[Google Pixel 3 Questions & Answers] JasMan78:
This is exactly the issue I have now, too.

Before the April update I had a lot of more flashes. When the AoD setting was enabled for some days, the issue also occured on the waked up screen. Sometimes 3/4 of the screen got green/white-flashing with small lines from the top to the bottom on the whole screen. I had to disable the AoD setting to solve this issue. With disabled AoD setting everything was fine.

Since I've installed the April OTA on Monday, I've also enabled the AoD setting to observe if this issue on the normal screen comes back. But until today everything is fine....except this single flashes when the AoD screen becomes active.

Same issue, just started today.

On May update
[Google Pixel 3 Questions & Answers] mikeprius:
Well, with Android 10 naturally I had to try this and see what happens. If I toggle AOD, then press the power button twice, the screen does not flash and works how it should.

Only took 1 year and a new Android version, but it appears that it is gone although Google could always bring back the screen flash as an Easter egg

Yep, that's the issue.

For me the update in March (April?) solved it.

So I got the P3 two weeks ago and yesterday I started getting issue 1 mentioned in this thread. I have now had to disable AOD as a work around. Not super happy...

[LG V20 Questions & Answers] dougdraws:
Looking at purchasing a V20 and just wanted people's opinions on the phone (those who already own it and are using it). I can get a new one for $230 from a legit seller on eBay so I'm seriously considering it. Right now I have an iPhone 8+ with AT&T but I'm missing my Android and it would be nice to have a user replaceable battery and not be stuck with a phone whose battery dies after 2 years or so.

I'm also wondering which model to buy? The new one on eBay is a H190, but I've read in places that the US996 is also a good model. I might actually consider rooting this phone so which model would be easiest to root?

Thanks.
[LG V20 Questions & Answers] Foreigner1:
Honestly, I would never suggest someone to buy the LG V20. And since you're currently an iOS user owning an 8+ this would reinforce me to not suggest the phone even more. I own a V20 (H990DS AME) & I'm using it to write this. It's been with me for almost 2 years & boy it throttles A LOT. I'm still on Android nougat waiting for the Oreo update. Other V20 models have gotten the Oreo update (Verizon, AT&T, All international H990DS except AME I think etc.). So to summarize things up, I do not recommend this phone as it will be a pain most of the time i.e. cons >>>>>>>>>>> pros. Screen burn ins, too much lags, bad battery life, slow performance, extremely slow software support, laggy camera, outdated design (at least that's what I think now), and the useless second screen that LG THINKS they implemented the software correctly for it (Oreo doesn't change the way it works, meaning it's still the same) >>>>>>>>>>>> Hi-Fi Quad DAC (The only good thing I can think of in the V20).

PS: NO root for Android Oreo on the V20 since it just came out 1 year late woohoo! So you'll have to wait until a root comes out.
[LG V20 Questions & Answers] zeusofyork:
Here's the deal. If you plan on rooting your phone...get it. Custom ROMs really make this phone shine. Us996 is unlockable and rootable. The H910 is rootable up to a certain point, double check on that as it's not my model. If you're going to keep the phone stock..it's OK. You're going to get some lag over time. I'm on an LS997, rooted it was great (broke that one), and now I'm on stock ? Oreo. It's good for a daily driver for the most part. Love that I can pop and swap batteries as well as sd cards -- quad DAC and ir blaster are also a big plus. Long story short, it's ok stock but you will deal with screen burn (pretty much fixed if rooted) and lag. I know iOS is pretty solid and is fluid, but the things I CANT do with that phone drive me absolutely nuts. That's why I always go back to Android. If you root your phones definitely get it. Can't beat the features for that price brand new. You can pick them up even cheaper used. The guy above me obviously didn't root his phone and I'm sure he'd be singing a different tune about the phone if he did. I say get it, especially if you're gonna root it. If not it's a decent option for the price.
[LG V20 Questions & Answers] tech_infinity:
I agree with this. Wouldn't recommend it either. You'd be better off with another device.
[LG V20 Questions & Answers] zeusofyork:
Have you even considered a custom ROM? All of your gripes are pretty much eliminated by using one..

