1 the nav bar settings is a visual preference setting. some people like the back button on the left (where it belongs like in a book or browser you go back to the left) some like the samsung style of back button on the right.
2. OEM unlock slider option and "safer". Difficult opinion to make , as far as "safer"
ok lets look at it like this:
if your phone is lost or stolen, yes having oem unlocked phone would allow who ever finds your phone to use fastboot and get around your lock code and use the phone. But that would force them to also factory reset it. So your data would be gone., and they would have your phone able to use it.
on the other hand if you had oem unlock off and had a bad update loaded to your phone you might end up with a bricked device that you would no longer be able to use.
and now to the point that makes all this explanation pointless. In order to even be using this modified rom in the first place you must be oem unlock anyway, so it really does not matter.. If you run custom or modified rom you must be unlocked.
I thought OEM unlock options in settings does not do actual unlocking, instead it only permits unlocking bootloader thru fastboot oem unlock command.
If so it might be reasonable to install old V12 Settings app and turn off this option, turning this off will of course not relock bootloader but other apps (possibly malicious apps) who manage to read Settings app user data may "think" device is in original factory state with locked bootloader. Thus such apps might not try to exploit rooted device thus device would be "more secure".
I thought this was reason why so many people asked for old Settings app apk.
Among differences I noticed encryption reappeared in V17 but was missing in V12.
This might be reason against installing V12 settings app.
In ColtonDRG thread he instructs not to encrypt TWRPed, rooted device but since encryption option now reappeared in V17 does it mean I can encrypt such device after all?
I think you provided original OOB images for non-prime devices? Do you recall encryption option was available on factory original V12 device?
Also does anybody is it now safe to reset TWRPed, rooted V17 device from Settings app?
