Updated:(3/6/2011) Lets Solve G2x Freezing Issue (Solved:Random Freezing in standby)

I know there are countless threads related to G2x Problems but none of the threads are focusing on isolating the reasons of Freezing Issue. I have recently upgraded my phone from Galaxy S Vibrant to G2x and i have to say i love the hardware and performance. Only Issue for me is random freezing.
After using the phone for 2 weeks and trying 3 roms
1. Stock
2. EB 1.04
3. Dark Sinister 1.1
I have come to a conclusion that kernel and rom is not the solution. At least not for me.
So i will try to solve the problem using hardware testing.
From my past 2 weeks experience.
1. Phone Freezes at night during charging
2. Phone Freezes when ever i turn off/on wifi and bluetooth and gps and Data (4g/3g) (Still have to figure out which of them is the cause. Cause i usually turn all off when i need to save battery).
Test Day 1
For Reason 1
I am using SetCpu and have changed Min from 216 to 312Mhz. I am trying this because i think very low cpu usage in standby for a very long period causes the phone to freeze. Its a Hunch i am not sure.
For Reason 2
I will keep wifi, Bluetooth and GPS off.
I will keep 4g/3g Data On all the time.
To My Surprise its been 16 hours no freeze. It includes charging at night. Lets see how long i can go without a freeze. Upon freezing i will make some changes.
Update 31/5/2011 (Test Day 2)
Ok its been more than 40 hours and not a single crash...
I removed the following possibilities as well....
It wont crash upon excessive usage.
Also Normal Heat up does not cause the crash.
As i have been playing Samurai II Vengeance all day long... Until I ended it. Several times charging along playing. I even played it on TV using HDMI. Not a single crash. I used to have around 3 crashes a day on stock rom when i unboxed my new G2x.
I also started using GPS from today. So lets see how it goes. I will update it every 24 hour.
Update 3/6/2011 (Test Day 5)
Ok i am considering Random Freezing On standby as solved because i havent had a single freeze at night after setting CPU Clock at 312 MHz using SetCPU. There are also other comments that back up my solution. I am considering this the solution of one problem.
2nd Issue of freezing while using cell phone apps is because of certain applications that are either buggy or not compatible with tegra Platform. For that i will start another thread with individual application testing for all apps that can cause the system to freeze or crash.
Please Discuss apps System Bloat-ware/User Apps that cause your G2x to Crash or Freeze in the following thread i created:
http://forum.xda-developers.com/showthread.php?p=14399089
Thanks for all the feedback.

Luckily I dont get that issue, buy I think this is a good test :u

Good point. I have not had these issues but i do have trinity kernel and minimum speed is 300
G2x with CM7 and trinity kernel

All you have to do is be careful what apps you install. I've had the phone for over a month and the one time it rebooted or froze was when I used an app the phone didn't agree with.
I am almost certain that people are experiencing reboots and freezing because of the apps they have on their phone. Hopefully the update will solve the problem because it shouldn't be that way.

In my opinion, the shut down has to do with temperature of the phone. As long as I keep the phone cool by not charging and multitask with other things, then my phone is fine.

I used to think the same thing but the problem is my phone gets hot and works fine. I am almost positive it has something to do with an issue in the kernel that's being exposed by certain apps. My Xoom on release had reboots and SOD and it went away with app updates and removals. It also has Tegra 2

Do you or @kangxi remember what Apps gave you issues?

it has to be a driver issue, its virtually the only explanation for why devs have not hammered it out yet or even CM7 team for that matter... it has problems on pure AOSP which leaves drivers or overheating (unlikely)... LG has to come up with the fix because they know their drivers and hardware better than everyone else...

Well the obvious problem I see is that they are all based on the stock rom. Try using one build from AOSP or a CM variety.
I didn't stay stock long but I did have reboot using the leaked Gingerbread (which is what EB is built from). I don't follow it but one is based off the stock 2.2.2 rom and the other is based off the leaked 2.3.3 rom.
I had nothing but problems with the stock roms. Thus your problem I think. Move over to Bionic, CM7, Gigglebread, or something.
I tested my phone and I didn't have a reset in like 5 days (which then my battery died overnight because I forgot to plug it in). I usually crackflash the CM nightlies and haven't had any problems with reboots or any issues requiring a reboot (aside from the flashlight killing audio, but just don't use it).

There are definitely two problems - software and the battery. I used to way more problems until I exchanged the battery for a new one and that solved most of my issues. The issues that remain are definitely software based.

Thanks for this information/ Changing the minimum speed didnt affect the battery life but it has survived two nights without crashing. So i am planning to keep it at 312Mhz min.

