Since I have only had my Mi 9 for less than a month, it should be impossible that it already has a Burn In...
However on the part of the screen where the fingerprint sensor sits, I noticed a grey-ish circle, which is exactly the size of the fingerprint. Since Burn In after 2 weeks should be impossible I turned the phone off and restarted it after a Minute and the spot was gone.
Now 2 hours later it is there again.
I don't even use the fingerprint sensor very often, only if I can't use face unlock...
Did anyone experience a similar problem?
(Btw, it's not software, I took a screenshot and it wasn't there)

Well, that's interesting... Do follow this up to let us know what's up.
Before I got my Mi 9 yesterday, I clocked a full 4 years on my Note 4, and never experienced burn in... In fact, I would argue that the display looks the same today, as it looked the day I bought it. (no noticeable brightness drop)
i have experienced this on every "in display fingerprint" phone i've owned, and all it it is the optical sensor slightly visible with the screen off .

Hey Man sorry for telling you so but this gray spot is the actual hole that your phone needs for the indisplay fingerprint scanner to work. You cannot notice it in all conditions. To test it go out in the sun max out the brightness and use a completely white photo.
P.s. there is another hole near your notch which is your proximity sensor

I just got the phone last week and it’s always had a screen protector on it. I know many have issues with the proximity sensor covered but I don’t get how the phone should work. All my other phones turn off the display as you put the phone to your ear and on again if you move it away to look at something or end the call. The Nexus 6 just stays on until the screen time out and then I have to tap the power button to get the screen back.
I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it. It shows 5.000305cm until my hand gets within two inches or so and it jumps to 0. The app says some sensors are discrete so seems ok and the readings are very consistent and fast. So why is the screen not turning off?
Also, the Ambient display setting says it will turn on the display when you pick up the phone or get notifications. Never worked. ???
Bad phone, software or setting?
Thanks.
P.S. Why in God’s name are the volume buttons and to a lesser extent, the power button, dead center of the phone? I hit them every flipping time I pick it up. Is there a way to disable the volume buttons when the screen is off?

my suggestion would be to take your screen protector off. when you pull away from thd phone, the screen should pop on, but it not doung that for you. over the past 8 months or so, ive been reading about this same issue. and its always fixed by raking off the screen protector. im fuessing that your screen protector is covering one of your sensors.
Understood but:

Can someone without a screen protector on chime in with naked sensor readings?

your phone has its own proximity sensor thats being blocked by your screen protector, probably. im telling you that of the very many that have been reporting thus issue, have no more issue when they remove the screen protector. its worth a try, isnt it?

Yea, but the protector would not be usable afterwards and it was really hard to get it on clean and lined up and the sensor readings are the same. I thought the folks that had problems had stuck or sporadic readings.

Mine can be toggled on and off with the power button, never gets stuck. It just acts like the proximity sensor mode during a call never activates. It only powers off after the normal screen timeout if you are still on the phone. The sensor does see me and sets the value the zero.

It’s on, even tried toggling it.
The buttons should be higher. I understand you can’t reach the power button on larger phones if on top of the phone but putting the volume at the center of gravity is crazy. It’s actually noticeably difficult to hold the phone without it dipping when grabbing it lower and that’s after training myself to grab it lower. I still forget and grab it in the middle like any brick sized object. I'm old, hands weak.
I have read here, somewhere, that the proximity sensor does not have a variable output. It's either off or on, so to speak.

Probably yes but everyone who had a screen protector without a sensor cut out had to change it for one with a sensor cut out.
This is step 1. Even if this isn't the cause, it will cause problems later.
You say not variable. Sure on or off. That said, a protector can limit how close the "close" reference can be identified at.
Step 2 is a factory reset.
Unfortunately, can't troubleshooting without doing these steps.

That is my understanding also and someone posted above that they have the same readings from the sensor without a screen protector. They did not say but I’m assuming their phone works as it should when on a call. Again: "I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it.