---------- Post added at 12:54 PM ---------- Previous post was at 12:52 PM ----------

You're on stock?
[LG V20 Questions & Answers] tech_infinity:
No. I've tried custom roms. Things are a lot better with them.
[LG V20 Questions & Answers] Foreigner1:
No actually I haven't tried custom ROMs, and I don't know much about them. However, recently I did start looking into them, but as I can see that installing custom ROMs will remove some functionality in the V20. Things like the second screen &/or the fingerprint scanner (Also what about the Hi-Fi Quad DAC? Will it still work?).

What custom ROM would you suggest as the best one for the V20 (H990DS)?
[LG V20 Questions & Answers] dougdraws:
Thanks for the replies everyone. So if I wanted to go back to Android can you recommend a good phone? I hate the new curved screens on everything and it seems all the phones are starting to look alike. I should have stuck with my Note 5, but oh well live and learn, lol. I was only considering the V20 because of the replaceable battery, SD card and of course Android.

Just out of curiosity, what's your opinion on the V30?
[LG V20 Questions & Answers] zeusofyork:
Those only apply if your using an lineage/resurrection/aikp ROM and from the last I read lineage has second screen support ...ish. I think there's a way to get quad DAC working in lineage too. You'll have to read it though. I can't root my phone because of ARB but before I broke my last v20 I loved running custom ROMs . If you use a stock rooted ROM you can debloat and tweak the system for performance. Again on custom stock based ROMs all features still work. Go through the ROM recovery thread and look to see what works best for you.

---------- Post added at 03:48 PM ---------- Previous post was at 03:47 PM ----------

No second screen no removable battery...meh I'll stick with my v20. Like I said if you root it and put a custom ROM on it's in my opinion a far better phone than those available. The newer ones may have water resistance fingerprint scanner in screen etc...but those arent what made me choose a phone. The v20 has everyhing i wanted. As the v30 I hear it's a decent phone.
[LG V20 Questions & Answers] dougdraws:
How difficult is it to root the V20? I'm a complete n00b when it comes to rooting and from little I have read on it, it seems quite daunting.
[LG V20 Questions & Answers] zeusofyork:
It's not incredibly difficult. There's literally a thread with step by step instructions. It was harder than rooting my note 5 and note 4, but impossibly so.

[LG V20 Questions & Answers] masondoctorjt:
The v20 is a very nice phone. In fact I bought another one. It has a SD slot, 64gb onboerd, IR blaster and removable battery. It's worth it just for those features. Mine does not throttle. Neither one does. I just wish people would not buy phones that take away features, it just encourages the phone makers to keep taking them away. As a result, next time I buy a phone, I'll be forced to but an inferior product to my v20's [emoji852]️
[LG V20 Questions & Answers] tech_infinity:
Just out of curiosity, what's your opinion on the V30?[/QUOTE]

I actually have a v30 plus at home and it's amazing. Display is gorgeous and an AMOLED panel. Battery life is good. Camera's great. Has HiFi DAC. Doesn't have screen retention issues.

The reason I'm not recommending v20 is because it's a 2016 flagship that doesn't really perform like a flagship on stock rom in terms of performance. It probably won't be getting Pie update.

For 230 dollars, if you don't mind rooting, it's a good device.

What's the cost at which you're getting V30?

Though it doesn't support removable battery.
[LG V20 Questions & Answers] Ak7J4:
Rooting on the H918 (T-Mobile) version isn't that hard. You use a FWUL (Linux) and run 3 commands. Really easy and safe. The other models can vary but if you know how to use cmd even a little bit, it shouldn't be that hard. If you need help just ask on here.
[LG V20 Questions & Answers] Redline:
FYI: https://xdaforums.com/v20/development/rom-h990ds-oreo-flashable-t3853735

There's flashable Oreo stock and custom rooted ROMs available for almost every variant.

