One of the older versions is working 100%. You just have to copy the apk into your system folder and then either wait for it to appear in app drawer or just reboot. I loved this app on my previous phone but not on n4. Its only advantage is the long touch burst mode with which you take continue shots very fast and clear. If you still can't find a working version I might have it in my drive folder so just pm me to give you a link.
