T-Mobile subscribers: How is your GPS before and after modifications? - T-Mobile LG G2x

The G2x is my third Android phone. Prior to this, I had the Optimus M on MetroPCS, then the Optimus V on Virgin Mobile. GPS and navigation worked amazing on the Optimus V and would lock on instantly.
When I first got the G2x,I noticed that GPS was practically unusable. By the time it takes for the phone to acquire a lock, I'd either be lost or already at my destination. Before I had my phone rooted, I'd access the LG secret menu and try to make changes there, but it didn't seem like anything made a big difference.
I've been rooted for a few months now and running various ICS ROMs and GPS is still hit or miss. Sometimes it'll lock at a reasonable time, others it's just wasting my battery and not helping me. Then, even when I am locked, or often will lose the GPS signal and have to search for it again.
Is this a T-Mobile thing or a G2x thing or is it my location? I live near Oakland in the SF bay so I'd think we'd have good service over here.
What is your experience with GPS on this phone and carrier? I honestly want to switch to Sprint once my contract is up (and might even terminate early). Thanks to the development community here, the G2x is finally a decent phone, but I've only been unimpressed by T-Mobile's service since coming from Virgin Mobile.

GPS has nothing to do with T-mobile. It has more to do with the phones hardware and some with it's software. The newest baseband that was just released for the G2x has fixed all my GPS problems I get a lock quickly now and it works great for navigation and it also improved my call sound quality, but there is a lack of custom ROMs for the new baseband currently the best you can do is the rooted stock V21Y.

So basically stuck with nad GPS unless o want to update baseband or get a different phone?

i basically had the exact same experience as you are describing. But, only while I was on the march 2011 baseband. is that the same baseband that you are on? Fortunately once i upgraded to the July 15 2011 baseband i now have instant locks. (and can flash any custom rom with instant locks. primarily stock 2.3.3 roms. Any higher i usually run into slow lock times Ex:Cm7 based roms.

The new March baseband is the only to fly. Here's my lock in under 5 seconds.

You genuinely want to upgrade to the new 21y firmware, I was Oakland CA today and I had no problem using Waze to navigate around the big mess on 880S on way to airport. GPS on my g2x was way better than the iPhone from work, but never would have been able to do that with the older 21e firmware.

[Q ] Rogers or AT&T?

Hi all! I live in Argentina and I want to buy a Captivate either in USA or Canada (can do both). The reason is they are $200 cheaper there. Yes, i know.
Well, the question is which Captivate to get, the i897 or the i896 (Rogers). I believe there are no GPS issues with the Rogers version but I'm not sure if one can use the custom roms from the i897 on it, and if the gps still works fine when the rom is changed.
I'd really like to be able to use the gps.
Please help me decide...
Its going to be hard to find an answer since most people here only have one or the other however i can say this
I bought mine from rogers and had absolutely no problems with the gps
I then installed a gingerclone rom which is 2.2 and there were no problems with the gps
I also upgraded to the 2.2 froyo ATT using odin and still no gps issues :S.
So basically... If your going to upgrade it to a rom you like, it should be fine
Get the rogers one if you don't want the ATT branding on the front of the phone. The rogers captivate only has the samsung logo on it.
Also the rogers captivate stock allows for side loading and mobile ap.

My biggest gripe right now is problems with unlocking the phone. I've read the forum but found that a lot of people report mixed experiences with this.
I believe they share the exact same radio bands, so you're free to choose. Anecdotally, it seems people are happier with the Rogers one... and many of them were probably built later (newer) than the AT&T ones which may help avoid some of the gremlins that early adopters have reported.
Yeah, but unlocking seems to be very hard and not at all a certainty...

Official Australian Optus GB rom available...kind of...

