Help with resolving Gnex performance issues

Stock my Gnex was a rocket, but after I started ROMing it is a laggy MESS. I do a clean wipe on each ROM install, but even before I load up any apps it stutters like crazy. The nav buttons can take seconds to respond, swiping through home screens jerks really bad.
Currently I am running the latest CM10 nightly JB rom, but it acts this way on any ROM I have tried. It seems to be a file system issue...the lag feels like the lag you get when you update a lot of market apps all at the same time...except all the time. Opening Google now can take up to 30 seconds on a clean install.
Any ideas on what may be going on?

Suggestion-1: Flash stock once again and check whether the same happens. If the same happens again you may contact for phone replacement.
Suggestion-2: Try Wiping cache and Dalvik cache in CWM and reboot. Many times this has helped my phone to work fast.
Suggestion-3: There are many other ROMs around. Try them out.
I am not an expert to suggest you. But hope above works. Hope any more suggestions come up for you.

I have tried every popular ROM out, and wipe data and all cache on every install. They all act exactly the same. I really think there is some kind of bandwidth issue on the system partition. Maybe the flash storage has degraded? I will try flashing it back to stock to see if that would makes aay kind of difference.
I had been planning to RMA it anyway because of some major screen burn in issues...but was trying not to because I bought it through Letstalk, so I need to deal directly with Samsung for a replacement...which means being without a phone for a week or two.

I believe prior to flashing you should do data wipe cache and wipe System also :/ don't know if you've tried that it's under mounts and storage in CWM =)

I just setup a Samsung RMA for the screen issue. Hopefully they simply give me a refurb instead of repairing it.

logcat, df, dmesg and in this case, maybe a 0xbench math/vm test or it didnt happen.
not sure how a custom rom would be slower than stock.
i dont think its hw issue, or stock would suffer from the issue.

My apologies, I wasn't clear. I meant that the device worked great while it was stock, but now it runs like crap. Custom ROMs may or may not have anything to do with that which is why I mentioned it. I will say that the stock-ish JB leaks ran flawlessly, while the ICS custom ROMs I was running before ran like crap. After I moved off the JB leaks to custom JB ROMs it started to run like crap again.

I thought I'd update this in case anyone else has ever had a similar issue. As I was preparing the device to be sent back to Samsung for a screen defect, I flashed the stock 4.1.1 factory image, and locked the bootloader. It feels like a completely new device..flying faster than I have ever seen it go.
I do not know why this resolved my issues and a wipe data/clear cache never did. Maybe encrypting the bootloader did something to the file system a normal wipe data doesn't? But then again the JB leak seemed to run well too if memory serves..so I just don't know.
Now that it is running properly for the first time in months...I really cannot stand sending it back and being without it while waiting for the repair.

It did it on ICS ROMS too, but now that i think about it every ROM I have tried was based off CM9 or 10. Either way it's on the way back to Samsung now (for screen problems) so hopefully the next one doesn't have this odd issue.

[Q] Jedi Knight 3 and NCF/Android Beam

Is anyone else experiencing an issue with NFC/Android Beam not showing up on Jedi Knight 3? The weird thing is it has not been consistent. One instance of flashing this ROM and I had the feature available, but it was only the once, unfortunately I can no longer get that feature to appear in my settings. Any suggestions?
EDIT: So after trying to use Tweakbox and doing Hot Boot my phone got stuck during boot. I was going to try Darkside as I have heard it is supposed to fix the boot-stuck issue. I accidentally downloaded the wrong Darkside tools and it erased my ROM. Re-flashed the ROM and da-da-da-daaa NFC/Android Beam are right there....the only thing I did differently this time? I waited 20 minutes after flashing instead of 10...

Are you sure you that it was on that build or on the old one? I've seen devs taking NFC feature off before

That was something I began to consider but then realized that at one point, after flashing this ROM the NFC was there. I have also spoken with the developer and he is unsure as to why either. I am not really sure I need it right now though because it seems like it is still too new, my brother and his fiance both have the S2 and I tinkered with their Android Beam a bit, but was somewhat displeased about the inability it seemed to have when it came to sharing pictures, videos, or music in your gallery. YouTube, Facebook, the browser and stuff like that was great for it but it didn't seem so much the same when it came to personal files.

Try flashing the NFC enabler: http://forum.xda-developers.com/showthread.php?t=1822447
Just make sure you download and flash the right version for your ROM.

Thanks, but I accidentally fixed the problem this morning...lol...dunno why but I did a Darkside Super Wipe and re-flashed the ROM, bam everything works! I even saved myself the trouble of reinstalling a bunch of apps.

if you got cwm 5.0.2.7 do a darkside super wipe.. This will solve problem, and reflash the ROM

I ended up switching to TWRP due to all the issues with CWM, still had the issue but did DSSW in TWRP and everything got fixed...lol....funny since DSSW was designed to fix issues with CWM when flashing...

I have a Motorola Droid Bionic & am seeing the same issue on my phone with CM10. Browsing along with the stock browser & then the browser window is gone & I'm back at my homescreen. No warnings for me either.

