The AT&T Samsung Galaxy Note 4 currently has temp root, but no permanent root. I am not 100% sure I understand the difference.
From what I gather, temp root is lost if the phone is rebooted in a typical fashion:
- Battery drains to the point the phone shuts off
- Pull the battery, let the electricity discharge, put the battery back in, and boot the phone normally
- Tell the phone to reboot (for example by holding the power button and using that menu)
However, I remember reading (sorry lost the links) that a "soft" reboot will not force you to lose root. I'm not clear on what a soft reboot is. The description I read said something about the software rebooting but not the kernal. Finding information on this is troublesome since the terms "reboot" and "reset" have become intermingled by nontechnical users.
There's a link on XDA Developers where a user is asking the difference between a soft reset and a reboot: http ://forum.xda-developers.com/showthread.php?t=620337
Over on Android Central, there's a thread where the people who reply get their vocabulary mixed up: http ://forums.androidcentral.com/htc-evo-4g/15765-soft-reboot.html
What are the differences between a permanent root from a user functionality perspective? What kinds of apps do not work, or don't work well, with temp root?
What is a soft reboot? What are the benefits?
