Go to your home screen and select 'Photos'.
Choose a photo and select 'Edit'. (I have just picked a random pic of my gerbils for demonstration purposes lol)
Press this little Rotation icon in the bottom left corner!
Your image will rotate to the right!
If this is not where you want your image, press the icon again and it will turn another 90 degrees!
When your photo is where you want it, press 'Save'.
This is especially useful if you save an image to your device, but it appears in your photos the wrong way round! Please like, comment, follow me and check out my 15 other guides! Bye for now!
