I've encountered a problem on many custom ROMs for my Poco F3 and i haven't seen someone ask this question before. While being on a custom ROM, the edges of the display seem pixelated, like they're not smooth, in fact I can see the pixels on the corners. Did this happen only to me? How to fix it?
That can happen, and it's normal. The corners of the screen are rounded, but the displays themselves are still matrices of pixels, which means that they are, in actuality, jagged up to a point.
It means that the ROM maintainer did not create a mask within the android UI to cover/optically correct those edges.
Usually when someone starts including them most will pick it up. If it bothers you that much, you can switch to a MIUI based ROM instead.

I am planing to buy the mate 20, the regular one, and was wondering if it has any issues like the pro version. I read that it doesnt have the green hue around the screen, but it does have some white bleed (usually at the bottom of the screen). If you own one please report if you have or dont have any screen issues. Thanks.
well it has the lower edge bleeding symptom but it is very mild and not noticeable like pocophone .. i remind you this is normal with ips panels .. it needs a pixel peeping eye to notice the bleeding
anything else you want to ask about ?!
Mine has light breed at the bottom, left, and, right (more at the bottom). I can see it quite obviously when on grey/ brown backgound but it doesnt bother me much.

My mate 20 bottom have yellowish. Means its normal? It can be clearly seen when using white background and 100% brightness. If auto mode, sometimes can see the difference ???

i noticed that too but it is not noticable at all and considered a very minor issue that do not require you sending the phone back
ppl must appreciate something here quality control is becoming not acceptable those days when it comes to display screens .. all amoled screens exhibit an obvious color tint when looking at the phone or just angling it .. so think before you send it back .. you might get a worse phone .. you might not find another phone model with a better screen
i noticed the bleeding lower edge but it is better than most phones .. i noticed the all over yellowish tint of screen when colors set to normal but when i changed it to vivid cool whites are good and acceptable .. the lower yellowish tint is there also but it is minimal and considered a normal variance when dealing with screens .. the screen has a tendency to oversaturate red color and when you put phone into landscape videos contrast and colors increased abnormally but there may be a software fix for that soon
so you must know what are you dealing with and what to expect
also the mobile overheats when playing pubg on max for more than 15 minutes but i think thats quite normal when you pack the strongest processer and battery of that size in one phone
Thank God I don't have it.
The phone otherwise has a wonderful battery, easily last 7 hours sot during 19 to 24 hours charging cycle, very fast and stable l, camera is really good buttttt.... Emui is still crippled and stupid !!! For example comparing it to one UI beta I have on my note 9, HUGE DIFFERENCE in user experience animation and usefull features
I have a Mate 20 since one month and no problem with the mobile, the screen or anything else.
Actually it's normal for all IPS Panels and believe me you'll never notice anything not unless you will look for it. It's visible only in certain angles.
No problems here, anything good
I don't remember how it was on original KitKat 4.4 version but neither my last rom (CyanogenMod 12.1 android 5.1) nor the one I installed yesterday (LineageOS 17.1, android 10 which works pretty great) seem to have the ability to turn the black pixels off.
No matter how black the picture is, there is always some light being emitted. Although to much smaller extent than an LCD display. Could this be an software issue or is the hardware just not capable of doing it? It's OLED, isn't that what it's supposed to do? Have any of you guys experienced the pixel off thing?
I noticed the same while flashing ROMs on that thing in the dark. When it reboots you can notice some sort of backlight turn off and when it starts booting that little bit of backlight turns on again. It isn't noticeable at all in daylight. Not sure but my opinion is that it is indeed an AMOLED and the technology is just old for its age and doesn't compare with newer flagships.

But that's the thing, OLED literally is a technology where there's no backlight like LCD. All pixels light up individually. So there's no reason for whole screen to light up when there are some pixels who are supposed to be pure black.
I still think it could just be the software that's stopping screen from displaying fully black colours, but I am not exactly sure either. Maybe someone knowledgeable in this field could clear it up.
It's definitely OLED, the original ROM did not turn off the pixels correctly, but I'm using LOS 16 stable and it does turn off pixels. Also, since the phone is getting old I'm starting to see burn-in in the notification bar, so that definitely confirms it's OLED, just not as good as today's screens.

Interesting, but are you absolutely sure about that? Can you got into a dark room and trying watching a pitch black image in full screen? You can then lock the screen to notice any difference. Because in my experience it doesn't turn completely off.
And I've experienced absolutely no burn in, although that could be due to me not using phone that much but it's still strange.

