Nice try LG, but, it's not quite ready for prime time!

I've been through 2 G2x's , both have had the same problems...
Random reboots
Random freezes
Random shutdowns
Crazy inconsistencies in battery life
I've also gone the route of rooting and trying CyanogenMod with the same results.
With the battery issues, I did the following test 3 nights in a row.
Phone wiped, 100% battery charge, signed into Google and let the apps download, rebooted phone, data connection turned off (airplane mode), unplugged the phone and set in the exact same spot in the same room 3 nights in a row at 11PM.
Come 8AM when I woke here's the results:
Day 1: 30% battery remaining
Day 2: 80% battery remaining
Day 3: 0% remaining - battery was stone cold dead - wouldn't boot until I plugged in.
Phone was fine when I started typing this post, but just now while typing this message I reached over to check my phone for text messages (I keep the alerts volume all the way down while at work) and it's locked up again...
Guess I'll be returning the phone for a refund and borrowing an old flip phone for a month until the Sensation comes out.
Sorry LG - when it works, it works AWESOME, but I need something a bit more reliable considering that work needs to contact me on the phone and I am on call 24/7 !

In the 2 weeks I've had it I've only had 2 random freezes and no other issues at all. This is my first android phone and the thing i see that's screwed up with android is it leaves applications open, there is no exit buttons on apps. I've been using juice defender and uninstalling any apps that keep popping back up after ending task on them.

Sorry to hear about your problems. You're doing the right thing by returning it and getting another phone. I don't understand why people have loyalties to corporations who could give 2 craps about you. Buy what works for you and makes you happy.
For me, the occassional reboot on the G2X is a pain but the promise of a stable CM release and an official gingerbread release on this hardware has me sticking it out. Can't wait

I haven't had any issues with my phone except battery life. Buy my battery life isn't as bad as yours. It used to be horrible but I got a new sim and that seemed to make it better.
Regarding the reboots, some apps are causing the phone to reboot. Either the apps aren't optimized for the phone or the other way around. I had one reboot and after I removed the offending app, never happened again.

Actually, when I bought the phone I had them put a brand new SIM card as mine was getting to be a little long in the tooth - if getting a new one helps the situation I'd hate to see how it was with my old one :-D
Removing an offending app would prove to be a real problem for me though, as everything that I install has a legitimate work-related function.

im returning mine today for a newer batch one. its may 4 so i expect one that has the date of 4/24 and up as stated in other threads. mine reboots and freezes during random functions.

I ordered mine on the 20th so the day the phone was out in the store. I had to order mine online since i am a T-Mobile RSA. I have alittle screen bleed but not much. I will be doing exchanges until i get one with no bleed. Other wise i have had no problems at all. No reboots, lock ups, data problems, nothing the phone is rock solid. I love the phone. Every person that has come into my store with problems i have told them that T-Mobile is going to exchange this for you under the lifetime warranty if you have it for the life of you having the phone. So you have nothing to worry about. The phone is a great phone to have. Do the exchanges until you get a working one. I know i would do it until i did. Even if it meant doing it 100 times.

A better test would have been to not install any apps. Then you could truly test your phone and not some rogue app, that you keep installing.

I'm about to do a complete wipe again and use a secondary Gmail account I have so to eliminate any apps from auto-installing and test throughout the day since I have my work PC handy.

or just skip the Gmail sign in process at first and add your Gmail account later from Settings. This will prevent it downloading your apps on first boot.
Also to the New Android User: Back closes apps, Home leaves them open. It isn't the OS's fault if you don't know how to use it.
To the OP: Have you rooted and flashed the Pre-Dexopt Patch from Paul?
http://forum.xda-developers.com/showthread.php?t=1051616
LG left the phone in Dev mode and doesn't dexopt the phone on initial bootup. This is why our phones boot so quickly. The downfall is after a few hours, it starts to lag out and lock up/reboot.
Sounds exactly like the problem you are having.
This patch is required for stock and EaglesBlood Roms excluding CM7. This should be fixed in the upcoming Gingerbread update. I also believe EaglesBlood and future roms will start coming with this patch included.
So do yourself a favor and patch it.

Basically, it's an awesome phone and many, if not all, of the issues should be resolved with software updates. Gingerbread is already in the works.

Yep, have tried without the patch initially and then with it.
I have signed in with the secondary Gmail account - only thing I imported from the original was my contacts, so, it's 100% stock with the exception of Paul's patch and recovery.

