I felt this picture needed a better sun, a happier sun, a fun sun! So, I used Samsung Gallery and added a sticker.
It’s extremely easy to do. Just open the Samsung Gallery app and find the photo you want to use. Tap the edit button, then the sticker button. Browse thru all the stickers to find one you like, tap on it and it gets placed on the photo, you can resize it and move it around before saving. Once it’s saved you can view it using either Gallery or Google Photos.
