T-Mo G3 Problems? (Trying to get some D851 Specific Discussion)

So... over on the main G3 section, there's a lot of talk about several issues.
1) Phone randomly shutting down, or failing to come out of deep sleep (after overnight charging, for instance - but also at more random times). Often, folks are having to pop the batter to get it to come back to life.
2) Problems with using the headphone jack as an aux-output (for car or home stereo, as an example). There are glitches with the phone not realizing it's plugged into something, and glitches with the phone sending out dirty signals in between tracks (pops, crackles, etc), and with a buzz or hum in one side or another.
3) Problems with the phone becoming exceptionally warm. All phones get warm, but some users are reporting that their phones become extremely uncomfortable to hold, and simultaneously begin to have hardware problems (phone just dying completely, or screen flicker).
4) Those who have purchased multiple phones have reported issues with screen variances (some screens will appear warmer or cooler, more blue or more yellow), even with phones that were purchased from the same store on the same day. Some have reported needing to get a replacement phone and noticing this.
I'm curious about getting some discussion going here. Have any of you here had these problems with your D851 (T-mobile) G3's? have you had any major problems with your devices, or needed to get a replacement? Why? It seems like many of the problems are with the D855s, but I'm curious how many are truly affecting our D851s.
Thanks for the feedback!
TL/DR: What big problems have you had on T-Mo G3? Needed a replacement? Thnx!

My first G3 I bought on launch day from the t mobile store had overheating and rapid battery killing issues even after resets and doing everything from scratch. I swapped that one out yesterday and the second one I got was running good but then I ran into the headphone jax bug where it doesn't recognize the headphones being plugged in and after about 4 or 5 resets and wipes it finally starting working.... Right now I am debating if I should just get another G3 or what because the next one might have something else wrong lol.. I go to t mobile today so hopefully everything will go well.

Only one of those I've experienced is the problems with the aux jack

My G3 is perfect to the point I even recommend it to my girlfriend who ended up paying cash for one... Well with hers it wouldn't wake up from a deep sleep while charging and needed a battery pull. I'm definitely going to keep eye on that.

Haven't had any of the issues with mine. Although I just got it yesterday. It worked fine with headphones but haven't tried plugging into my truck yet.
Aux worked fine in my truck..

The only issue I have is the aux in my car. I turn on Bluetooth so I can still play music in my car. I'm ok but lg should definitely fix this.

Hopefully won't get scolded because I already mentioned it in another thread... :/
- My first G3, an AT&T had an issue where knock on didnt work most of the time. Returned it and went to T-Mobile.
- My current T-Mobile version has display issues. Screen has an overall yellowish tint and has been getting worse by the day. The top right corner of my screen just started getting more discolored as well. My brightness is abnormal... it looks as if it goes to 150%, lol. Too bright even on 0%.
Went back to the store, after comparing my phone to the demo models and the salesmen's personal phones, mine was determined as defective. Was going to exchange and they went back to get one phone after another - all 3 that they opened had worse screens than mine. They think they may have gotten a bad batch and advised me to come back in a week when they hopefully get a shipment from a different batch. I dont feel like waiting a week and gambling again, so im going to return it for a full refund. Going to get an AT&T version and unlock it for T-Mobile.

Quick update to what I posted earlier... I went back to t-mobile to replace my 2nd G3 due to Aux port not working and they gave me a new one and I have to say that this is the best one i got screen wise. OMG its beautiful.... colors are balanced, temp of the screen is near perfect not to cold not to warm, sharpness yes its still crazy high but it doesn't have the blurry looking effect with text and certain apps and everything else seems to be working like it should be. Hopefully the 3rd device is going to be the charm if not then idk lol...

