2 annoying problems with Nexus 7 2013 - no fix for neraly 4 months

1st: Ever since I bought Nexus 7 2013 (in last September) I was never able to REWIND or SKIP a buffered stream - whenever I adjust the slider it goes back to the beginning of the buffered stream. Same versions works fine on not so popular HUAWEI P1 with 4.0.3 - I can rewind/advanced any time I want.

2nd - For the lat 2 months (at least), on the Nexus with stock latest update, the app force closes 50 times a DAY !!! So annoying. I have an older version from summer 2013 that DOES NOT force closes but it lacks uber stations (I think its 3.0.2 or something).

PLEASE FIX THOSE ISSUES. I have sents hundreds of reports for the force closure.