Also, all of those problems are eliminated by a custom ROM and Kernel. It's a process, yes, but the phone essentially becomes something else entirely.

Also also, we've got second-screen support on ResurrectionRemix (this is most up to date) and LineageOS, both with the stock ROM kernel or a custom one (I maintain the second-screen Gamma kernel).

The DAC/Camera/etc. all work as they do on stock.

[LG V20 Questions & Answers] One Twelve:
Bottom line

Amen

What's happened is at some point the customer stopped mattering any more only the company stock holder. All these companies copy things that make Apple suck they never try to emulate what makes Apple great.

I'm on stock since i didn't want to bother with rooting. The phone does what i want. I don't have screen retention since i have brightness down. I suspect its caused by high brightness all the time. Some people can't see the screen unless its 70% bright. Mine is usually in the 20s or 30s unless its outdoors

I got it because of the camera i had on the G4. Liked the interface. The wide angle is useful. Starting to be copied by Samsung & Huawei

I don't use headphones but I hear its got a good DAC. Reason i don't have headphones is because increasingly where would i plug them into in the future

Still on N, and everything works fine. I avg 4-5h SOT on wifi and a spare will double that in a snap. No high end phone can match that and likely never will. Mid rangers with 600 series CPUS & thick batteries might.

I find the second screen useful. Only way to quick launch the camera while listening to something

I'm not too bothered with speed. Computers spend most of their lives waiting for people to tell them what to do. This phone runs cool maybe its because it throttles past a certain temperature. That's good as i live in the tropics and it can get warm here.

I'm actually nervous about Oreo that it might break something so i'm not in the slightest bit bothered about not having it yet.

Is there any progress or hopes on rooting the ls997 running Oreo?

My device was unlocked for any carrier but after the Oreo update it has been relocked and I can't seem to find a way around it.

Rooting seems to be my best bet now. Plus I need to delete some super annoying Sprint apps.
[LG V20 Questions & Answers] Mysticblaze347:
I would say if you mean official Oreo, than no.

Anything after ZV7 atm is not rootable. Especially Oreo. Nougat might still have a chance. But Oreo is the nail in the coffin, if not the final nail. I personally am rooted on ZV7 and I can't even find an Oreo based ROM to run and try for LS997. Sprint's Kdz lockdown is my guess.

Carrier unlocked is sadly not going to allow root either unless somehow able to fully swap internal thoughts and memories of phone with another carrier. Even if able, it a slim chance if any.
[LG V20 Questions & Answers] zeusofyork:
You ever find anywhere else with a zv7? The one you linked got snatched up...?. I gotta make a dump for i95swervin and maybe he'll make a version of Alpha Oreo for LS997. I might be responsible for your lack of an Oreo ROM ?

We should start a bounty thread???
[LG V20 Questions & Answers] cnjax:
A bounty thread would be useless, most of the devs have moved on and runningnak3d has already stated root for 997 is a lost cause. If root is very important to you, then you should move onto another device
[LG V20 Questions & Answers] Mysticblaze347:
I would be down for a bounty thread, but I think it would be pointless as well.

As for the ZV7... That sucks. I wish I had another link but I do not atm and can't say when. If I see something I will let you know asap. Very rare now adays.

I also have a ZV7 dump I think on my laptop if need be from before I rooted.

ZVD rootable would be absolutely epic, I still have hope for someday as for my backup phones.
[LG V20 Questions & Answers] C D:
The eBay store of the seller who previously sold several LS997 ZV7's can be found here. He periodically relisted the Sprint LG V20 on there over the last couple of months (I bought two ZV7's on two separate occasions), so there's a slim chance that he could still have another ZV7 left among those that he sells. You could contact the seller to check.
[LG V20 Questions & Answers] runningnak3d:
As I have stated in another thread, I have a procedure that I am confident will work, but it will require significant development time to get kexec working.

