Apps ghost lingering on screen after close - Samsung Galaxy Note 20 Ultra Guides, News, & Discu

My note 20 ultra is having an issue where certain times when I go back to home screen, the app I was on leaves a ghost image on the screen. Only way to seem to get rid of it is to reboot device. Have to do this once a day. Tried with Nova and One UI but no dice fixing without reboot.
See my screen shot. Is there another way to refresh your home screen a la Windows?

Stability of Nexus Launcher/Launcher2

Hi all. I've just been wondering... has anyone else besides me ran into countless problems using the Nexus Launcher/Launcher2 on their phone? I'm running Fresh 2.0d with the included .apk, and here are some bugs I've found:
Unresponsiveness
Screen turns black and stays black requiring a battery pull
Launcher will launch without displaying icons in the menu
Now, it is not only Flipz's ROM that has these problems either... it is EVERY ROM I've tried. I'm sure most of you will tell me to use Helix Launcher. I have tried it, but it doesn't have the same feel that the Nexus Launcher has.
Has anyone found a fix for these stability issues? If not, I'd like to start a project so we can get this working, because I'm sure it's completely possible. After all, Flipz was able to get the 2.1 lockscreen working!

I am running fresh2.0d and stock screen turns black and needs battery pull when I use camera app and hit back button or any button.
Launcher has been pretty responsive except here and there....
I do get to the mode where no icons on home screen for few seconds at times but it recovers pretty soon....
As far as the lock screen, I ran in to an issue while my corporate policy forced me to assign lock/unlock password! Soon I enable password and lock, phone stops responding!!! I have to either pull the battery or issue reboot command via prompt!!!
I hope this helps.... I am not a developer though....
I have been disappointed by the nexus launcher's performance as well.
The black screen requiring a reboot (or if you hold home and happen to have settings in the app switch menu you can force kill it and restart it) is a common occurrence with seemingly no pattern. Sometimes it after a long browsing session, other times its happens after deleting a single e-mail message and returning to the main screen. The only consistent way to make it happen is to hit back after launching camera from the app drawer.
Ive also noticed in every rom with launcher, that when coming out of the launch screen the app shortcuts and widgets on the home screen don't load instantly. Almost as if the launcher was killed while it was asleep and when unlocking it, it is reloaded.
It's disappointing because as you said, while helixlauncher is an OK alternative, nothing else has quite the same feel as nexus launcher. Unfortunately I think it will take a good bit of modification to make it a perfect match with the hero and I have absolutely 0 idea where to even begin .
Flipz, if you ever read this, could you offer some insight on this? You've worked your magic on the 2.1 lockscreen
The only rom i had it running great on was Darchlegend v4.1 i think it was, i finally said forget it and started using helix
Every one i have tried has been buggy as well. Things mught improve once we get the hero 2.1 source. Or once google decouples them.

home screen lag!

Im gettin quite abit of lag wen scrolling through the pages on the homescreen.. I do have a few widgets but I'm coming from having the htc incredible s which had much more widgets and no lag. Does anyone else have this problem? And is there anything I can do to stop it without removing everything.
Hmmm no lag here, all I can say is try a factory reset then place all the widgets down again and see if that helps.
What homescreen laucher are you using?

I've filled up 4 pages full of widgets/apps and I get no lag whatsoever. Not sure what's happening with yours tbh.
BullSh!T. Theres absolutely no lag with the homescreen. Your lag is called user error
Don't mean to stray off the sub but how is ur battery life considering ur 4 pages full.? Jus mine sucks an I was wondeing if its down to that