Phone stuck on app optimization

Hi guys, i swear i searched! for like days! i still haven't found out how to solve this issue. problem started when i tried hellybean a few weeks back, and then i heard someone on the thread said to try and use the latest beta uber kernel at the time, and i did. What end up happening was that my hardware keys are dead, the lights still works but very dim, i think this is because of the swipe to wake thing where it leaves your hardware keys on 24/7 as long as the phone is on, which is not that bad because i'm now used to using the nav bar. but the real problem is that now every time I install a rom that is not JB 4.1 (haven't tried 4.2 though) i.e. 4.3, 4.3.1, it gets stuck at the app optimization screen, it would go about half way through optimizing the apps, and then just reboots itself, and it'll do that over and over, like boot loop but it can actually go into the rom. So i think this is not as bad as a situation as soft bricking or hard brick, but i just really don't know what the heck is going on to even try and fix it. I've tried odin, thinking that there may be something wrong in the boot file, nada, factory reset, nada, the only thing that worked was installing the 4.1 roms, i think it is because the 4.1 roms don't require app optimization.
If anything maybe anyone out there can help me find a way to disable app optimization? maybe that'll let me get into the rom.
btw, i dont really mind using 4.1, but i really want to try the jedi rom, but having my hardware buttons dead and jedi rom being TW and it doesn't seem to have a nav bar make it impossible for me to use the rom, so i've only been able to use cyanogen 4.1, which are great but they are pretty outdated, so if there are anyway to fix that, lmk too.
Anyways, any help would be appreciated thanks a ton guys! sry for essay!

have you used the infamous cache wipe? http://forum.xda-developers.com/showthread.php?t=2235141 try this and it should fix your issues its because your going from AOSP/AOKP to TW they dont like each other lol follow those instructions and you should be good. also what recovery are you using to flash these?

Lol actually the problem started when I was on 4.3, and then upgraded to 4.3.1 helly bean, in which i tried to use the beta uber kernel, that was when the problem started. So the only roms that allows me to get pass the optimization screen were the 4.1.2 roms, which were TW, pananroid, like i tried a bunch, like super old ones, they all worked, just that when i try to get any rom higher than 4.1.2, it keep going back to that. And yeah when i tried to upgrade from jedi to aosp, to tried using infamous cache and it didnt work :/ because i've heard that's what would fix it... and lastly, Im using twrp 6.1 i think, not the latest one.
Thanks alot for the reply!
PS. I see you running slimbean 4.2.2, how is it? any probs? maybe i can try a 4.2.2 if this doesn't work out, i havn't been able to get any 4.2.2 roms cause the links are all dead, so idk if i'll have problems with 4.2.2. if there's anyway you can link it for me that'll be great! thanks!
PSS: also i've tried odin, but idk if that actually wipes everything, i'm having a feeling that it might be a script problem or something because it goes into the rom once, but it just refused to work and after like 10 seconds it reboots.

quick question are you trying to restore 4.1/4.2 apps on your 4.3 ? apps dont play nice like that sometimes .. also your not restoring any system apps are you? Personally i love all the ROMs/Mods the devs put out for us but im one who likes it really stable with very few bugs so i like to stick with stable ROM's so thats why im still on 4.2.2 its nearly perfect no issues here brother . When you flash the rom what are your actual steps in detail please from the time you boot into recovery until you finish so i can get a better idea here

Ey thanks for the reply, ok so first, I did not try to restore any apps or system apps, I even odin so everything were wiped cleaned. So really dont know whats going on. After I updated to a newer hellybean, not newest by now, and a beta uber kernel, this happens. I see two other people having the same problem too. Also I tried to use 4.2.2 roms, did not work
Anyways any insight would be apreciated!
Thanks!
One more thing, I tried twrp 2.6.1.0 to flash as reccomended by all devs and still no results. :/

Damn sorry brother that's pretty frustrating try dirty flashing helly bean and just wipe dalvik and cache and see if using the stock kernel helps first then see what happens :banghead:

Help this book please!!

I installed Hyperdrive 16 ROM for my phone about 6 months ago. I did it through the installer that comes with the rom. This is probably the only reason I didn't brick. Anyway I have messed with it so much and dl'd so many different root programs and so on and TRIED to install different roms that even when I do go back to my Tit backup and restart in Recovery... The only .zip file I can start up is my RLS16 ROM. I cannot revert back to stock cuz I installed it without backing up properly. It seems like people that do have Hd rom actually enjoy it. I don't really know how to use it but learning. I get error messages from Google... like when I open Google search from home screen it will force close and freeze... Every time. I get a Sec. And a couple other errors msgs after reboot. My play store crashes and so does my contacts and my sms app wouldn't work to the point I've had to reinstall Hyperdrive from recovery mode 3x in 4 days. I am so annoyed. I know I messed up and I like to twerk options and the way things look lol I just wanted a new rom. Any suggestions or...? Oh and I have a mac book that is why I don't do anything from the computer cuz idk of any actual working android to mac programs without paying $40. Idk what I'm saying lol I messed up. What can I do? Thanks guys...
