How? I’ve been a heavy telegram user for more than 8 years now. Not a single time I have unwillingly been added to a group I had no interest in or been messaged with any scam message.
I know of privacy settings that limit these, but I have none of them turned on, because I have some people that might add me to important groups.
Not the one you replied to, but I installed lineageos on a old Samsung tab I had laying around and there’s the android native option to ‘pin apps’ which puts the app before the lockscreen basically until you exit the mode manually, meaning you only need to turn on the screen and it’s still protected by password so can’t be used for anything else.
For waking, it’s in the hallway where I have a hue motion sensor. Whenever the sensor notices movement, it’ll send a notification to the tablet with the command to wake the screen and the screen turns on. Pretty easy and straightforward
