LG acknowledges G4 bootloop fault and promises free repairs

LG acknowledges G4 bootloop fault and promises free repairs
In the fast-moving world of consumer tech, LG's G4 is already veering towards relic status. Last year's flagship is reaching the end of the unforgiving one-year shelf life that smartphones are so often furnished with; soon to be superseded by what's likely to be called the G5. An overall impressive device, the G4 has managed to avoid many of the issues that plagued flagships running on Qualcomm's Snapdragon 810. But while LG's decision to run with the Snapdragon 808 has largely kept it out of the firing line, some owners of the handset have been afflicted with a bootloop issue. LG has now acknowledged the problem, and promised repairs to devices affected by the fault. 

The issue appears to be more prevalent than a couple of scattered incidents. With a growing number of social media postings having highlighted the problem, LG seems to have found a root cause. An issue that threatens any and all G4 variants, the bootloop is said to be caused by "loose contact between components." Simply put, it's a hardware issue rather than something that can be fixed by a simple OTA update, although the company promises free repairs to anybody affected. 

If you have a G4 suffering with the bootloop, LG advises you to take it back to where you purchased it from, or, failing that, your local LG Service Center. The Korean company stipulated in its bulletin to Android Authority that users can expect "a repair under full warranty."

One has to wonder whether LG will extend this courtesy to those whose device isn't necessarily showing the symptoms, but may wish for a bit of maintenance to ensure that it doesn't. Regardless of whether the bootloop issue has reared its head, many G4 owners will now feel in possession of a ticking time bomb. Short of recalling every single G4 handset it has sold, which would be both arduous and costly for LG, it seems only right that concerned parties get a free check-up rather than sitting on their hands in wait for the issue to arise. Whether or not this will happen, however, remains to be seen. 

Do you own the G4? Moreover, are you concerned that your device might soon cease to function as it should? Let us know of your take via the comments!

LG G2 - Broken touchscreen LG G3 - Cracked microphone LG G4 - broken mainboard, very bad leather. Should be careful whenever buying a LG G series phone.

Another overblown issue. Sold tons of G4 not a single one came back with issues. PA news quality is going down the drain. Why no such news for Samsung note 5 screen having green or orange line when put at max brightness? one out of 10 box i open when i sell it has this issue. Why no news about strange battery issues on all iphones model or thats from one iphone to another dont have same reception ( both side by side using same network ) Its funny how its only some company thats get hit here.

You forgot the S-pen on Note5 that Samsung refused to acknowledge as a problem and then fixed it silently in latest lots

I see someone is butthurt at the truth. Any issue I had with the iPhone, it was either resolved through a software update or replaced by the Apple Store with no questions asked. LG has had many problems with their G lineup of phones and I love the little "it has never happened to me" denial mentality. Continue shedding those salty tears.

The only issue with the SD810 is the power consumption, which seems to be an issue as well on the SD808. The overheating issues were really blown up by PA and other sites.

The overheating issue was very bad, some oems like sony had to fix the issue themselves.

Yup, Sony and Microsoft seemed to be the only one's able to tame the 810 last year.

Sony was able to do that with the Z5 compact and Z5 premium. The Z5 and Z3+ overheats, a LOT.

Yeah I had the dame problem. The phone fix not wanted to finish the boot process. Nothing helped, factors resets etc were a waste of time. Due to poor experience with the LG costumer service I decided to eens nu G4 to an external repair company. They tried everything. Even replacing the motherboard did not work. So after a few weeks I decided to send my G4 to the regular costumer service. I had opened the phone so I actually did not have warranty anymore. But within a day they made the phone. Though this is nice, it also shows that they were aware of the problem and had seen it multiple times before. Runs very fast again, but if LG has informed users about the problem in an earlier stage (problem started in October last year), I would directly send my phone to the company. We are talking about a high end flagship, when problems like this occurs LG should handle it better. Because I'm not buying a LG smartphone again.

So you had problem and the first thing you do is not try to get it fixed on warranty, and then you blame LG for fixing it when you finally did?

The problem occured in. October. At that moment, I could not find anyone with the the same problem online. I have had a terrible experience with the Dutch LG costumer service. My nexus 5, brand new, had problems with the screen (unresponsive) so I decided to send it to costumer service. One way or another they claimed I had water damage(1 day old phone, not been in contact with water) and had to pay a huge amount of money to get my unfixed phone back. So yeah, I had problems trusting the repair servic. Just like with the N5, I could not find much people with the same problem and so I decided nfirst to try another company. They also proved that there was no water damage, when necessary. Don't get my wrong, LG fixed the phone quickly, and I don't blame them for doing that obviously. But when they made me aware of the problems in October I would have trusted the costumer service

Well, you must have been very unlucky being one of the first, most people didn't get it until recently, however, a bootloop it's pretty obvious that there is something wrong, no matter how bad the service place is they can't deny it. Also the service places are usually hired by LG/store that you bought from and some just straight up sucks.

Not a single return yet for this issue where i work and i sold ton of G4 so this issue may be much more isolated than some tech website try to make it apear. Samsung and Apple device have a much higher ratio of issues.

It's so sad that a one year old phone devolopes problems. I'm glad I got rid of my G4 long ago.

It is not a one year old phone problem, it's a plastic cheesy poorly made and designed phone problem.

It's electronics, lots of stuff can go wrong and pretty much any phone model has some hardware problem or can develop one, this is why we have warranty.

A boot loop is a death sentence, it's not like the camera has a purple fringe, or a button you can work around fails. A boot loop is a F up, a damn big one, it has happened on the G3 and Nexus 5 as well, LG made cheap crappy leggy crash plasticy phones. The V10 is hopefully a sign LG has seen the light, it is pretty good.

i got the same problem to my g4 here in canada i brought it back to bell, eventhough it feels like the sales clerk there is kinda doubtful about my claim that i did not do anything to the phone, and it suddenly starts booting up in a cycle. but then, after 4weeks of waiting i got a brand new lg g4 in complete package. it was nice but then i already got my new priv already enjoying it so i just decided to sell it :) lucky it was sold as fast as what i am expecting even up to now i have no regrets i just miss lg g4 manual setting in camera as well as the front facing camera thats it! haha!

I knew it. This is why I chose not to keep the G4 because I knew it was going to be riddled with problems just like the G3.

Cheap cheesy plastic poorly made and designed phone breaks shocking I used a G3 enough to know better until LG learned to make their phones better. My first phones were Motorola Droid, Droid X, Droid Razr. So I was used to my phones being made well, then I picked up an HTC m8, very happy it was a tank. I borrowed and LG g3 dang what a cheap cheesy plastic phone, the outsides match the insides cuz the software ran about as poorly as the phone was built. The headphone jack was noisy, a symptom of a poorly designed board they put audio pathways too close to sources of interference. I've played with a V10 and it is better, but they need to go further..
