Lockscreen wallpapaer rendering - OnePlus 3T Questions & Answers

Hi All, i want to explain my "problem". I use Nova launcher every day and when i want to set same wallpaper for lockscreen and home screen i need to do it with the gallery because the oneplus wallpaper picker can' t be used. Now if you see in my screenshot the wallpaper in lockscreen seems like it has some imperfection in color and resolution, but in nova home is perfect ! There is a solution? Now with this wallpaper the problem isn' t really evident but with lighter wallpapers the result is horrible... Hope in a solution

If I understood correctly, I have the same problem with Nova Launcher: it seems the wallpaper gets scaled once you set it, no matter if it matches your screen resolution or not, generating artifacts.

[Q] Low-res (bad quality) lockscreen wallpaper -- How to change it?

As you guys might have noticed, whenever you set a wallpaper using the default android gallery, it kinda compresses it and results in a low quality version of the pic as your wallpaper. I've found a workaround for this by using apps from the market to set my wallpaper with BUT all of those apps can only change my homescreen wallpaper and NOT the lockscreen wallpaper.
So my question is if any of you guys can tell me how to manually change my lockscreen wallpaper? I have a rooted device 2.3.5 btw. Thanks.

No, I know how to change the lockscreen wallpaper. But like I've said, when you use that way, it lowers the quality of the picture you use. If I use a hi-def photo and set it as my lockscreen wallpaper, the quality loss is very obvious. Which is why I was asking if there was a workaround for this.
When you're about to change the wallpaper and the square box pops up, tap it and expand it.

no, that's not it either. regardless of how you crop it, if you use the default gallery app, the resulting wallpaper is compressed thus the quality loss
get a suitable hd wallpaper from the internet then save picture to gallery. When you set wallpaper to lockscreen choose gallery, find pic you have d/l and crop it accordingly. Remember to get the highest resolution wallpaper.
Hope the above helps

+1 to the question!!!
I wanna use the same wallpaper on the lockscreen & on the my launcher. I choose the picture, set it up as my wallpaper - in the laucher it's absolutely ok, but in the locksreen there are a lot of strange lines (bright & dark) over the wallpaper.
you need a wallpaper of atleast 1600*1000 resolution. If you can find one with an even higher resolution, better still.
Just follow instructions of my earlier post

Of course I have a high-res wallpaper!
But the quality is much worse on the lockscreen than on the launcher's homescreen.
Maybe light wallpapers are ok, but the dark (like mine) is laggy.
anyone knows where the default wallpapers are saved to? cant seem to find the default lock screen wallpaper (of the pen and notebook)...
low resolution for a purpose
do you think the lock screen uses a lower resolution for a reason. that screen basically is displayed for just a few seconds and kinda floats on top of an already high resolution main screen. just a theory that it's supposed to be lower quality graphic.
You can use Quickpic which is free on the market to set the lockscreen. I don't see any reduction of resolution.

again guys, the issue is not with the cropping or with the image quality i'm using. it's with android gallery app compressing the picture i want to use.
@holgalee
thanks, that was exactly what i was looking for!
How about WidgetLocker? A guy posted a screenshot of his completely black background that didn't have any of the ugliness many are reporting of. But it costs money, and i don't know how you feel about apps that cost money, but you're holding a device that cost almost $1000
same problem here.
tried to have a black background on the lockscreen.
tried with a 1200x1600 bmp, png and jpg...
always the same ugly green and black stripes
none of that with galaxy s1 and s2, just with the galaxy note
what can i do to have full black background? dont want to use crappy alternative lockscreen, want to use the native android lockscreen
It won't help with a 5500x3500 wallpaper as long as the default gallery app is compressing the image. It will still look like ****.

