I posted a thread about Photoscape a long time ago... I recently got a new phone and can no longer find it on the Appstore. Am I just missing it or did they stop supporting it? Is there another free app that crops in a circle?
Downloaded it and every single time I tried to use the circular crop tool it crashed and closed the app. To thw point that Google asked why the app kept closing. Had to uninstall it...
Be very careful when downloading any photo related app for Android as many were found to contain viruses, spyware, etc. Adobe has a few on Google's Play Store. (Adobe Photoshop Express is one of them).
I have a Galaxy S8 but it's running version 9. You can find the Android version on Settings; About Phone; Software information.