Did you buy your device outright? I'm just switching to Tmobile, ordered my G3 online. And for now, I used their equipment payment plan. I'm gonna wait and see how bad the network is in my area. If I go for it, I'll be paying it off straight away. Just curious how Tmobile is about replacing devices that are defective. Are they pretty on top of it?
Or should I invest in some kind insurance? (actual insurance... uggghhh... or the Jump program (also doesn't appeal, but as flaky as these things have been, I'm worried))

Yea I bought the device outright because I sold my S5 and I don't use jump since I switch phones a lot. As for insurance and defective devices I use Tmobile's just without jump and they are pretty good with swapping bad devices. My M8 had a network/sim issues they literally sent 5 M8's because the issue wasn't going away but they made sure the problem was fix lol. Even my S5 screen went bad and they had me a replacement device the next day... so I can't really say anything negative about there warranty/insurance polices. Even with the G3 they replaced the device as soon as i showed something was wrong with a brand new one in box

My opinion

Well.... Ive had my g3 since wednesday and yes the headphone jack works but this thing refuses to enter deepsledp for some reason...and im noticing some almost grayish lines behind text when I'm reading a webpage or text

@Eldartho well i would say get it replaced. I did notice the lines with one of the display units in the store. LG is very hit or miss with the displays on the G3.... My current replacment is saturated like my s5 out the box but my last one was dull like z2/z1 so the displays are going to be a raffle on getting the right one. As for the deepsleep that sounded like the problem my first device had and it would always stay hot and drain extremely fast

I guess I'm either the luckiest guy in the world when it comes to getting phones, or just not anal retentive enough. I've never had to return a phone due to the issues that people post on XDA. I guess I'm just really lucky.

You are lucky, lol. Last 3 phones I bought from T-Mobile (M8, S5, G3) have all had to be exchanged due to hardware issues. Beginning to think they build the T-Mobile phones with bottom of the box parts, haha. To be fair though, I first bought the AT&T G3 and returned because Knock On wasn't working.

I bought mine off of swappa from a beta winner and it is perfect. Same with my s5. I am lucky x2 it seems

Is anyone else having issues with pressing the settings icon in the notification pull down?
I keep trying to press the top right gear but nothing seems to be happening.
Is there some setting I'm missing or it just not suppose to work that way?
Thanks

Has anybody else had "Cell Standby" high on the list of battery drain?

I have issues with the keyboard reverting back to the stock keyboard even though I was using Swype. I had to freeze the stock one to stop this. I also have some apps logging out occasionally.

Had the headphone jack issue ... Went to the store to exchange n it worked all of a sudden ....bought bluetooth headphone just in case lol got the LG tone pros

LG G4 Questions

I'm planning to upgrade to the LG G4 from the G2, because I have enjoyed the G2 mostly, other than the fact that it went into boot loops and the wifi stopped working.. but I have a few questions.
1) If the speakers are on the back, can you hear properly when you're holding something, doesn't your hand cover it? And even if you're holding it horizontally to watch a video or something, is the sound quailty bad?
2) I heard that LG officially announced that they released phones that have boot loop problems. So after a year when my warranty runs out, and the boot loop starts, will they still fix it?
3) How is the quality of the Android 6.0? I live in Canada using TELUS.
4) Also when the LG G5 comes out in a week, will the price drop?
I would really appreciate if someone would answer these questions. Thanks!

Hi- Almost a week ago, even I upgraded my phone from G2 to G4. So far the experience is really awesome. Please find my answers below. Note: I am not a phone expert and I am putting across my views as a normal person would be able to explain.
1) The shape of the LG G4 is in such a way that the back speaker will not lie flat on its face at any time. So whenever the phone rings it will loud enough. Also when playing games I don't think the speaker will be covered with anyone hand. Again the positioning of the G4 comes into picture. I have installed couple of games and I have not found any issues.
2) Yes. that is correct. LG also accepted the fact about the boot load issues. This issues were primarily found on phones that were released before May or June and the motherboard was replaced free of cost by the Service Center. The one that I bought has the manufactured date as of December 2015 and so far not even once I faced any boot load issue. Probably you can check the manufactured date.
3) I have no clue about Android 6 as I live in India and I am still waiting for the update.
4) Regarding the price factor, I doubt you'll see a drastic cut in the price once the G5 is released.
I need not tell the good things about the phone cause you might have already learnt about it. But yes, it now supports quick charge. :laugh:

Thanks!
Now can someone who has used android 6.0?? per chance??