As some of you may know, my O3D was sent to LG service repairers Evertec to fix a broken power button. I asked them to fix just the power button under warranty - my phone was on froyo (i was on the leaked GB but because of ghost calls and data dropouts i reverted to froyo) and i just got my phone back today with a note saying the power button was fixed and they flashed my phone to "the latest firmware"
Lo and behold I booted to a fresh install of an official Optus GB rom - baseband 20b but perfect reception. no dropouts or ghost calls. i think it may be rom related.... i do have some bloatware but at least i have no reception/data issues
im not sure if this rom is available ota or for download but the service guys seem happy to flash it on repaired phones!
yes,20b is online,but still not rootable
I had 20b installed before but it wasnt the Australian Optus rom... Whatever rom that was, it always gave me grief....now no problems at all. in fact optus even sent me a message with settings in it - i havent activated it as yet as my reception is currently working perfectly fine without it.
Guys, please be aware that LG version numbers ARE NOT CONSISTENT, at least not the way we think of it. European v20b is not the same as India v20b.
In fact, each region has it´s own version branch, so you can perfectly have, for example, Romenia v21a with the same baseband of Croatia v20b.
So, don´t be fooled by equal version numbers: you can only compare version numbers when comparing software for the same region. If you cross regions when comparing, you will get it all wrong.

I installed the same rom as you, 20B Optus, took my external SD out and formatted the phone to factory, for one day the phone worked well then the problems started as before 3G getting stuck can't go to airplane mode I had to restart the phone, after it happened over 4 times I installed froyo. Same thing exactly happened to my friends O3D, Evertec changed the board on my phone when I took the phone for service for the random rebooting problem, now it is very hard to sell the phone if I tell the potential buyers the phone was serviced. So I am stuck with it.
I use it like Thiaz as a media device now and I use My Iphone 4 as my main phone.
what is the use of a phone if it can't be used as a phone?

I noticed you're posting from a 925... Mines a 920.... I never had a random reboot and I've installed the Acura and Thiaz roms - used stock roms, OC'd and the only GB rom working properly is this one....
I'll keep my fingers crossed that it stays this way....
Admittedly I never had any issues on Froyo - If this rom does play up I'll downgrade asap. I won't miss the GB features all that much

You noted correctly, but my one is an Optus 920, I was so desperate so I am using Froyo Baseband and the CM GB for the 925, this was my last resort, the phone works very quick with no lag, and I charge once a day, hdmi does not work, and I can't view photos in 3D, but this phone is good for playing games, that is all I use it for.
I have intalled the update to my optus lg optimus 3d thought lg update tool, i have had 2 missed calls i did not receve that i know of and really bad battery life. i might have to do a factory reset if this does not fix i will not be happy.......back to lg

Good Luck mate, they will tell you that you are the only one in the world that is having this problem, all the staff at the LG service center (evertech) are using GB without any issues what so ever.
you will be told (you are special)
Ok... Here's the weird thing - I know people seem to be having problems using this rom... I am not one of them (so far) I had issues on every other GB rom but this one. Maybe it's related to signal strength, carrier specific settings or something else. I really can't explain my lack of issues. I do set my phone to 3G only - as I don't want it jumping from 2G to 3G but that's it as far as any phone changes.
*I am using the Optus GB rom on Virgin Australia (they piggyback on Optus - slightly different settings but same network).

Please keep us posted, I am on Vodafone and the signal is shocking where I live (inner west) Vodafone will be updating the network next month.
but I do not have any issues with my iphone at all, and when I go to my other house (castle hill) where the signal is perfect -50 db I still get the baseband crashing.
I used the phone for 2 weeks back in November when they released the Europe Open before I stated getting complaints that I am not answering Phone calls and I missed out on couple Jobs worth over a grand!!!
Quick update.... 1 week later and still no issues - strange but true! No missed calls (that I'm aware of and no loss of data... Perfect reception... For virgin mobile customers on Optus GB rom - no issues.
GPS lock perfect - regaining signal after airplane mode perfect, over 400MB in data in a week and no loss of reception, perfect... This is the only rom that works for me on GB without ghost calls, internal reorganizing crap or loss of reception/data
I can't root and have some bloatware but I can live with that...
Will update if things go bad but for now I'm VERY happy!
Thank you so much for getting back to us, I will be trying the 20A Australia again, this time around, I will take the SD card out, will fully format the phone and only install couple important apps that I need, I am doubtful but at this stage I am willing to try anything. will try the 20A for 3 days and will report back.
Edit:
Day one: No Freezing and no missed calls at all.

