NEXUS4 is a struggle after updating 4.4. . . . (Yes)

Software incompatibility is not a system problem, but that software vendors can't keep up with the upgrade of mobile phone systems or software operators have never considered upgrading. I started to brush from Android 2.3.6, and I have already found the finder's fault. Others should be the problem of system optimization. I believe there will be an upgraded version soon. Anyway, the new system is almost optimized when it is used, and it is easy.

If you want to brush back to 4.3, just find the next button to brush back the native system post in the 4 sub-sections of the machine front forum and brush back to 4.3 directly. Using factory settings will not reduce you to version 4.3.

I hope the above can help you.