I have had the phone for 3 weeks soon, and it has two serious problems: keyboard is laggy, meaning that when you write fast, it won't recognize all the presses. There supposedly is an update for the LG keyboard regarding that issue, however I don't have any updates available for the keyboard so I think I already have it, but it is still very laggy. Which leads to a conclusion that the issue is either throttling down the CPU or then it's a digitizer issue not being sensitive enough. Note that unlike Samsung phones, LG doesn't have an option to change the sensitivity of the screen. But as I write now, the lag issue appears when typing and it freezes the keyboard for about 0,5 secs and also the screen too, so it would indicate either a software bug or CPU being throttles or who knows what. Either way, I hate that one of the most recent LG flagships have a problem of this kind... Regarding warranty, I contacted LG Finland and they just replied that most likely it has no problem, even though I've never had any issues like these on my earlier Samsung phones...
Also, Knock code doesn't always wake up the device, neither does double tapping the screen, which most likely goes back to either CPU, software or digitizer issues. Hate it when I should be able to wake my phone when I'm having the phone in my car holder and it won't wake up because of these issues with the device. I do have the 6.0 update available but haven't had the time to install it yet, also i've heard that as it handles something differently compared to Lollipop, some apps might not work and so on... Which is turning my willingness to update down a bit.
The phone has potential, and it's a shame that because of these issues, I might go back to Samsung soon.

Thanks for you opinion!

i disagree with heartagramm.
when I bought the phone (2 weeks ago) it came with the 10a firmware (the first one, i think) and it was super smooth, no lag issues, everything it's awesome!
The bootloop issue its present on the 505 devices, (the first releases, manufactered in may)

Stay on G4 or move to OnePlus 3?

Guys, how do you think?
I have my G4 (S/N 512), camera is perfect, CPU is good, screen is excellent.
I don't care about updates, but I love Cyanogenmod, clean Android etc. I want to mod my phone, personalize it in every way I can. Unfortunelly I can't with locked bootloader. I could just unlock it, but I'm aware of bootloop. When it'll happen my phone will be just paper clip. So I'm thinking. The OP3 is near. OnePlus got great terms of guarantee. But still, I'm kinda in love with G4. I jumped from SGS3 to it. So it was my designed phone.
Anyway, what do you think? Will my phone brick? Move to OP3?

Stay until you get the bootloop (as you expect). It is kinda risk now to jump over to OP3. I know the rumoured specs are good but you wont loose by waiting a bit for some few reviews

lol op?Support epic joke.

Which serial number is your phone? I have a 510 device and i believe those are safe from the bootloop issue because those have the v1.1 motherboard. I unlocked the bootloader on mine because of this and it has been quite nice with CyanogenMod 13. However, like yourself i'm debating whether to upgrade the phone later this year. I don't 'hate' the G4, in fact it's a nice phone with a fantastic camera, screen and good performance. But there's something about it that i don't like, i bet this sounds stupid but it's just such a boring phone, honestly. Before this i had the OnePlus One and that felt like something genuinely special, and i kinda wish i'd stuck with that instead of buying the G4.
I doubt i'll go back to another OnePlus device because of their shocking customer service, if you end up with a bad device then it seems like you're gonna be ****ed for a few months. There was one person on Reddit who sent his phone back in February and still hasn't received it as of yesterday, like what the hell is that about. I'm going to wait and see what the new Nexus devices are like in about three months, i think that's the way forward for me because it would be nice to have a device which receives updates quicker than anything else, and always stays on top with the vast developmental community behind it. Only problem with those is the price and lack of a memory card slot, but we'll have to see what happens, maybe the prices will be a little more affordable this time to compete with the OP3 and similar devices.

What about Moto Z Force, if it's not only for US market? Depends on the price of course.

