I'm on an unrooted Verizon Galaxy Note 4 running Android 4.4.4.
I have not accepted the Lollipop preparation updates, because Android 5.0 on Snapdragon processors is known to have poor performance when using Gear VR.
In the last week I've noticed that USB debugging is grayed-out, even when plugged into a Windows 7 computer. I have tried using different USB cables and different computers.
I need to be able to use EasyTether, which requires USB debugging.
I have tried rebooting to Safe Mode, but this didn't help. USB debugging is still disabled.
- Is it because I have deferred the OTA updates? How can I restore USB debugging without accepting the OTA update?
- I've been using Samsung KNOX for months now and it hasn't interfered with USB debugging. Has something changed with Samsung KNOX?