I'll be damned...
In an attempt to preemptively find out what I would need to return the accessories I ordered for the phone just in case I took the plunge and returned the phone, I was on hold with T-Mobile...
And while on hold, I grabbed my phone - and SURE ENOUGH - LOCKED UP HARD!
So, I guess this just made up my mind for me - I'll be returning this phone to point of purchase. Just need to use NAND to restore the stock backup , reflash stock recovery and unroot...

I am planing to return this phone too..
It seems the phone shut down completely for no reason, sometimes the screen doesn't wake up even tho phone is running in background.
So far i have tried to run completely stock with no apps installed no sync nothing and i was getting battery like 6-7 hrs.
I guess that was not acceptable for me.
I might have to wait till HTC Sensation comes out. What you think guys ?

Mine works fine, no problems at all, yes the screen bleeds a bit, but I can deal with that.
awesome phone, much better than my atrix

That's where my money is going...

my understanding is the sensation is locked down that's why cyan isn't going to get it. Which also means no dev support.

The MyTouch 4G and G2 were locked down too... Unless they are going to lock the bootloader?

HTC announced an update to the Sensation in Q3 that will include a NFC chip to match the features of the SGS2. I'm also guessing they'll increase the amount of RAM in the phone to make it more competitive. If the 2.3.3 update makes the G2X stable I may keep it until later in the year. If the Sensation comes out before they update the G2X I'll get Sensation. I need a phone that's consistently dependable and in that regard the G2X is a mess. I can't do custom ROMs because I travel globally and everyone I've ever used has always given me problems registering on foreign networks so CM7 is no silver bullet for me. It's a shame too because the G2X hardware (bleeding screen excepted) is pretty slick and it's really fast when the planets line up and everything works. Sigh.

Phone won't boot until battery is pulled/re-installed. Why??

For some reason my phone just started having an issue where once it is turned off, even with battery charge remaining, it will not turn back on until i pull the battery and put it back in.
I figured it may have something to do with the custom ROM so I tried loading the backup of my stock ROM and the problem still persists.
Is anyone else having this issue?

I also have this problem...started the thread here http://forum.xda-developers.com/showthread.php?t=1154433
There are other few people who have stated the same with them too.
I went to the service center yesterday and they told me its the faulty battery and new battery is on its way... BUT they are blatantly lying..because before using the stock battery i had used TWO chichitec and then also the same problem occurred...so i went back to the stock battery thinking maybe these extended batteries are fake...however after 15 days the same thing happened with stock.
I am using stock ROM with S-off...no hanky panky stuff to let them say that i violated anything.
I think its a hardware issue which they are refusing to accept at present. Maybe when the new battery faults then they would check the same.
Sometimes it is very frustrating and embarrassing also.

Thanks for the reply. I knew I couldn't be the only one with this issue. Luckily I turn my phone off once every couple weeks so it really isn't a huge deal to me. But between this and the touch screen acting up I'm really starting to miss my rock solid MT4G.

Just an update. After switching to the Senseless Extreme rom my phone seems to have fixed itself.

Have you tried flashing back to stock and seeing if the issue is resolved still? Maybe it was a corruption issue.
Although if you like Senseless then just stick with that.

I am on stock but still facing this problem...I doubt this is related to software somehow...Otherwise on pressing the power button the phone would have restarted... I sincerely believe this to be a hardware glitch because the power completely shuts down and the current stops flowing from the battery to the hardware.. For me it happens sometimes in 20 days and sometimes (very recently) happened on two consecutive days.
I have also ordered another SIM (of same carrier) just to rule out that possibility also that my SIM card is old (have been using it for 7 years now)

Hm, keep me posted on what you find out. Mine seems to be just fine for now. But I'll see if the problem returns in a few days.
And, Termic - I am loving the senseless rom. I forgot how much I love pure Gingerbread. I'll be sticking with this one for sure.

You are right, it is a hardware problem, I solved it by buying another battery. Everything is perfect now.
P.S. get a higher mAh battery, I got Anker and I'm very happy with

Buddy have tried Chichitec batteries and then also had the same problem...AND not one but TWO Chichtec batteries... both same result...

[Q] Phone shuts down?

My sensation has a very bad habit and I would like to ask you guys if you know why it is happening..
My phone shuts down about once a day and then when it is turned back on the battery has dropped about 20 - 35 %.
I have taken few screen shoots of the battery level and they are attached with this thread.
Im not using any other ROMs or anything like that. I have taken about Juice Defender which I used for about 2 weeks.
I know three others Sensation users and they have never experienced something like this.
I have asked the sales people and the technical people and they have no idea and say that this is prob some app that I have put on but I havent put anything on it that can mess this up.
Any solutions ?????

wow, I've never seen any android phone do that, have you tried restoring to factory settings and then trying it out?
It could also be something HTC needs to fix on your particular phone, so I might contact them about it.