I had the same issue on my S2; completely stupid really. Now I have my lockscreen wallpaper automatically change when I modify my [active] wallpaper.
The Gallery app needs to be fixed.
It's still crap on the note 2, anyone who's found a solution?
If it is the black clipping problem? Note shows lockscreen wallpaper a bit darker than normal wallpaper so theres possibility you only notice it on lockscreen.
Found one that looks okay so i am using that

Help on Nova prime launcher

Hi.
I am facing issue with Nova Prime Launcher.
Below are the two screenshot. One on TW and other on Nova.
My question is why nova is hiding sides of my wallpaper. A big area is hidden which makes my wallpaper ugly.
Any idea how to correct wallpaper alignment on Nova.
Regards
Mani
Hmm...seems like the wallpaper on TW uses only the visible section of the screen, whereas the wallpaper on NOVA uses the entire screen resolution thus looking zoomed in.
I suggest you use Wallpaper Wizardrii to play around with wallpapers
You'll get tons of options to help you keep the wallpaper the way you want it.
I hope this helps!

KLWP & Nova Launcher - Wallpaper Scroll Issue

Hi guys
I am reaching out to you guys because I haven't found an answer in the world wide web and probably some others would have the same problem as I have.
I recently installed KLWP app to customize my wallpaper. Problem that I am facing is that with no used Launcher (Nova, Apex, Evie) I can make my wallpaper scroll. Option is always on and I also checked that I have the same amount of pages in KLWP and my home screen. Not even with the standard launcher of P20 it's possible.
Does someone of you have a potential solution for me?
Thanks a lot for your help and best regards from Zurich
No solution, but the same problem on a P20 (not Pro). Tried to set a picture as wallpaper in Nova Launcher, but scrolling doesn't work. I also tried to force scrolling in the nova settings, but this crashes Nova.

I have a potential solution for you. I have had exactly the same problems like, as it seems, a lot of other Huawei users and nothing seemed to work. I then installed a bunch of different launchers and I finally got it working with Action Launcher. It worked out of the box, even tho if I made changes within the action launcher the KLWP became static again. I switched betwwen stock launcher and Action Launcher until I had my KLWP set up with all the settings I needed. You have to play around with that a little I guess, but I really think it will work for you.
The Launcher is this one.
Kind regards from Germany!
has there been any solution or work around for this? as i have a pretty cool setup i used for my previous sony xperia z2 and want to use it form y p20 pro but wall paper scrolling is integeral to it.
When you choose wallpaper click on the scrollable icon so it turns blue, your wallpaper is now scrollable when you apply it
I did the scrollable option in the standard launcher and it worked but I'm more interested in getting it to work using nova launcher. That's where everything seems to break down on me. Using standard everything works the way I want, just to complete the setup, I need to fully customize my app looks and shortcuts.
Same issue with Honor 10. Force scroll option on Nova Prime crashes the launcher.
Do you have the ability to select live wallpapers through the normal stock launcher?
As I've noticed on stock launcher the only live wallpapers you can see are the ones through Huawei's Theme App and no option to use external live wallpapers, so I wonder if this is the problem. I've emailed them and just waiting for a response as they state you should click on 'more' and then get option for live wallpapers in top right screen of which I don't, it's only the huawei theme app
Wallpaper scrolling works for me using Nova. I can also select external live wallpapers using Huawei's themes app.
If I use certain wallpaper apps to apply the wallpaper directly from their app, it doesn't work. But I found that once applied, I can then use nova wallpaper selector to reselect the same wallpaper from its 'history' options and this forces the wallpaper to now scroll.

