G3 or G4?

I've been struggling to make a decision between the G3 and the G4. The G4 obviously is the newer device with the better specs, but I didn't see any (official) cyanogenmod support yet for it, whereas the G3 has that going for it already. Having some custom roms available is a killer feature for me in a device. I already read that even only the european version (I'm from Germany) of the G4 can be rooted - is that the reason why there are next to no custom ROMs or kernels at all?
Do you recommend the G3 if I'm going for customizability or is the G4 going to get CM support eventually?
Thanks in advance for any help

No idea about CM but I think we all have root now. I am using the Canadian model (H812) and we have root but no unlocked bootloader.
We flash things using FlashFire since we can't install TWRP. No idea about roms, I don't use them.

If you're looking for strictly customization you won't find much for the G4. Maybe you'd be satisfied with what's available as far as themes, Xposed, etc.
You can change things up quite a bit, but it's pretty far from a custom rom or kernels. If you're not in a rush maybe wait it out a bit to see if the G4 scene improves. In my opinion it's the much better device out of the two. If anything when you do buy the prices could be lower.

I would also like to add that flashing roms can get old after a while. On my G2 and previous phones I was constantly flashing and changing things. Seemed like everything was buggy in one way or another. In the end I was happier with a nice phone where everything worked the way it should.
With the G4 I'm pretty happy with the stock software, sure I rooted and changed a few things appearance wise, and removed a lot of bloat ware. I'm stuck with a stock rom and recovery(stupid Verizon model), but that's ok!

@rick09 Why do you think it's better? Other reasons besides performance?
But the G3 should still be a good phone, right? Currently, I've got an HTC One M7, on which the battery lift has gotten quite horrible... Now I don't really know what to get - I've thought about these (In brackets my concerns about them):
Moto X Play (No replaceable battery)
Oppo R7 Plus (Last gen processor, Huge but unreplacable battery)
LG G3 (Nice overall, but the G4 is newer)
LG G4 (No CM support yet)

Ok look, if you're going to buy one of these phones so go with the G4 H815 (not any other model! because of unlockable bootloader) it will get the cm very soon, the development is very fast,
BUT if custom roms are you're thing and you can't live without it so don't but lg at all, go for the oneplus 2 or the new nexus devices the n5x or the n6p

No, I'm totally fine with CM, but will it really be actively developed given that only a small portion of the G4 users can really use it?

Why not just get your m7 battery changed then and stick with it ?
after two years its not going to be as good as new.

The M7 is by no means a bad device but changing the battery is nearly impossible on that thing. Also, because of a hardware failure which affected the whole M7 series, all my low-light photos look like this which renders the camera totally unusable is some situation. The strongest reason for me wanting to get a new device is that my employer will pay it though, so I'm going to get a new phone anyways, it's just that i've only got a certain budget and the G4 would fit the bill, I think

That's what i wanted to know because some people don't care about that. Also you did not mention any other brands so was curious.
The G3 comes in two variants, 2 & 3GB RAM with storage of 16 & 32GB. The 3GB is the better choice. They did away with this in the G4 and its just 3GB and 32GB like the G2 and optimus G earlier for storage.
The G4 has a much better camera than the G3 which is the same one used in the G2 and flex models. The G3 is a capable auto shooter but the manual controls on the G4 mean more control and better low light ability. The aperture is 80% brighter.
The screen on the G4 is also better and brighter. This you will have to see for youself to decide. Then decide whether you are ok with the slight curve on the G4 that the G3 does not have. Roms will come in time but i see a number of people who are not bothered.
Have you seen the V10 ? will be more expensive since its 4GB and 64GB only. and the manual controls of the stills camera carry over to the video side as well. This right now isn't possible on the G4. The V10 is a little bigger though.
How much battery do you need ? mention your expected SOT/runtime.

I have H815 and have root, unlocked bootloader and flashed TWRP, please, get the G4. Getting a G3 is pointless. Think of the G4 as an optimised G3.

