[LG V20 Questions & Answers] Archangel1183:
I bought this phone after changing over from Verizon to T-Mobile. My note 4 was really reliable and somewhat compatible with T-Mobile, but it didn't support some of the bands. Anyway, I immediately noticed the lag on this phone when compared to my Note 4.

After messing with several settings and doing a lot of reading online, I decided to try a different launcher and it made a huge difference. I'm currently using Nova Launcher. It takes a while to set it up exactly how you want it. I still found it a little laggy, but instead of the 7 seconds it took to open apps, it would take about 3. I then went into developer options and changed window animation scale, transition animation scale, and animator duration scale from 1x to .5x and apps now open and close almost instantly.
[LG V20 Questions & Answers] SMARTPHONEPC:
So how do you like the V20 now compared to the Note 4?

Agree even if can be hard to completely abandon your favorite launchers & some live wallpapers it's worth experimenting with other launchers-wallpapers & you could first try turning off those 3 animations in developer options to make it feel snappy or if you like them change them to .5x as suggested by Archangel1183. For laughs you could try all 3 animations to 10x :laugh:before turning them off or down as low as you like.:good:
[LG V20 Questions & Answers] slickdaddy96:
Any of you all with Sprint. If so I have sinking suspicion their crappy over saturated network is the cause of most of the lag.
[LG V20 Questions & Answers] jayochs:
nah, Verizon here. and i don't think it has anything to do with the launcher.. i've been using nova since day 1.
[LG V20 Questions & Answers] SMARTPHONEPC:
Just reread your original post & that does sound like crazy lag, are you saying when you're home (probably on Wi-Fi &/or with better signal?) not plugged in, the lag is dramatically less only or mainly getting that crazy lag when not in that environment?

How often do you reboot & what apps do you typically have running? Did turning off those aforementioned animations make it more snappy?

If you think it's doze you could try http://www.tomsguide.com/faq/id-3026187/disable-doze-android-marshmallow.html

Have you tried a different battery to see if it makes a difference on your battery drain, anyone recommend one like https://www.amazon.com/gp/product/B01MR3NHAK ?

Did you buy your V20 online or could you pop in a Verizon store to see if an exchanged replacement makes a difference?
[LG V20 Questions & Answers] jayochs:
yeah its mainly when I'm out and actually need to use it quickly, that's when it lags the most lol go figure. I'll check out that doze link. the battery itself is fine... usually it doesn't drain like crazy, but my new job is a metal building so it's awful on the signal. gotta airplane mode it! I have a us996 so I never played with any other version before.
[LG V20 Questions & Answers] jameslapc2:
I have found on my T-Mobile variant that if I run a AOSP ROM the lag is less noticeable and most of the time is less frequent.

Install magisk latest beta and try crossbreader in the downloads of magisk manager. It removed all signs of lag for me.

When I had this problem is was the wi-fi trying constantly to connect to every router in the area. I set smart manager to automatically turn wi-fi off when I leave home and back on when I return and haven't had a problem since.
[LG V20 Questions & Answers] KUSOsan:
You might want to double check as I have the T-Mobile variant and stock rom came with Facebook already installed. After disabling that and Lookout, it ran a lot better. Think there is actually a thread on here somewhere about those 2 apps lagging up the device
[LG V20 Questions & Answers] jayochs:
nah I've deleted Facebook immediately when rooted.
[LG V20 Questions & Answers] theleftykid:
you probably have frozen or disabled some apps that causes the lag. I actaully did a backup first before trying to uninstall or disable that looks bloatware to me. I disabled some LG bloatware apps that causes lag on my phone and camera. I don't know which is which but then I manage to install back my backup and start all over again.
[LG V20 Questions & Answers] jayochs:
I don't think i honestly touched any LG apps. I only really got rid of pre installed 3rd party apps. hmm.
[LG V20 Questions & Answers] jayochs:
that's it. I think I've officially had it with this phone. went outside to make a little video of the dogs for the first time in months, camera gets stuck on "saving" when i stop the recording, and the entire phone freezes. vibrate stops working, screen unresponsive. had to hold power and volume down for it to reboot and even upon reboot no touches were registered on the main screen for over a minute while the 2nd screen worked fine. this phone has officially become a pos to me within 6 months. guess it's time to look for something new or go back to my s7.

