbing controls, buggy track name/number display and buggy track-time display.
P.S. IMHO, all the above "features" of the FiiO music app are bugs.
It's funny. I've rarely had random stops with the stock app. I DID however, have stops with Neutron due to the fact that I used a trial version, I bought the app, then use greenify to disable EVERYTHING that isn't related to playback. Yes, even the google play services, for some reason, THAT gets in the way.
If you buy neutron then just connect to the internet for about 30 seconds and you should be good. Since it will give you a re-confirmation screen to ensure you bought it.
On the other hand, I have had touch screen problems with it, I type things on the keyboard, and it gets an entirely DIFFERENT key. It's really frustrating, even in the stock FiiO app.
Then to make matters worse, sometimes the screen stops responding entirely and I have to hard reset it, really rustles my jimmies.
Never had faulty scrubbing controls, whatever those are, or track name/number/time display bugs, then again, each FiiO player has different bugs to begin with.
This player has a very diverse set of bugs. Fortunately, I haven't had it as bad as others, not to say my issues don't irritate me.
I don't know about the volume jump either, then again, maybe it's my amp. I'm using AM2 so maybe that has something to do with it.
I should update my review once more, there is lots of info I have yet to input.
Try updating if you haven't, or try ONE system format, something I'm about to do soon. I can't be assed yet.
Good luck on your player!
