I updated to PRD1.2 (without reflashing)all was smoth, till I upgraded kernel from 34 to 37. Since then my UI is laggy. I'm using default profile. On ideal is working perfect, but I installed it to have some extra features, and I don't want to run overclocked phone when not needed. I was trying to deinstall kernel before PRD1.2 with menu shortcut. It failed but i did OTA update and then updated kernel via app manager(there were new version) after it i tryed : apt-get install --reinstall kernel-power kernel-power-modules kernel-power-flasher but no use. The most significant slowdowns is when I'm entering to menu. Most times I can't see animation or can see just few frames from it. How deinstall shortcut works? Can you have smooth interface on default settings?
