LeEco Le Pro 3-- red screen occur when pressing the power button to turn off.

Hello everyone, I got LeEco Le Pro 3 two weeks ago. For the past two weeks of testing, I notice that the screen quickly turns red when pressing the power button to turn the screen off. Is any of you facing this problem? It happens randomly, not every time. I have attached the video in slow motion capture in the 7z zip file. So you can see, what I am talking about. Let me know if any of you see it.

In mine sometimes it blink red. Power sleeping your phone rapidly. May red screen is reaction for force kill app?

I did not power sleep my phone rapidly. The red screen still persist. I don't know if force kill app cause it. I submit the feedback through the leeco experience center about this issue. This is what I got from them:
"Le Engineer
Hello,
I just get some information for this issue, in low battery level the red screen issue will happen sometimes. We also find the same thing on other brand device.
However R&D team are working on it. Hope it will be fixed in next generation product.
Sorry for inconvenience. Thank you for choosing the LeEco."
So I don't know if my phone is defective or not. It's hard to tell. Base on this message, look like there is no fix for this.

I saw this movie. My phone behave as same as your <sometimes>. May it's EUI problem? Somebody on other ROM like MIUI or CM13 can say something?

Mine occur sometime, too. Here is what I analyze:
1. On the home screen; when pressing power button to turn off, red screen occur sometime.
2. Any app that has white background like the waze app I use in the video, red screen occur every time I turn off the screen while leaving the app running. That goes for other app like chrome, whatsapp, google map, gmail, etc. Same result.
3. On the back button, when I press hold, the screen turns off. No red issue. This was on the home screen and this rarely happen. But for apps that is open, same issue.
That is what I like to know if it is hardware defect or software EUI problem. It looks like software issues. It would be great if someone would test it with different roms such as CM13 or MIUI.

It could be a software issue since I don't have that on CM.

I never seen with MIUI 8, can anyone give me a sequence to try ?
Tried some times, shut down it's too rapid to see with MIUI.

If you have another phone with slow motion support just like I did, you can try that.

Other thing I want to mention, I would like to know that if the red screen does not happen to people who have CM or MIUI on lepro 3, can any of you go back to EUI and try to do the same steps? If you can. This would more confirm that the software is the issue and not the hardware defect.

Any update?

Hi folks! I've been searching for this rare issue since I got my LM2 last week. I have the very same issue and I notice the same @crazy1990 mentioned here. Besides, I notice this red light is more noticeable when the brightness is higher.
IMO, I don't feel it's a matter of bad hardware (I hope so), as there are no clues of any other issues at all. I'm also using stock (23s) and I suspect it's some poorly designed fade for the ROM.
Any updates from anyone?

Yes. Red screen blink is noticeable when the brightness is high. As of June, I still have this issue since November on this stock rom 21s. So far, there was no screen degradation or any kind of lcd problem. Lcd works perfect since day one. A while back, I installed lineageOS and I still experience red screen when the rom froze and reboot. At this point, I still don't know if it is the software or hardware. I hope someone can help us out.

At least your report is positive. :fingers-crossed:
Did you try other custom ROMs? RR, Cuoco?

No, but I already tried omnirom and purity rom. No red screen issue. I also tried tars 21s and turbo base rom, the issue is there.

Great to know it doesn't happen on Omni/Purity. My biggest concern was an increasing degradation and/or flickering issues arising when changing to a stock ROM.
Thanks for your information.

Touch issue

I am not sure if it is touch issue or display issue. https://www.youtube.com/watch?v=JdMbbML9ECg Please have a look at this link.
The touch works for 2 seconds of screen on. Anyone having same issue? Please reply if anyone has fixed this issue.

same problem.
It's like the smartphone, after a 2 second make a check then blocks the touch.
I noticed that if I touch the screen before turning on the smartphone, the touch does not hang after 2 seconds but after more than 2 minutes.
I'm not sure it's a hardware problem; I still believe that it can be solved by preventing the above control.

TouchScreen Issue

Which ROM and Kernel are you using? Should be a kernel related issue, try flashing a different ROM or Kernel.

already tried but not switched kernel,i am running default kernel with jaguar oreo rom

I am also facing the same issue, since i have flashed custom rom [Pixel Experience], initially i was using PixelExp-24/01/2018 i didnt faced any issue i was using for almost 20-25days & recently i have flashed PixelExp-07/02/2018, after 3days the nav bar stopped working intermediately & the touch response only once after screen unlock & not responses until or unless i lock it & unlock it, then suddenly touch starts working but where ever i touch in the screen Google-Assistance opens.

I had the same. I used a piezoelectric of a lighter to give static shocks to the screen while touching it with the other finger. It worked.

I had the same issue, and fixed it by removing the screen protector. Now the touch has been working since yesterday

I am also facing the same problem on my phone.
I tried discharging the phone completely and charging again.
I use the original charger only.
I'm running Pixel Experience ROM on stock kernel. This problem started a week after unlocking and rooting my phone. I also feel that it is not a hardware issue.
The problem started with the nav. buttons: The rest of the screen functioned properly but the nav buttons were unresponsive. A little later (a few hours), the entire screen responded to touch intermittently, and after that it responded only a few seconds after unlocking the phone (the above mentioned problem).
I am having a very tough time as this is my daily driver and I'm stuck.
Please Help. Thanks a lot in advance.

This is exactly what has happened to me too. It started with the nav. buttons and then the rest of the screen. Have you found out what is to be done?

Guyz try a cell ,u know those 1.5 v cells use them as the s pen im not joking it really works u just try once

No solution whatsoever!! I just cannot believe this is a hardware problem. My screen works (most of the time) for 2mins if I wake the screen up while touching it with one of my fingers, otherwise the screen works only for 2 secs.
This problem has been discussed in very few places although there are many people who are affected. Loosing hope.
Can I exchange this phone on Filpkart/Amazon in India?

