How to boost performance and improve outdoor visibility of the LG G3 without root

How to boost performance and improve outdoor visibility of the LG G3 without root
The LG G3 screen might be the sharpest tool in the mobile display shed, but it does have an annoying feature or two in its turn, too. The high-res Quad HD panel is a battery hog, for instance, preventing the G3 from reaching the same level of endurance in our tests as the rest of the spring flagships. Moreover, it has the habit of dimming itself automatically under the slightest pressure, while the panel is not exceptionally bright to begin with, which soon becomes a torture when you have to use the phone outdoors on a sunny day. LG lists its 5.5" Quad HD panel as capable of 430 nits of peak brightness, which might be an achievement considering the 1440x2560 pixels resolution, yet nothing to write home about compared to, say, the iPhone 5s or Galaxy S5, which can hit much higher maximums when needed, grabbing our improvised outdoor visibility test accolades.

As we mentioned, an additional problem is that LG throttles down the display's brightness automatically pretty often, especially when the phone's workload is fairly high, in order to prevent overheating and battery drain. This reduces the brightness even further, so when the phone is already stressed, hot and bothered, and you have to go outside with it on a sunny day, you are getting even less peak brightness than what you bargained for - a double whammy. 

Well, you can prevent the thermal throttling of the G3 here with a simple tweak that doesn't even require you to root the phone. Be careful, though, and use this at your own risk without pushing the handset too much in that state, as the manufacturer has placed those limits for a reason. It might potentially overheat in some scenarios, like placing it on the dashboard of your car to use as a GPS navigation device at maximum brightness, for instance. Here's what you need to do:

1. Get to the hidden service menu in your LG G3 by keying in the following combination in your dialer, depending on your model number:

3845#*851# (for T-Mobile)
3845#*850# (for AT&T)
5689#*990# (for Sprint)
##228378 + send (for Verizon, limited menu)
3845#*400# (for the Korean model)
3845#*855# (for the international model)

2. Scroll down the list of options, looking for this one - "High temperature property OFF". Put it an enabled ON state, turn the phone off, wait for about ten seconds, then turn it back on until the lock screen appears.

3. Enter again the respective dialer sequence for your model, find the "Thermal mitigation daemon OFF" option in the list, and enable it to ON position. Now turn the G3 off, wait about half a minute, then power it back on again. When the lock screen appears, unlock the display, and wait about a minute for the phone to finish syncing and refreshing in the new unthrottled realities.

4. That's it, you can now set the brightness slider at 90% or 100% when you need to use the G3 in the sun, and you will get close to the maximum screen brightness at all times. 

Beware that the automatic screen brightness is a no-go now, so the phone will stay in the position you placed it, without adjusting for the environmental luminance. Also, as we mentioned, don't overuse the maximum brightness setting, especially in tasking scenarios, as the phone might get the hiccups. As an added bonus, however, disabling the set thermal throttling thresholds will result in a noticeable performance boost, which should get rid of any lag experienced throughout the interface, apps or games, and will allow you to brag with higher benchmarking scores, too, if used with caution.

Yep that it is my friend. .I tried out the G3 and took it back a few days later as the phone wasn't all that speedy and the screen was not very bright. I got my GS5 and couldn't be happier it's a much snappier phone and the screen is outstanding. Nothing beats superamoled!!

Samsung needs to go back and research the S2 and S3 and figure out what got them popular. I like their phones but they are way of track compared to what they used to be in my eyes.

overall this phone is very good.If it would had a FHD display then it would beat the sh** out of the S5

Uhh, this phone has a higher than FHD display. qHD is different from QHD. The Galaxy S5 has a display resolution of 1080x1920 at 5.1". The LG G3 has a display resolution of 1440x2560 at 5.5". FHD is over double the resolution of 720p, whereas QHD is four times the resolution of 720p.

He means if the G3 ONLY had a 1080 screen, instead of 1440, it would enjoy performance levels that "would beat the sh** out of the S5".

So why doesn't LG just DO that then?
I dont give a damn about 1440x2560 pixels at 5.5" in a device that spends most of its time with its screen off in a puch or backpack. Í don't need such a ridiculous resolution to see who's calling me. FHD is more than enough for a bloody phone. Not even movies are in 1440x2560 resolution so wtf. This is complete overkill.

LG made this screen only so THEY can brag about it. It's complete BS for common users. They made a grave mistake with this screen it WILL haunt them back.

