Hey Thomas,
Just wanted to ask a couple more questions before I write this issue up as a bug. What Android build are you using (Android, Android ACT, Android ETC1…) ? Also, have you tried to build in 4.3? There were many bugs fixed between 4.2.1 and 4.3, so i just wanted to check and see if maybe that was solved. Any additional information you could provide would be greatly appreciated.
Thanks for your patience and have a great day!
