[Could be my phone only] This phone has some serious problems!!! :(

Phone was fine, sleeping. Tried waking up and nothing. Tried again nothing. So I figured crap it's shut itself off and won't turn on. So battery pull and turned it back on. Then boom! Get's to the T-Mobile G2X logo and then just freezes there. WTF???
For a while I thought that was it, I pulled battery yet again.
Turned back on and now it booted up ok. WTF is going on with this? I've never seen these type of issues with other phones. What could cause this? Almost seems like a hardware issue because I used it all day today for about 10h with no issues.
So I got the phone at 4PM yesterday.
- Worked fine from 4PM - 11PM. I rebooted myself. Started up fine and then rebooted at 11:30PM
- Worked fine rest of night and went to bed at 2AM...was charging all night, woke up and used it fine. 8:30AM rebooted.
- Used it all day at work and no issue. Was using it while walking the dog at like 6PMish and boom reboot.
- Used it since 6PM and then it just did the hard lock/screen off thing that required 2 battery pulls to revive it.
Before this last what is essentially a crash, I had GPS turned off so that didn't help. I've turned it back on.
In all these situations I had WiFi calling enabled so I'm now trying with WiFi calling disabled and see if I still have issues.
I'm giving this phone a week because I love it so much but if I can't get it stable it's going back and I'll have to go back to VZW and my Incredible. Major bummer

Have none of those issues. Might have a defective phone. And u were a verizon customer and didn't get the TB? Verizon LTE blows everyone... way faster than Tmo.. I have both lol so I know what I'm talking. G2x faster tho but TB faster network. Downloads and browsing

Ummm... I got 12Mbps on MyTouch4G on T-Mo's network - my buddy has the TB and has yet to pass 9. If this phone had HSPA+ 21, I imagine I'd be able to eek out 17 or 18 on T-Mo.
Anyway yeah I don't have any issues with mine other than things that were my own stupidity (skipping the Google login and trying to set it up later which broke wifi calling and market access over wifi and required a factory reset to fix). Its an amazing device!

Yeah, I'm all clean here too. I'm not experiencing anything negative and been using the phone all day. Fantastic device, glad I got it.

Sounds like you got a lemon and need to try another before you trash it s having serious problems.....
Try again there's always bad ones out the batch.

on my tb i hit 16-even 20mbps lol i haven't touch over 8mbps on my g2x yet and upload speeds are much better with verizon

Those of you not having problems. Are you all using Wifi calling? Do you have network mode to auto, GSM or wcdma?
CNN just updated their app so maybe that'll help me if that was the culprit.

I have a Xoom on Verizon that will soon get LTE and I'll use as a hotspots so I don't really need a VZ phone.

I also have the thunderbolt and the nexus s and I previously owned the mytouch 4g. And verizon 4g is spectacular to say the least. I have downloads speeds as high as 20mbs on a consistent basis. Tmobile can not compete with verizon service. But tmobile does offer a great value, and has stellar customer service.

Meh, idk. I use both and while Verizon 4g is currently fast, not always faster, that wont last. On 3g, Verizon is much slower.

Maybe you could edit the title to say "My Phone" even though some others share your grief. It would appear not all does. .....thus far.

And if T-Mobile had gone with a better chipset (21-42Mbps instead of the same 14.4 that the G2 has - mind you the Vibrant 4G has 21Mbps HSPA and my buddy regularly gets similar speeds to yours - 17-19 down and about 2.4 up) for the baseband, it would be a non-issue. T-Mobile has a smaller network and thus more backhaul than Verizon. Also, using the AWS band, T-Mobile can support more calls and data connections per tower than Verizon can on the 700 band. Its just the way that the spectrum works. 700MHz broadcasts further but can't handle as many connections as 1700 can but 1700 requires more towers for sufficient coverage but has over twice the total network capacity as 700. That said, Verizon being an ISP as well gives them a backhaul advantage.
As was previously stated though, do not expect the speeds on Verizon to last. Also keep in mind that Verizon is quite like Sprint at this point - you have to have LTE *AND* CDMA turned on to make and receive calls and still get your 4G data. This equals much higher battery drain than an equivalent "HSPA+" phone on T-Mobile with the same signal strength being taken into account.
Anyway, as was said earlier in the thread, don't give up on the phone. Try a factory reset first (settings/privacy) and set everything back up again - if that does not work, exchange the device. I've had no issues outside of my own doing with the G2x yet which is amazing since I almost never buy the first generation of a device due to bugs. LG really makes high end android phones.