Lol I still do not get any overheating or automatic screen brightness reduction. Nor do I think the phone has a "relatively dim panel". I cannot even look at the phone at 100% brightness unless I am outside and it is very sunny, because it IS so bright. Half of the time I double check to make sure the phone didnt get BRIGHTER not dimmer without my say so because it is so bright.

I just do not understand how phonearena reports all of this stuff. Overheating? I have never seen it. Lagginess? Never had it. Screen brightness problems? Never experienced it at all.

I am a fairly heavy user as well and I just have not had any of the issues that Phonearena reports.

I also haven't had any complaints about the screen whatsoever. It may not be as bright as some other phones, but at 100%, it is still brighter than I need it to be. So a moot point for me.

I have seen the occasional hiccups when scrolling around the UI. It hasn't been more than a minor annoyance to me, and when it is running an app, there has been no lag at all.

Me either. I've left it in the car all day in the blazing heat, grab it out and start using it at max brightness for over an after after and I've never seen a heat warning. I would do this with my note 3 and it would give me a warning about not being able to charge if i plugged it in after sitting in the car. The LG charges fine.

I have no performance issues.

I checked out the LG G3 in Best Buy. The screen was more than bright enough for me. Any brighter and I would not be able to look at the screen. So I did not see the dimness that some people complain about.
Additionally, I did not encounter any lag when I played with phone.

The problem I have with Samsung is twofold:
1) Quality control issues. After three months of usage, my brand new Galaxy S3 died. Thus,
Samsung had to replace the motherboard in my S3. That was brand new phone!
It was a known problem at that time referred to as "Sudden death."
I no longer had any problems after the motherboard was replaced. However, the ordeal
was still a hassle nonetheless.
2) To date, in my opinion, Samsung no longer innovates when it comes to their hardware
design. Rather, they seem to just watch what others do, then copy any hits out there.
For example, instead of making the Galaxy S5
initially with a QHD screen, they waited for someone else to do it in order to see if the
technology would be welcomed. LG hit a home run with the QHD screen on the LG G3.
Thus, Samsung immediately rushed out another version of the Galaxy S5 that has QHD
a screen(the latter is currently only available in Korea). Similarly, Apple
implemented a finger print scanner first. Shortly after that, Samsung implemented
software based finger print scanner in some of its devices.
Look at the hardware design of the S3, S4 and S5. The phones virtually look the same
physically(i.e. just incremental changes). It's like Samsung is afraid and do something
new and radical like the leap LG did with the LG G3(i.e. a 5.5" screen virtually in a 5"
form factor, and ultra thin bezels ).
We will see if Samsung brings something new to the table when they release
the Samsung Galaxy Note 4 later this year.

I am not saying Samsung does not make decent mobile devices. Personally, I like Touchwiz. Rather, Samsung is not doing anything new and radical these days when it
comes to hardware design.
Kudos to LG for taking some risk.

O,k. I own the G3. If you put it on auto bright, it is very visible outdoors. I have never seen the phone brightness throttled with heavy use, so I am not sure why all of the fuss.

"Problems with Samsung"

1) This can happen to any device with any customer.

2) Nobody innovates. Everyone uses the same SoC, same hardware, same screen, it does not matter who does it first, no phone manufacturer is stupid enough to "innovate" the QHD screen if they know people don't like it. ALSO, the Vivo Xplay was the first device to have a QHD Display.

3) The G2 is almost the same design as the G3, just with a faux metal backing.

4) LG is taking no risk whatsoever using QHD.

Furthermore, LG made an atrocity of a phone because they didn't upgrade the battery or SoC chip along with QHD. That's why the G3 is laggier, and technically should be laggier because it needs to push the QHD display. The battery life is garbage because of the QHD.

You really seem like you're unknowing of the term "gimmicks", that's how you sell phones. QHD is almost a gimmick, and it's completely unnecessary.

"the same SoC, same hardware, same screen" all made by Samsung! Only Samsung innovates at all technological levels. Even Apple depends ion them for vital components.

Hello Mikenike,

1) Well, I have had multiple smartphones from various OEMs. The only OEM I encountered the sudden death issue with, was Samsung. So Samsung
phones simply don't cut it for me anymore(i.e. and that's really because of my personal experience)

2) I disagree with your assessment. Rather, every OEM brings something unique to the table(i.e. whether it is a nice spin on an existing technology or something new entirely). Apple is known for having thin, lightweight devices. Additionally, all the OEMs keep an eye on what Apple does. HTC brought us boom sound. Sony can be credited for possibly making water resistant phones more prevalent. Samsung got us on board with bigger screen phones(e.g. the Galaxy Note series) and gave us Touchwiz(i.e. a decent Android skin). LG gave us Knock code, knock on, no side buttons and a 5.5" screen virtually in 5" a body with the LG G3. Furthermore, ultra thin bezels is now the rave due to the LG G3. Also, even though LG didn't invent the QHD technology, because they were one of the first renown OEMs to bring the technology to market, other OEMs will do likewise.

