Sir/ Madam, I am using Samsung A 50 mobile device, since more than 3 years. I suggest for a facility in mobile for timer with screen lock. If I set a timer, after set time screen may be close. this will be useful for person who wants to permit anyone for a specific time. thereafter he don't want that the person use his/her mobile. So please provide an option to screen lock after a timer.
I also suggest an option for date and time stamp on photo clicked by the Samsung camera.
It is requested that please inform me if you agree to work on my suggestion. It will be useful for Samsung smart phone user.
