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
hey guys, I got a refurbished xoom the other day. it was kind of buggy. My android market crashes every time i try to download documentToGo and a couple of other apps. Sometimes the browser just keeps loading and loading and does not show a webpage at all. my web browser closes unexpectedly a couple of times today. It is slow to read pdf files. It is kinda frustrating.
Is this because my xoom is refurbished? Or you guys are all having this problems. Do you guys have any solution to that? Thanks.
It may be slow because it's refurbished, but that depends on the other problems. As far as the market goes, it's crap since the latest update, it closes on me a lot, it also gave me a problem with downloading docs to go, it wouldn't load the permissions so I could download. Some pdfs are slow depending on the content and the app being used to read it. Sounds like your problems are with apps and not the system, if the problems are bigger then I'd try to return it.
XOOOOOOOMIN!
i think u might try root it n flash a custom rom on it.
Mine is also factory refurbished (with one stuck pixel, how's that for QA) and mine was running somewhat slow until I flashed the Tachi kernel onto it. I'm debating flashing a new ROM, but at least a new kernel and an overclock will do you good, trust me.

Thanks for your advice. Would you mind give a link of the ROM?
I was running stock rom with both tachi and rogue kernels for a while...and it was a tad sluggish still.
Since then I have flashed moray and its been pretty awesome. Lots of extra functionality and the ability to use stock clocks for gpu while still overclocking is great. No lag at all.
OP you can find this ROM in Xoom development under Moray 2.2.2

I like the idea of this rom but I'm not sure I like some of the changes it makes (primarily with the battery icon and other small nitpicks.) Can I change these easily?
I had issues with my refurbished one lagging a lot even after overclocking until I reset the governor back to interactive. Also, the new rogue kernel helped with a few other lag issues I was having.

I've tried a few different ICS ROMS now and if they don't have battery life issues, they have home screen transition lag, app drawer lag, random reboots, screen flickering (like when it shuts off), app compatibility issues, etc... (some have all of those things, others just have one or two, you know what I mean) yet I always see a lot of posts in here about people praising X or Y ROM and somehow don't seem to have the same issues I have.
At first I wanted to call it an ID-10-T error on my part, but I'm doing full wipes and even using the wipe_all script on top of that, and this is my 5th or 6th Android phone, so it isn't like I lack experience flashing.
I've been using a stock, rooted 2.3.7 ROM + ADW EX and I'm in stability heaven. It's buttery smooth, no crashes, etc. I'm the kinda guy that'll go back to stock from a custom ROM the first time it gets laggy or randomly reboots. Stability and smoothness is everything to me. I really want to like ICS... but I don't have any good reason to force it upon myself right now if I can't find a stable ROM/kernel combination.
Anyhoo... what's the smoothest, most stable, ICS ROM for the Nexus S 4G? I expect to hear different opinions, but surely there would be some kind of consensus, right?
I'm looking for the same, and experiencing identical issues to you. I don't think it's an idiot error because as a result, but it seems to me that ICS roms have a long way to go in order to satisfy users like you and I.
The screen flicker appears to be a function of voodoo settings. I've tried a few kernels with no obvious differences, though I haven't messed w/ Voodoo as of yet. The lag seems to have been mitigated in entirety by using Launcher Pro instead of the ICS launcher, and general lag during homescreen and app drawer transition follows in the same path. OS lag, on the other hand, is much more obvious than in GB IMO.
It seems that the most stable/popular rom is oICSv43 paired with Eugene's kernel (ICUP). I'm using that kernel with CM9 (alpha19) by burnsra. Can't say I'm thrilled with it but I'll definitely be happy once this damn batch restore finishes without causing boot loops

Battery is great, the system is smooth. Very Very Stable. Everything works.Nothing is broken. Truly a pleasure to use.
The built in kernel is great but I used a newer version called ICUP 3.1.6
I'm just curious because I get a lot of mixed answers, some users claimed they never had a problem and their sidekick 4G runs smoothly while others say their phone freezes and reboots way too often. Some have also said installing custom rom has fixed their phone.
I have my sidekick since last may it does not freeze nor reboot constantly the most that ever really happen was that the screen got mosit so it stop working. I have had no more then 10 battery pulls were the phone froze. Generally I pull the battery when I need to turn it off quick. (Used gingerclone,lighting rev2,glorious overdose,

this question may perhaps be a bit tricky. some users, like myself, may have installed a custom rom, but that alone may not have fixed the lag. i installed b2tb, but still had a lag, and quadnrant score was the same before and after the flash. before b2tb, i was on stock firmware, and my quadrant score was in the 9s. after flashing, still in the 9s. screen lag was the same. a combination of voodoo lagfix and v6 supercharger have improved my quadrant scores to anywhere in the 11s or 12s. extremely little to no screen lag and no other noticeable performance lag at all. but simply flashing a custom rom did not fix my lag.
Try GenericGinger 2.0, I use it. I've never had my phone freeze, EVER. The speed is good, battery life great. Quadrant Standard score 1700+ google search it. I'm sure it won't be a waste of time

I have been using this phone for a month, and it seems everything runs smoothly. just the battery life, like other smart phones, is disappointing.
Way too often for me, I'm not gonna lie and say it never did, evn though I love this phone to death. Too bad the only beastly phone out there with a keyboard close to the sk's is on verizon.
Then again, I'm not sure what I do that makes it freeze a lot.