I just upgraded from my G3 to a factory refurb G4 and so far I really like it all except for the issue where you cannot wake up the phone by double tapping the screen like 99% of the time. There's supposed to be a way to upgrade the lg keyboard app unless you are, like myself, on Verizon in which case they so graciously removed all the useful settings menu items such as app upgrades, etc...

i have 601 how do i know what MB version i have?

If you want to hear my opinion for new phones:
Wait 1/2 to 1 year. Why?
• You know, if the phone will get its love by devs.
• It's also much cheaper.
• Many little hardware-bugs will probably be fixed.
3 good reasons to wait. New != better. Sad new world, I know. Except it's a Nexus: Same price until new one is released, same hardware - but devs will love it .

There should be a sticker on the inside of the box which states the serial number and has the motherboard version at the end in closed brackets. But as your phone is 601, it will have the updated motherboard and so you're safe from the bootloop problems.

thanks ill check it out.. but theres still people reporting bootloops even with 603. ??
i have it bootloader locked just in case. i own tmobile h811..

I think I am *very* close to going with the OnePlus 3. Just need a little more review/confirmation to make the jump.

Considering OP3 already has a CM13 build going and kernel sources out, I'd honestly get rid of the G4 while its still worth something. I would've done the same thing if it weren't for the fact my piece of garbage G4 decided to bootloop literally days before the OP3 release.

My double tap to wake used to work great. Then I got bootloop issue, had phone repaired from LG, and double tap to wake basically NEVER works. Not sure if it'd be worth a FDR or what.

Mine bootlooped friday and I'm going to get the OP3 in the next few days. I'm trying to get my G4 repaired, if LG dont do it then I'll use my insurance to have it replaced. I plan on using the time I have without it to see how I lkthe OP3. If I like it, I'll sell the G4, if not, I'll sell the OP3.
I've read a lot of bad things about OP3's support, but in trying to get my G4 repaired, it can't be much worse than LG's (edit: since I made this comment, I've been on LG Chat on their website with a really helpful guy called Carl who's said my phone is covered with a 2 year warranty and they will fix it - much better than the cookie cutter email response team).

No removable battery on the OP3. They claim to charge their phone to 100% in 45 minutes. The G4 can be at 100% in about 3 minutes from shutoff to reboot with a fresh battery installed. I love my G4.

I loved my G4 till it stopped working and LG refuse to fix it because rooting voids the warranty.

This statement is false and very dangerous for users. All smartphones, even with S/N starting with 60x are prone to bootloop problem. I have my LG G4 with v1.1 motherboard, S/N 602 and guess what happened to it...

Well, that's news to me. When i bought my G4 in December the bootloop problem had already become widely known, and i did extensive research into it on XDA and other websites, but at the time all 510 and 511 devices were deemed to be completely safe. If those devices were affected by the bootloop problem then i wouldn't have even considered buying it.

LOL, there are even cases of the new G5 bootlooping. LG has become such a joke. And it's a shame because the G4 would've been a perfect phone if they had caught the bootlooping and image retention issues while testing it.

Screen ghosting LG G4

Hey guys,
Yesterday I noticed some screen ghosting on my LG g4 on the top right where the battery icon, signal status etc are. I turned it off for 6 hours and noticed it got slightly better then i used an app which stimulates all the pixels on the screen for about 8 hours by flashing different colours. After this all ghosting went away but after i used my phone for about 2 minutes it made a new ghost. Please help me fix this permanently. I am currently using the same app with the intention of keeping it on for a full day.

It can't be fixed. However you could replace screen.

Honestly LG has given me the worst android experience to date. Had the damn phone for 3 months an it was the taiwanese g4 which has no way to unlock its bootloader. The worst part is that the screen ghosting came up on the same day i decided to sell it and buy a oneplus 3 instead. Now i wont be able to sell it for a good price and that means i can't afford the oneplus. Never buying from LG again.

I understand exactly what you mean.

i have it also and it's ANNOYING as hell!!! I returned mine 2 weeks ago not only because of this but also because i cannot see nor connect to a 5 GHz Wi-Fi network.
Just 2 months prior top this the phone killed itself (not even 1 year old) and had to get a new PCB. LG if you are reading this, i want my money back.
Note to the people, please don't buy LG crap!