4G Data Drops

I finally got someone at Verizon to admit that the 4G dropping issue is at the top of the known issue list. Each time I have gone in the store I have been met with 'surprise' that this is an issue. Invariably they have tried to replace my SIM card or phone none of which has worked. The notes on this issue that the phone support person had were rather disturbing.
The first one indicated that this was a known, accepted issue and that the phone was working as intended. Ack!
The second note said that the vendor was working on the issue...IE HTC.
So...onto HTC I go...
The HTC rep also admitted knowing about the problem. He said they were working on a software update to correct this. This of course led to discussion about ICS. According to the HTC rep I spoke with the update has NOT officially been cancelled at this point. He could not say whether or not the fix for the 4G drops they were working involved ICS, but did seem to indicate it might. As usual no remote ETA as to the fix.
Truthfully I could care less about ICS...I would just to have dependable 4G that didn't drop every time I try to use GPS to get home from work, stream music for my kids, or check Facebook.

I just got a new sim and so far so good. What rom and radio are you on? Radio's tend to be a big factor in data dropping.
Sent from my ADR6400L using Tapatalk 2
Yeah if I run twisted build my 4g will drop but if I use let's say skyraider I have no data drops where ever I go. Many times you need to find the right radio for the rom you use.

Well...I have tried the .19, the .9 and the leaked ICS radios when I tried the ICS builds. I actually don't know about the leaked radios as I had too many other issues with ICS at this point for me to use regularly...but the .9 and the .19 both give me pretty regular 4G drops. I just dropped back to the .3 radio this morning to see if that helps.
Thanks for chiming in. Maybe I should try another SIM card...only replaced that once...have replaced the phone 3 times now. I spoke with Verizon AGAIN yesterday and was basically told what did I expect with a two year old phone. I guess they expect you to have to buy a new phone every two years to keep them working. Freaking consumer society.
A level 2 tech told me that the drops are also related to the fact that the 4g network isn't fully implemented. What we get most the time is a 4g extension that was put in place to expand the network faster. They also told me that the parts of the network that are a 4g extension get only half the speed of a fully implemented area. The suggestion I was given was just disable 4g when I'm in areas that have spotty coverage which actually helps. The problem seems to show itself on the hand off between 3g and 4g. Almost like the phone gets confused on which network it should be on.

I think I am in a crappy 4g zone. But now you make me wonder about that...
I'm in an area with solid 4G coverage (I use an LG Revolution). I just installed a ROM on my brother's Thunderbolt for the first time last night, largely prompted by his phone being stuck on 1X regardless of where he is. Sadly, it didn't seem to help, even with trying to flash a few radios. His friend also has a Thunderbolt, and his has no connection problems in the same area. Who knows.

[Q] Will Installing a T-Mobile Modem Brick My Phone??

I ditched Verizon and went with T-Mobile pre-paid, only 2G data but its a temporary solution and I get service for 3 phones for $90.00 a month.
I so far have a stock t-mobile rom installed, android 4.1.2 with no porting needed and wireless calling and other such bells and whistles work just fine.
Now my next step is I would like to install a T-Mobile radio to complete the scene. Would this brick my phone? Or perhaps delete my IMEI?
How can I back my IMEI up, or any other sensitive info for that matter?
I know I may be chasing a dream but I am still trying to make HSPA data work on this phone with T-Mobile. Chances are slim but if I pull it off I can be somebody for 15 minutes. . I am in an area where every possible T-Mobile spectrum is floating around in the airwaves since they purchased MetroPCS.
Thanks in advance for any help and/or advice. I am working 16 hour shifts for a couple of days so I will be slow responding.

Flashing any modem except verizon and you stand a 99% chance of bricking your phone.
Rrason being is each provider has the radio hardware built to their specs/ system. Put different firmware in there and you have a brick.