I was on 156 and now on Android Pie EMUI 9. Scrolling still works for me. Stock theme.
On my side, i try to disable the wallpaper scrolling because when i set a static "portrait" picture, it zoom the picture and it's a mess >_< (nova launcher set in static wallpaper)

So you are on a totally different model/firmware as not all P20 Pro's are the same, it doesn't work on the CLT29-8.1.0.131 (C782)
Update: according to Huawei 3rd Party Live Wallpapers are not supported.
In response, please note that Google live wallpaper, KLWP or any other non Huawei themed live wallpaper are not supported by the device

I've not gotten Nova Launcher Pro to work. As others have stated, if I select Scroll Wallpaper to On, nothing happens. Just a static wallpaper. If I choose forced, it crashes.
The Microsoft Launcher works fine however. Just set a regular wallpaper to scrollable in the Huawei Wallpaper app, then you can apply KLWP. This has worked for me at least. The drawback of the Microsoft Launcher is that it doesn't have the workaround for the 5 second delay which is a pain. I've reported the issue to Microsoft a few times, both on the Google Group and Twitter, but so far, nothing.
SOLUTION :_Wallpaper scrolling in klwp
Its simple.... If u have 3 screen klwp live wallpaper jst save it from klwp and come to home screen(hope you have nova) then hold the screen untill it arrives to add screens.
Add 3 blank screens and feel the magic of klwp.
U must also enable wallpaper scrolling in nova settings

Lockscreen notification drawer lag after Android 9 update

I noticed if I use the default infinity wallpapers, when you swipe down the notification drawer from the lockscreen it's a smooth animation
However when I use a different wallpaper, even the samsung wallpapers as long as it's not infinity branded, swiping down the notification drawer from the losckreen is jittery and slow. It doesn't happen on the main home screen. Only the lockscreen
Anyone else having the same issue? Mine's an Exynos variant Note 9
Yes I have noticed It too, i wonder if there is somthing to do about it..

I've downloaded the Walloop Engine app from the Play Store, which gives you the ability to set the live wallpaper as your homescreen/lockscreen wallpaper. For some reason, lockscreen notification drawer doesn't lag if you set a live wallpaper. I have no idea how Samsung managed to produce such a silly bug with static wallpapers.
I also have found that if you set your screen display to WQHD the animation on the lock screen will be laggy and will stutter and even sometimes on the home screen itself and if you put the screen display on FHD+ the animation will run smooth.
Check it out and tell me If the same problem happen to you too.

I notice this issue only on lockscreen, but yeah, it happens only on WQHD resolution and only with static wallpapers. Infinity wallpapers and live wallpapers are not causing any issues, regardless of resolution. So, to sum up:
HD/FHD resolution: no lag, we can use any wallpaper
WQHD resolution: notification drawer lags with static wallpapers, but doesn't lag with infinity/live wallpapers

Wallpaper Set Issue

Some of you may be familiar with my typical home screen layout and custom wallpapers that I make on my PC. Well, I'm now experiencing issues with applying wallpapers to my home screen. Everything is slightly off, and not aligned properly. It appears that the phone is "zooming in" the wallpaper as it sets. Like, I'll have a border separating the notification bar area and my home screen but when applying the wallpaper that border is moved further up into the notification area. Like I said, the wallpaper seems to be "zooming in" as I set the wallpaper to my home screen.
I'm using Nova Launcher Prime. 12x12 grid. No dock.
I tried using Apex Launcher and ran into the exact same issue.
I've restarted the launcher. Restarted the phone. Used different photo apps to apply the wallpaper to the home screen. Nothing has fixed this. I'm not sure what else to try. If anyone here has any idea on why wallpapers are distorted (zoomed in a bit) as I apply them to my home screen, please help. Thanks!
ETA: Added two screen shots with a specific wallpaper that I found online to help show you what I'm talking about. When I see the preview of what setting the wallpaper will look like, it doesn't apply that way after setting the wallpaper.
Sweet, baby Jesus! I found the solution!
Please let this be a PSA for everyone who may run into this issue. The culprit was that stupid "Motion Effect" option while using the One UI launcher. You have to make sure when switching back to it from a third party launcher like Nova that you choose the "always" option so that it's your default launcher (stock launcher). Then when you do that and choose to apply a wallpaper, you'll see the "Motion Effect" option right under the image. Uncheck that stupid thing and your wallpapers will not longer "zoom in" like they did before.
Now, everything is lined up as it should!