I know, I know. I’ve read that many have had issues with screen protectors but I thought the folks that checked saw that the proximity sensor readings were also bad. Mine seem to be just what the phone would want to see.
I will take it off at some point and I guess I’ll be the first to verify that even if you use an app to monitor the proximity sensor readings and they look normal the protector can still cause an issue or it is something else.
I did find that the Ambient display will not work without screen lock turned on.

True, because it needs a lock screen to display it.
The screen worked as it should randomly the other day. Only on the one call. I pulled the phone away to look at something and it turned the screen on. Put it to my ear and what do you know, it turned the screen off. Not worked again so far and I ran the sensor app right after the call and it showed just what it always has, zero. Anything close to the phone you get a zero every time, right away. The phone app just ignores the zero reading.
I am thinking about buying a Nokia 7 Plus but one thing is really bugging me.
I am currently using the OnePlus 2 which has a Notification LED and I have gotten quite used to it and I'm not very happy to give it up. The Ambient Screen might be an alternative for me but one thing about it is bugging me. It takes advantage of the face that OLED screen don't use any power to display black. But the 7 Plus uses an LCD.
So how much of a battery issue is using the Ambient Screen with this phone?
the Nokia 7 Plus does not have a always on display. the screen lights up if you get a message or pick up your phone
Yes like what they guy above said and the battery usage is minimal at best
You will get used to live without that led. It took couple days to get used just take phone to hand and it'll show you your notifications.

I agree. I do not miss led notification that much either. I used to have Huawei P10 before with a tiny led which was in fact unusable in daylight anyway, therefore I find picking up this Nokia phone to hand shortly more than I liked the crappy led on P10.
Is it any specific movement of the phone that will make the screen come on? Does it happen when walking for instance with the phone in your pocket?
yes, the phone needs to lay down on a table frist and you need to lift it up. The screen lights up then.
I doubt this happens when the phone is in your pocket.

if you walking without somersault then ambiend is not activated
is need specific movement, from desk pick up to face, or from pocket to hand, in fact needed moving about 90 degress
The phone uses the proximity sensor with the ambient display, so if phone is in pocket, then it won't be activated unless you pull it out of your pocket, and it doesn't need any specific movement, any movement will trigger it on

but this is not true, if you take out phone from pocket/case with movement only in one axis, then ambient is not activated...
Does it have the feature like the moto display, where you can wave above the screen to make ambient display light up and show notifications without touching the screen?
No it doesn't unfortunately – and this feature was borrowed from Nokia on the glance screen introduced in the WP8 era. I was too looking for a comeback on my Nokia 7 Plus.
On a side note – any possible hack to have this ambient display always on? My Lumia 1020 has an LCD screen and has glance screen that can be configured to be always on, so it's not technically impossible. It just consumes more battery, but I like to see the notification status and the clock at a glance without having to touch or hover anything.

Is it possible to remove fingerprint from aod on p30 pro without removing fingerprint sign in? I can't find settings for it...
I don't know about yours, but mine isn't there until I pick up the phone or touch the screen?
If you want to completely remove it then you can't - the way the finger print sensor works requires the screen to light up at max brightness under your finger so it can capture the fingerprint with the optical sensor.
Watch the 'JerryRigEverything' YouTube teardown to find out more info on how it works, but when scanning for a fingerprint it needs the illumination

I was wondering this too as I'm starting to get slight screen burn from a combination of that and the intense light required to unlock. My S10+ has an option to turn it off, and muscle memory dictates that it isn't really necessary after a few days of use.

As I said above, the reason for the intense light is that it uses and optical sensor rather than an ultrasonic sensor (as used in the S10+). Without the light it simply will not be able to see fingerprints.

