For some reason i feel like the previous firmware was more stable than this new one (PR1.2), i face following issues:
1. Cannot find Bluetooth devices anymore, it just keep searching.
2. Menu > Settings > My Nokia causes "Internal Error; application closed" !
3. Sometimes, when it's charging, the orange LED won't work.
4. Startup is slow. PR1.1.1 was faster

I updated via NSU.