AT&T G2 LTE signal problem?

Hey all,
I recently picked up a LG G2 (second hand)
and I believe I have some issues with the phone not picking up LTE so easily.
Before this, I had Iphone 5, nexus 4, G Pro, Gnote2, etc... and they all picked up LTE just fine at my home
However, G2 rarely picks up LTE signal and it is mostly on HSPA+ (4G Icon) I believe.
I took it into AT&T store to see if I could get a new sim card but when I got there, the phone picked up LTE no problem.........
Looks like many Sprint users are experiencing same issue.. is there a fix for this??
*The phone is currently on stock / non-rooted 4.4.2
Thank you in advance!
I'm in the same boat as you, my data will work for a good 30+ min and then all of sudden no network for 30 seconds or so. I've also been unable to connect to a lte signal I've only been able to use hspa, searching the threads on here have been hit and miss with a lot of vague answers but nothing clear cut if anyone's dealt with this and has a clear fix it would be appreciated.
Sent from my LG-D800 using Tapatalk
A little update to this, yesterday I went to AT&T to see if I could maybe clear this up with a new SIM card and while waiting I checked out the two G2s they had there, these two display phones were literally 10 ft apart and one had lte while the other one was stuck on 4g only. I think this is looking more like a hardware issue now after checking out both store phones on display, I'm going in today to swap out my handset to see if this will solve it.
Sent from my LG-D800 using Tapatalk
Here's another update for those with lte or signal loss issues, after trying everything I could find on these forums the only answer was a warranty swap out, as soon as I put my SIM card into the warranty phone let showed up and after half a day I haven't experienced no random signal loss at all.

Interesting...
This is interesting. Currently running CM11 latest nightly and I thought it was due to CM codebase. It looks like non-CM related?
Please keep the details coming. When I have time, I will flash a stock ROM to see what happens. But at this point, it looks scary that maybe hardware problems might be there.
For comparison, 2 iPhones literally next to G2 had 3 bars with LTE while my G2 had no network.

After a full day and a half use now im fulling supporting the theory of a hardware fault. Before returning my phone for a replacement i was fully rooted on gardys kit kat rom with recovery, i had read that supposedly rooting or flashing was apparently breaking lte so i went back to the stock jellybean rom only to discover the issue still there, i then fully updated to the over the air kit kat update which also did not solve the issue. It really does look like theres a issue with the phone itself.

Oh wow. Thanks for your reply.
So i have tried working on this and so far no good.
LTE picks up good when i walk into an att store and that is causing difficulty with store workers..
I get stable, steady connection with hspa+ but rarely pick up LTE..
What is the process of getting a replacement? Its way over 15,30 day period for me..
Sent from my LG-D800 using Tapatalk
For me lte did not work at all even in store, I can see where you might have a issue if they can't reproduce the issue but just be persistent and they should take care of it for you. As for warranty you have a year from your purchase date for a warranty claim through At&t, I went through a device support center which you might have depending on where you live otherwise you can send it in. You must revert back to a complete stock state or you will be more than likely denied.

Got it fixed after several attempts with new sim cards! Picks up Lte fine! Wootwoot
My fix
call att tech support make sure that the lg g2 imei matches your line/sim card
So I went through a bunch of phones in the past couple weeks, I have at&t service but my last phone was verizon droid maxx. Next I went to the AT&T store and he put my phone number under the new sim card for my AT&T LG G2 but the rep didn't ask me for the IMEI or look at the phone at all, he just got my line on the new sim and I left. I noticed the phone was going back and fourth to LTE but it was 4g (non LTE) about 70% of the time. I changed APN settings, I updated, nothing worked. Then I remembered a long time ago that if you go from android, blackberry, or iphone to another type of phone you would have to call att and make sure something was changed so I called att tech support and asked if they would put my IMEI under the new sim, the tech said yeah I should do that because currently my line doesn't show I have the g2 (make sure to call tech support because online it'll show you have a g2 and if you call costumer service usually they will see the g2 too) and after that i reset my phone and got LTE 100% of the time since then.