I Completely Agree with you. Some Applications do cause system crashes. But I have removed all the t-mobile bloatware and i only have few games and GPS apps. All games are from tegra zone. So I am sure they are supported.
For GPS App i am using Copilot and it didnt crash on me once.

I just installed setcpu and set minimum to 312. I'm keeping everything else the same to see if this change has any difference. Will report back.

Looks like you are gaining progress. Sounds like keeping the processor revved up a little more does the trick.
It would be a simple fix for people to try that have reboot issues. I can't get mine to reboot, so unfortunately I cannot help you. My contribution was to resist from flashing for as long as possible to test how long I could get my "uptime" to. I got up to 127 hours when I passed out without charging it.
I'm running 20 hours now because I forgot to charge it again (seems to be my only problem, lol).

Looks like you may have fixed your rebooting issues. It sounds feasible that the clock speed could be causing it. I never had a reboot so I can't help you out but I can tell you that I have a profile under SETCPU that clocks it at 216 min and 216 max when the display is off and I don't have a problem. I wonder why the low clock speeds would only effect certain devices? Maybe it's certain apps that stay running in the background (since there poorly written) that require higher clock speeds than what the G2X gives at idle?

I've definitely noticed that the G2X wakes up faster and smoother (fade in from screen off) when min is set to 312mhz that's for sure. if this is all it will take to stop the reboots, I'll be super happy because otherwise this phone is just amazing.

Have you noticed any changes in battery usage? I haven't really played around with SETCPU much but can the clock speed be set lower and if it can, have you tried slightly lower settings than 312mhz?

y are u guys using setcpu? and its def cuz the min is too low faux has his at 400 and no problems morfic also has his a little higher then what is it i think 216?? thats too low thats y setcpu isnt supported yet.....pimp my cpu

Someone asked me a question earlier. Only app I had issues with was fring. Soon as I opened it and started playing around with it, phone rebooted.
I uninstalled and it never happened again.

No clue what you're trying to say but setCPU works fine. At startup for first time I selected Tegra2 and it works great. I have max set to 1000 and min to 312mhz (default was min to 216mhz). I'm running stock ROM but with root. that's all.

well thats y it works for u, u cant overclock over a thousand mhz so in ur situation ur ok i guess it only applies for people running a custom kernel then setcpu doesnt work, then u would need pimp my cpu

Infuse is getting slower and slower?

Hi sense I got the Infuse almost two weeks ago the phone is getting slower and slower and app's are starting to crash more. Has anyone experiencing this? It reminds me the Captivate and the Vibrant.

Mine seems to be getting laddy. Cant really tell for sure yet why. Apps open slower, such as root explorer and some others.....

Mine too, I have all the same apps installed sense I got it and I font know why but its getting laggy. I have it rooted and has stock. I restart then its on for couple of hours then gets laggy, and I check the processing nothing out of the ordinary.

Sometimes a reboot every once in a while can give a fresh start

Yeah. Im still new at this. Im not rooted and on stock rom. For some reason my phone crashes.

I agree. Using custom ROM's are pretty much like getting a heart transplant. I am running Infused 1.5, and my phone seems like a totally different device. It's more stable, and a lot more responsive, plus all of the AT&T bloatware has been removed. The only time I have to reboot is when I make a change that requires a reboot (i.e. changing LCD density). If you are up to it, I seriously recommend looking in to a custom ROM. Check out the "Infuse 4G Android Development" forum.

+1 on Infused 1.5....buttery smooth

Clear memory. Hold home, task man, ram tab, click level 2, and clear. Maybe a temporary fix but it works for me.
I don't have time to restore apps one by one.

Do you have SPAREPARTS from the market? if you don't download it and go into WINDOWS ANIMATION/set it to FAST and also go into TRANSITION ANIMATION/ set it to FAST as well. this will give you a faster experience.

Backup Apps and Data- Wipe - Don't restore everything at once
I've had this happen to me on both my Captivate and now the Infuse running stock or custom ROM's.
The fix I tracked it down to was...drum rolll. APPS!!!!!
Each app thats installed takes phone resources. If the app is active in the background, when others are all active together, just like a PC, it'll slow it down.
Don't restore all apps at once. Troubleshoot by noting each app install and how the phone behaves. If you were fine before an app or other behavior then things slowed down after, reverse what you did by uninstalling and rebooting. See if the behavior persists.
I had Infused running fine till I added CNN and HuffPo apps. Both of which have background notification services running. After installing them, my battery life went to pot even with JuiceDefender ultimate. So I uninstalled them, fully charged up, went to CWM and reset battery stats.
Upon reboot without CNN and HuffPo, battery use is way better. I did that a couple of days ago so I'll install HuffPo and CNN again one at a time to see if the problem comes back.
Moral of the story. Watch the apps you install. These phones are like small PC's. Be mindful of the effects of the software you install.