When I was playing with my new toy like crazy I was getting a day in a half. I check 10 webpages hourly, tons of emails, text, usually 30mins of calls, start my music thru headphones around 9am till 5pm, checking xda app hourly, and other random things.
Its 8:18pm and im at 37%. Ive downloaded 2 torrents thru wifi, handled business thru google voice(mostly text) since ive been home. My vibrant would usually die around 5pm while at work. Im a extremely heavy user and im getting great battery life.
Ive just checked my phone. 3g/H+ stays on all day, auto sync is off, brightness turned 100%, all emails sync hourly thru samsung email app.
Ur so lucky, I jus can't get to the bottom of it. Did u charge ur battery all da way at the start an do u let it die then recharge it off? Give me some pointers. I'm hoping its jus not a faulty phone. I mite buy a new bat
What is your battery usage like? Get us a screenshot

i too have the lag actually. I find that the enlarged accuweather widget that came with the device to be the main culprit, not sure what else. I've switched to launcherpro for the time being.
I can confirm that the stock accuweather widget makes a little lag. Changed to Beautiful Weather and the lag was gone.
****ty apps and widgets make even the best of the smartphones lag.
I can confirm there is lag too....once in a while. The lag is most easily reproducible if you slowly change from one home-screen to another. Drag your finger slowly rather than do the typical swipe-and-release action.
Sometimes it is noticeable lag, but to me it is more like skipping a frame or two during UI rendering.
i notice this lag too, do anyone else notices it? like elythor stated, you can see it well if you slowly change screens, like it skips a few frames, it is not 100% fluid.
5pages widgets one full screen caledar page. Ob i know this is ovious to some but try extending the refresh hours for your widgets. E.g weather 3 hours. Etc

I had no lag on KE2. I upgraded KE7 on top of it and I started to notice some lag. I formatted my SD card and internal storage and then did a hard reset. The lag went away.
i am on ke7 and i have a lag when i go the the home screen. be it using the home button or just pressing back until i get there.
it goes back to any other screen very smoothly, but when it goes back to the home screen, there is about 3 seconds lag.
i have 5 homescreens, using stock touchwiz
Any of you guys using live wallpapers?Always found them to cause some nasty lag on my phones(Currently Desire HD,maybe GS2 in the near future...Well,that or Sensation! ).If yes,try switching to normal pictures or lighter LWPs.
Now that I mentioned it though,could you guys do me a favour?There are four LWPs on the market from maxelus.net,Shadow Galaxy,Inferno Galaxy,Ice Galaxy and Vortex Galaxy.They are magnificent,but are causing far too much lag on my DHD.Could you guys test them out and tell me the results?
Now that I think of it they suit the phone...A galaxy wallpaper on Galaxy S...
Sorry for offtopic,eh?

I have lag too going to home screen about 3 second, very annoying but it is on ke2, touchwiz, 3 screens, weather and time widgets. Sometimes lag is smaller. Removing all widgets i have small delay about 1 second returning to home screen. I wish it would be instant...
P.S. No live wallpapers

i think its the launcher.
try launcher pro, and the lag will go away
however im staying on touchwiz because i really like the widgets, unless you know any way i can get all my widgets with any other launcher?

Ugh is there something wrong or am i just nitpicky?

When I turn the screen on, sometimes but not all the time, the screen turns on but the text at the bottom where it says swipe to unlock and Verizon wireless is not present and the screen is unresponsive but after a few seconds it appears and I can then unlock my device. I feel like I just keep having issues haha.
Happens on mine as well, but only for a second or so it seems. I tried turning the watercolor effect off to none but it still did it, I think its just the crappy samsung lockscreen wish I could get the stock AOSP one on there.

haha me too man it's probably because i'm so used to my rooted Note 2 where I fixed all these laggy issues. Damn Samsung needs to polish touchwiz badly. Thanks for responding again btw.
Happens to me too! very annoying because i have to swipe to unlock twice
I do use dashclock on my lockscreen
Well I ended up freezing the stock samsung clock with Titanium and taking the stock clock from 4.3 off my Galaxy Nexus and putting it in system/app and changed the permissions to match, its a little smaller I think because of the high resolution but it doesn't seem to lag out like the stock one did better than it was
Touchwiz is composed of lag. Every time I turn on or off my screen I am reminded. It helps if you are constantly using the task manager and clearing ram while closing apps but this should not be a necessity for the OS to run smoothly.
I may just have to become a de-hack-loper to get this unlocked bootloader going however even then knox is watching us.

