Many a times the System UI is not responding, will need to restart the system. On the performance it is little slower in processing. While charging the mobile, could see a lot of heat dissipation. The basic features like voice recorder, theme changer, silent mode (ringer), Gallery apps are not available, which is more disappointing.
My system UI crashes 2-3 times a day as well. Along with my Gmail, YouTube, Photos apps all crash too. The phone consistently gets hung up when multitasking. I've been trying to wipe the system cache, but can't figure out how to enter recovery mode. Is there anything else I can try to fix this issue of the system UI crashing?