I understand that but I'd like to at least be able to turn off the fingerprint indicator. I hold my phone in my hand most of the day so it's a bit annoying that it pops up every time you move the phone. You can switch off this indicator on the S10 and it has nothing to do with the technology - it's just a guide.
My Mi 9 display is starting to burn in the fingerprint image after just 2 months of usage. I'm going to turn off the fingerprint unlock to prevent it getting worse.
Does this sound normal?
Doesn't sound normal but AMOLED displays are know for burn in marks. For that to happen you need to have the fingerprint image always on display. I got a MI9 and the finger print image dissapear after some time and reappear if I lift the phone so its almost impossible in a normal usage to burn in the display.
What kind of burn-in is it? Is it the icon, or is it from the strong light that lights up the fingerprint at scanning? The fingerprint icon must show at the same place all the time unlike the rest of the AOD. I can se how keeeping the icon on at the exact same place all the time 24/7 may hurt an AMOLED display. I turned off, both AOD and fingerprint icon, after a day or so to save battery. Now it shows only on the lockscreen for a few seconds.

So I had seen it as a sort of retention of the fingerprint image that appears on the lockscreen. I saw it when I was walking outside in full sun today. I quickly installed an app to check different colours full screen (dead pixel fix) and it clearly showed the burn in for several colours.
But now that I'm home, I tried again the screen check app and the burn in is gone!
So I wonder if it was either just temporary retention, or if I need to be outside in full sun to see the burn.

Please come back here and tell us if you see it again. It would be good to know if the display is this sensitive to permanent burn-in. Keeping the icon shut off at the AOD would probably be a good idea, I find it rather easy to hit the right spot after some time of practice in the blind.
That what you have seen on sun isnt burn in, that is normal see-through screen becase sensor is under display.
No need to panic, i seen it too but that is not a problem.
Same as marko378, it's totally normal to see this on bright daylight, it's not a bur in.
Its the finger print sensor and i see it at day one
No problem bro enjoy your phone

Nice, today in full sun I confirmed what you're all saying. It's the sensor, the hole behind the screen, and it's only visible at certain angles in full sun.
Thanks to you all for helping
That's normal because the scanner is under the screen so it has to be a little transoarent there to work that's why In screen scanners are mainly used by oled displays. Enjoy the phone

It is not safe for the screen in my opinion to maintain the figerprint area always lighted. I use it as per default setting that dimly lights it when I take the phone and then in few seconds it disappeared even if I touch the screen. More than 1 year with the phone and no burning in the screen.
I feel there is no proximity sensor in this phone..
Becuase while i am on call , even though the screen is touched to my ear , it will light up randomly as i am walking and turning.
Is that function managed by accelerometer and gyroscope as in new redmi phones ?
The autobrightness is also acting weird for me in some cases .

It doesn't do so for me but yes if I move my face when talking the screen turns on but then goes back off immediately. It seems that proximity sensor is managed by the accelerometer combined with ai just like it was in my old OnePlus 7Pro. However, I could be totally wrong!

While on call I tried to use another phone`s camera to search for proximity sensor ( it is ir based , so camera picks it up).

So then, my suspicions are right..It's accelerometer+ai
I think it uses the camera too. If you try unlock the phone with the selfie camera covered, it will try to prevent it.
Likewise, if you make a call with your phone placed flat on a surface, you can get the screen to turn off by covering the camera.

Even when i am on call , phone just touching my ear , it randomly lets the screen turn on .
Also as far as i remember , always on display in the previous generations used to turn off when the phone was in pocket ( or screen was covered)
But here , the aod always remains on regardless if phone is in pocket or outside .

Yes you are right. It has an ir based one like note 10,20, s10, s20...
Samsung probably is wondering if they should make it invisible with no indicator. That tiny flashing circle has caused more commotion than a midget hooker in the playpen. Every new model provokes this same discussion... talk about a fixation
Using the camera sensor be prohibitive because of power consumption. It would still need an IR emitter to work properly. Net zero gain... and a lot of added complexity at best.
You can test the light sensor with CPU-Z, cover the space to the right of the front camera, that's also what triggers display dimming no matter what adaptive brightness settings you have.
my S20 FE does the same thing on calls. super irritating... i wonder if Samsung will correct the SD card slot omission mistake on the S22. they did the same thing with the S6 and fixed it on the S7