I had the g3 for a few days and it was full of lag and heat. Screen was also bad!
The G4 is a totally different phone. Everything about it is better except for size.

I did hear about the V10, of course, but that will, at least on release, be way out of my price range of about 400-500€ I can use from my employer. Also, I can't add from my own money because law restrictions and stuff.
Battery-wise, I'm quite the heavy user - I commute about 2 hours a day by bus and have the screen on almost all the time, but battery's not really a concern for me as I have a 13k mAh powerbank and the possibility to charge at work.
I was also considering a Galaxy Note 3 or 4, as they also have microsd and a swappable battery but meh, it's TouchWiz. Also it's a teeny tiny bit too expensive for my budget.

lG G4 slower than moto x first generation

Hello, i bought the LG G4 2 months ago, and I was really happy, I had the moto X 1 generation for 2 years, yesterday I use it to delete something to pass it to my mom, I noticed the moto x, faster in every single aspect (obviously no camera or heavy games) the normal use of the phone like, take it to check a mail, write notes, calendar, messaging, the launcher is faster in the moto x, changing between app is faster in the moto x, scrolling in chrome is faster in the moto x...
I have stock roms in both phones, same version. 5.1 not root or any kind of mod, no developers options, the animation speed is 1x in both phones...
The point of this post is ask, why if the moto x is an older phone with less specifications it is faster, and how can I make my LG G4 (h815p) faster like my old phone, now this think is making me crazy, why why why... >.<
If there is a problem with my English or you don't understand something ask me, English is not my native language.
Thank for the help.
I don't want to go back to the moto x, but I am really taking it in consideration...

You can use LGUP to upgrade to MM and test if it feels better. Any time you need to go to the repair, you can use it again to downgrade and they will never know what you did.

i will try with lgup i didnt know that this tool didnt need to have bootloeader unlocked.

to make sure this thread works for something, after using LGUP and installing Marshmallow on my lg g4 and using it for a whole day i can say that the phone is faster than before it was a really smooth boost, swithing beteewn apps is faster, its just a tap and is open, no more lag scrolling in chrome, everything is better, the only thing i noticed maybe cuz the heavy use is that the phone was hotter than before, i will check this tomorrow.

I had a moto x 2nd gen before I got my g4. The g4 is slower in almost every aspect. I even did a side by side comparison when I first got the G4. The processor that was in the moto x 2014 seems to be superior to the 808 in the G4. Just look at Andantechs reviews of the 808 and 810. They seem to think that they are problematic and that the previous generation 805 runs much better without heat, throttling or gpu issues. It also doesn't help that the g4 has a very heavy skin on top of Android. I may go to the moto Nexus 6 myself, not sure looking at alternatives to the g4 myself.
I am sure that rooting and changing the governor may help too, but I think LGs software couple with a junky processor make this g4 slow at times.
See the following link, scroll to the bottom where it compares the frequencies of phones where the paragraph starts "Looking at the frequency..". It will give you a breakdown on how the 808 works terribly in g4, flex and nexus 5x.

Do anyone regret after purchasing LG G4 and why ?

Hey everyone. I made this topic just to discover who regrey buying LG G4 and the reason why they regret. If they dont regret then please let us know.

Why?.I have it since a week and the phone is great,perfect.As an ex M9 user,the G4 is better IMO.
Waiting for 6.0.

No regrets after more than 4 months, you need a BT earphones for music as the 3.5mm is too low and some HTC ported apps to have a perfect UI (thanks Xpirt)

I didn't regret, but I do wish some things could be better (UI & Battery Life). Other than those, I've been relatively happy with my decision.
However, I installed the Resurrection Remix ROM last week and battery life is definitely better and the AOSP UI + CM13 theme engine is 100 times better than stock.