aaand tried using the S7 and that things an even bigger laggy pos. good god. why can't there just be a good, smooth android phone? I'm getting so sick of this. guess I have to look at the pixel... but not the new one since they're gonna be expensive as hell.

oh agreed about note 4...thats what, 3 years old now. it's much snappier. but it just bogs down randomly. some days I love the phone and it's great and flies, and then sometimes it just lags out

I have the H918 and have experienced no lag! I'm using a rooted stock rom and removed all the lg apps.
[LG V20 Questions & Answers] Still_living714:
I feel your pain lol but my V20 is ok(faster than s7e) I really think I will be switching to iPhone because I can't stand how slow they get real fast ?????????????????????
[LG V20 Questions & Answers] @rbiter:
V20 is smooth here. Even my note4 is fairly smooth still and I haven't tweaked it in months. The note4 lags occasionally and even gets janky but then smooths back out, well at least as smooth as a stock ROM would get. The V20 has and is still a pleasure to use. I have the occasional stutter but my iPhone 6S+ definitely stutters more and crashes a sh!t ton more. Never had a reboot on v20 and even went 2200 days without a reboot before I wanted to make a small tweak. That and I thought AdAway was broke, ended up just being a server down for about 30h.
[LG V20 Questions & Answers] evo4g63t:
Sounds like to me your issue may be a poor sdcard. Phones are very fickle with poor performing sdcards and when one starts to fail you'll notice your device will run like crap or will start to reboot randomly.

Try running the phone without the sdcard.

I've had mine since Feb and it has slowed down but that's just the nature of the beast all phones do this and is usually the result of more and more apps taking space as well as using memory.

Biggest annoyance for me is the notification bar it almost always hiccups when I pull it down the first time.
[LG V20 Questions & Answers] jayochs:
what kinda sd card do you use? I have a 128 pny in mine that's been fine since my s7 days.
[LG V20 Questions & Answers] KUSOsan:
I've actually heard about this before too. Even with the faster class 10 cards and up supposedly. Worth a shot
[LG V20 Questions & Answers] Archangel1183:
I apologize for the late reply. I've had the V20 for a few months now and I can see why LG's are so much cheaper than Samsungs. Although it has more memory and a faster processor than my old Note 4, it still has some random lag. The camera quality is about the same. To be honest, the only 3 things that I have found that are better than the Note 4 are the display screen quality, 2nd screen, and the rear button. The V20 has a nice bright white screen opposed to the slightly yellowish screen on the Note 4. The 2nd screen is awesome for notifications or quick access to apps. The unlock button in the back makes it easier to unlock the phone and apps with your fingerprint. One of the things that really bugs me about the V20 is that you have to scroll up or down to see the home touch buttons. I sometimes drag the notification screen down and have hung up several calls accidentally by touching the 2nd screen.

Seeing as this is a comparison between my old Note 4 and the V20, I'm guessing that a Samsung S8+ might be a lot better and I'll probably be upgrading to it in a few months.
[LG V20 Questions & Answers] SMARTPHONEPC:
Appreciate the reply & that use comparison. Unfortunately lag seems to happen with all Android phones eventually even with the latest updates, at least that's been my experience while multi-tasking (usually helped with regular reboots)..