I had installed the Car Home from the Market by sending to the phone via bt. After looking at my usage in spare parts it looks like it was using some sensor all the time so I'm hoping that was the issue. IV uninstalled it and closed the current car home app that's included. So far no sensor usage. Lets hope that fixes it. Would make sense because I doubt other folks installed this Car Home app on their phones.

I'm also having similar issues with my phone. I received the phone yesterday morning and i've got nothing while trying to wake it up a few times. It's happened about 5-6 times and it seemed to happen while charging the phone. I don't know if that is a coincidence though. I pull the battery and then it will boot up fine. I actually had the same issue with my original G1. The issue went away after the phone received a few updates.

This. Wait until more than a few Verizon customers are on the 4G network, speeds will drop a bunch. LTE will probably still beat out T-Mobile's 4G, but not by much once the network gets some traffic. As it stands, Verizon only has one 4G phone that is pretty new, so I'm sure the total number of 4G users is quite low.

I'm definitely jinxing myself but....since I removed the Car Home app and then rebooted. Then stopped the Car Home app that came with the phone from running. It's been OK. Battery life is better too. If I can get it to last at least 5 days before a reboot, might be livable until an update comes along.

I am still pretty disappointed in this. I can't figure out why T-Mobile downgraded their latest phones (Sensation and G2x) to 14.4 from the 21 of the Vibrant 4G. This is supposed to be their flagship phone, but they didn't even put their best modem in it, yet the Sidekick 4G got a 21Mbps modem? Just don't get it.

**** **** ****! Sorry...just happened again. Reboot. Bam. This is irritating to the extreme. Wifi was off, BT was off, phone had been fine all morning. Was exchanging texts with people and put the phone down. Next thing I see, it's rebooting.
WTF!!!!!!!!!
Maybe it's an app that's running but just seems very random.

I believe this has nothing to do with tmobile. the reason why the galaxy s and sidekick support 21mb/s is because the hummingbird processor supports it while the snapdragon and nvidia only support 14.4 mb/s

This doesn't seem so random anymore, and I've read about all the same issues with the O2X. Are you going to try to exchange it before making a final decision?

Help ! G2X - Poor Reception ? Anyone Else ?

Just got the G2X today.
I'm having extremely poor to no reception at work.
All TMO phones I've used (G1, G2, N1, NS, Mytouch, Mytouch 4G, Galaxy S 4G)
in the past have random reception problems, mostly what I'd say is passable reception at work (in and out of steel buildings).
This G2X is the worst yet.
TMO service walked me thru putting a new sim in and and all.
But it didnt help.
It jumps back and forth from 2G with 2 bars to no service at all.
I didnt like the Galaxy S 4G but it got better reception.
I like this phone, vanilla and all.
Anyone else having this issue ?
If not its going back to TMO.

I got mine this morning at 10 and I have been having great reception! 4 bars with the 4G! And I came from the Samsung 4g also!

How do you know if you got 4G, I got the 4G symbol but network connection says utms and I mainly get around 3mb download on speedtest, but sometimes it goes to 7 or 8 mb down...but still says utms, I thought that was 3G. thanks!

I have had great reception with the G2X. Better than both the G2 and MT4G.
fhaines

I love the phone, but the reception isn't very good in my house. The nexus s had better reception.
Sent from my LG-P999 using XDA App

G2x's reception is on average about 5 to 10 dB weaker than the MT4G that its replacing but I have full coverage everywhere I go and at home I just use wifi calling so its a non-issue.
I live right by an air force base and I'm sure their signals interfere with cell reception. at&t has tons of towers out here and I had to switch because of the signal interference being so bad.