The procedure would not be easy (if you think lafsploit is hard to do .. you haven't seen anything yet). Also, it would be a tethered root .. meaning you would need a PC every time your phone is powered off. If you just needed to restart the OS, that could be done without a PC, but a cold boot would need a PC to enter some commands via a shell.

If all of that sounds like something you are willing to deal with, then start a bounty thread and I will try to get an exact estimate on the amount of dev hours I would have to put into writing the code.

If you Google "kexec loading a kernel from a kernel" you will get an idea of the amount of work I would have to put in.

By using kexec, we would use a validated kernel (one that passes dm-verity) to load another kernel with dm-verity disabled. Since the first kernel already passed the checks .. the second kernel would be loaded without the full boot process, and therefore aboot wouldn't verify it.

EDIT: Oh yeah, you would also need an SD card in your phone with a partition to hold kexec, the kernels, and TWRP. You could use the rest of the SD card for the OS, and the partition wouldn't need to be very big .. but just throwing that out there.

[LG V20 Questions & Answers] Mysticblaze347:
I never looked into lafsploit because I don't have an H918. Just ls997..one rooted ZV7, and two ZVD's (backups). However...that method would seem a lil tedious, but doable. If only way...

I was wondering if it is even possible or easier to do and full on 100% phone clone. Turn one of the ZVD's into the rooted ZV7. That would be a true game changer and way faster.

If this was not intended at me I apologise. However, just a thought.
[LG V20 Questions & Answers] runningnak3d:
Once ARB has been incremented you can't roll back to any version that has a lower ARB. Even if you replaced the NAND, you would still only be able to use ZV8 or later since ARB is incremented inside the CPU. So, you can always replace the CPU AND the NAND :)

-- Brian
[LG V20 Questions & Answers] Mysticblaze347:

Sad year so far

My beloved fully rooted ls997 died with a sudden rpm crash that was unfixable ?. Cant find a different one for the life of me. Anyway, I am now on ls997 oreo with temp root. Its nice, but very limited. I miss my full root.

I noticed that I have oem unlocked which is supposed to unlock bootloader or allow. But this supposed arb screws it up. How I have no idea. Its all rom related so it absolutely makes no damn sense. Why have oem unlocked if we cant do anything?

So oreo full root with arb?...

Would a stock Oreo dump allow for kdz extraction to make a rooted/ rootable rom?

Just a question and be cool if so. Long shot I know.

Especially with a not yet known arb bootloader

Including unable to unlock phone, deep sleep issues, and random behaviour.

Also fixes overheating and battery issues as well as makes GearVR work without heating issues.

This is a hardware fix and so far has been 100% effective on all devices I have repaired,

Its an easy repair and takes about 20 to 30 minutes to complete.

No special tools are needed and I have posted a video below to show how this is done.

All you will need is a bank card or spudger, a pair of scissors and some cardboard from a cereal box.

You may also need a drop of glue or blue tack.

Although this usually stops all issues on most devices you may still need wakelock but usually it's not needed.

Anyone attempting this please do not go under the glass try push it forward from the battery compartment and then run a card around the edges of the grey plastic. Just go carefully when doing this and don't rush. You can heat the screen with a hairdryer to make removing the phone from the casing easier. It's the best way to do it.

Also you could use Aluminium Thermal pads or Copper instead of cardboard for better thermal cooling. Just make sure its 0.5mm or 1.2mm thick but no thicker!

You will get great 3d mark results using Aluminium, Copper or Thermal pads. "Do not use any kind of thermal pastes!!", You have been warned! But even using just cardboard works great as well.

Don't blame me if you break your phone more by attempting this. But if your phone is not working, you really have nothing to loose. :)

If you have an old phone you would like to donate please send me a PM. ;)