First I wanted to ask if someone knows the answer to this but if I dont get any answers I will do that and see what will happen.

Try uninstall juice defender. I had it last time for 3 days. Nothing it do unless harm my mobile data 3G connection connect & disconnect & battery life goes crazy up & down!!
Sent from my HTC Sensation Z710e using XDA App

juice defender is not for gingerbread devices

yeah i agree i think your best bet would be to uninstall any apps that have to do with the battery and see what that does.
if that doesnt work restore it

I have uninstalled everything and i did that before all the images that I attached above. I have over 10 pic like the once above.
Thanks for the advice I will wait a little bit longer before restoring it.

Does it a shut down or a restart?
if it shuts down, so that you must press the power button to turn it on again, it's the same problem i had, and maybe still having...
This problem became stronger and stronger (did shut down 4-5 times a day at the end, but always with "low" battery, <65%)
I've returned my device to HTC and they sent it back with no failures found
after 3 days the problem appeared again. Then i bought a new battery (a original one), since then phone didn't shut down except one time, but that could have been the new kernel i flashed . So I'm very confidently that this was the failure.

My phone shuts of and does not restart. So I guess it might be the same fault as you had.

Yes I would take it back and demand for a new one or you can contact HTC and they will charge oh about $250. But first contact tmo customer service first and see if they will replace it with a new one that way you won't have to pay $250 to htc . Your sensation shouldn't be rebooting on its own oh by the way make sure you demand a replacement they may try to get get out of it good luck

I had the same problem, I recalibrated the battery 3 times one after another (is it english? lol). The problem has improved but continued.
So I tried that [MOD] Battery jumping and accurate reading Fix 2.3.x.
Since I had the problem that 2 or 3 times in 2 weeks.
If I buy a new battery does it will fix it?
(Sorry for my bad english!)

I have the same problem too. I tried everything. I tried factory reset , flashing new roms, talking with htc but i cant fix this. It still randomly turns off. I think only new battery can solve this. One guy said that he buys new battery and 1 month passed still have no problem. So i ordered anker battery. I hope new battery solve this...

I have a theory here.
Difference kernel will give difference control and usage of current and voltage signal. Therefore if you are using wrong kernel for a long time, maybe it will damage the hw especially small small ic which very sensitive and cause it to malfuction which cause shutdown or restart and in the end burn etc.
Just my 2 cent and please ignore me if im wrong.

Ok now your talking what kernel are you useing I'm useing a faux kernel v2.6.35.14-bricked -v1.2-gpuoc [email protected]#6 and lve had know problem's fast smooth you should check it out you can't go wrong with a faux kernel

Phone randomly shuts down

Everything was fine on the phone until I tried out AOKP 4.2.2 alpha 2 a week ago, When I had the rom installed the phone would randomly shut down. I thought it was because the rom was not stable enough so I flashed CM9. On CM9 the phone would shut off every five minutes it was that bad. I then installed Miktouch 0.7 and the shutdowns for the most part stopped. The phone will shut down now and again and it always shuts down after I use youtube for 10+ minutes or use the camera for several minutes.
I tried to revert to stock and see if that fixed anything but when I boot into the bootloader it looks for PG59IMG and says no image found and nothing happens. I got the PG59IMG from this thread: http://forum.xda-developers.com/showthread.php?t=1878329
Any help is appreciated.

I swear it sounds mechanical...maybe battery related. Just starting out of the blue like that and it being cross ROM and all. It should just flash that file automatically from hboot though. Are you sure you copied the file to the root of your SD card? Did you relock your bootloader with *fastboot oem lock* before running it? Sometimes it doesn't like it if the usb cable is still plugged in. (for some weird reason) If you're still S-On, did you flast the boot.img file thru adb with *fastboot flash boot boot.img* after flashing your ROM?
Oh yeah, you won't be able to flash that PG59IMG if it is newer than the hboot version listed in your bootloader right now. That is until you get S-Off with the wire trick.
Check some of that stuff out & get back to us.

I agree it sounds mechanical, most likely a bad battery.
I confronted similar behavior over the weekend and a testing with a new battery allowed me to point a finger at an older, aftermarket battery as causing the shutdowns.