Yep, just did it to confirm, it's actually black.
Here's a video of it, unfortunately I had to convert to a lower bitrate as you'd be able to see the burn-in on the top where the status bar goes and blacks would be a bit black but trust me, it's absolutely off and it's OLED.
So I finally got my f3, it has been perfect in every aspect, even the screen looks good, but the eye fatigue is simply too much.
I have tried to reduce DPI to minimum, reduce brightness, use reading + paper mode. After these changes it did get noticeably better, but it is still annoying.
I have Samsung galaxy s5 that also has an amoled display, but I don't get the same issue there. Also regular laptop and computer monitors are fine.
So anything to do on the software side to make it better? If not, then what other similar phone would you recommend that has a different screen.
Have you tried enabling DC dimming? For some people (not everyone) the PWM flickering causes some discomfort. I can't see any difference, but I'm glad the option is there.

F3 does not have DC dimming.
The option is there on custom roms, I assumed it was available on stock as well.

The text and screen looks somehow muddy compared to LCD screen. Text is not as sharp, or at least eyes feel so, and it is harder to focus to text and objects.
Yes, the screen looks impressive, but can't really use it.
LCD screens are always sharper than their OLED counterparts, but hey there might be a slight problem with your eyes or maybe you've got sensitive eyes. therefore, I can only suggest that you get an LCD device or test an oled before buying. btw I have no problem with the panel even though I prefer LCD panels (no burn in issues in LCDs etc.).
there is still one small thing that I have noticed, there a very slight white line/shadow under the black text and it's more noticeable when the text is bigger like when Im in settings, all the titles or texts seem to have that white shadow under them. Has any of you noticed that? I might make a thread for it later but I just dont care. the screen is waaaay better than my last OLED which was ROG phone 2 with red tint and huge bandings and awful black crush issues...

I personally use Syberia and have no problems with shadows under text.
Thankfully, I don't have eye strain.
Never had a problem on my end you might want to bust some glasses
Got my Sunny Yellow one delivered this morning so been playing with it most of the day. Initial impressions are very good, some are listed below. Feel free to list your own.
The fingerprint scanner was a little off but after an update came in i deleted my fingerprints and re-did them and its been fine ever since. Couple of times it hasnt worked but i think thats because the screen is so smooth/slippery that my thumb slipped on the screen as it was trying to read it.
I dont have a 5g plan or even 5g signal where i am to test but so far 4g speeds are exactly the same as my pixel 2xl and oppo reno 2 ive come from.
I dont really like having the "internet" tile, id prefer having them seperate the wifi and mobile data tab. Just seems strange to add a further click to enable/disable wifi when i want to instead of just hitting the tab.
On the home screen if you make a folder then the apps slightly overhang the edge of the circle which just looks odd to me, i wish they were all within the folder.
I wish there was an option of disabling the big clock on the lock screen. I have a picture of my partner on my lock screen and when picking up the phone id rather see her than her face covered by a huge clock
The phone got very hot when setting up and transferring apps/data from my old phone but has been fine since.
I love the screen and how smooth everything flows. I dont see any issue with brightness personally. Ill see how battery life performs over the coming days
Hollow screen sound is a bit strange
Nova launcher crashes which is a shame because I don't like the search bar forced at the bottom of the screen on the pixel launcher.
Camera is brilliant
Power button is in the wrong place and should be swapped with the volume buttons is.
Lack of screen protectors available to get delivered is frustrating but not Google's issue.
It's fast, smooth and had a great camera. The rest I am still get used to. Prefer it to my S21 ultra, maybe not loving it as much as my Mi 10 Pro.
The camera hump on the back really exposes the glass to potential damage. If I were designing the thing, I'd make the entire back stick out higher than the camera glass, and fill in the space with more battery.
The rounded edge screen is pretty terrible. There are optical distortions along the sides. The radius of the edge should be reduced to around 1 mm.
A little more width on the screen would be nice. This is 71.5mm. Nexus 6 was 74, which was a lot nicer. 80 would be a dream.
A little bit of border around the screen would also be nice so you have somewhere to actually hold the thing. Function should be paramount, not form, and especially not goofy/ugly form like these have. A bit of border above the screen would make space to get the camera out of the screen instead of the ugly hole. I also hate the rounded corners on the screen. Software rounded corners are ok, because you can disable them, there is no reason to force it with paint on the inside surface of the glass.