I exchanged my z2 plus with this problem on Amazon without any problem. They only want a phone which switches on and whose display is not cracked

Exactly how did you did that? Could you explain?

Broke a piezoelectric lighter and got the raw mechanism.
I made it discharge several times on the affected area while touching another area of the screen with another finger

Workaround
I tried one workaround indicated by someone else on another thread. Follow below steps
Press power button to put screen off
Hold phone in left hand and put left thumb on screen
Press power button to start screen
Touch with right hand fingers
It will work till left thumb is there on screen..
If touch is lost follow from step one
Atleast this helps alot instead of only 2-3secs stuff..
Thanks to one who indicated this workaround

Found a solution
Hi I was also facing this problem and I was ready to give up then I tried changing custom ROMs and when I installed the dot os v2.4,the problem disappeared and I was back to using the device normally
Hope this helps

Toch screen issue while typing

I'm using Indian variant (BND-AL 10 8.0.0.320(C675) and I'm really frustrated with this phone. I thought stable oreo would fix this issue, but it didn't. It's really frustrating to type slowly. Seems like there's something wrong with the touch, the response is very slow while typing. This issue occurs when the phone gets slightly heated. I need to press the keyboard slowly to type the letters. Although I do not face any lag while using this device.
I'm using latest oreo update. I even did a factory reset after updating to oreo, still the problem persists.
It's been 4 months since I've been using this phone and it's a total disappointment.
I have already tried factory reset twice after updating the phone to oreo. If there is a workaround for this issue then please let me know
Thank you.

Maybe its another issue. Your out of storage or you have to many apps running in background. You can try to clear data on google keyboard. I have no lag on keyboard on oreo.

I took my phone to service center and they installed fresh Oreo in my phone. Works like charm now. I think fastboot was the solution for this

Mate 20 X Unresponsive Screen

Hello guys!
I have bought a brand new Mate 20 X just 3 days ago!
I noticed that some times I click something and it wont do anything or do it with delay and sometimes I click on something and it vibrates like it did it but nothing happened (like home button for example).
Does anyone else face this issue? do you know how to fix it?
Have a great day!

Nothing here, I also use the gestures so never use the home button. Is it specific apps that cause issues or just in general?

Yep, it happens to me quite frequently. I don't think it has anything to do with the screen though. Do you have a nano memory card? Are you stock? What apps have you installed? What browser do you use? Mine started doing it after the 192 update (I think) and has been doing it ever since whether I'm on stock or on a custom rom. You'll tap a program and see that it selected but sometimes it takes like five to ten seconds to open.

sometimes when I touch with 2 fingers to zoom (for example on a document) it just stays on zoom mode even when I touch with 1 finger (so when I try to move around it will change the size like a 2 fingers gesture).
scrolling is way slower than any other phone I tested, has anyone else noticed that?

Take screen protector off and clean it might be smudged . Maybe you could try glove mode it's more sensitive in settings

tried both, didnt help.

I thought I was the only one with this issue.
After flashing the Resurrection Remix rom I have never encountered this problem.
I'll be going back to stock soon so I'll see if the problem still exists.

Mine works perfectly. Even with the protective film scratched. Worked perfectly with my previous screen protector, a tempered glass type. I have the chinese EVR-TL00 midnight blue model. Everything stock, no root.

I also have this problem
You're not alone, this is happening to me as well on the EVR-L29. In my experience it is most noticeable when tap typing and a letter I tapped on does not register. Also, once in a while when I tap on an app to open it nothing happens and I'll have to tap it again for it to open. It's a mild annoyance for me, but not to the point of ruining the experience. I'm hoping a future software update addresses this, unless it's hardware related. I love the phone, but this is probably my biggest gripe outside of the possibility of no future upgrades in Huawei's spat with the US.

Lock Screen unlocking problem guys, screen is unresponsive for 3 seconds.

after each lock when i turn the screen on with double tap or power button screen is unresponsive for good 3 seconds. This started happening after the latest camera fix update. When if i use aod and use the fingerprint through the aod this doesnt happen. tried reboot and factory reset with fresh install (no backups) tried safe mode. Same thing happens.
S20 plus exynos.

Yup happening to me too (s20+ exynos). For me the time of unresponsiveness is around 1-2 seconds. Happened after the latest update.

Yes, have been facing the same issue since "ATCH" update.

Yeah has been driving me nuts. Same problem.

I'm surprised this isn't gaining more traction? Can't be the only few experiencing this!?

Glad to see it's not only my device. Waiting for fix.

I have similar situation

I'ne noticed the same after the last update.

Seems like a pertaining issue for Note 10 Users too. They found a trick and seems it works better now. Can you try this and let me know if it works better?
turn off the battery optimized for apps: com.samsung.android.biometric.
Go to Settings>Apps>Select "Special Access" from three dot menu>Optimise Battery Usage>select All from drop down menu>Search for "com.samsung.android.biometric"> Turn it off and Restart.

For a moment it felt like the issue is resolved!
But after checking several times I can confirm the issue still exists.

I did this already and while it feels like fingerprint is faster, unfortunately this is a screen issue. You see if the screen is off and i put the finger in the correct spot it always scans my finger without any lag. The issue is occurs when -
a) I have unlocked the phone using above way, then the screen becomes unresponsive right after unlocking.
b) The screen is off and i either press the power button or double tap to wake, then the screen will be unresponsive and its during this time the fingerprint scanner doesn't scan (because the scanner doesn't know it needs to scan since the touch is unresponsive)
so TL;DR its not a FP scanner issue.

I am quiet sure Samsung is already addressing this issue for next update.