LG G4 bootloop
The bootloop - problem on all the LG phones from the main series is caused due to a less safety check in fabric and causes cause the processor releases from the mainboard during heat, mechanical load etc and the connections were broken! To fix, the processor have to pushed back on the mainboard with heat - I think a hair dryer is a good way to do that
If there are any other problems with the CPU itself - I don't know but sometimes the processor itself can be partially damaged
I've even a G4 which has stoped working on June.04.'17 and I'll try to apply this step in a professional environment. (you've to fully open it, put a hair dryer on the processor, heat the processor and push it down on the mainboard) The best video on yt to do that: search for "LG G4 BOOTLOOP FIX REPAIR VIDEO"
>>By holding the vol+ -key and plug in the USB-cable it bootet once... ..and works... ..but then heats up! - That might work for quick saving data on the PC!<<
I hope that could help!

How to Determine The Wear and Use of a Used LG G3

I need to buy a used LG G3 D851 off eBay. I'm trying to determine if there is a way to find out the wear & usage on the G3. Looking at the physical condition of the phone isn't useful (cases & screen protectors protect against wear & tear). After buying (and returning) two broken G3s I've learned that "refurbished" means "we cleaned it with a towel", and that "new" means "a used phone in the original box".
As I understand it the only thing on any mobile phone that really wears is the camera which degrades over time. I thought that there was a hidden menu option that had an entry on how many photos were taken, which would help, but I can't find it.
I was hoping there would be a hidden menu timer or counter somewhere that can tell me how often the phone has been used?
Any hints or suggestions would be greatly appreciated! :good:

I have had close to a dozen LG G3s over the last 4 years. I have been trying to find a decent D855, but run into D850s , 851s, LS990s and VS985 for parts.
The biggest problem with these is the poor manufacturing of the components on the motherboard. The phones are dirt simple to take apart and swap parts on, and, by now, you should assume that the phone you are about to buy is not what you think it is.
Like George Washington's axe. Someone swapped the handle, then someone swapped the blade...
If you trust the seller to be honest, get a used one that has had little use and ask the seller if it bootloops, has wifi issues, bluescreen, fadeout...these are all motherboard problems.

Thanks @rs899 that's the problem I've had. In one case I bought what was supposed to be a D851 but it was a screen-locked LS999. Another one had WiFi that didn't work. In every case the phones were advertised as refurbished and "passed our extensive in-house diagnostics".
In every situation I had to file a complaint with eBay to get a refund as the seller was not cooperative.

At this point in the phone's life, it is unreasonable to spend much on these. I myself put a couple of phones together out of parts , used them a few days, and sold them as "used" on ebay fairly cheaply. If anyone complains in 30 days I will have them ship it back and refund them (or just simply refund them). The motherboards are a time bomb. The MBs in the ones I sold may not have been used much and may last for some period of time...or not.
I have a D-851 that I thought was pretty reliable. It has started to forget my wifi. The end may be near for that one.

@rs899 thanks for the info. BTW I have long fingers, and the back buttons on the LG G3 are perfect for me (I looked at the G4 but it is famously unreliable even when new & too big for my needs).
My daily driver is a rooted LG G3 running stock KitKat. I'd like to upgrade to a Marshmallow ROM but I'm nervous about losing functionality on the phone if the upgrade goes bad. So my plan is buy another LG G3 D851 and do the upgrade on that, then transfer my nandroid backup & microSD card to the new one. Maybe I'll give it one more shot on eBay & see if it works out. If you have a d851 for sale DM me your eBay ID & I'll check it out!

I don't have anything for sale right now. I have a D-850 I am playing with and figured out how to put Lineage 17.1 on, but now it drops wifi. I have that D851, but I don't trust it either. A very bad D855. Nothing I would either use or sell to my worst enemy...

You wrote that you replace parts on these G3 phones. Do you know if the ear speaker on the front of the phone loses clarity over time? I'm wondering if I should go through the trouble to replace mine. Thanks