I still have the MyTouch 4G and Galaxy S 4G and they both have much better
reception than the G2X does.
I'm pretty disappointed.
I'll probably end up returning it and going back to the MyTouch 4G
(I didnt care for the Galaxy S 4G....200mb internal memory what ?).
Especially since its being reported the Sensation is hitting beginning of June.

There are like 6 or 7 "poor reception" threads in here.
Does that mean this is now definitely a known issue ?
All I got was them walking me thru putting in a new sim.
Nothing improved and the tech said oh well it must be just the area you are in.
And this was after me telling her the MyTouch 4G and the Galaxy S 4G didnt
behave in this manner !
I'm leaning towards returning the phone at this point, but I'm going to wait
a week or so and see if any software updates addressing this are forthcoming.

I had a great reception with my G2x. Had 4G throughout the day both at home and office. And on the way from between home and office too.
Unfortunately had to return it for reboot issues.

I am getting only umts. The device shows 4G but still only umts. I have installed new sim card and had it reset on the network and nothing changes. Even my Vibrant will show hspda when in 3g areas but not this phone so far. I have called CS 3 times and finally they have agreed to send out a replacement phone. I also have had random reboots ( it reboots but reboots right back up to the app you were running before the reboot.) and after speaking for only apporx. a minute the phone feels like it will burn your ear., I really want to keep this phone but if the replacement is the same than I will just send it back and wait for the SGS II or the Sensation. Really is a shame as there is so much I really like about it.

Got the phone, what gives. Connectivity sux, shows like 3 bars and 4g but the internet is slow and spotty. What gives? My HD2 runs just fine in the same spot.

I'm not getting any signal issues. My signal has been working great. I'd say return it man and get another one.

No 3G At All ! Whats Up With That ?
Definitely has an issue.
I've never seen it get 3G on this phone.
Only 2G or 4G.
I guess I will be returning the phone.
I really hate to, I like the phone.
But there is definitely something wrong with it.

My G2X has the best signal I have ever had with a T-Mobile phone. I keep a data signal in more places than I did with my Vibrant.

My signal is great, but I'm only seeing 2G or 4G. This does not surprise me, I'm in a HSPA+ area. Why would I ever see 3G?

I can't take the reception jumping from full 4G down to 2G constantly. I ordered the Nexus S and I'm not looking back. Even without support for 14.4, SAMOLED and better service will make up for it.

FWIW, I came from a Nexus S and think the reception is quite a bit better with the G2X.

If you have reception problems you can try 2 things:
1) Go into your mobile network settings and change your network mode to GSM/WCDMA if it isn't already selected. Then click on network operators and do a search. You should see T-Mobile UMTS, T-Mobile GSM and ATT GSM. Once you see the networks it finds, click on select automatically. Before leaving this menu, make sure you click on data roaming. Don't worry, you won't be charged unless your internationally roaming.
2) Swap out your SIM card.

Did all that the 1st day (4-20-11).
Finally returned the phone today after testing the data connectivity
at work today with the MyTouch 4G versus the G2X.
No problem with the MT4G but the G2X had horrible or zero internet.
I will post the results with a new phone tomorrow.
The rep said they just got in a new batch of phones.
I hope the exchange has fixed the issue.
Its mostly wifi hotspotting that its really evident.
I want the phone to work because its the snappiest phone I've ever used.

Maybe it could be the area you are in. Both of my G2x and G2 have solid 4g signal.

Have to turn off mobile data 2-3 times a day

I have had internet connectivity issues that get cleared up immediatley after i disable mobile data and then re-enable.
It happens when i am in a solid 4g area sitting in the same place surfing the web and my data will just die. and it comes back right up after i disable and re-enable my mobile data.
it also happens when im on the bus going back and forth between 3g and 4g.
is this a normal droid charge issue?
seems like it craps out after about 10 min of surfing every time i remember it happening.
i had this happen when i was stock, after i rooted stock, and now on tweek 2.0

Had that issue yesterday on 4G, and it cleared up the same evening. Occasionally will lose data connectivity on 4G, even with it's still showing the connection. It's not very frequent or consistent, and it seems to have gotten better over time. There is definitely some flakiness on the radios on the Charge. A friend was sitting right next to me on his Spectrum yesterday and wasn't having any issues. I think it's likely related to Verizon network, but I think some phones are more sensitive to it than others.