Sorry for the delay in the reply - real life got in the way.
I thought it was also mechanical but the shut downs are MUCH less frequent in Miktouch than on ICS roms so I thought it may have to do partially with the software.
I'm S-off, used the revolutionary method years ago. Never issued the "fastboot oem lock" command and I've never done anything related to fastboot. The stock image was in the root of the sd card.
When the phone does shut down it doesn't matter if take out the battery or do anything else, I can't get the phone to start back up until 20 mins later or so. The phone will certainly shut down if I use the camera or use youtube so if there is a way I can grab a log or something that could help let me know

I've had very similar issues, since installing a CM 10 alpha, and now on 10.1. The first couple weeks when I first rooted/flashed CM 10 were fine, but then it started rebooting one day, and never has stopped. Stock battery, no reboots prior to that, S-On, flashed the boot.img for each rom, and it's doing this with both CM 10 and CM 10.1. Does that also sound like battery, since it's the stock battery which has always worked fine? Also, it seems heat/intensity related - if I'm playing a game, using GPS, or talking a long time, that's when it tends to happen, and then it tends to happen right at/near the lock screen for a while after that until it's cooled down (perhaps that screams battery, but since it always restarts fine/has power I would have guessed it had to do with the processor or kernel). Thanks in advance for any advice!

Could be the battery...
I agree with the other posters. I had the experience of lots of random reboots a while back when I was working my way through sverhagen's 9.1r3+ ROMs. But, it just turned out that my stock battery had given up the ghost. Swapping to one of the gold batteries fixed the problem. I tried the stock battery in the interim for a brief stint and switched back to the gold, as the stock battery still caused random reboots. So maybe its time for a battery refresher

Yeah....the little suckers are on a power trip I think.

i've been having some shut down issues for a while, on different ROMs so I don't think it's that. whenever i'm using it i don't have any issues (unless it's a known ROM thing, that's separate). even during the day when i'm not using it, it hasn't shut down or anything. the issue is that a lot of times when i wake up, i find that the phone has been shut down. i charge it overnight. so, my best guess is that i should stop doing that, maybe the battery is bad, it can't handle that for that long?
idk any ideas would be helpful. i'm considering buying a gold battery anyway

Did you try the new Battery ?
I was have random shutdown and lockup problems. The phone would lock with a blank screen and I'd have to pull the battery to get it back.
Am running SilverL's CM 10.1. I might be a coincidence, but I backed off on the aggressiveness of the CPU settings (in the performance menu) and the problem went away.
I'm currently running a min/max = 128/1242.

I'm trying not to post a new thread so I'll post my very similar problem.
I got this phone about a year ago. I put Miktouch on it and was experiencing random shut downs all the time. I believe I posted on here and I can't remember the responses. As the mytouch q kinda sucks and I want a solid phone. I gave it another attempt this time with CM 9.1.0. When I used the camera once it shut down and restarted I think. Then I got a solid few days before it started going wanky again. Today alone I've had like 5 restarts. From what I've searched around it seems the problem here is the battery? This is stock battery and I got the phone used off ebay. I think I used stock rom like a week before rooting and putting Miktouch on it.
edit: For some odd reason my background also changed. Charged the phone backup. It turned off again.

If you've flashed any ROMs here to the MyTouch Q then that's your problem. It isn't this phone. These forums are for the HTC MyTouch 4G Slide. A much more powerful phone with a different manufacturer & motherboard. If you have S-Off go to their forums, wipe...wipe...wipe & reflash one of their ROMs. You're lucky you're not bricked.

I know. I'm talking about two different phones in the same post. I bought this phone (Mytouch 4g Slide) last summer but shortly started having problems. As I didn't want to deal with it I went back to my slowly dying touchscreen on my G2. When that finally died (touchscreen) I just bought a mytouch q as I wanted a phone that worked. This was my first new phone in a long time.
I am NOT trying to install any roms for the MyTouch Q on the MT4GS or the other way around.
S-OFF should be off on the 4G slide. Pretty sure my mytouch Q is still rooted though. It sucked at running CM 9

Sorry. Somehow I got confused. That being the case, it sure does sound like some type of a hardware issue instead of a software one.

