New 9T have a Display issues - Redmi K20 / Xiaomi Mi 9T Questions & Answers

I have two 9T, one is from 2019 05 and the second is from 2019 06. On the newer 9T i see under direct sunshine the fingerprint, on my older 9T i dont have this. Does anyone have the problem with the newer version? You can see it only on a bright background.

I fear xiaomi might use different panels for the k20/9t since they did not specify the maker.
I saw this fingerprint issue reported somewhere else as well, but can't remember where.
My 05 made 9t has perfect screen/coating.

Bought last week. I see the fingerprint scanner in sunlight. But I don't care tbh

Display issues
I have been using k20pro more than one year, but after the next update shows serious display issues. When i get calls then display don't wake up. Moreover a white line moves over the display. I have updated MIUI 12.0.2.0(QFKINXM). How can i fix this serious issue!

Redmi Note 7 Review

So, I bought a Poco F1 back in September 2018, I was really disappointed with the phone because of the touch issues that won't let you play games nor type and the bleeding issue with the LCD. This was one of the worst phone I have ever bought. So, last week someone in my family asked me to buy a nice phone in min budget, while seeking for one, I found only 2 phones that fulfilled the criteria, Zenfone M2 Pro and Redmi Note 7, but since my previous encounter with a Xiaomi phone was not good, I thought that I will go with Zenfone, but after watching the reviews and asking various people on social networks, I at last thought about giving Xiaomi another chance (which I always do), and they did not disappoint me.
1. Touch Issue - No issue related to touch, only the lcd is quite sensitive just like Nokia 7 Plus's screen.
2. Bleeding Issue - I did not see any bleeding issue with my unit.
3. Software Issues - The MIUI 10 skin lags a lot, but I am sure that they will fix it with an update.
4. Camera - Camera is real bad, back camera is average but no details on zoom. Front camera is real ****, no details, it smoothes the skin even when AI and face retouch is off.
5. Performance - As the SD660 should perform, only few lags here and there that can be fixed.
6. Heating issue - Yes, there is a heating issue, while charging as well as while playing games, my Nokia 7 Plus had that issue too, but was later fixed with an update, maybe a custom ROM or an update can fix that too.
7. Camera2API - Full Support of Camera 2 API.
Conclusion -
1. This is surely the real successor of the legendary Redmi Note 3, and I recommend this phone, even when I said that I will never buy a redmi phone because of Poco F1.
2. Other Software related issues may be present, I only checked for the major ones, and it passed the test, I hope that other issues can be solved via an update.
PLEASE FIX CAMERA (4) AND SOFTWARE ISSUES (3) ASAP.​
Seems like you got weird bugs that made the phone hot
Mine, running on the stock MIUI that came out of the box, never get hot, even when charging and playing PUBG at the same time
It also has ARB, be careful when downgrade ROMs and MIUI

Mines on the EU rom. Not hot either except when I use GPS and the screen stays on for extended periods

Need a replacement phone after Mi A1

I need a replacement phone. the A1 has been good but the battery life is now no good. Also, the screen brightness is very low. I am not complaining it has a been a good phone.
I would like a new Android one phone. The A3 would have been good for the 720 screen is a let down. Two questions:
Can anyone recommend a good Android One phone?
Has anyone made the change to Redmi phone after Android One. Is the redmi UI okay to live with or is it a pain?
I would go for a Mi 9T or the Oneplus 7T. Without a budget it's kinda hard to help you out.
The MIUI seems ok for me although I prefer stock Android. I don't know Redmi UI.
Also, I've read that the A3 screen it's not a big let down for those who came from the Mi A1 - also, it's brighter.
I'm thinking about buying the Mi A3, it's just a little bit better than the Mi A1 (but I don't care, never experienced any lag in any app), and it should have almost twice battery time, charge twice faster, more photo capabilities, more system updates (soon android one 10), and it's cheap !
My next phone needs to be 5G ready it will either be the A3 (version 2) or more likely the A4 next year.

Thanks, I have no real budget but I am loath to spend more than about the price of an MI A3 or similar ($250 US) on something I know I will ditch in about 18 months because the battery life diminishes or I break it of lost or whatever.
I saw the MI9T but I can't justify the price and the gimick selfie camera goes against what I look for. I don't want something that has a motor that can break, or get jammed. But that did lead me to the Mi 9 Lite which is about the right pricepoint and ticks most of the boxes I need. It also has the bonus of being able to accept and A/B slot rom if something stable arrives to load on it. So thanks for the tip.
The other phone I saw was the Redmi Note 8 and that looked okay, but seems to only have BT4.2, will be a little more battery hungry with the IPS screen. It also lacks the NFC option. But I still might get it.
If anyone has knowledge of some decent phones in the price range with decent camera and battery that will accept an AOSP or similar Rom and is likely to get a quality ROM soonish, please let me know your thoughts.
I replaced the battery and it is working well after that. I think my A1 will last me another year or 2.

