Here on the forums they always start up a dedicated thread whenever something rolls out to keep all complaints and bug reports in one place. Posting there will make it much more likely that your issue will be noticed and addressed. Good luck!
As nicodeux and imnvs mentioned above, reports for mobile issues are best shared in the pinned thread in this section. I'm going to lock this thread, if you have additional details to share about these issues, or see any other issues on Android, please share them in that thread!