"display screen quality, 2nd screen, and the rear button" are the main reasons I'd consider using the V20 over my Note 4. I actually prefer IPS for color accuracy, the rear finger sensor has got to be better than Samsung Note 4's terrible finger sensor & 2nd screen could come in handy. :good:

While the S8+ screen quality is great (although I'm not necessarily the biggest fan of its screen curves-aspect ratio, the brightness is impressive) it has the enclosed battery that Samsung has abandoned even after their multi-billion dollar Note 7 disaster. Replaceable batteries are very important to me & even with the recent hassle of professional battery replacement in my Nexus 6P's enclosed battery I find myself recharging it the same day too often..:mad:

Regarding "One of the things that really bugs me about the V20 is that you have to scroll up or down to see the home touch buttons. I sometimes drag the notification screen down and have hung up several calls accidentally by touching the 2nd screen", is there no setting or downloadable app that could resolve this-anyone?:cool:

I can't believe how snappy and responsive the phone is, though I did notice a definite improvement in performance after updating the werewolf kernel to basilisk.

h918 running NATF MegaRom 5 + Werewolf Kernel 2.0 (basilisk) + anti-throttling mod to improve performance/charging speed

I know there is a setting in the build.prop for changing the camera to always to show the navbar.

Have you tried messing with the settings in here? A pop up comes out saying there's a way to disable the feature of hiding it. The settings when you go into the hide home buttons setting but I clicked off it and now it is set to not show up again and I don't know how to bring it back to see

You running stock or anything modded? I don't really have a problem to the extent that it annoys the crap out of me but I notice lag from time to time. Usually when switching back and forth between apps a lot
[LG V20 Questions & Answers] @rbiter:
Don't get me wrong though I get the occasional hiccup here and there. Really hoping Android O is superbly polished. But compared to iOS right now? My iPhone has the hiccups.
[LG V20 Questions & Answers] jayochs:
lag always happens when waking the phone, when charging the phone, or at low battery. LG seems to scale down CPU power during all of these, which is annoying. this is why there's a noticeable delay for the screen to turn on when you hit power, knock on, or hold finger on fingerprint sensor unless something is actively running the in the background. doze on 7.0 is absolute trash. I get the exact same battery life I got on phones without doze, so it's nothing but a nuisance.
[LG V20 Questions & Answers] KUSOsan:
There is correlation between that as someone released a mod from remove the thermal throttle when charging and also Increased battery charge while screen is on as well. I have applied it on mine right and works great

Let's see how final Android 8 does vs final iOS 11.. I do hope Android O/8 battery improvements ( https://youtu.be/KRvBjbe8B8k?t=192 ) will also improve Android lag-hiccups-stutters.. so will/when the LG V20 get an official Android 8 update?

Also look forward to Android 8 integrated PIP: https://www.youtube.com/watch?v=NmSUvgGoWAY :cool:
[LG V20 Questions & Answers] evo4g63t:
Honestly I don't see android 8 improving performance.

The only two hiccups I have regularly is the initial turning the phone on from sleep (this could be waking up from doze mode) and the most obnoxious lag by far is the initial use of the notification bar. So annoying.

I don't see android 8 offering much of a performance improvement over 7 for this phone. I know it's going to be geared for lower end phones but will these optimizations apply to higher end phones?
[LG V20 Questions & Answers] Redline:
If you're rooted, use an app like Kernel Adiutor (yes that's the right spelling) to customize the kernel settings, I have it set to ramp up a low power core to half speed when it detects input on the screen or from the sensor, so that might help your problem. As for battery draining while idle, my phone drains no more than 2% overnight. Install App Ops and go through and set the "can keep device awake" permissions to denied.
[LG V20 Questions & Answers] maxi65:
Assalam o alaikum

The Lg v20's laggy behaviour is just because of thermal configuration which keep toggling the CPU's frequencies randomly to lower the speed of cpu and to keep the device cool also it is a Unwanted trick used by the Lg to make the battery life more than usual.

But the Good news is You can simply fix this by rooting the device and replacing the thermal configuration file.

I was having the same issue but after changing the thermal configuration the phone is smooth amd buttery even i didn't notice any lag after changing the file.

Steps:

Simply download the attached file

Use root Explorer to Access system and go to 'etc' folder and find a file named as themal engine config 8996 make a backUp of this file and replace it with the file you downloaded from attachment

And reboot your device :)

It is fixed in sha Allah

Note: the attached file is in txt format

Simply change the extension by renaming it from txt to conf and then replace it

Also the whole work for this configuration is Done by some other devoloper but i don't know his name :p

Here is a fix man :)
[LG V20 Questions & Answers] whitedavidp:
Hello there. I stumbled into this thread because I am new to the H918 and trying to work out all my many issues with the thing.

