Second screen actually on and working but showing only black - LG V20 Questions & Answers

Hi there.
Overnight my Second Screen stopped working. I can see it's clearly on but nothing is shown. If I go back to LG launcher I can drag the icons on it, and I can see icons on it. I've also tried to create a new phone account, and second screen actually works fine. I am rooted. How can I actually fix this? Is there something going on with the Signboard provider? I've also noticed that there are a LOT of wakelocks "EventWindowWakeLock" requested by com.lge.signboard since this happened.

Cursed battery icon

Hello *@*,
I think the battery icon in the taskbar of my Touch HD is possessed by a demon or something. :-|
It is spontaneously disappearing every now and then - pressing the home button always brings it back at once, though. Also doing anything else that updates the taskbar brings it back to life. The disappearance seems completely random.
I can even switch off the battery icon completely with Schaps Advanced Config and display the clock instead. Which is disappearing just the same way. All other icons are behaving normally.
And before anyone suggests a hard reset - guess what happend right after the hard reset I did today, when the HTC booted up for the first time and before I did anything a all?
Right.
Any ideas?

Hmm, can you take your phone to a church and see if it acts up there?
J/K, well my battery icon only shows in the home screen. In other screens, it is replaced with by the little clock. I think that is normal. But it sounds like your battery icon disappears even in the home screen?
Do you (or did you) have anything installed that changes the icons? If you installed the green battery icon cab, did you install the certificate included in that zip file before installing the battery icon cab?
It's weird, that even after a hard reset it would still do it.

At this point, I am considering a bath in holy water.
The vanishing takes part on the homescreen, or rather all the touchflow screens. Installing different battery icons does not help. ArielBattery works, though. It seems to me as if the process responsible for drawing the taskbar icons is "forgetting" to update just the battery icon sometimes. I am quite sure this didn't happen when the phone was new - but a hard reset didn't help.
I had the same problem (I have color top bar icons and green battery icon), but a soft reset fixed it.
You can try uninstalling anything related to that.
Then Soft-reset.
After that, try installing the cabs I installed.
Soft-reset again and see if that works.
Note: Before installing the battery icon tab, make sure you install the sdkcertificate cab included or else you'll have problems with it.
I found all these cabs here in the forum, but I'll post them here for you in case you want to try. You can try just the battery cab (but first sdkcert cab) or also that try the color top bar cab to change the other icons as well.
use magicbutton, its freeware - its a great task switcher and has an optional great power indicator, which is a simple 1 pixel line across the top of the screen... so when its fully charged, you see a white line across the whole screen at the top. If its running low, its not as long and shrinks towards the left hand edge by the start menu.
Much easier to see at a glance than the power icon which appears and reappears at will sometimes!
mine does this i tihnk it is normal but i dont get a little clock it just disappears and nothing replaces it?
pls !! the warrantty will not cover any kind of water contact.. even holy !

[Q] Broken icon background transparency (4.2.2)

I have this issue for a long time by now. I thought it is just the Play Store but no, I noticed it in the facebook messenger too.
Icons and smileys has black background, and in messenger when I use the bubble head thingy, smiley's background is transparent, you can actually see the things behind it, like my home screen wallpaper.
I googled it, but no fix for it, even updated the Play Store. Factory reset did not help. I even replaced the ROM with a new one, but this problem appeared again. (4.2.2, root) I had this problem before the root acces too. I really don't know what to do.
And other forum peeps said the bug only appears on Mediatek devices...
Notice the icons in the Store, and in the Messenger (black background and home screen)
It happens to me too. Its used too be soooo annoying, but I just got used to it. But I still want a fix.
It happens on my phone too and I have no idea why or how to solve it.
I have a Mediatek based phone.

[Q] home screen icon pictures keeps disapearning

Lately, I have some of the icons vanishing like contacts, phone, facebook etc. if I restart the phone they come back but obviously that is not a solution. Also, when i turn my phone on in the morning and unlock the screen real quick when screen comes on, gives me a touchwiz home has stopped alert. but if I wait a minute to unlock, it does not happen. Also, recently, I can not access my multi window pop up view by swiping down from the top corners either?? Any idea what is going on with the random apps icons vanishing randomly(not all the time). appreciate if anyone can help. Thanks.

[Question] graphical glitch? galaxy s5 verizon 900v

Hi- this screen never appeared before and now it does -.- tried wiping factory resetting and this image wont go away from my homescreen. Idk what happened please help looked everywhere of how to remove this but no one has had this issue. This never appeared on stock until after i unlocked my bootloader and installed cm. Tried to use the repair assistant and its still there.
edit: idk why it does not show in my screenshots. here are some photos taken from my iphone... hard to show but there is a white line that is in the background of my homescreen. Shows an sms icon slightly transparent. Annoying **** to look at when I take pics on snapchat. As you can in google playstore and the snapchat photo a SMS icon appears behind the mic in play store and under the switch to facecam icon in snapchat. Does anyone know a fix??
I still have no idea what you are talking about.

lol. ok before on my screen it will be normal fine no graphical errors no visual glitches. pictures wont show it for some reason but if you had my phone in my hand it would show up as SMS icon at the top of my screen like right below the navi bar. Shows up in camera and on my snapchat. Never happened till now. Idk if my screen got messed up or if its the constant switching of roms etc that gave me that glitch. its like a white line that separates the navibar and the rest of the screen at the bottom shows a menu bar on the left corner and some icons. its very transparent under the homescreen display like if the stock rom overlapped
like it shows a small phone screen is under the home screen. in the background- get me?
It's screen burn in. It happens with amoled screens if they are left on a static image too long. You can try some burn in fix tools in the play store. That's why you don't see it in your screen shots it's a hardware problem.

Apps not displayed properly even if full screen is on or off

This is very very frustrating. The apps page shows apps that would work correctly in full screen, as well as those that don't. I have not changed the system settings. However, let's say on an app like snapchat, i don't see a full screen. Along the bottom of the page are the snap camera circle and news button. Even when I'm reading the news. I can't scroll completely down because of this. I have uninstalled and reinstalled the app and the problem is solved for about 5 minutes before it goes back. I've also looked for a setting on snapchat that would change this and there isn't one. Please help!
Maybe some apps Don't support full screen