I think its same as captivate Samsung is doing something on the file system that's why it gets slow after a week

as a general rule I automatically disable background updates of every app I install

Infused 1.5 was a big win over stock. Switched to Bionix 2.0 and now on Infused 2.0. I think Bionix was slower but more stable than Infused 1.5 (both Froyo). Infused 2.0 (GB) seems to be faster and more stable though only running it for a couple of days. About to drop in Infusion-GB OC/UV kernel. Looks like it will make it even faster.

Can't be sure but it may be that you have too many apps running on. Each widget from a different app runs an app at startup. I just run Battery Monitor Widget.
Lots of other apps run at startup too. Astrid, Skype, and other calendar/messaging apps are included. Some games (eg:"4 in a row") start at boot though I don't know why.
And the stupid Google market has the startup on boot permission hidden.
Some apps allow you to disable auto start, others don't. I tend to delete those unless I really like them.
My new favorite app manager, Gemini App Manager, makes it real easy to find these apps. Just scroll the list of apps looking for ones that have an orange "AU" icon. Gemini App Manager runs better with root but fine without it. And, yes, I know it has an orange "AU" icon next to it. I just think it's worth it.

Many of the complaints I saw from the OP are complaints I've heard frequently about RFS. One of the main reasons why Stock Is Bad.
RFS is so awful that converting it to ext4 has a well-known name - Voodoo Lagfix.

You can also try advanced task manager

[Q] Can you fix screen-on lag? AKA Lock screen lag

I searched the forums and couldn't find anything regarding this issue with sgs4g...
I have have tried several ROMs (stock GB, ICBINB kj1, Valhalla, Octane), and all seem to be laggy in terms of the screen actually turning on when the power button is pressed. I don't know if this is an issue with customs ROMs or if it's the phone itself (though I don't think it was as bad with stock KD1). It only takes about a second or two for the lock screen to appear, but most other phones i've seen are pretty much instant. Any thoughts on speeding up the responsiveness of lock screen appearing? I wasn't sure if v6supercharger works for GB roms so I haven't tried that. It's just annoying having to wait to check the time. Thanks for any help! And I am VERY new at all this so please be detailed if you have a solution
Currently I am running
Valhalla 1.3.2 (GB KI3)
Drhonks KI3 kernel
Adrenaline shot vXIX

Are you using set CPU or some other program that can set custom battery levels? If you have your phone set to throttle down to less than 400mhz when the screen is off then it will lag when you wake it up.
Sent from my SGH-T959V using XDA App

Nope. No special settings to adjust CPU Does anyone have a sgs4g that wake up quickly? If so what ROM or settings?

Interesting, I have the same issue. Figured it was just me. Seems sometimes I have to hiy the button a few times before it will come on.
Sent from my SGH-T959V using XDA App

I think that happens to everyone.
Samsung just makes their buttons differently, you actually need to hold them down rather than bump them unlike most phones.
GB is still not official, but I think that it may be because of the CRT on animation.

Yea, it very well could be the CRT animations. Though even when I first got the phone it wasn't super fast in waking up. Oh well, guess its just a Samsung thing, thanks for all the tips and thoughts! On the bright side, I ran v6supercharger on my phone in an attempt to fix it... It didn't fix this issue but the phone is almost twice as fast lol. If anyone still has a fix for the screen-on lag lemme know, otherwise thanks everyone!

I just assumed I had been to punishing on the power button when I thought I had bricked my phone that now it responds slower lol. But I have noticed the same issue that some times I must press it twice to get it to wake. Glad to know it maybe an engineering issue with the actual button rather than a side effect of wear and tear. Would like this phone to last another year at least.

I am on black ice stable, and this doesn't seem to happen to me. I remember it happening to me a lot on gingerbread roms though. I suggest to get rid of any task killers, the apps have to stay in memory if you want them to load up quick.

I'm running Valhalla 1.3.2 and my phone wakes up instantly. The only time I have ever had any lag was when using setcpu to force the clock speed down when the screen was off. It was annoying as hell, so I dumped it.
To define what I consider no lag.
Hit power, screen comes on immediately, swipe miui lockscreen, there is the desktop.
My phone does it faster than I can read the sentence.
Valhalla 1.3.2
Honks KJ1 Stock Kernel w/CWM / EXT4
KJ3 Modem
XIX tweaks
V6 Supercharger
Go Launcher EX
UV @ Dsexton's Values

Note: I only recently add the V6 Supercharger and it made no difference to wake up time for me.

