Thanks lyapota! Slight problem with those two though: the leedroid tweaks app is no longer available on Google Play, and the Insertcoin Kontrol app is also not available on the link you sent me... Finding the apk somewhere else, it installs but FC.
When searching the Play Store for Leedroid tweaks, another kernel control app comes up, and even though it seems to be compatible (color controls work, etc), the slide2sleep option is active but disabling it makes no difference.
Any other suggestions?
Thanks!
