*NEW CHANGES*- "HOW TO SWITCH BETWEEN 2 CORES AND 4 CORES"
To enable and disable 4 cores :Turn off screen and wake up after 3 seconds (DO IT TWICE)
[ eg: Turn off screen and wake up after 3 seconds...
..Turn off screen again and wake up again after 3 seconds ]
- 4 cores get enabled after you do the above. If you repeat the same process it
comes back to 2 cores.
In 4 cores mode: When screen is on 4 cores are active, Screen off sleeps to
2 cores in low CPU boostpulse mode. But it always wakes to 4
core mode.
In 2 cores mode: When screen is on 2 cores are active, Screen off sleeps to
2 cores in low CPU boostpulse mode and wakes to 2 cores only.
**The above is to prevent any accidental activation or deactivation of cores.**
- Do it before starting heavier apps or games if needed.
- Don't do it while heavy apps/games are already running.
- If you switch off screen again it sleeps to 2 cores but will always wake up to 4 cores until you disable 4 core mode.
4. Stability issues and hanging issues of version 5 fixed. SD CARD issue fixed.
The boot up process and bootanimation is slow. Switch off screen once after the boot up process to remove any lag.