Thanks for letting me know that it is possible. I run the exact setting as you, except kernel KI3. I'll try flashing KJ1 and see if it helps. Otherwise I'm stumped. Thanks!

[Q] PhoenixBlood issue

Whenever I have the lock screen disabled and reboot phone I get a systemUI fc every time and also half the time I attempt to boot into recovery through the reboot menu the phone just locks up fresh wipe and cleaned the cache or whatever is this a common issue in 1.7?
Sent from my LG-P999 using Tapatalk

The rebooting issue is common with trinity kernel which is the one used with PB I think. So you can flash a different kernel if you'd like , I suggest faux's as it's on par with trinity in my opinion. Or you can just power off the phone instead of rebooting
I'm not familiar with the lock screen issue though as I like having a lock screen

I might as well use faux then, I don't really tweak anything on my phone and have been using faux v48 or something since I read it would improve my battery life but I've seen no evidence of it but if it's going to fix the freezing issue might as well stick with it. I use executive assistant app since I can instantly read and respond to my emails, missed calls, and texts from its own lock screen
Sent from my LG-P999 using Tapatalk

Have you tried using a different rom, not trying to diss PB here or anything, I personally love it and have used it for a long time, I switched to singh-ui because I needed better battery life, even though I'm not a big fan of miui just because it's kinda iphoneish and I hate iPhones with a passion, anyways battery life is amazing using the stock kernel it comes with and its very smooth as well
If you do choose to try Singh-UI use the stable version

ROM suggestion

My fiance has had her charge for a while now and she is starting to get fed up with the battery life and lag. We have gone as card as turning off the 4g but she is still unable to make it through the day on a cullen charge with very little use. What rom would be best for improved battery life while maintaining the look and feel of touchwiz?
Thanks

I would say your best bet is eclipse or tweak stock. Not really touchwiz but very great roms.
Eclipse thread can be found here

Tweakstock you'll see in development section.

I recommend using eclipse or tweakstock for a rom. But you may want to just try imnuts custom kernel first and under volt the cpu. http://rootzwiki.com/topic/137-01-30-12peanutbutta-jelly-time/ That would improve the battery. If you're still not satisfied then try a rom with the kernel.

If you phone is ROOTED. You can download "battery saver" by Antutu from the Market(free) and try out for 2 days. This may help you with your battery without too much hassle.

What!! I'm running it right now with Tweakstock and PBJ kernel and it really really save me battery big time. I have tried to under volt, and turning off 4G, lower screen settings etc.. not help. Max I can get is 6-9hrs. After installed this, I hit 15 hrs normal use and 20hrs light usage. It controlled the CPU frequency and put my phone in very deep sleep. If I just make 1hrs of total calls and 20-30 text I can hit 20hrs easily. If I used Facebook heavily (65% screen on, about 3hrs total), I get 6-8hrs. Something is funky with your setup. During testing I uninstalled and reinstalled this app couple times and never any issue. Do me a favor while you're back to fresh stock, rooted and pop it back on see if it's working. I'm happy to provide screen shots if you don't believe me.
BTW, I have wifi,4g,gps on 24/7. While I'm in my house it automatically used wifi and when I'm out on the road it switched to 4g automatically. The samsung factory feature is working fine too.

Thanks for all the suggestions. I think I might give tweak stock a try
Sent from my MB870 using XDA App

The last few ROMs I tried, Tweakstock, Infinity, Gummy...all were very laggy. Didn't seem to matter what I did or how I did it. Camera was always a crap shoot on whether it would freeze up or not. I finally said the hell with it and went back to stock and then just plain rooted it. So far so good. It sucks cause I hate TW and the look of stock...but at least the phone is responsive.

Try Eclipse
You should really give Eclipse ROM a try. It is extremely smooth and fast....very responsive and the devs and community over at the site are very helpful if you run into problems. Yesterday, with light use, my phone was at 60% (15h 11m 25s on battery) at the end of the day. Best battery life I have ever gotten out of my Charge yet. Give it a try....you will not be disappointed.

Sounds more like something with the way you are flashing and/or your data restore. I would suggest that if you ever flash anything again you start from a totally clean slate
Charged up post!

I did flash from a clean slate multiple times, first few days the new builds seemed OK. After awhile it just got worse and worse. I've been on the rooted stock build for over two weeks and it still is pretty good. I'm done tweaking this phone, I'll have an upgrade option in May and then I will probably get the Nexus or wait a bit if something else worthwhile is coming soon.