That is good to know, but my screen is also starting to fail. It's maximum brightness has diminished to a point where I cannot see the screen outside. Also the screen has taken on a very warm hue.
If it was just the battery, I would probably do the same as you, but unfortunately, it will just be more simple to get a new phone.

Regarding the warm hue, you have confirmed you did not turn on Night Light ya? Night light reduces the blue light and it is more pleasant to the eyes.
And regarding brightness, I saw a comment in the thread below mentioning that between Oreo and Pie, somehow Oreo has a better max brightness than Pie.
https://forum.xda-developers.com/mi-a1/review/outdoor-visibility-max-brightness-t3679694
I did not try downgrading it to Oreo myself but I also remember the brightness issue I encountered after a certain upgrade.
I used to set brightness at about 30% but after that certain upgrade, I had to now crank it up to 70% at the brightness slider while using the phone indoor.
My wifes mi a3 arrived yesterday and I must say for the money it's a little beauty. Feels solid. 720p doesn't really matter and does not bother.
Phone is fast enough for daily usage and gaming. Battery life is great. The camera makes good photos too.
Not bad for 140 bucks !

Thanks for the insights and thoughts. I did consider the Night Light but that is confirmed switched off. I went out and had a look at a few phones last night but I really didn't see anything stand out that made me want it.
I might try an AOSP ROM on the A1 to see if that helps screen. Maybe that can get me through until the next round of phones come out.
Try replacing the BN31 battery. ~$10 only

I'm using my MiA1 since September 14, 2017. The battery's BN31. My MiA1's battery capacity (true) is still ~2800mAh, 90% of promised/original. I've been using 5-85% charging/discharging or better 10-80%, always charging with back-cover up and radiating in Fan/ A/C air to keep temperature < 40 dC.
The Battery BN31 IS REPLACABLE. You can get on Amazon/ Alibaba/ Flipcart/ many more. The price is ~$10.00.
I'm using Android 8.1.0 (Most Stable) un-updated since November 2018 when the choice was to Update to Android 9.0 (and probably get ruined) or REJECT Android 9.
For the last 1 year I faced NO problems. No Need for so called endless Security Updates etc (which is a racket to keep you on tenterhooks).
In fact, my MiA1 is better than NEW, except for some scratches.
I expect it'll be Good Enough for the next TWO YEARS!!
If at all, I'll get a New Phone (Top Range) as an additional one.

Still no Always on Display?

The title says it all, am I right in thinking that OnePlus have still not added an Always on Display with the OnePlus 8/8pro.

I think you are right.
No review or on the launch event mentioned that it has.
Hopefully the will add the feature later in an update.
It’s a disappointment for sure, they have been ‘working on it’ forever.
Of course they haven’t really been working on it just saying they have.

Aod have been approved after first round of IDEAS. So now it is on OxygenOS team's roadmap. Just wait, i guess it will be here soon. At least for OP7 series.
They already said that this will happen.
Sent from my HD1907 using Tapatalk
They have said this before though, more than once.
No I don't their stance has been that. They have consistently said that they didn't want to do this because of the battery hit.
Sent from my HD1907 using Tapatalk
The most recent comment from them has been 'It's on our roadmap'
Not a confirmation that it is coming, roadmaps change all the time. Let's not forget there was an always on display briefly on the OnePlus 6 before they took it away citing battery concerns, the few people who got to use it said that the battery hit was not obscene at all. I suspect there is another motivation for removing it and never adding it again, maybe something hardware related around the screen?
Another overlooked benefit of the AOD is it also allows you to see and use the finger print sensor without waking the device, currently on a One Plus you have to wake the phone and then unlock whereas on say a S10 or S20 you can just unlock right from the AOD.
Unlocking the screen without turning it on has nothing to do with Samsungs AOD though. Samsung uses an ultrasonic fingerprint sensor while the one of oneplus is optical. While the OP needs light work indeed, Samsung doesn't.
mkbhd review has shown aod on oneplus 8 pro.
What do you think about "Oxygen AOD Mod", or "Always on Amoled"? These apps are available in the Google play store. They seem to work well.

OnePlus 8 Pro Screen Issues

How worth is it to buy the OP8P right now in the US ? I am concerned about the huge number of screen problems that are coming up for the device.
I do not change my devices frequently and in need of an upgrade from my current ~4 year old OP3. I need an unbiased opinion on this, can anyone help ?
Anyone from the US purchased this device recently? I do not want to go through the hassles of replacing the device and want to use the device for a long time.
I did from Amazon. No screen issues. battery life had me worried but it's actually descent coming from a pixel 2 xl.
Camera also had me worry... Hit and miss here. The HW is there but software isnt doing the best all the time.
Google cam app seems to be doing a bit better but you don't get the cool macro option. Nights cape does a pretty good job.
Main issue is contrasts being cranked all the way up and images a bit dark overall. Doesn't seem great with nature but works well for buildings and such with angular details

May I ask, when did you buy it ? I'm just trying to figure out whether it was a problem with the earlier models
Got it a week or two ago when it just became available on the Amazon site.
256gb blue model.