Yeah, from what I read it could be a battery problem. Going to go with this Anker battery as its the only reliable battery I can find that doesn't cost an arm and a leg.
Anker Battery

Yeah I'd start with a new battery myself, either a new OEM or an anker, both are cheap on eBay. Also look for a post where me and weekends were discussing the emmc of this phone, bear in mind I have zero proof, but I got a suspicion there may be multiples they put in here and some worse than others.
If the battery won't work then I would repartition the whole dang thing, either by returning to stock and the rerooting and resoff, or by at least flashing the same bootloader on top of the one you currently have.
Just some ideas, but if you want a better idea of what's causing your issue, pull a logcat

I have a theory of whats causing it. If I extensively use the phone the battery warms up which gets to the point it shuts down. Thus if the battery is still too warm and I turn the phone on then it will just keep shutting down. Of course I can't do this until I'm home for the day as I'm out and about this weekend.
edit:
I used the Revolutionary way to turn s-off which is permanent.

I get random shut downs constantly. Usually atleast 3-4 times a day. It's pretty nerve racking. I honestly don't think it's the battery, I've experienced this issue on three different batteries and it happened on all of them. It's not ROM related either as I've tried probably 15 different ROMs (stock based, ICS, JB) and they all have this issue.
My buddy who has a Sensation also has this issue on his phone. Maybe it's a problem for that phone too since they are pretty similar?

Odd Battery Problem

OK I HAVE searched the forums, but it seems this is a combination of a bad battery and/or the sudden death problem, however, the phone is less than 6 months old, the problems have all of a sudden appeared and I was able to get the phone back up an running so now I don't know what to think.
In the past week, I have noticed my GS3 just completely shuts off without warning even though it displays the battery at about 20%. When I plug it in and restart the phone, it shows 0% and charging. This has happened about 5 times now in the past week or so. Today, it happened again, but I was in the car. I tried to use my friend's car charger and it didn't seem to work. The phone kept buzzing like it wanted to turn on or charge but it wouldn't. I got home after a few hours and plugged it in. I tried to start it and it got past the SAMSUNG screenand then to the splash screen but it hung at the splash screen and would not boot up. I tried several times to boot, did a battery pull, even wipes the caches. No luck. Finally I went into recovery and did a complete wipe and restored a backup from March. I got the phone back up and running and all my apps are updated.
Does this make any sense?
Why all of a sudden would the phone misrepresent the battery life at 20% when its 0%?
Why would this 20% issue only start this week?
Why would the phone not even be able to boot up after going to 0%?
A bad battery seems unlikely since the phone is less than six months old and the sudden death issue is unlikely because I was able to restore with a recovery backup.
Any help would be appreciated. I am running Synergy ROM Nightly JB (r169) and the kernel is [email protected] #011013 from January 10, 2013.
Thanks,
Jim

Phone maybe not reading battery correctly? If it happens again, I would try wiping battery stats in recovery

Hi thanks for the reply, but I'm pretty sure wiping the battery stats doesn't actually do anything. I'm not sure why there would be the option to do it in the first place but most battery issue posts in the forums indicate that wiping battery stats is a falacy.
Thanks anyway,
Jim

deleting batterystats.bin fixed this problem for me. it wont hurt your phone.
I charged to 100%, deleted batterystats.bin, drained to 0%, charged up to 100%, never had the issue again.
youre right it doenst improve anythign battery life or anythig, but it can still fix problems.

Out of curiosity, why are you still on 169?
443 is out, and running real nice
With that being said, if this is an OEM battery (or if it's not,) it could be that the battery is the issue.
I always have a couple of spare OEM batteries on hand for extra juice if the need arises, and they come in handy if I ever have to isolate a battery issue.
You can always pick one up for about $20, and see if it is your original battery which is the culprit.
Btw, here is pretty much the gold standard on batteries.
It is an excellent reference, makes for some good reading, and can come in handy
It includes a whole lotta info on Lithium ion batteries, which is the chemistry used in modern cell phones/smartphones, and a lot of other applications.

OK I'll check it out. I am still on 169 because it works and I didn't want to fiddle around with it too much. I looked at the new features and there really isn't anything I'm missing. Also, I have Google Wallet working well without any issues and I did not want to screw up Wallet by upgrading. I'm waiting for 4.2 to come out with Touch Wiz (I actually like TW) and then I will upgrade... unless there is a new feature I'm not aware of?

Regarding any new features in SynergyROM r443, I would recommend reading the Changelog here, as there's been a few

If I do a dirty install, will Google Wallet remain or would I need to disable my Wallet account, and then go thru the whole install process again?

hmmm. the download for R443 doesn't seem to be working... I just get a spinning circle after the mirror link appears but the download never starts. I guess I'll try it again later.