So far, I am stumped by a horrible lag that occurs, it seems, in conjunction with Nova Launcher. Most typically, it occurs after installing/removing an app and then pressing the back/home button returning me to Nova. This seems generally repeatable but not every single time.

I have tried all this with the default home w/app drawer launcher and it never seems to happen. I have tried everything I have found in this thread including disabling Doze entirely and changing the thermal config file. Nothing seems to help this.

In looking at the system logcat as quickly as I can after experiencing the lag I see long lists of lines saying "blocking GC NativeAlloc" that I do not seem to see at all if Nova is not being used.

I don't want to live with the default lauchers. I tried Apex but it doesn't seem to work right - I cannot drag an app out of the app drawer onto a home screen (WTF?) - so I gave up on that. I love Nova, have sent email to the developer. But I am not totally sure it is an issue with Nova. But it sure seems like something is going on.

That said, this device is (obviously) rooted, has xposed installed + a couple modules so it isn't stock (although the ROM was stock 10u before I started modifying things.

Any suggestions? Thanks
[LG V20 Questions & Answers] KUSOsan:
Definitely suggest mk2000 BTTF kernel as it runs better than stock and it already has the RCTD removed which is a must if you're rooted. I run Nova launcher and have never noticed anything specifically pertaining to Nova but had lag quite a bit on stock kernel. Back up your kernel in TWRP and give it a shot. There are 2 different kernels for the MK2000. I recommend the BTTF or it stands for Back to the Future kernel.
[LG V20 Questions & Answers] whitedavidp:
Thanks for this suggestion. I am eager to try it out. But have a couple questions:

1. I want to be extra sure my TWRP backups are protecting me in case things go south. I don't see a choice for backup up the kernel partition. I see Boot, Recvoery, System, System Image, Data (exclude storage...), Data Image (w/storage...), Cache, EFS, Firmware, LAF/Download Mode. Until now I have been selecting only Boot, Recovery, System, Data (exclude), and Cache. I am covered here? Is kernel in Boot, for example?

2. My rooted firmware is 10u on my H918. Is there a specific version of BTTF I should be using?

3. Is this just a typical, flashable .zip for TWRP?

Thanks and sorry for my noob questions.
[LG V20 Questions & Answers] Redline:
I'd start by trying a different kernel. Try D.O.T.S 1.5 from its thread (thread is titled v1.4 but there's a 1.5 download somewhere towards the end of it). Reboot to TWRP recovery, flash dots, wipe caches and reboot to system. When I was running stock the only kernel that ran well for me was DOTS, and it was the best experience I've had with the stock OS on the phone.

Alternatively, wait until the Oreo roll-out hits your device because that should improve performance. Or, if you feel like starting fresh again for a much, much better experience, join us in the unofficial LineageOS 15.1 thread for much better battery, smoothness and device overall.

DOTS + Nova was the best stock experience I've had, but LOS blows it out of the water. Instead of needing to rapidly press back after installing an app, why don't you try just pressing the home button and telling Nova to remember app drawer position in its settings.
[LG V20 Questions & Answers] whitedavidp:
Thanks very much. I just looked at the top of the DOTS thread and it says "It can only be used on H990". I see this is the model you have. But mine is an H918. Also, not rooted with Dirty Santa but with lafsploit - if that makes any difference.

Either way, before I fiddle with flashing anything, I want to make sure I am covering my butt using TWRP backup properly. Any idea which partition the kernel is in on these phones (as shown by TWRP)?

Thanks
[LG V20 Questions & Answers] Redline:
Ah sorry, my bad. Been a while since I ran stock haha. In your case, you'd be best off running mk2000 kernel from HERE it appears it works with the lafsploit H918 from what I can see.

