When it comes to fixing bugs in ROMs, most users don’t care how the fixes are applied as long as they work. So it happens sometimes that fixes are released before they’re merged into the actual ROM. This provides faster relief to some bugs, and devs don’t have to rush to get things merged and re-uploaded. There is such a tweak pack for the Samsung Epic 4G Touch that fixes a couple of bugs and adds some new features.
It was released to XDA by Senior Member Exit_Only. For clarification purposes, the tweak is only available for AOSP-based ROMs. The stock, OEM-skinned Jelly Bean gets to keep its bugs for a little while longer. Here’s everything included in the tweak:
Library Fix for Gyroscope and Compass (Stable)
Several Scripts to increase battery life and performance (Alpha)(major wip)
GPS Modifications for better and faster GPS Lock (Alpha)(wip)
Sysctl Tweaks (Stable)
Build.prop Tweaks (Alpha)(wip)
So while the Gyroscope and Compass fixes along with the Sysctl tweaks are stable, everything else carries with it the YMMV title. Users can expect the WIP items to become more complete as new builds get released. Users have confirmed that the fixes work, so if you want to see an end to your sensor woes, this is a tweak to try.