Have had my phone reboot due to running completely out of memory some cases an others just wtf why you reboot momments. Worst issue i had was dealing with a possible issue in the built in kernal drivers for the bluetooth talking with my kia souls bluetooth stereo cause it seamed now an then at work (pizza delivery) the phone wouldn't disconnect correctly an would cause other issues, like...... overheating x.X an it wasn't the battery cause the face of the phone was hotter then the back where the battery was an by hot i mean like almost hot enough to cause a burn x.x! Love the sidekick an if the devs can make a rom that patches every single issue the factory firmware has in it I'll very likely go back to it, but at this time I'm happy with my edge speed on my captivate (daily driver) an X10 mini pro (amazing backup phone that never fails )
Completly forgot sbout this one weird issus. One day, I magically lost root, had bto reflash to get it back, I have no idea how it could've happened because I wasn't messing aroun with anything.

I had some major issues yesterday with glorious overdose rom, I switched to gingerclone v2 and all is well now. Stock this phone is a turd....
I had to disable the trackpad today because in sunlight it would go hay wire and I wasn't able to browse online
is that what it is when i feel my screen going haywire? i'll be trying to text someone and then it keeps scrolling up the conversation and then trying to do a search throughout that convo...jeez i thought it was just a nasty bug haha i'll have to disable it then, i dont use it anyways...wish they would have brought back the trackball from the SKIII....now THAT trackball was cool.
I disabled it and now im not having issues with it. I get this annoying browser lag tho and I need to stop that. I am looking to get a different phone now. Im sure someone who is a heavy texter would love to have this phone...

Omg! This ROM is perfect! This is exactly what I've been looking for! I wish I could hit the thanks button a billion times!
4th Option
4th option - Factory Reset, Rooted, added App Killer and uninstalled most of the Bloatware (Like DriveSource)
works much better now, even with the Stock ROM.

Push PowerButton and Volume button [+ or -] at the same time for 10 seconds. This is a little faster & easier than a battery pull.
For a while I was using Ice Cream Sandwich v2.0 Domination with the ICS launcher removed and ADW launcher in its place. Everything was fine except for the Gallery. It would take forever to load picture, and occasionally, it would reboot my device if it took too long. I just switched to GenericGinger 2.0, and I've had no problems with crashes or reboots.
I'm running Gingerclone w/ Voodoo Lag Fix and V6 Supercharger Aggressive 2. Using Tegrak to OC up to 1.152 and I'm consistently pulling quadrant scores of 2200+.
On the stock ROM the phone froze and rebooted frequently. On GingerClone I haven't had it crash once yet.
***
Oh and I forgot to mention some things. First in Tegrak I set the CPU low limit to 200mhz and the governor to performance. Makes a HUGE difference in quadrant score and minimal effect on battery life.
Kj2 deodexed and rooted.
Stock browser, Gallery, and recently, Defender 2 cause it to lock up.
Stock browser and Gallery lock up less than on kg2 deodexed/rooted, but still do.
Gallery only on loading, and browser on scrolling.
I had that issue allot then I make it an effort to wipe the cache in recovery once per week, fixes its wagon for me. I also a running back to basics and dealing with the touchwiz launcher. Sacrificing looks in the name of this thing working properly is the name of the game.

Just wipe cache, or wipe cache and dalvik cache?
Welp, since i haven't posted more than 10 times I cannot post in the forum where this needs to be seen, but here it goes anyways. I'm running the most current build of Synergy ROM and noticed when I am in Google Earth, I seem to get ridiculous lag issues. I've been running Synergy since it became available on the VGS3 and haven't noticed any issues with it in the past. Does anyone else have lag issues in Google Earth while running Synergy?
I think it's just the app.... It's loading quite a bit of data. When after a location has rendered and you touch it, it has to re render things making it laggy again. Was is smooth before and you just updated and it's laggy now? I guess I've never seen it run 100% smooth ever.

Well I don't use the app often. But I feel like it ran a little smoother with the stock rom. I had actually just changed my clock frequency with No Frills CPU and had yet to reboot or anything. Seemed to run a little bit faster after the reboot.