Which variant are you using? For most devices 6.0 is out there and you can manually install it (With or without root )
EDIT: To answer your question: No ragrets. Not even an "a" for an "e" :laugh: Best phone out there.
Came from a Note 4, love the G4 (stock) the most! Not as much bloat and nonsense as the note 4

I sold my G4 just for modding. I like to mod and unfortunately G4 have a small community. Good luck , best 2015 phone if you dont mind to be on stock.

only thing i regret about the G4 is the inability of most G4 variants to have an official unlocked bootloader ughh damn LG

I regret it and also not. I owned at least half a dozen android phones in the past two years, and the LG was the real bang for the buck with a very great camera. However, this was the only phone I had serious issues with.
H815 - First unit came with the display acting up (stuck pixel clusters), and finally RMAd it, when the motherboard died. I received it back repaired (PCB changed), but the display is now worse than before, the problem is, that it only shows after a few minutes of usage and probably they did not notice it. Stuck pixels + different brightness levels around the stuck pixel area. RMAing it again...

I don't really regret buying it, but if I were given the option again, I wouldn't chose G4.
My LG G4 is flawless. Battery is OK, no bootloops, no stutters/lags, etc. However, I bought it right after it was put in the market for a not-so-budget price and, for my needs, an S6 would've be better suited.
I mean... don't get me wrong. But as far as I don't need a spare battery/expandable storage, S6 would be a better choice. I just got tempted for the 5,5 screen and camera.

Im using H815T.My phone just boot up after flashing V20B KDZ with LGUP.6.0 looks smoother than LP.With V20C after restart comes up an error,but this error is not present with V20B.
Sorry,my english is not the best,that's why i do some errors.

I regret because I have weirdo half screen touch problem, it becomes crazy, but it's not a real problem, but there's still a problem so... and I don't have time to send it back, It does not have fingerprint sensor which is a shame for a 2015 flagship and it's plastic, we need some metal with leather...
But I bought it because of his camera, that's it.

have it for 6 months now (it is my only phone)
I regret:
- bad battery life (no more than 3h SOT)
- no unlocked bootloader / dead development scene (only a handful of ROMs, most are buggy and almost all of them are for H815 eu only models)
- bad sound over the earphones (really weak)
- no fingerprint reader (when all the other flagships have one)
- features that are essentially broken (still to this day), like tap to unlock

Lg v10 hands down would have been much better to have but lg g4 is still a great phone non the less

Overall i do regret.
I really liked the phone camera (front and back), screen, design and the option to remove battery and insert an sd card if needed.
But as i said before i never buy an LG smartphone again. They unlock the bootloader for just a single model and thats it. I like to customize and install mods on my phones, mainly to make it better, faster and that stuff, but my H815P cant be unlocked, and now here i am with a "Porsche that can't past 60mph"
Yet on the bad side, battery is not the best, some bugs even on the stock rom, and etc.
LG, never again. I prefer a not so good phone but that i can do whatever i want than this. Note 5 is the target now.

I moved to the V10 and I don't regret getting the G4 at all...because I still have it
These are similar phones spec-wise but in hand they are obviously quite different. I've had the G4 since July and just got the V10 a couple of weeks ago.
Already I keep trying to unlock the smaller phone via the non-existent fingerprint scanner lol!

No need to remain in stock, the community worked out ways how to root. But the biggest downer is definitely LGs position on bootloader unlocking. We can have Lollipop root without BL unlock, but no custom ROMs, no root for Marshmallow :/
It's my second Android, my previous one is a rather ****ty Galaxy Ace from 2011. So yeah, compared to that, Im happy with rooted 5.1.

cm13

Why not have cm 13 for lg gpro ??????

That´s the reason why my next phone will definitely be a Nexus...

Because our Cyanogenmod maintainer has not updated our phone's kernel (probably missing) and we don't have info on what google_msm kernel/CAF kernel repos or anything we need to update to MM..

