You guys can enable immersive status bar to prevent burn in. Autohides status bar and when it does appear it's a transparent black so that's pretty neat.

Open adb type, adb shell, once you see your device your ready to write commands. Here they are

HIDE STATUS BAR: adb shell settings put global policy_control immersive.status=*

HIDE NAVIGATION BAR: adb shell settings put global policy_control immersive.navigation=*

HIDE BOTH BARS*adb shell settings put global policy_control immersive.full=*

RESET TO NORMAL: adb shell settings put global policy_control null*
[Samsung Galaxy S8 Guides, News, & Discussion] dmartinez21:
Thanks, Just ended up using this method to hide both bars and I actually prefer the look and feel of it!
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
I thought it was pretty neat also. its working pretty good but a few bugs, in Samsung browser it won't show recent open tabs for some reason. Also when trying to exit the keyboard in messaging if you swipe up for the navbar to display it brings up the keyboard. I also wish I could have the navbar stay on the screen a little longer, its set to auto hide at 2.0 seconds, I would like it to be around 5.0 seconds. I'm looking for adb command for this but I'm having troubles finding the correct command path for setting this, any help with this will be greatly appreciated.

I have Note 3 since release, I'm not even sure fall 2013 or 2014? Using it daily all this time except maybe for a couple months misadventure with N7 and there is absolutely no burn in whatsoever. And that phone has fixed home screen, with same 4 icons on the bottom since original setup back when I bought it. It is on a second battery, which was breeze to replace, which will not be a case with S8. Anyhow, there is absolutely no burn in on my 10 day old S8 and I don't think there will be and even if does, I don't care, it's the part of the screen that's rarely used for anything else but navbar. Rest of the screen is never static, so that should not be a problem. My much bigger worry is: will the battery last and not to drop it and break the darn screen, I did that with N7 despite having a case.
[Samsung Galaxy S8 Guides, News, & Discussion] peachpuff:
If the nav buttons are burning in the shouldn't the status bar icons also burn in?
[Samsung Galaxy S8 Guides, News, & Discussion] abdullaha:
I'm not seeing any burn in. Which is interesting. Has everyone disabled the always on screen's home button square which always stays on and can burn in?

I have it disabled and I don't see burn in. Ive had it since launch day

Worth a try if you havr burn in. It's usually reversible if it's not to bad.
[Samsung Galaxy S8 Guides, News, & Discussion] Enzo1707:
Hi everyone,

I would like to know if you have the same "problem ". I've received a galaxy s8 last Friday. Everything was great except one. I've a noticed a potential image retention. For example, the (black) navbar remained on the screen for 3-5 second after closing an app. Or the black bar on the top (when apps aren't full screen) was noticeable also after closing. So I went to a store to see their galaxy s8 and s8+ and test it. The results was clear, their galaxy s8 had the same "problem" but not the s8+. So I decided to change my phone and get a new. Surprise, same thing... then I went to another store and their s8 also had this potential issue but not their s8+. So I've seen 4 galaxy s8 having this problem. My question is simple. Am I the only one ? Will it get worse ? Is it normal ? I don't think that my store is going to change my phone again. Keep in mind that this "image retention" is more noticeable on a blue or gray picture. Thanks for your answers.
[Samsung Galaxy S8 Guides, News, & Discussion] Benjamin Dreyer:
Actually, I just realised that burn in image should be darker, not lighter. So, I guess it's not a burn in - that's a problem which happens when you're using Navbar Apps with constantly black navbar. Because I look at my home button burn in and it's the same colour that the test of the screen. So, looks like the screen itself "aged" a bit, except navbar. I disabled navbar apps to see if this problem will go away in a couple days.
[Samsung Galaxy S8 Guides, News, & Discussion] MyanRagahis:
I figured I'd post a photo of mine just cause. It's not awful but it's there. Most of you will barely notice it probably.

