This is not a Neutron's issue but PlayBook's. The same problem is on BB10 OS. If PlayBook/BB10 OS is working for several days it can not handle well the background playback of audio. The problem is known by audio team of BB and may be solved in BB10 10.2 but not in PlayBook as BlackBerry decided to discontinue its support. Glitches and Sluttering are happening inside the OS audio layer.
> plays Music as if it was a Retro Gramophone Record Player
It is difficult to comment actually
If you could describe in more details it would be great. If you just installed Neutron, did not make any modifications and simply started playback you will get fully correct decoded audio. Everything depends on the source music files you have.> it should have been designed BETTER
The work never stops, users who are for a long time with Neutron are aware of that fact
I am sorry that you did not like UI and layout but you had many screenshots before purchasing...Refunds are handled only by BlackBerry, unlike on Google Play where developers are able to make refunds, on BlackBerry we can't do anything about. Please forward refund request to BlackBerry World customer support.