Yeah, happens to me too. I had to disable/re-enable data at least twice today. :/

hmm.. i did have a few sim issues when i got the phone a week ago, after loading a rom the phone said there was no sim inserted or there was a sim error cant remember which.
maybe swap the sim tomorrow to see if that helps.
sounds like it might be a charge radio issue... i am getting what ever killer phone comes out in a few months anyway. Galaxy s3? HTC one X ? Galaxy Journal ?
Motorola hd ?

re
So i got a new sim..
Nothing has changed.
I have netflix and live in a great 4g area and still have to toggle off data 2-3 times a morning on my bus trip into seattle.
It seems like the radio has a hard time figuring out wtf to do once it comes in and out of 4g. I can be sitting at in traffic for 5 min with no signal and flipping the data on and then off... BAM 4g is back.
This makes for annoying netflix / IT Crowd, viewing.
I am glad that i got this phone as a temp solution cheap from craigslist. Motorola Droid fighter or Galaxy S3 will be putting this lump of mediocre electronics to rest in the next month or so.

What radio is installed on your phone? To find this out go to settings/about phone. The baseband version would be your radio. If it says i510.06V.FP1, that means you are on the most up to date radio. I had similar issues before I updated to FP1 but since then, the 3 or 4G has been very quick to connect and stays reliable all day.

One of my buds works for Vzw and he told me that the 4g network is great when it works. In some places vzw is activating 4g network before the network is ready to be deployed. They are doing this because competition has more 4g coverage.
One solution is to set your phone to 3g only and accept reliable slow sppeds or deal with crappy 4g. Eventually vzw will get it right. Wjen though, is anybody's guess.

Those with signal issues

I was having signal issues in areas with less then 3 bars for the most part. Sometimes I would randomly lose service for a few seconds here and there. My calls where dropped or the caller would cut in and out during the conversation. If your having similar issues then your phone is most likely defective.
I just got a refurbished SGS3 from Verizon and the radio works flawless compared to my VRALF2 purchased in July. I would suggest calling Verizon and complaining if your having similar problems because my phone was defective.

Software problems

Not sure how you can conclude it was your phone. Unless you tried the new radio on your old phone before swapping. Otherwise you are comparing apples to oranges.

No actually Hardware problem, most likely the radio itself.

Ive been around the block here at xda so i know phone software and flashing. Software wise I tried it all.

I'm glad these radio issues haven't plagued the vzw sgs3 like they have the vzw gnex. Getting my S3 tomorrow. Hoping I get a good one, but my chances are way better with this phone than doing the refurb constant receive and send back like my g/f's Gnex. She went through 3 with radio issues before we got a good one.

I'm guessing it just a quality control issue. My girlfriend has the Moto Razor which has an great radio in it and she never had signal issues. I was beginning to think that the radio in the GS3 was just terrible. After some time with this new phone its right on par with the razor as far as call quality. Her razor still has the slight edge when it comes to signal strength.

Moto will always have the edge for the forseeable future on radio quality/reception. (notwithstanding the bionic....lol (but that was software IMHO)).
My razr's always had a better signal than any Sammy phone I've had. My HTC radios have always been pretty good also. Lets face it, Samsung's radios are their weakest link IMHO.

