Scrotter is an app for Android that allows you to place your screenshots inside the image of a mobile device (such as a phone, tablet, or phablet) and then save your image for publishing.
Many phones are supported, but if yours is not, PLEASE send me an email. I apologize for my delay in adding many recent devices; it's very difficult to find templates of a high enough quality to actually add, plus I've been very busy.
The name "Scrotter" is a portmanteau: SCReenshOT framER.
Scrotter is completely open source, and released under the GPLv2. You may fork, contribute, and report issues at Github:
If you would like to donate, you can purchase the donate app titled "Scrotter (Donate)".

Scrotter is also available for Windows (XP+) here: http://yttrium-tyclief.github.io/Scrotter/