[Samsung Galaxy S8 Guides, News, & Discussion] philipone69:
I got as pissed and scared as you when i saw this burn in thing BUT i don't think this is permanent burn in. Here's why. I donwloaded a pure white jpeg with a black stripe in the middle, made it full screen and hit the brightness at 100% for 30 seconds. Than i checked again the grey jpeg at 100% brightness and there it was, a clear shaddow of the black stripe from the previous photo witch slowly went away in 15-20 secs.... BUT no burn in whatsoever. I think it's just some image retention and seems temporary. Leave the grey photo on display for more than 30secs and the nav bar will blend and the shaddow will dissapear. I wouldn't worry too much. Tested the old s7edge the same way and it does the same thing. I think this screen has the same quality if not better than the old one.

Just checked my s8 and I see the home key button burn on mine
[Samsung Galaxy S8 Guides, News, & Discussion] h4ck3r69:

[Samsung Galaxy S8 Guides, News, & Discussion] JaeMelo:
lol if this is fixable then /thread
[Samsung Galaxy S8 Guides, News, & Discussion] VonSohn:
Maybe it's a case of image retention, as philipone69 experienced. You should all try what he did, and see if it's permanent or not.

I'm receiving my S8 in a couple of days, and hope this is not an issue. Will report!
[Samsung Galaxy S8 Guides, News, & Discussion] Joescalon:
No issues here and I used a fixed image with navbar app. I think this is the reason for the white navbar when using keyboard. Really think this should auto hide keys like LG does.
[Samsung Galaxy S8 Guides, News, & Discussion] Hazzo31:
I am no expert but I once read that it's not burn in but that the screen in the black portions it's less consumed.

Let me explain.

Theoretically in AMOLEDs (OLEDs) the pixel is the led. When the pixel it's turn on it has a color, when not it's black. So like all my Nexus with AMOLED (Nexus 6 & 6p) if the navbar is always black (or most time), sooner or later you will see a bar at the bottom of your screen that it's "brighter" than the rest of the screen because it has been more time turned off than other pixels. Also the buttons in the navbar may look burned in but really they are contrasting with the intensity of the screen where the navbar pixels have been turned off. Following this theory the white buttons pixels remain turned on in a specific color wich with time get washed away because the lack of brightness (they are more "consumed").

This is just a theory that I once read and sustains that not matter what, if you have an AMOLED screen with navigation buttons you will for sure get this effect. It doesn't matter if you don't see it, it will happen. For example on the pixel c that has navigation buttons this won't happen because has an LTPS IPS LCD panel. A burn in (no powerless pixels XD) could happen but it would need hours of turn on static screen.

Hope this helps. If this it's just ridiculous I can guarantee for sure that in all my AMOLED screens I got this "burn in" :D
[Samsung Galaxy S8 Guides, News, & Discussion] gabrielgon:
I`m still waiting for mine to arrive but I`m getting worried about this. Hiding the top bar is great, I even prefer it this way, but to keep swiping to show the bottom bar is a great hassle for me.

I think it would be optimal to leave bottom buttons working but invisible, if you know what I mean. That way we wouldn`t need to swipe and there would be no burn in.

Would this be possible?
[Samsung Galaxy S8 Guides, News, & Discussion] TehPirate_:
check out All in one gestures. It's what I use and never need to use the navbar.
[Samsung Galaxy S8 Guides, News, & Discussion] M5Rahul:
I've always done this with my previous Galaxy devices ( play store app : Galaxy Button Lights) up until the Note 7. But, the app doesn't work on the S8.
[Samsung Galaxy S8 Guides, News, & Discussion] gabrielgon:
Those gestures might interfere with some apps` interfaces, like swiping from the side. Clicking the status bar isn`t an option as I`m hiding it. I`ll keep looking for a solution, but thanks anyway :)
[Samsung Galaxy S8 Guides, News, & Discussion] Enzo1707:
Does all in one gesture drain a lot of battery ? I'm maybe going to use it.
[Samsung Galaxy S8 Guides, News, & Discussion] TehPirate_:
Not that I've noticed. I get well over a days usage with minimal usage such as texting and calling. 2 days on battery with 40% remaining. Best is to try it and see how it is for you, your experience may vary.
[Samsung Galaxy S8 Guides, News, & Discussion] cheetablaze:
Very interesting, I did the same thing and I could see the bottom clearly burned in. However I gave it a minute and it disappeared.... So yeah maybe it could be permanent down the road?
[Samsung Galaxy S8 Guides, News, & Discussion] Skander1998:
Load a white picture and set the brightness to 100% for about 30 seconds (make sure it covers the whole screen).