Kernel changes are generally on the system partition in TWRP, so you want to make a backup of that at the very least before flashing anything that modifies /system (like a kernel, xposed, Magisk, etc.) but for safety, I backup everything including Data except for System Image and Beta: Data Image w/ Storage. This ensure if I needed to, I can restore my SystemOS, Data (apps) and other partitions the phone needs to function, but not /data/media which holds all user things like Downloads, Pictures, etc. It's generally a good idea to have backups of EFS/Firmware/LAF as well, just as a last resort if your phone bricks.
[LG V20 Questions & Answers] KUSOsan:
1. Correct. Boot would contain your kernel

2. Just which ever is the latest for the H918. Should say beta_1 at the end of it

3. yes you just flash in TWRP and I think wipe cache and dalvik. Not sure if it's necessary but I do anyways.
[LG V20 Questions & Answers] whitedavidp:
Ok, I have taken the leap and flashed the beta_1 kernel for H918. The flash went fine. Wiped as well.

When the device rebooted, it seemed stuck at the TMobile logo. I was worried at first but then recalled a similar long (like 20 minute) delay after installing xposed. So I decided to wait thinking that maybe xposed had to do its thing again. Patience seems to have been a virtue and the device got to the Android is starting screen. This along can take some time to complete. Again, I recall that from the initial xposed install. Finally, it reached 100% and the device is running again. So others with xposed, take note.

I was not aware of the RCTD until it was mentioned here. Not sure if that has been the cause of my grief. Hopefully my results now will be better. I will report back.

Meanwhile, thanks very much to all who responded.

PS - well that didn't take long. While I had not used the new kernel very much, I was suddenly having troubles where I had none before - for example when inputting via keyboard. Not sure why. But am flashing back TWRP backup now. It could be some mod I have installed/made. Cheers
[LG V20 Questions & Answers] KUSOsan:
I would chalk that up to Xposed. I used to do Xposed back on the Galaxy S4 days when it was much more commonplace. Nowadays I haven't ran xposed yet on the V20 but ive read plenty of compatibility issues from other users with little stuff like what you mentioned.

There is a thread that had stock kernels already patched without RCTD. Search for the main RCTD removal thread.

Otherwise if I were you I would try uninstalling Xposed first and then do the BTTF kernel and then reinstall the Xposed after to see because the kernel has made that big of a difference for me. Maybe do magisk if you haven't already so you can do the Xposed modules for easier switching on and off.
[LG V20 Questions & Answers] whitedavidp:
You may be correct about Xposed. Hard to know, I guess, at this point.

I did find an app that says it has removed RCTD and run that. It reports that it and Triton (whatever that is) are not found. Ot does say that CCMD (again, whatever that is) is running. But it also says that removing it can cause bootloops so....

Regards Nova, I managed to get Apex installed and working (would not at first for reasons unclear), spent a bunch of time configuring it and my home screens. For a while, I saw no lags like I did with Nova at more frequent intervals. But I did see something similar happen. So I am thinking it is not Nova (or launcher) specific.

I am rather surprised by all of this. For a device with far better specs than my old Note 3 (with Samsung, not Snapdragon) on Android 4.4.2, I have basically the same apps installed, the same configurations, the same mods, etc and performance is only about equal - until it lags like this. I have even gone to the trouble to completely disable Doze, change thermal settings, etc and still have this issue.

I really want to like this phone and Android 7. But I cannot say that I am convinced at all. This is too bad.

Cheers
[LG V20 Questions & Answers] KUSOsan:
Yeah the RTCD removal app I believe is still broken. The newer app only removes the extra 2 things and an you have to find an older release that removed the actual RCTD. That's why I didn't mention it earlier. Unless he fixed it. I'm subscribed to the thread and don't remember seeing any updates.

I agree about the phone in general. Certainly a lot of hoops to jump through just to get this phone to work like an actual flagship phone lol. Although it's a fantastic phone once you get it working properly. I'm running Alpha ROM and the little extras to the 2nd screen like being able to add more shortcuts make this phone worth it even though it was just a one off.
