[Optimus One, P500, V General] Xx Jafours xX:
The 4.3 ROM and Kernel 3.0.8 perf+chocolate on P500 (as well as P505, P506, P509, and other clones), which most have currently, seems to be working very horribly. The battery life drain remains, with my P505 shutting down in less than 7 hours when on sleep (I know, P500 has a better battery life than my P505, but its life also drains life like anything). They do not come with the GAPPS, and there are other problems in getting that application. I had a problem with my AOSP stop working, and a train of those types of messages "Unfortunately, Trebuchet had stopped" when I rebooted the phone. Luckily, I had just closed my browser then, and since the Keyboard did not work, I was not able to search for anything. Lucky as anything, I had recently been to the 4.2 ROM site, and reached it through the History. I then just downloaded it. I'm pretty sure I know why that had happened. My /cache had filled, with only a couple KB's left. So said the CWM recovery message after I had installed the GAPPS. My ROM space was filled as well, even after getting rid of all the applications that I would not use, but still had no space to get the 20 MB GAPPS on there. If I had not been to the ROM site recently, and if it did not show in the site, I would have to go through the unbelievably long steps: Install the KDZ Updater on my computer again (I had uninstalled it and its Adapters months back), and install the 2.2 OS (the only one available with the KDZ Updater, sadly), and flash it. Then would I be able to install 4.2/4.3 on it.

4.3 ROM and Kernel on P500 has very few changes from the 4.2, and has more disadvantages in getting than 4.2. The few added features are such things as adding some "fn" key shortcuts or so, and other minute features that you probably won't give a second look at. All the Developer options still would be there after you click on your phone's build 8 times, in the "About Phone" at the very bottom of setting. The Reboot shortcut in the Power Menu is there in 4.2, along with every other Developer features. The camera seems to work at lower fps than 4.2, but that's my observation. And, as you may know, Link2SD works on both ROM's, though I had a bit of problems with it on 4.3 (like it not linking properly, not showing how much space there is left on the SD-EXT, etc). The SD script works on the EXT 4, and none other on 4.2/4.3. On 4.1, however, it works on EXT 2. The Swapper 2 also does work with 4.2/4.3, but ONLY once you install the Busybox from Stericon (4.2 and 4.3 both come with Busybox-jb).

The 4.3 is currently being experimented with, and people are just taking it from the Jenkins or other Developer websites and posting them all around. There are many more bugs and glitches in the 4.3 ROM, but not coming in my mind right now. Many applications I can install on the 4.2 could not have been installed on the 4.3. I would suggest, though, that you uninstall all the useless system applications from the ROM, just to save space, and maybe add something else in them. NEVER delete and of the applications such as the Phone, Messenger, Trebuchet, Google TTS, Pico TTS, and others. Get rid of ones you don't use, which may be the Voice Dialer. Make sure you search up the ones you delete before you delete any, and make sure, of course, that you make a nandroid backup.

4.3, as my preference, would not be close to a good choice until they actually are done experimenting with it. All 4.3 has in change, as I said, are one or two things, and of course that "4.3" written on the "About Phone". It's no better, rather, worse, trust me, as I have heard from more people, and am not alone in facing all the problems. 4.2 comes with all the GAPPS installed, and is 99 percent the same as the 4.3. I have soft-bricked my phone 7 times, and 2 times with 4.3, only because of struggling to get what's already there in 4.2, and what can be obtained in 4.2 as well.

Please don't mind if I wrote too much. :p I'm just new to posting here (though have known and been to this site for years), and am liking it very much.
