2nd Screen not showing with main off but shortcuts still active

[aim1999x]

Just got the phone ,stock att, I already did factory reset it doesn't show 2nd screen when main off but the shortcuts still work(flashlight camera etc..). Could it be that it is super dim, anyway to change that ? It works normal with main screen on. I am on latest att update. I looked everywhere and didn't see anyone with similar issue that didn't get fixed by factory reset. Phone is unlocked also. Any ideas ?

Could you give a little more information about your problem?
The phone has a sensor that detects when you have a flip cover on and shuts off the second screen until you open it, so it could be there's something in front of it.

Another thing you can try is disabling Quick Cover in the settings if you don't have the official LG cover.

I tested that sensor with aida64 it seems to be working fine when I put my hand in front of it, also it doesn't show anything in front of it otherwise. I disabled the quick cover option and enabled it doesn't work either way. One thing I noticed that if I use quick cover case and open and close really fast I can see the 2nd screen being on for split second and then it goes black even though the shortcuts are still there.

Ok. One last thing you should try is to go into settings, Second Screen, and toggle the two options in there. One should be for when the main screen is on, another for when it is off. Switch both of them off, then on, and restart the phone. If that doesn't work, perhaps there's something wrong with the screen.

Yeah did that, no difference.

Could you post an example of what exactly is happening? The second screen does have some issues, mainly light bleed, but that's something that is inevitable due to the manufacturing process. It could be a problem with the backlight, because as far as I know, the screens are independent and don't utilize the same backlight.

I see now. Does the signature show up or do neither of the options work?

I am not sure, but you could also try manually setting your clock and weather settings as well. It is definitely something software side.

Neither option work. Though like I said even though screen is dark if I swipe it to the left with main screen off the shortcuts do work. I want to think this is software issue, but then factory reset should have fixed it. With smart cover it will stay on for half a second and then go dark.

Believe me, factory resetting a phone can fix many issues, but if 8ts a bug in the ROM itself, it won't fix that. It is a very strange issue, I admit. I don't know if the phone has a separate backlight for ambient display, but if the screen works when the device is unlocked, it should work when it is off.

My best recommendation for you is to exchange the phone if still under warranty. If you cannot do that, then perhaps try flashing another stock AT&T Rom. If you are unable to do that, then your best bet is to keep fiddling with settings to see if it gets fixed or not.

I did buy it on swappa. I do have the receipt from the person that bought it at att store (it was bought in december last year) however I am on cricket. I doubt att will help me. I may need to send it to LG as last resort. I was just hoping there is something else I can do. Could you point to a good guide regarding flashing a stock rom ? I haven't flashed anything in a while

I used this guide a quite some time ago when I was removing a rooted FW. I hope this can help.

I sent the phone to LG and they "repaired" it. They friggin replaced the lcd and obviously didn't test for the issue. It is still there. Question is should I return it again or should I try flashing it myself ?

Well, I flashed latest stock firmware using LGUP refurbish option and it didn't fix it. Does anyone have any other ideas ?

Well, I can tell you from experience that whomever received your device for repair probably didn't get all the information. He or she was probably told that there were issues with the screen and to just replace it, without anything else. This is what happens when you have a third party that doesn't understand much about the technology or the devices themselves transferring information between two points.

I can honestly tell you that if swapping out the display didn't fix your issue, there's not much to do about it. It's a shame though, because this is a great phone, and besides battery life, LG nailed pretty much every aspect of what a great phone is. I think your best best is to contact the original owner and notify them of the issue and work something out. Other than that, you can either keep using the device like it or switch to another phone.
