One bug: If I switch on airplane mode and later I switch on the wifi (so my Note 4 works like a little Nexus 7), and finally I restart the Note 4, airplane mode keeps on, but the wifi is off. This didn't happen in the stock rom.
Although using "ALL IN ONE Version 1.03 * Fixed Knox removal & Ram fixes included", TWRP, while flashing, shows "version 1.02". Is it just because the info the screen shows wasn't updated or perhaps the link to the downloadable file is wrong?
It happens to me too. At first, I thought it was a new feature of the Note to save battery or something like that, but now I see perhaps is a bug, and a common one.