Then check.

For some reason that I do not understand, there seems to be image retention that looks like burn in but isn't. This shouldn't be the case on AMOLED but I'm not complaining xD
[Samsung Galaxy S8 Guides, News, & Discussion] INGHUGO:
I just downloaded an application that hides the bars the name is GMD immersive you can download it from playstore i recommend the pro version

[Samsung Galaxy S8 Guides, News, & Discussion] tasked28m:
Same. You wanna get really pissed of? Get 2 grey pictures(one light grey and one dark grey) and open them with gallery. Zoom untill it fills the screen and woila. You have burn in all over the place. Its not image retention . Its what samsung was kind enough to warn us about LG OLED Tvs that are prone to brun ins thus they choose Quantum Dot over OLED. Am guessing they missed the part that there mobile phones are OLED.
[Samsung Galaxy S8 Guides, News, & Discussion] gc180:
Got my S8 since June 7th 2017, no burn in whatsoever. Even when viewing grey image. I don't hide the status bar or nav bar at all. Brightness around 40% during the day and about 20% at night. That's comfortable for my eyes but I do increase it if needed.
[Samsung Galaxy S8 Guides, News, & Discussion] domsch1988:
Yes on a grey background I can see some burn in. Even the pixel overlay is already burned in after two weeks of use.

Doesn't bother me though. Since I keep my navbar on 98% of the time I won't see it anyways. The only full screen apps I use are video and you can't see it over a moving image.

I have the j3 emerge 327p, rooted and twrp installed (thanks to Ashyx for building twrp and making a way to decrypt data partition!!)

Ok seeing as no-one could be bothered to respond to my post I'm just gonna leave this here.

It may boot it may not? It may not even install if this device has a locked bootloader.

If it does then great, report any issues along with the recovery log.

If it doesn't then descriptive information is required along with screenshots where possible. Anybody who simply posts generic 'NOT WORKING' will be ignored.

bootloop

It flashed just fine, but will not boot. The partitions seem to be off as you can not access microsd, or internal storage and wipe gets permission denied errors for usb otg and microsd. Thanks for working on this...I tried porting it but it didn't even flash:crying:
[Samsung Galaxy J7 Questions & Answers] ashyx:
You say it doesn't boot, but it clearly has, confused? :confused:

Also the errors I'm seeing is what I expected using the stock kernel.

The internal storage won't mount until the /data partition is FORMATTED to remove encryption.

Thanks for testing and reporting.

Do you have a updated root zip or does the AQB9 root zip from your thread still work?

Both stuck at splash screen, even after updating to newest
[Samsung Galaxy J7 Questions & Answers] ashyx:
I will update the new boot images, but can you try it with the AQB9 and see if it boots then try booting into recovery again?
[Samsung Galaxy J7 Questions & Answers] ashyx:
Seems there's some secret sauce to get TWRP to boot on this device. As posted previously by RS.8253 we have actually had TWRP fully boot and working after some jiggery pokery with the boot image.

With this in mind I've compiled twrp and the stock boot in one package. It likely won't boot to system, but follow the steps below to see if TWRP will boot.

