VM Heap Tool (root only)


Requires *FULL ROOT* (aka S-OFF or NAND unlock) and *BUSYBOX*. Please use Busybox version 1.17.x as 1.18.x compile is broken!

Notice: Many users have been asking for increased heap size values. I will not be adding them as Android device configurations have advanced over time, with most devices now offering more than enough heap by default. Increasing it even further won't be of much benefit, as such this app is mostly useful for older devices.

Allows to change the Dalvik VM heap size to give demanding applications more heap space (thus decreasing frequency of garbage collection) to speed-up your device and improve overall performance including battery life. YMMV though.

Please note that changing the heap size may affect the stability of your device and therefore use this app with care!

Special thanks for helping out go to Stephan and Anthony :)

I don't recommend this app It worked fine on my GS4, but on my DROIDX(Liquid ICS rom) it boot looped my phone. Tried three times to use thus app after SBFing my phone then installing Liquid ICS again. It still soft bricked my device.

Seems ok Its the right size which means no hidden crap,and if you take time to research your device and read other peeps experience with it,you won't make yourself look foolish by bricking your $700 toy.
