Optimising your Android mobile device can involve a lot of messing around so it’s always helpful when developers build tools for themselves and share with the XDA community.
XDA forum member appelflap is one such member and the dev’s latest contribution is an Android app that lets you mount the system directory with r/w permission or r/o permission.
You can mount the dir on demand or tell the app to mount the dir every time the Android shell is loaded. You also have the option to remount the dir as r/o.
The mount/ system (rw/ro) application is available for free in the Market. For more information, head on over to the application thread._________