1. Ensure OEM UNLOCK is enabled in developer settings to disable FRP.

2. To remove encryption boot to stock recovery and wipe/factory reset the device. Please note this will completly wipe the internal storage, so please make sure you have everything backed up that you need.

Immediately reboot to DOWNLOAD mode from recovery.

3. flash with ODIN the file below ensuring auto reboot is disabled.

https://www.androidfilehost.com/?fid=961840155545594807

4. Manually reboot to recovery immediately after ODIN gives PASS. Don't allow the device to boot to system.

5. Wait a few minutes to see if TWRP boots.

[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
I'll try it out when I get a chance, hopefully tonight after work or tommorow morning.
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Negative, using the older AQB9 firmware, followed these steps after a fresh install of the firmware and root, no go. Stuck at splash screen when tring to get into recovery, and also stuck at splash screen when trying to boot normally afterwards.

I'm gonna flash back the AQB9 an go to stock before work, if you could hook me up with a root file for the newer firmware for now I'd appreciate it :D
[Samsung Galaxy J7 Questions & Answers] ashyx:
The above procedure was actually intended to be carried out on the completely stock AQF5 firmware.

I will get around to rooting the new boot image, but if you could try it with the new firmware before rooting.
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Oh lol, ok well I'll probably have to wait till tonight to do that, need the phone in case I get called into work. I'm in FL, hurricane just hit us lol
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Okay just finished doing this from a fresh install of the newer firmware, and the result is the same. Stuck on the splash screen saying Recovery Booting Set warrenty bit: recovery.

I followed the steps to a t.

EDIT:

However, on the other hand it looks like the old root file still works to root the newer firmware...
[Samsung Galaxy J7 Questions & Answers] ashyx:
OK when you've got your device rooted again on the new firmware let me know.

We'll pull the kernel log and see if it gives any clues.
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Ive got it like that now, however never pulled a kernel log, I'll try to look up instructions

EDIT: Is this what you need?
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Ok I grabbed both of these, not sure if this is what you need exactly, but this is on newest firmware rooted and set up. I wasnt sure if you need these files after trying to flash the twrp or before though, just let me know if I did it wrong.
[Samsung Galaxy J7 Questions & Answers] ashyx:
Last_kmsg is what I need, one booted to stock recovery and then another after attempting to boot to twrp.

I can then compare and see if anything obvious shows up.
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Ok got it, I'll get going on that tonight
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Okay so for the one booted into recovery I tried to grab it with adb while in stock recovery but cant connect, I can see it in the View Recovery Logs selection, but I don't know how to get it while booted in recovery... do I boot back into the system then grab it?

For the one after twrp, as soon as I flash that twrp file I cant boot into recovery nor can I boot to system, only download mode, so again I dont know how to get the log from that
[Samsung Galaxy J7 Questions & Answers] hapz:
Why Root?
[Samsung Galaxy J7 Questions & Answers] ashyx:
You don't need to grab it from recovery.

It is saved when you boot to the OS.

You should be able to find it at /proc/last_kmsg using a root file manager.

Or you can grab it via adb shell or terminal.

su

cat /proc/last_kmsg > /sdcard/last_kmsg.txt

You must grab it straight after booting to recovery.
[Samsung Galaxy J7 Questions & Answers] TeknoGodz:
Okay, well here it is from the stock firmware, rooted.

I still don't know how to get you the twrp one, because when I flash that file I cannot boot, not into system or recovery.
[Samsung Galaxy J7 Questions & Answers] ashyx:
It seems you're flashing the combined boot and recovery package.

You only need to flash twrp then force reboot.

Use the one below:

Hey can you throw me a odin flashable stock recovery so I don't have to completely reflash stock again? I've done it so many times now LMAO
[Samsung Galaxy J7 Questions & Answers] ashyx:
No need, just install Flashfire then open the stock firmware with FLASHFIRE and select to just install the recovery.

I'll take a look at these when I can. Can't do it tonight.

Oh yea true, didnt think of that! Thanks!