Go-to YouTube and search for key word's " oneplus 8 pro screen issues ". You'll then be presented with indian customers being able to see a green tint when the brightness is turned down to zero in a pitch dark room. Hardly something that one does on a daily basis ,? .
Quite a few threads about this issue.
Personally no issues, early adopter too

Should I get the OP8 PRO?

Just looking for thoughts and opinions...
I am -very- new to OnePlus and have recently purchased (and returned) my first TWO OnePlus devices. I bought a 7 Pro model on amazon that was supposed to be a Gm1917, but turned out to be a Gm1925 (t-mobile), and returned it. Then I purchased a GM1910 (chinese non-carrier/GSM), but when received that one, was an HD1910 (7t Pro, not a 7 pro... which by the way won't even show up on OnePlus' website if it detects U.S. Ip address). So.. I returned that one too. I really want a One Plus Pro 7 Unlocked / Carrier free but it seems downright impossible to find one that is new. After two failed attempts at getting one, I'm getting disheartened. I specifically chose the OP7Pro because it seems to have everything I want from a post-purchase development side (working TWRP, Magisk, and Official Resurrection Remix Rom), as well as the fact that I already bought screen protectors and a Newendry Battery Case. I loved the camera's Pro functions and just about everything else... so here's my question/s...
Should I just buy the 8 Pro direct from OP and hope that TWRP get's up and running , as well as a Resurrection Remix port? Is the camera functions the same as the 7 Series? (I absolutely love the ability to select separate focal point from an auto-exposure point). Is it reasonable to believe that OP8Pro will indeed get an official or even unofficial but well-working TWRP?
I am so tired of dealing with misrepresented phones on Amazon, but from what I've read, Oneplus has no intent of producing more OnePlus 7 Pros and since they are all out of stock, it seems my only option is to keep playing Buy-and-return games with amazon and ebay until I actually get a phone that actually matches its listing, or to just buy a OnePlus 8 Pro.
Thoughts?
(Sorry if this is in the wrong place... feel free to scold and educate me if so.)
I would say the 8 Pro for the win! Had mine since launch and it's best device I've had. It's ultimately your call... Cheers
Go with oneplus 8 pro . I love mine. And I have latest greatest even after 8t. Still better option . I bought mine amazon .....unlocked and u will be able to twrp . Magisk etc ..
I'm with the above people... The OP8pro is a winner.
Yep, OP8P is great, I'm enjoying every minute using it.
It's fast, smooth and offers good battery life
Good luck
Don’t mean to hijack this thread but the in2025 is the USA all bands supported model dual sim unlocked right ?
8 Pro. Period.
Only thing to pay attention is model for the region you live in.
Try Swappa. Check seller ratings before purchasing too.
Well, seems to be a pretty clear cut decision for everyone. So I pulled the trigger on the OP 8Pro.
I bought direct from OnePlus this time so no false-title shenanigans. I did check swappa as well as a few other re-sell sights for the 7 pro first, as suggested, but most of the ones I found admitted to having slight burn-in at the top so.. the 8 it is. Should be receiving it today. Thanks for all your input everyone!
Had the 8 pro it's a great device, if you want a better camera though go with another phone, great all round device though

Nice to hear, I hope you're enjoying it mate, don't forget to share your experience
Well... Initial impressions...
I prefer the pop-up camera on the 7 more than the screen built in 8... That little black hole distracts the everliving bawhoosits out of me on the status bar... Buuuut... I can easily remedy the status bar placement with a few different xposed modules if it really bugs me later.
One thing I really like is fingerprint sensor. Seems much more accurate (or maybe inaccurate?) than the 7. That is to say, it actually registers my finger without me having to press it 4 times.

Download energy ring, it's on the play store, then remove the battery icon. I couldn't have this phone without it.
Free app btw..thread in the themes section.
Finger print is superb.
Is it still worth buying right now? Talking about the camera (versus P40 PRO or similar). I'm especially interested in the camera. Then , screen, batter. I know screen is amazing.
Price tag would be 850 USD
People say that camera is better on P40 Pro. The new 8T is not better then 8 pro. Is better then 8.
The OnePlus 8 Pro has some pretty bad WiFi / Bluetooth interference issues that are somewhat (though not fully) resolved in Android 11. So if you rely on VOWiFi calling with a bluetooth headset, this is not a good phone for you. Some of these may be related to the Qualcomm SOC / hardware and may not be fixable
Also if you search the site, you will see many comparisons of people getting all around better wireless speeds on the 7 Pro or even 6 series or other phones because of these issues.
I have kept mine, but I also kept my OP7Pro and have had to use it in cases where the OnePLus 8 wouldn't do VOWiFi (voice cutting in and out).
Also someone asked about dual SIM -- in the USA, I believe you need the Android 11 beta to use this. I have not tested it, but saw tons of people griping about it.
I am hoping the official Android 11 build fixes the remaining WiFi/Bluetooth issues, otherwise I am going back to OP7 Pro.
Everything else about the OP8 Pro is very nice.
Yes, you should.