I don't want to float anyone's boat, but E975 is much widely used... and is basically Nexus 4, so they use everything from there. S4 and M7 are much much more popular than this damn device, so yeah... that's pretty much why
I'm working on 6.0 bringup, but I have issues - not only from software side, but from hardware side too: my battery is slowly dying (and I can't find proper replacement), and looks like my usb board (or connector, let's hope its connector) died this morning, I can't do anything but charge it with all four cables I have and thats it... no serial connection means no data transfer, no adb access, no logs. It basically renders phone useless for any work.
I'm kind of sick of this phone, so I'm not sure I'll even keep this phone anymore... so my efforts towards M bringup are halted for undetermined period.

This phone is at the end of it's development life. We had a good run while it lasted. I ordered a Nexus 6 this week and will be moving on shortly. I'm keeping the E980 as a backup so I'll still try to tinker around with it but for daily use it is time to move on.

Why? I bought my G Pro last year for 240 euro brand new . Its in perfectly good condition, I don't see any reason to replace it . Screen is still fantastic, it has good enough performance, battery life is good - I menage to use it for 2-2,5 day.

While that is great you enjoy your device, the only reason we have custom ROMs on this device in first place is basically a complete hack, and also we have gotten no support from LG at all. All of this combined makes for a very unsatisfactory reputation for this device and hence why development is no longer very active and I do not expect it to pick up activity any time soon or ever (I could bbe be mistaken but this is just my opinion).

Yes, so sad for gpro

So, do you think the same level of support as the G Pro (i.e. minimal to non existent) can be expected on the V10?

Maybe not even that, because OEMs are getting really good about locking bootloaders and such nowadays.

Well as an owner of an E986 for about 2years 9 months and using it a lot of time every day I can confirm that this device is a beast, good performance, good battery,quality... and its like I bought it yesterday! Its so sad seeing G Pro slowly dying... I really hope it will be lucky with cm13

There might be a vietnamese marshmallow/6.0 project. @duongthinh441 mentioned it.

Thinking about buying the LG G4.. how stable are the custom roms?

So I finally broke my Galaxy S4 last night, and I'm thinking about buying an LG G4 to replace it. However, the LG UI "improvements" look awful, and I bet I would be changing the firmware pretty soon if I get it. So with that in mind, I'm wondering if I should be buying the phone. Is CM13 or other roms stable enough that replacing the stock rom a good idea on a new phone?
I'm also considering any any other phone in the same price range, including the Moto X Style (Pure).

Unless you're looking to get the T-Mobile (811) or the International EU (815) version, there is no way to install custom roms. Those are the only two unlockable variants.
The other versions are rootable if you stay on 5.1.1 LP, but if you want 6.0 MM, you'll be stuck with the T-Mobile or EU Int version. There is no way to root all the other variants on 6.0

Luckily, I would be getting the 815 version.

As far as I can tell the ROMs based on stock are very stable. You won't even notice the difference. CM and CM based ROMs are the usual. Stable but have a few annoying bugs. I haven't really tried any AOSP so I won't speak for those

Heres my opinion.i have a tmobile version and if i flasha custom rom it seems to drop the bands as i cannot get signal in places where i can on stock based custom roms or pure stock rom.it does not switch between towers properly and i lose the ability to make or recieve calls.when i check phone info on aosp or cm based roms it shows it uses only 4 of the 12 bands i have.

So I finally broke my Galaxy S4 last night, and I'm thinking about buying an LG G4 to replace it. However, the LG UI "improvements" look awful, and I bet I would be changing the firmware pretty soon if I get it. So with that in mind, I'm wondering if I should be buying the phone. Is CM13 or other roms stable enough that replacing the stock rom a good idea on a new phone?
I'm also considering any any other phone in the same price range, including the Moto X Style (Pure).

