1. GPU forced to render the UI, well everyone have different definition about smoothness.
2. idk what happen to you, its working on me both. main camera workin by default, front camera fixed by add media_profile.xml to /system/etc/
3. yes, i notice the battery problem.
thank the feedback, Racht
Did you try installing the new Adreno driver for the Gfx ?
It might fix a lot of issues ..
The camera : I did not apply front camera fix, it might work, but main camera when started shows image, and seems working, but pressing anything causes alert "Camera stopped responding, will close"
About battery, I think the issue is with kernel .. I am normally using miui based 2.3.7 with uv/oc, set to :
Screen on : 460Mhz-1.6Ghz
Screen off : 122-245Mhz
With these settings (SetCPU) I am getting 24 hours with WIFI or 72Hrs without WIFI.