FYI that clock is chronus in the play store for people that arent rooted
Chronus looks much better perfect size. Now if only I could get the cyanogen lock and shortcuts close enough

Try holding down on the icons and moving them. If you can, remove them from the screen and re add them. If not, try disabling any xposed modules (if you have any that could effect the home screen) and look at it again. I don't personally use the touchwiz launcher and this never happened to me, so these are just guesses. Also, I noticed you have a strange colored Google app in your bottom bar. Did you do anything to the icon, and if so did you possibly break other icons while doing it?

I did factory reset my phone and still see these , is there any software to fix that or this is a hardware issue .
is this called a burn-in issue or it is called some thing else .
thanks for replying .
Are those applications actually there software wise? If not, then it would be a burn-in, where the screen has the images "burned in" and can't be removed. If they are there you could try flashing a stock tar using Odin for whatever build you want.

yes , they are software wise and if you look very good in the pic you can notice the whatsapp shadow on the screen , also I had flashed the stock.tar odin rom many times and they are still there , if this case is a burn-in issue what software would you suggest to fix because I tried all the softwares on the playstore and they didn't help .
thanks

The only other thing I can suggest is to take your phone to Verizon and see what they can do. They might have to replace it.
having same issue in MotoG3
I got this phone(MotoG3) 15 days back, it worked fine for a few days and suddenly I noticed that a "Whats app Shadow" is coming on my home-screen, it was hardly noticeable at first but then it became darker and darker, I replaced the phone thinking it might be a software issue, and got the same handset today itself, it worked fine but again as I installed whats app the same shadow problem appeared, I uninstalled it and it started to work properly. Am not sure where is the problem, so please help me out.
About the shadow issue:
The home screen of whats app appears in my wallpaper and also above all the other apps, a transparent shadow kinda thingy, I hope you people got what am trying to say.
Thank You
I also have the same issue on my redmi note 8 but in my phone i doesn't shows the shadow of the icon but but the shadow off appa inside when I use anh app
I have the same issue on my Pixel; the shadow apps aren't directly on my home screen, but when apps are opened. Perhaps due to Google system.

White overlay on home screen

Edit: figured it out.
I downloaded a bunch of apps last night that required screen overlay (draw over other apps) permission to operate. I uninstalled all of them, but now when I scroll horizontally on my home screen of Nova launcher, this white transparent overlay pops up on my screen except over the status bar. It’s most apparent when reaching the far edges with infinite scroll turned off, where I can hold it in place. I have a screenshot, but I can’t post it yet. It’s on the Lgv20 subreddit though. It also flashes intermittently when I swipe anywhere horizontally. Swiping vertically to open app drawer doesn’t seem to trigger it. It disappears when I’m not touching the screen.
I had Flynx, Amaze browser, Flyperlink, chromer, Link bubble brave (from apks), Trine browser, Hermit, and swipe for facebook downloaded. I’ve since removed them but it’s still there. I’ve tried restarting a few times and ran the smart cleaning. I’ve also tried redownloading the apps, clearing data, force stopping, then uninstalling, but no dice. I’ve gone to the Special access>Draw over other apps section and disabled all third party apps I’ve ever downloaded, and I’ve also restarted Nova a few times. This hasn’t accomplished anything, either.
Other screen overlay apps I have installed include Simple Pie, Status, Directchat Pro, Lastpass, Airdroid, and Screen Filter, but these haven’t caused problems before.
Help on this issue would be greatly appreciated. The flickering is driving me nuts!!

Go into safe mode and see if it still happens. If not, you missed something.

Thanks for the reply. The effect doesn’t occur on LG’s default launchers, even outside of safe mode. Or at least I couldn’t get it to trigger. This is why I suspect this might have something to do with Nova, but I wasn’t sure. I’ll try reinstalling instead of just restarting. I rebooted into safe mode, and the effect wasn’t present, but I couldn’t test Nova.
figured it out. sometime in the process of installing/uninstalling apps and fiddling with the settings of the apps (some of which added icons to the home screen which was locked), some of my nova settings were altered. One setting I saw was that infinity scroll was turned on even though it supposedly isn’t compatible with the nova google now companion. Probably why it was glitching a ton and caused chromer to crash repeatedly when opening links from there (unsure). Some animations were also changed for some reason. I reloaded a nova backup I had and all was well.
