It is most obvious to me in low light (or a pitch black bedroom) with the brightness slider on down low. It will even show on this XDA website. I really hope they were a bad initial batch as the 2021 11" is fantastic value.

The difference between the Pentile and AMOLED screen is highlighted in this video:
[Lenovo P11] mdurkin:
i just re-ran the test in complete darkness and can now see some uniformity issues in those low greys. I'm not sure it's going to be a problem for us as it will be mostly used during the day, and the issues are invisible with any normal level of lighting. It is a shame though I agree, as those issues just shouldn't be there at all on an oled.
[Lenovo P11] mardon85:
I watch a lot of TV films in bed and my Mrs is asleep so the light is off so it really did bug me. It manifests itself in loss of detail in low light scenes. I agree in your usage case it'll be less of an issue.
[Lenovo P11] russy23:
the only thing ive noticed so far, havent used it alot mind you, is chrome when you at the page before you open a tab looks bad, but when your loading a app the pure black looks top notch..

so anything with grey in looks bad?
[Lenovo P11] mardon85:
In some scenarios yes. But for the money the 11" 2021 is hard to beat! 90Hz oled and SD870 SOC!! Amazing value.

I'd even be happy with the £510 I paid for the 12.6" if there weren''t so many software gremlins. It seems perfection is hard to achieve for Lenovo?
[Lenovo P11] lobo111:
Anyone knows if finally gonna be a Global Rom for this tablet (Xiaoxin pad pro 2021)?
[Lenovo P11] mardon85:
Not likely at all. Unless you specifically need another language the current Chinese rom works well.
[Lenovo P11] lobo111:
I am from Spain and I have managed to change part of the system language using adb and an app. I am also having problems with notifications and microG that stops working. I think the security app is the problem and since zui 13 it doesn't work
[Lenovo P11] mardon85:
Yes if you factory reset it will be an issue. The developers are aware of it according to the Chinese forums.

I haven't factory reset and the security app is still functioning for me thankfully on my 2021 pad pro 11.

Lenovo have brought in quite tricky region locks recently. Unfortunately you're going to have to play the waiting game for a while.

I have to send my P12 back to China due to my impatience.
[Lenovo P11] kubis111:
hi, have you fixed the multiuser settings?
[Lenovo P11] Beacon101:
I bought the xiaoxin pad pro 2021 with fake global rom. Bootloader is unlocked OOTB, and my widevine is L3. To get L1, can I just locked the bootloader or I have to flash to CN ROM first and then lock bootloader?

Thanks
[Lenovo P11] mardon85:
Flash CN rom and then lock bootloader.
[Lenovo P11] kubis111:
hi, do you know if CN ROM multiuser can be set? I can't find it in the "global" rom. Thanks
[Lenovo P11] furtz83:
and how to do that?

I bought my from aliexpress with this Fake Rom also and the bootloader is unlocked
[Lenovo P11] mardon85:
There's a guide on here.
[Lenovo P11] llexl:
Hi.

I received my tablet with a "global" firmware. Then I installed the original one and updated it to the latest version. The bootloader is still unlocked.

I want to change the system language. I know that in ZUI12.6 it is possible to do this through the SetEdit application and the System_locales line - part of the menu will be translated, but most importantly, the applications will be in the required language.

But the problem is that there is no such line in ZUI13 and its addition does not change anything.

I found the closest solution - via ADB Change Language app + ADB. But this only works until the first reboot = (

Perhaps there is some way to change the system language (so that it is in applications), and leave English in the system itself?

It's not a pentile display in Xiaoxin P11pro2021 as it has an equal amount of RGB subpixels, been debating this with Ron Meters owner of OLED-info org.

Pentile display is useally a Samsung trickery, where they often will put more of certain subpixels to elevate certain things.. also why "Pentile" is a Samsung trademark...

fx if you have 2 green subpixels for each red and blue..

None of these (Samsung E4 or Xiaoxin 1600p OLED) are pentiles displays as per-say..

Weird how people are running around with that line, and likely have no idea what a pentile display is.

Been comparing the Xiaoxin 1600p RGB OLED versus a gen E4 1600p AMOLED and it's a mixed result and some does the Xiaoxin better and some does Samsung AMOLED better, but to summon it's certainly not a bad 11.5" OLED display Lenovo er using when you have the price in mind, quite the contrary.

in some tests, the Xiaoxin 1600p RGB OLED actually outperforms the Samsung 1600p AMOLED.

fx the ability to recreate "red".. here I at times often sense the Samsung E4 are tilting into orange, and not sure if it's down to a tad smaller "Red" subpixels versus the Xiaoxin 1600p.

You can see here where I put both displays under a 4K macro view.

a gen E4 s AMOLED 1600p display (blue s-stripe variant) and the Xiaoxin at around 50sec.

here with some colorslides

also not sure why you're claiming it ain't bright for an OLED.. I'm getting above +600nits on my unit, and that's only with the slider and the max brightness setting activated in settings... quite solid, though the P11pro2020 60HZ panel could be lower, as Notebookcheck saw way less in their review, though I don't recall they have had a look at the P11pro2021 (SD870 90Hz).

Samsung is just about to release products with their new-gen E5 AMOLED panels, though I don't know if those will be the case with the coming tab S8+ and their behemoth tab S8 Ultra

Here are some color slides at the end' and how the Samsung AMOLED subpixels on their blue-stripe panel, often choke in certain full-color slides, mainly all red. (1:50 below) and toogles into a an orange tone while the Xiaoxin is able to keep it together' - a tad better..
[Lenovo P11] mardon85:
When did I say it wasn't bright? Both panels have perfectly acceptable brightness levels.

I have spent more time with my 2021 Pad Pro as my 12.6 had to go back to China for a reflash.