I'm new here, so first of all: Hi Guys!!!
I got some Issues with the radio, too. So I tried some different baseband versions with nearly no result
I currently use the LH1 baseband. Since some days I own 2 SIM's from 2 different Providers (Vodafone & T-Mobile).
Unfortunatly I only have an old Nokia N97 for Comparsion, but that doesnt matter atm.
What I've tried to figure out was, whats the source for this Issue - the phone, the provider or the baseband.
Well, I tried both SIM's in both devices and tried a few basebands for the SGS3, with the result that I got a little better Signal with Vodafone SIM and LH1-basband, than with the same baseband and T-Mobile SIM.
T-Mobile: about -105dBm
Vodafone: about -95dBm
The Signal-Strengh on the N97 is nearly identic with both SIM's.
So my final result is:
Baseband on the SGS3 sucks but can be changed to may get some better signal strengh specific for each provider!
Lets wait what official JB will change.

I just got my galaxy and where i live its a really hard to get signal area, but i have own the rezound , regular razr n maxx , galaxy nexus , and the lg and all get good service just tried this galaxy where i live at and lost 2 drop calls and text messages come as errors and thats in stock within.

Its probably a little early to tell. I had my phone for 30 days before i ruled out everything but the phone itself. But I had those exact problems with mine as well.
Things that i checked for right away.
Network/Tower issue
4G Sim card
Different modem software ( I tried all 3)
Factory Reset
Different Kernels

I am on my forth Galaxy S3 for call and data dropping. I use my phone mostly at the same 2 locations, work and home and my data drops constantly on all 4 phones. I have had the sim replaced twice. I have 4 lines on my account one of which is a Droid Razr which was handed down to my girlfriend. I can't recall ever having a dropped call or data with that phone. We were in the Vons grocery store Sunday and we both wanted to d/l the Vons app. It took her less than a minutes on the Razr. It took me almost 19 min and the app is less than 2mb. My phone is still stock. Its a beautiful phone but I'm really starting to hate it.

Maybe I spoke too soon about radios not plaguing this phone. LOL.
Get mine today. I'll have an iphone 4s and gnex to compare dBm and asu numbers. (Scratch that....can't find that info on the iphone (g/f's phone)) (found how to do it....not messing with it while she's using it)
Right now my Gnex is at -87 dBm and 53 asu and I am in a very strong 4G area.

Yeah im having dropped call issues then the phone says lost service and then no sim card detected then new sim card detected and then it gets signal back. The messages the phone displays are not exactly what i stated but similar. I talked to some vzw rep on the phone and she said that i am on the edge of the 4g service area. And that 4g is fairly new where I live. Should that affect my calls though?
Btw i had a htc incredible 1 and it never gave me those issues...i feel as though the speakers were better on the incredible too.

Just keep calling back. Tell them you stayed at a friends house that has great 4G service for a few days or something similar. They gave me the same excuses. What helped me is that there are two other people in the house on the same plan that have 4G phones and they haven't dropped any calls. You have to be persistent and almost demand what you want sometimes but do it as nice and respectful as possible.

well i'll post the other side of this....I had horrible signal issues, tried replacing SIM, no luck. got new phone sent out, same problem. Coming form galaxy nexus with no probs. Calls drop, drop only parts of audio then come back etc. I am in the same places I have been for the past 6 or so years and never had problems until this phone. Can't get signal in my basement or my office, neither of which haev been a problem in the past. so if a new phone fixed it for you, consider yourself lucky.
btw what is a good signal in terms of dbm? in between work/home mine stays in between -90 to -120

I have had my SGIII for a few weeks now and also notice a lack of 4G strength, and I am in NYC. I am coming from the Droid Charge. I am holding off on doing anything until the JB update, if it comes within a reasonable amount of time...i.e. within the next month or so.

Basically, ALL Saumsung radios suck.
My old Rezound has a MUCH MUCH better radio than either my G3 or my Wife's Droid Charge.
I am talking about actual use, not how many signal bars are showing etc....

hmmm...my issue with the Charge was not so much the 'top-end speed' of the radio, which was really good when in a good area, but rather the 'glitchiness or bugginess' when switching network areas, or with certain applications. For instance, I commute on the train to NYC every day from a dominant 3G area. When the train would switch into the 4G covered area, the radio would not automatically switch over to 4G until I would either do the airplane mode trick (which worked most of the time), or I would outright have to reboot. For the rare times it WOULD switch over automatically, the speed would be terrible until I airplaned or rebooted it as above...I am sure as hell hoping I don't have these issues with the SGIII...

