Things can be done for future
- Move kernel to a newer version(may based on a vendor kernel).
1. Brings us the fix of CMA which increases over all memory usage when system does not use ion memory.
2. Help us to catch up vendor's latest patches on their reference kernel.
- Move Android to a newer version (4.4.4 at this time 30th Oct 2014) which have better performance.
1. As Android 4.4 has lots of platform optimizations for low RAM device which may also help performance on a device like XO-4.
2. Also can port some parts of the optimizations to sugar as well.
