[Android General] garringm:
Tweaking, Better Memory Management

To Start this post I want to clarify that the device I am referencing is the A2107A-F model. But theres no reason this won't help the other variants

I've been very suspicious that the lag and other issues I've been having with my childrens tablets were due to poor development of this little guy. Last night I went through the rooting process which I found I was not able to use the "patient" version in the beginning of this thread. I had to use the MTK tools to root. I read the Specs of the MTK6575 chip and I knew I shouldn't have been experiencing these issues, It was more than capable of handling the loads my children were giving it.

After installing Root and CWM I made a full backup of the ROM on each of the Tablets. I do plan to make a ROM dump clean it up and upload it incase someone may need one.

Secondly I removed all bloatware that I believed the tablet and the OS wasn't dependant on. This made a huge difference in responsiveness of the tablets.

Third point I would like to make was the biggest improvement overall. I ran the CoD tweaks as I had previously mentioned. WOW:victory: I couldn't believe the performance increase. I have used these tweaks on a lot of my other devices so I fiqured I would give them a shot here.

For anyone that's interested here is the link, read and follow directions and you'll do just fine. Yes you have to be rooted.

In the last part of the guide for SD tweak I have not found a customized kernel yet so the init.d tweak is not applicable

What prompted me to do this was the fact that the device would literally run out of RAM. I have seen them drain it down to <30mb of Free RAM space. Now it seems to be maintaining >150mb free RAM space. Major Major performance increase.

If I run across any other tweaks and what nots for this gem I'll post them.

EDIT:

I also need to add that after after I removed the bloatware and just before I did the CoD tweaks I did a full factory reset. This will purge the /cache and /data of all the old files. I haven't figured out if it will do the dalvik-cache though. Then you are set to do the COD tweaks and on your way to much more improved experience with you tabby

I have been wondering if the only difference between your Device and my -F device is in the Kernel. I have a sneaking suspicion that ALL the hardware is the same and intact and is only being limited by the OS. Such as you 4gb vs 16gb issue. I could be dreadfully wrong though, its been know to happen.

What makes me wonder this is the fact that I have every app in my system/apps such as Contacts, Dialer, and engineering mode but they are not being used by the OS. Well I should say they are not accessible for me. It's also my understanding, and again I could be wrong here, Lenovo could not get FCC approval fast enough in the US to run these on the carrier networks. I think I read it somewhere when I was deciding whether or not to buy them. SO what I think, since these are just cookie cutter builds the easiest thing to do was modify the OS and Kernel to make the different Variants.

I would very much like to figure out getting them to work on mine just for the contact management and engineering mode. I may even try flashing one of these -H ROMS to see what it will do to my device.