Anyone else having terrible mobile data performance?

I've been with ATT for a tear bow. I had the S4 before this G3. On my S4 I would have LTE most places around my town. Since getting my G3 I rarely get LTE. When I do get LTE it doesn't hold on to that connection very long.
Yesterday I was trying to look something up and I was on Edge (3g) and it was taking forever, so I grabbed my wife's S5 and it was on LTE (also on ATT) and the internet worked great.
Are the radios in this phone just that bad? I'm going to get a new Sim card today to see if that can fix the issue, I'm hesitant to return the phone for another because I'll probably get a refurb and my luck with refurb cell phones hasn't been good

compared to my wife's m8 my g3 gets as good or better signal in my area.

Hmm... I hope its just the Sim card then. They did give me a new one

Radio's suck. Been mentioned a million times, plus LG is infamous for have serious programming software issues.allot of times you have to put it in airplane modethen back on to get it to lock on anything ...kinda garbage, it's too bad cause I love the phone.

I've had my phone for a little over a month now and it's been running great until a few days ago when I noticed the reception was really low in places that I normally get full bars. Not sure what the issues is.

Hmm... This could be a deal breaker if it keeps up
I feel like I'm back on sprint again

So is there anything I can do on my end to fix the issue?

so i got a new sim card, lets see how this goes

I have bad reception at home but can still get 12mb down on LTE. Downtown I get 35 down and 17 up with 4 bars. Signal can't penetrate the brick at home. I drop calls constantly. I'm about to pick up a microcell but data is great.
Much better than Sprint in my area. My Sprint GS5 radio is real garbage. Kills the battery too. The Sprint variant of the GS5 is horrible with Spark.
You may have a lemon radio in your phone.

I'm wondering that, I'd hate to get a refurb and fine out it performs the same

I got a new sim yesterday also. not looking like it's making much of a difference. I can't get full bars unless i'm out on the street. I used to get full bars in my office, relatively close to a window.
Don't really want to trade this if for a refurb to have the same thing.
Is the antenna on the back of the battery case? or is that just a 'booster'?

I've had the AT&T G3 since July 18th with no problems. My old G-note would not pick up LTE in my office at work but I get LTE with this phone. No dropped calls and super fast data. I live in northern VA outside DC so LTE is really good here.

I just realized I'm being throttled... May data has sucked last few days also lol... I'm at crawling speeds

as far as bars go mine seems just about right, but it does lose service a bit more than my S4 did. sometimes my wife and i will both have 3 or 4 bars and she will have LTE and i will be on EDGE or 4G

Absolutely love the device as a smartphone, but unfortunately suffer from the same issues as the rest of you here.
Loses signal where other ATT devices do not, drops LTE for HSPA or EDGE where other devices stay on LTE.
Really hoping the crappy radio can be fixed with a firmware update, and that it isn't a hardware design flaw...

Not sure what if anything changed, possibly something with the network but now I get full bars at my desk, where yesterday I wasn't. I know this isn't very scientific but now I get full bars in the same seat where for the last week I've been down 1 or 2. I didn't think to run a speedtest before but it looks good now, 18.4 down and 10 up.

I'm holding out for an OTA to see if it gets any better before I bite the bbullet and get a refurb

That's weird
I feel like mine holds onto LTE better than with the old sim

I also forgot to mention that when I had my Sim swapped out that ISIS (Did they change the name because now it says ' Soft Card') doesn't work. When I launch the Soft Card (Isis) app it says that i need an enhanced SIM. So it looks like I have to go back to AT&T to get yet another SIM.

Of another G3? I wouldn't waste time doing that. Sounds like they're all the same radio-wise.
Waiting on an OTA too... but if nothing comes, I will jump ship to another device altogether. One with a competent radio.

I want to root and try to change this in the build prop.
Permanent LTE Option
# default value is 9
ro.telephony.default_network=12
Part of me thinks it will help
I believe this makes the phone hang onto an LTE connection as long as possible
