In my older Note2 (which is now broken), I was able to change my Tethering or Mobile Hotspot
SSID name & its password but on my current Note4 (I purchased it as a used set), I could only
enable it but could not locate anything on this Android 6.0.1 anything to change the name & password.
I recall there's a setting where the first letter after a fullstop will be auto-capitalized & the standalone
letter "i" will be auto-capitalized: can't seem to find this setting.