3) It is unlikely anyone would mistake the LG G3 for the LG G2. The same cannot be said for the Samsung Galaxy S3 and Samsung Galaxy S4. Likewise, for the Galaxy S4 and the Galaxy S5.

4) Every LG G3 review out there to date highlights the QHD screen on the LG G3. It really doesn't matter whether people feel the QHD it a gimmick or not. The fact remains it is a sharper screen technology. Big players like Samsung, Google, Netflix, Sony, Intel and others(even the Gaming industry) are all getting behind higher resolution content.
Their goal is to make higher video content mainstream in the future.
Needless to say, a 2K screen will be able to take advantage of some that higher resolution content when it becomes available.

In the end, there is no one smartphone that is perfect for everyone. People's opinion vary too much for the latter to be possible. For example, I feel the LG G3 is aesthetically pleasing. You feel the LG G3 is atrocious. That's okay.
Personally, I wish Samsung and all other OEMs continued success. Merely, because the more they battle with each, the better mobile devices will be. Then we can each pick which smartphone gets the job done for us.

Their only reason to do this is because such high resolution media is much harder to hack/copy. So people have to BUY QHD content. There is a pure commercial reason behind this. Companies pushed Blu-Ray because they knew that nobody would copy a 25GB movie (that was their intention anyway). Or do you realy think they wan't you to have the best image quality in video and game?

Funny, is that why I see all these moronic re-runs o/t Simpsons, Fresh prince and even old farts like Dallas on today's digital HD TV? The only stuff that is really HD is the bloody commercials.

I too have the LG G3 and other than the occasional stutter navigating around the phone is near perfect. The screen is bright enough and I have no problems viewing outdoors on max brightness and I also haven't seen any over heating issues with the exception on shooting 4k for extended periods of time. This phone is far superior (IMO) to the Samsung Galaxy S5 which stutters and lags almost all the time when I had it. Not to take anything away from samsung because the s5 is a very nice phone but just not for me this time. Their skin is just to heavy and is a real burden on system resources. Could you imagine how laggy the s5 would be with that heavy skin on top of a QHD screen? That's why I think Samsung decided to wait on QHD in the states until they had their touch wiz interface optimized a little better.

Ok. I've had the galaxy s5. Returned it a day later. Laggy . Not impressed with screen. Went to the HTC one m8.. Nice screen but wasn't impressed enough with battery life. Returned it. Waited for the g3. Couldn't be happier. Screen is great. Battery life is tremendous. And it's fast enough. My history of daily drivers over the years.. is HTC inspire. Galaxy S3. Lg optimus g pro {my favorite} lg g2. I usually run different flavors of cyanogenmod on my devices. With the lg g3 I have no intention of doing that. I've rooted and removed any bloatware, changed some other settings and this thing rocks.

Hello epdm2be,

Yes, I do believe the industry wants move beyond 1080p primarily because they
have the means to provide higher resolution content. I also don't doubt that DRM and larger file sizes is part of their decision to go with 2k/4k content. Needless to day, the film industry has the right to protect themselves against piracy. I do not pirate movies because it is wrong to do so. So, regardless of what medium the film industry chooses to deliver their content, I will continue purchase the movies I want.

"So, regardless of what medium the film industry chooses to deliver their content, I will continue purchase the movies I want."

Which is besides my point.

My point is that I'm convinced that many technological advancements aren't (solely) made for our welfare. But that companies and corporations have ulterior motives and hidden agenda's.

No lag and no overheating issues with my G3. Screen is always at 75% and I can see it whether sunny or cloudy or otherwise. Please, don't mess with the thermal settings on your phone. They are there for a reason.

I was as an avid Samsung user. Easy to root, install ROMs or kernels and lists of of customizations. However, eventually one out grows the same routine of installing ROMs and wants a phone that has has better battery life, a bigger screen, and more customization than Samsung has either stock or rooted.

LG G3 has outperformed the S5 and IPhone. Which an old flip Nokia could out perform and IPhone.
