guys, please DONT drain your battery to 0% unless you doing calibration. it will hurt your battery more.

about the reboot problem, please tell me which CPU governor you using and what's the max and lowest frequency? i suspect some CPU governors i added are not as stable as others. so far, i am using OnDemandX, with max 1.4ghz and lowest 245mhz, have not encounter any reboot.

about USB disconnect, i suspect hardware problem. cant be sure, but it should not be related to ROM/kernel since the only changes i made is swap and increase the buffer.

i guess you are refering to Samsung Clock widget that does not update. if happen if u "Clear Memory". it happen even on stock ROM. i recommend not to use "Clear memory". android take care of its memory. moveover, the Cow In Black has 100mb more zram, so you should not worry too much about the memory.

CPU governor are things like "OnDemand", "SmartAssV2", etc. You can change that using tool such as "Antutu CPU master". If you have not change that before, it should be running on "OnDemand" by default, this should have no stability problem since it is the same as in the stock ROM.

Based on your explanation, you have not OC the phone as well. So, your phone reboot should be OC issue. And since it is not related to CPU governor (you using default OnDemand), the only thing left could be the undervolting which I set on 1.4ghz so that it save more battery. If auto reboot happen often, you should try the non-oc version instead.

One more thing, one of the best thing about my ROM is having all those kind of CPU governors so that you can try and find the one that suit you the best. For example, MinMax should give you really really smooth lag-free experience, but at the expense of a bit more battery life. OnDemandX should give you more battery life if you switch on/off screen often like me because of its early suspend API. Try experiment with them. It'd be a waste if you dont.

look interesting, wonder what kind of GPU it will use and it's pricing. samsung is crazy with so many products. this Ace 2 is obviously in the same price range of SGW... new user will probably have more choice.

but for those who already own SGW, may want to look at this:

that is my next target

ya, i was surprise to see Ace Plus selling at SGW price! lowly spec, but about same price. it's white, so, some clueless chix might fall into it.

i think they realise that taking resource from the "support" and put them into creating new variant of phone may make more $ for them... since Android has strong support from community anyway... like, why spend resource making ICS for SGW when android community already making a way cooler CM9 for SGW?

not saying that i agree with their tactic.

The RAM score is really nice. Need to research how to get higher memory score.

sd card is not everything. if not mistaken, stock ROM using CFQ IO scheduler by default, whereas arco68 kernel changed to using BFQ.

read more about BFQ here: http://algo.ing.unimo.it/people/paolo/disk_sched/

"At the same time, BFQ achieves up to 30% higher throughput than CFQ with most workloads"

i added Simple I/O scheduler into my kernel, which has even better IO score compare to BFQ.

Make sure your phone is not connected to PC and has USB storage enabled or something.

Improved Memory Performance. New Antutu score 4569.

like most app in my phone, i remove the access internet ability. so, Antutu cannot really go online. i'm happier if someone that uses my ROM to submit their score and top the chart.

Managed to integrate the "Scorpion Bionic Optimisation" into my ROM... look at my memory score.

ya, it's possible. (no offence to IwanAGP ). in fact, some android uses already doing that with Swap drive. this stuff has been in *nix for years. you partition part of your hardisk (in android case, internal storage), and make it as your Swap drive.

a swap drive will extends your RAM. the kernel automatically stored unused (or rather used) memory into a swap drive and free the memory for other app, in OS term, paged the memory into swap drive.

however, android (although it is linux based) has swap drive disable by default. android implement memory management in a slightly different manner. android WILL kill app in the memory when it's out of memory. this is what they call Low Memory Killer. but each app got notified first, and they can then save the progress, etc.

even thought default is not supported, some custom ROM maker has swap drive capability. look more here: http://forum.xda-developers.com/wiki/SD_card_partitioning

yes, there is performance penalty.

now, for something a bit more advance. i implemented zram in my ROM (since 5th ROM). zram is a compressed ramdrive. a ramdrive is like a hardisk (or internal storage), but it's in the RAM. so, it's as fast as the RAM. but in this case, it is also compressed. slower a bit (using LZO zip algo which is very very fast in unzip), but still much faster than sd card / internal storage. and in my 5th ROM, i created a 100MB zram, and then make it as the swap drive!

meaning, in my 5th rom, you will have a swap drive in the memory! having a 100mb zram is like having 200mb of swap drive in the memory. so far, there is no slow down, even in benchmark. so performance hit is probably neglectable. read more here:

playback recorded video from phone already fixed in the 359Mb ROM.

if you Available memory is 360MB, you need to flash to the 359MB version from my XDA first page.

Will release soon, but still working on the Power reboot, etc...

V6 ROM, i promise u 5k of Antutu score!

Interesting. I have not any test of Flight Mode. Will test it tonight.

I put it Flight mode overnight... this morning... everything is........ fine!

will ask testers to help test this...

wow, u slept until 2pm!

about OTG, i dont really understand much about it. any link to read about it?

i m really looking forward for your test result! i m also pretty confident that you will be surprised to see your new Antutu score.

i got that when i first brought the phone. i thought it was broken, wanted to go back to shop and change it. my friend, who used Android before, told me, "restart phone and see..."

apparently, this is Android problem. google "android phone cannot hear"

WOW! what is ur max cpu speed? it look like overheating to me! take out battery, let it cool down.

boot into CWM, flash back to stock or something....

8xx cannot overheat... by default, after reboot, max = 1.4ghz, CPU governor = OnDemand (before Bionic). at this setting, and if there is nothing running, CPU speed = 245mhz. in theory, should not overheat.

but that's in theory!

u should let it cool down first. then, try go back into CWM and use restore so you will not lost everything...