feel the same way with filling up the space with more battery... but then you have ppl complaining about how fat the phone is
Love it so far, so fast and fluid. As mentioned above it gets real hot, and was still discharging while using old pixel charger.
Camera is amazing the details captured are stunning.
Phone is very slippery to hold and would be easy to drop with the top weight of the camera hump. Tried to buy a case for grip and protection, and was told that they can until tomorrow because that was the day the phone was supposed to be delivered, but because of our crap postal service they sent a day early so that people would or should get them by that date
Real time translation works very well, even with the new update still seems a little buggy
Screen for me is fine for brightness I have high brightness mode widget and it is much brighter than the 4xl
I could buy pixel charger which I might take back because it doesn't seem to charge an faster.
My wireless car charger for the pixel 4xl charges this phone at about the same speed as the old wall charger, need to see if it throttles for heat though..

I agree, but it also would be heavy
This is concerning "Nova launcher crashes which is a shame because I don't like the search bar forced at the bottom of the screen on the pixel launcher." Hopefully there will be an update to Nova soon.
All the negative feedback on the rounded edges are making me consider the Pixel 6 versus the Pro. I think the base RAM on the 6 is fine. Giving up the Zoom is tougher to consider.

There as a day when heavy meant PREMIUM and light meant junk.
My laptop (lenovo), not even old, actually had some weights added into it to make it feel more substantial.
And so what if its a little heavier as long as it isn't burdensome. You can easily carry around several pounds without it being burdensome.

If you were referring to the rounded CORNERS, there will be kind-of software solutions for the rounded corners. Right now you can run "wm size 1440x2890" to reduce the display area (persistently). This brings the display area past the camera hole and past the rounded corners. Now normally, there would be a system property available to adjust the corners, however this one has multi-radius corners which are set in a config for systemui, therefore will actually require a rebuild from source to fix, but once that is unset, it should have square corners.
However the side effect of course, will be a slightly smaller display area. Still wider than the non-Pro, but less than it is now. Not that you need all that height for any practical purpose.
And for that matter, you could use the same "wm size" command to reduce the display width to work around the rounded edges. "wm size 1300x3120" pulls the display area all the way into the flat part and eliminates the optical distortions. You could probably establish a better balance that lets it in just a little bit and probably gives the same width as the non-Pro.

Nova Launcher was crashing for me but it seemed to be a clock widget I had previously and it wasn't displaying it.
I deleted the widget and rebooted the phone and it has been perfect since and all day today.
My screen now looks like my 3XL only longer, faster, smoother
I can't find a was to Turn off Always on Display. Ist ist me, or isn't there an option?
Thanks for the tip on Nova, might rebuild my screen from scratch with it too ID the issue. The pixel launcher without some custom apps and grid sizes is a bit of a jarring experience. Search at the bottom is all wrong too.

Have you gotten the small 70 MB Android update yet? Mine was buggy with Nova Launcher Prime, in particular, but after the update, all good.
I like the fingerprint reader better than the ultrasonic in my Note 10+. It's working much better and faster for me so far. Here's hoping that stays true.

.. is the sound u get when tapping the screen also changing depending on where you tap the screen; meaning it sounds more low-pitched in the middle of the screen and more higher at the top and bottom?

Jup. As this point I'd call it common knowledge, we have talked about this on XDA for about 9512 times already^^
We even have dedicated threads, the search engine is your friend here.
It has to do with how the screen has been bonded to the edge of the frame and what lies underneath the screen. It's also present on quite the number of other phones, like the new IPhone 13s.
And the beat goes on
thanks guys!
so lets get on to another screen issue (since i cannot find a display thread here): do u also have a reddish tint as soon as u slightly tilt the phone?

Nope, not at all. I just checked most colors and tilted my phone in every direction, and for some odd reason I can't seem to find any sort of color tint. Even my white stays white in a ridiculous tilt, which never happened before with a pixel phone. All my previous pixel phones went a bit bluish when tilted. .Maybe my eyes have gone kaboom sh*t crazy, or I won the lottery ticket of this years display.
Some people here claimed / talked about a yellowish tint of their display, even though that was more of a general sort and also present when the phone was not tilted. I'm not able to reproduce that, so there is not much more to say.
Do you have a screen protector by chance? That one might be responsible for tint if tilted.
