[Galaxy Grand Duos i9082 General] Paul_Days:
UPDATED: 10/28/13. Battery Stats

After desperately waiting for Samsung to deliver our latin variant (9082L) Galaxy Grand the Jelly Bean 4.2.2 update, and seeing that pawitp sorted out CyanogenMod's AOSP firmware, I decided to build a project in which I could maximize all of the Galaxy Grand -L's potential. I found that the Pure Android experience lacked some features that I use often (DLNA, Robust Picture and Video Gallery, etc) so I added what I consider to be the best available: Sony Xperia Media Apps.

Taking all this, plus my previous knowledge of our device's settings, I give you, The Grand Google Play Experience Edition, inspired by the S4 Google Play Edition (Pure Nexus Experience), and Sony Xperia Media Apps. Please read through all threads and their direction, for some require modding system files. Device must be ROOTED. I am NOT responsible for you bricking your device. This should also work on the I9082. I take no credit in the development of these mods, my credit goes to hours and days of testing out different ROMS, Media Packs, Scripts and Apps from many different sources and people, and making them all work smoothly and stable in our device, to seem as if it was meant to be this way.

SONY XPERIA Z MEDIA PACK

The one thing lacking in pure Android is a robust media package, and this perhaps is the only thing I miss from the Samsung package. Sony has a much more robust and integrated media pack which brings back all the goodies one may miss; Organized and pinch-zoom albums, access to pictures and music from other sources, better audio quality and adaptations. Out of the several ports available, this particular Xperia media pack runs perfectly on the Grand, with the only exception of downloading song information (artwork and track info). And Yes, DLNA if working on this port.

1. Boot in CWM

2. Flash zip

3. Reboot

* DSP Manager must be frozen, stopped or deleted. Sony sound enhancement will now perform that sound processing.

PERFORMANCE TWEAKS

​

There are numerous apps and scripts out there. After trying just about all of them, the following mix and matching of tweaks has yielded the best performance for my device. I am getting a consistent 11400 - 11600 on Antutu's Benchmarking tests and best of all, a steady line of stability and temperature readings. You are welcome to further tweak, but it's been thoroughly test for hours, days and nights. I have gotten really close to breaking 12000, so I'll keep you all posted.

SUPREMACY TRILOGY SCRIPT

Many tweaks in one simple flash.

Features: Better ram allocation, More free ram (clearing cache), Faster GUI, UI processed by GPU, Loopy smoothness tweak, Apps zipaligned at every boot, Faster Networking, SQlite database optimizations, Lag fixer, Smoother LWP animation, Adrenaline boost and more...

1. Boot in CWM

2. Wipe Dalvik Cache

3. Flash zip

4. Reboot

• Download Supermacy Script V3 (Thread)

PIMP MY ROM (BETA)

ONLY USE THE ENTROPY GENERATOR. You are welcome to use other tools and tweaks, but use at your own risk. Noticed further tweaking only decreases performance. The Supremacy Script does a better job and already handles most of the tweaks offered here, with great settings. No other Entropy Generator works as well as this one though. Before tweaking, make Rescue Package is recommended.

1. Select Tools-> Entropy Generator: ON | Feed Interval: 1 sec. | Fill Watermark: 90% | Randon Read & Write Wakeup Threshold: Detect Average |

2. Press Save (Diskette Icon)

SD CARD SPEED BOOST

I read on people suggesting all sorts of cache sizes for their SD cards, and though it is true that it works, this is the way I believe you should choose your cache size. I've gotten 100% speed increase and write, and 50% increase in read.

Recommended optimization method:

1. Download ROM TOOLBOX LITE or PRO

2. In the performance section, select SD BOOSTER

3. Under Benchmark, Run a test a 500MB size and all cache sizes selected.

4. Choose the size with the highest read/write values.

5. Apply cache value. And select to apply on boot. (You can use this or any other SD Card cache app, I use this app for it's benchmarking only)

{PERFORMANCE TESTING NOTES} 10/28/13

BATTERY STATISTICS - People in the CM10 thread are commenting about massive power drains. This is what you can expect from this CM10.1 and my mods. Like I said in the CM10 thread: "It doesn't get more horizontal than this" *Results may vary, depending on software, my device is about 60% full.
