Some of these you’ll know, hopefully you’ll find something useful. I’ve tried to group the tips to help you focus on areas your phone is not performing the way you’de like.
Power Saving
Turn off anything you’re not using. Things like Location, Smart Stay, NFC, Bluetooth etc.
Useful Fun
Screenshot
Press & hold down the Home+Power buttons at the same time to grab a screenshot. You’ll hear the camera shutter sound and see a white border flash on the phone.
Blocking Mode
Allows you to set a timer to do things like block calls and/or notifications & alarms from everyone or allow select people between say 11pm and 6am, that way you can get your beauty sleep without interruption.
Quick Access Specific Settings
Pressing and holding down on any of the toggle buttons for things like WIFi, Bluetooth etc will take you to the settings page for that item.
Show Battery Percentage
Settings > More > Battery
Check “Display battery percentage”
Speed Up S4 Mini
Turn off S-Voice
Double-tap the Home button, this should take you to S-Voice, if it doesn’t it is already disabled.
Click the menu button, lower left, select Settings, then uncheck “Open via home key”
Turn off Transition Animation
This will speed up moving around your screens as the transition animation from one screen to another takes time.
You’ll need to enable “Developer Options” see below
Go to Settings > More > Developer options
Scroll down till you find Window animation scale, Transition animation scale and Animator during scale. You can turn these off or speed them up – your preference.
Developer Power User
Turn on Developer Options
Go to Settings > More > About – scroll to the bottom of the screen
Now scroll down to “Build number”, tap it 7 times, you’ll see a countdown appear which will tell you how many taps left to enter Developer options.
Samsung Test Menu
Go to your dialer and enter *#0*#
This will take you to the Samsung test menu, where you can check how well your Samsung is functioning.
