Thank you best ROM out right now. Kii keyboard is sick all my mods work. You guys just made a grown man cry.

Re: [ROM] Chemistry V4 (1/26/13) "working multiwindow"

Flash the lidroid file from morphology first then the system ui then flash morphology v1.4. Worked for me that way.
[Sprint Samsung Galaxy S III] neonymbus:
Re: [ROM] Chemistry V4 (1/26/13) "working multiwindow"

K to fix morphology, download stock system ui, lidroid.zip, and morphology. From recovery wipe cache and dalvik cache. Then flash stock system ui, then lidroid.zip, then run morphology. Then no more force closes.

Next if anyone is having any difficulties with data as I did, here is how to fix that. Switch network mode to cdma, phone will reboot, then update prl and profile, then switch back to cdma/lte and it will reboot again. Then it should work fine.

Don't know if anyone did benchmarks on v3, but v4 is way more stable and faster. I was overclocking to 1.6 and now I'm underclocking to 1.2 and it's still lighting fast.

Also, I've seen a lot of positive feedback for our developers. Question is, how many of you have dropped a contribution for our hard working developers? I did and I hope everyone considers helping, even if it's a small donation. We have to take care of our buddies, ok?

TWeaker Settings

For those interested in using K47 (ktoonsez kernel) I'm providing my settings file. Just extract to your internal sd card under the KTweaker folder. After extracting, run ktweaker and use the restore option to install the settings. I think this one overclocks to 1.6, but you can set to whatever speed. I wouldn't recommend overclocking over 1.8.

I normally get 18hrs stock battery under normal use (no extreme video or gaming). Again, the link I provided you previously has many other settings you can play with.

Re: [ROM] Chemistry V4 (1/26/13) "working multiwindow"

jaron7,

As I posted my friend, any time you flash a ROM or kernel, they'll be a "settling" period. Just let it settle down and in 24hrs check your battery consumption and you'll see it has improved. Also, consider installing k47 kernel so you can tweak your CPU settings.

Data

Its weird...i havent a single data-issue with any of these MW roms AND im using a Sprint GS3 flashed over to cricket w FULLY working everything. THE only thing i have to do is remove SecMMS and replace w a modded Cricket MMS and inject the correct Apns using Apn backup&Restore. Other than that i have NEVER had a problem w data. IN FACT much the opposite. I am getting a bar or two more PLUS my data speed have tripled using this vs a stock rom...getting about 900-1000kb down and that is great for cricket-for $56/mo. I got the GS3 from sprint 3days before they canceled me for excessive (forced)roaming...so their dumbasses forfeited the contract that would allow me to pay for the phone! So basically got a 6-700$ phone for $200! and now i am saving $60 a month. Crazy--no more roaming necessary either and they are sharing the same network...didnt and still doesnt make sense. GREAT WORK CHEMISTRY TEAM!

Many of us experienced same issue after flashing v4. Easy fix:

2 Go to system update and update profile. Just tap once and wait. Reboot.

3. Go back to network mode and select LTE. REBOOT.

4. Go to system update and update prl.

Re: [ROM] Chemistry V4 (1/26/13) "working multiwindow"

Look at your discharge time. Unless you were heavily using the phone during that time period, having Android system that high isn't irregular. If you think about it, it makes sense. 3% in 20 min is 1% every 6 minutes or so. That means about 10% every hour. So approx. 10 - 11 hour battery life under these conditions. In time, the screen will consume more battery life than Android System. But if you look at the battery monitor, Android System is usually the second highest battery consuming thing after Screen