I made the same transition; from Galaxy S4 to Lg G4.
I'm running stock with Xposed. The G4 Tweaksbox app has a themes option and I've got a stock android one applied. It's really stable (I always expect themes to go crazy). The only other thing is the settings. You can get a stock settings mod but I don't really see the point. It works well enough for me and settings isn't really something you'd aim to be going on everyday anyway.
The clip tray is annoying but can be disabled. Add nova launcher and Google keyboard and it's all good. This is a much better solution than a custom ROM. You'll never get this kind of stability. Not forgetting that your camera app and fm radio and others will also be gone.
EDIT:
When buying, make sure the serial number starts with 601 or 602 603... These phones were manufactured this year so hopefully won't have the bootloop bug. If buying 2nd hand, ask the seller for the serial. If they can't provide it, ask for the IMEI and look up the serial number using https://imeidata.net/warranty/lg

There are too many references for 6XX bootloop issues, so I wouldn't recommend LG G4 at all , for custom theming,roms etc. Even after replacing motherboards of 5xx to 6xx, the bootloops are something more common than I used to believe...

personally am very happy with g4(601). best combo for me is Genisys Rom 4.2 + SimpleGX KERNEL (then Tweaksbox, xposed & nova launcher). very stable, no lags, speedy, good battery, amazing camera/lg app. downsides are unlocking bootloader voids warranty & the body corner feels painfully sharp after a while in the hand.

I am happy with the G4 too, 601 as well , but unfortunately that doesn't change the fact that there are many issues with the phone! I hope the OP can enjoy and proceed at his own risk of course!

Thanks for the replies guys! At the moment I think I'm leaning towards the Moto X Style, and will probably order it (at pretty much the same price as the G4) tomorrow unless someone talks me out of it.

I'll be honest with you.....my mom has this phone and has massive battery drain issues, where as I have none. If your going for good battery and fast updates than Motorola will be your best bud, but if you don't mind mediocre battery but a kick ass camera then the G4 will be your best bud. PS it's as good as point and shoot this is coming from someone that does photography for a living.

I also have little to no faith in LG anymore. Moving on to bigger better things but will ride it out until my upgrade is eligible.
Going back to Samsung, Motorola, Huawei or HTC.

Going to repeat this over and over again, i don't understand those people who after unboxing immediately install custom ROM (What!? you know what you're buying, you support OEM in this case LG, you support their firmware, skin and now you throwing out your money for something else in many cases worse, facepalm) if you want pure Android you buy Nexus, Motorola maybe, that's it, as Google says "Be together not the same". Installing custom ROM's it's like putting BMW rims on Toyota's car... beside that, G4 don't need a custom ROM, just imagine what your going to deal with custom ROM, awful camera, sound issue, lost functionalities, bugs, strange battery drains, degradation in overall battery life and everything for stock Android look? for latest security patches? themes? it's not worth it atleast now, IMO custom ROM's comes in handy when OEM stop's supporting your device with the latest firmware so if i done calculations right you should look for CM for LG G4 when Android 8-9 comes out. All you need is a root and good kernel then comes a good stuff, long story short, CM is a cancer for latest devices, flagships, believe me and don't think i'm condemning CM.

I used to be one of those who buys a flagship device, then immediately look for bootloader unlock, root and flash. But after having LG G4 for 3 weeks now, stock MM latest, installed with my needed apps and games, I lost the feel of flashing custom ROMs.
G4 is great as it is, although optimizations can be done, a little upgrade here and there. As long as LG supports G4 with updates and with their accessories, then I'll stay with LG as manufacturer. Of they abandon us (like what they did with G PRO), then I'll switch devices.
LG has been my favorite since 2013.

Be extremely cautious where you get your 815 from. I bought one from Value basket that was advertised as a European Variant for the express purpose of developing a CFW- When it came it wasn't and they refused to exchange it. I've got an email trail as long as your arm trying to get the thing exchanged but they're just con-merchants.
But it's still an awesome phone....

I do get your point. Buying the G4 would have been a compromise to get some good hardware for a low price, and I hoped to to sweeten that deal even more by customizing the firmware to my liking. However, I ended up getting a second-hand Nexus 6P instead. :victory:

Smartest move you could have ever made. LG has left me with a bitter taste in my mouth. Ever since I got my phone back with a new circuit board it feels like a ticking time bomb and I don't use it for anything other than texting, phone use and browsing. How pathetic is that.