In that time i've established a few things.

The dirty screen effect is an issue but not one I see day to day anymore.

The biggest problem I was encountering was the black crush in dark scenes of films. I've actually found out what the issue is. I use JustPlayer for all my content as it will play all HDR containers inc Dolby Vision. What I was noticing is the video plays fine for about 1 to 2 seconds then the brightness/contrast changes and it is at this point that the images turns to trash. I have discovered if I set the screen to 60Hz this no longers occurs.

Since i've made this change when watching media i'm actually pretty pleased with the Pad Pro 2021 and value wise it is absolutely the best tablet on the market.

However... The E4 panel in the 12.6 is hands down better in all scenarios to my eyes. In high bitrate files around red objects the 11" would look pixelated and distorted. (I will try and capture this). This does not occur on the 12.6, I also found the 12.6 to be brighter in HDR.

Colour vibrancy (with all settings between the two tablets equal) the E4 panel is greatly increased. Images and video pop much more.

Pentile or otherwise the 12.6 screen is sharper. I don't know why as the PPI is actually lower on the 12.6 but it is clearly (excuse the pun) sharper.

I should be getting it back tomorrow. I'll try and capture some of the examples (if possible) side by side.

Something to note, it seems your comparing a Samsung S6 E4? I belive even the S7+ has a dimmer panel than the e4 in the Pad Pro 12.6 (P12 Pro) so your results although interesting are not valid against this newer tablet imo.
[Lenovo P11] vipboy247:
How can register lenovo one id without china number? Im using lenovo tab p11 pro 2021 j716f. And i also waiting global rom for this.
[Lenovo P11] 3bo0od1997:
On your opinion, which is better to buy, Xiaoxin Pad Pro 2021 11.5inch or Galaxy Tab S7?

Tab S7 will cost me 100$ more in my country

I only need it for streaming so L1 support for Netflix is mandatory

Is pad pro panel better than s7?

May you give me screenshot from Netflix app (Player Specifications)
[Lenovo P11] mardon85:
The S7 doesn't have oled. I'd go OLED personally.

The 12.6 has the best netflix support out of all of them offering full Dolby Vision.
[Lenovo P11] DaneLaw:
The Tab S7 is a lot more OS polished.

The Xiaoxin P11pro2021 on native ROM is maxed 1920x1080p Netflix and no HDR sadly, I don't know if a later OTA update will implement it,.

I reckon I have the Netflix player specification posted above, just under the UFS3.1 values.

Here in Scandinavia the Tab S7 and S7+ are very expensive, just the cheaper S7 and its accessories like the keyboard is 230USD (1499DKK) and the Tab S7 folio is 85USD (550 DKK) and the Tab S7 is 825 USD (5399 DKK) for the base 128GB wifi entry version, so its get expensive very fast.

The Xiaoxin P11pro2021 is shockingly good value for the combo of these parts-

It's a flagship device with a mediocre OS, here Samsung One UI is way more polished but one thing that puzzles me is the video-output of the Xiaoxin.

as far as I can tell it looks to be a 4K video-out signal.?? (but sadly in a limited aspect ratio, like 4:3 (open question for people taking the newest OTAs, is this being fixed on later OTA revisions, or is it still 4:3?)

on Samsung and fx DeX, its max-resolution limit are still 1440p (in 16:9).

I don't know what resolution Huawei has on their PC video out, but I really like the high res the Xiaoxin and I can plug in a USB-C to HDMI cable to my LG 4K OLED and see science & space documentaries in high res. from sources like Magellan etc.

One thing the Xiaoxinp11pro2021 does not perform too well in, are secondary displays, those where you wanna use 1 TypeC cable so the tablet both supplies power and video.

I tested with a Blitzwolf PCM3 15.6" and the Xiaoxon P11pro2021 socket could only deliver like 4watt (around 0.8A at 5v), before it chokes, so that is a very dim second display and only a brightness around 2/10 ...I can of course supply power with a power bank to the display so the Xiaoxin only is delivering video and that works great, but here the Samsung tablets and their DeX are able to deliver way more wattage on their USB-C video out to a single type slave display and up around 7 to 8 watt (5v at around 1.3A).

The Xiaoxin (Lenovo) does have a nice feature for Windows devices where you can use the Tablets awesome OLED screen' as a wireless extra windows display, and something XDA user "Mardon85" made a thread about here on XDA and why I took notice.. Called Project Unity as I recall.

The Xiaoxin P11pro2021 1600p OLED screen is way better than the 1600p LCD IPS found in Tab S7, I also reckon the overall build is better on the Xiaoxinp11pro2021 and its lighter 485g vs 498g while being both a bigger 11.5" versus Tab S7 11" and thinner 5.8mm vs 6.3mm and Xiaoxin P11pro2021 also looks to be quite a bit stronger then Tab S7 comparing Antutu scores and with the price in mind, it made XiaoxinP11pro2021 unreal good value. judging it from my corner in the world and prices here. .
[Lenovo P11] DaneLaw:
When I have seen it, it's been down the Lenovo's UI Android (ZUI) skin, and its an android-skin-feature, where the OS will let things underneath glow thru, and transparency like we know from subtitles and the subtitle box.

Are you sure that ain't it, as Lenovo ZUI Android skin has a certain transparency feature, where it will let things behind glow true..

Fx when you are in dark mode, some scenarios will look like this "IPS glow" we all know from IPS layered LCDs, where you can see fx edge blooming or local blooming. depending on if it's a FALD or an Edge-based LCD, but obviously not something you encounter on OLED.

Some examples of Lenovo's ZUI transparency feature, where the OS in some settings will let something underneath, shine through - that can give that blooming effect we usually asses with LCD glow/blooming, but here on OLED it goes without saying it is with full intent and a ZUI feature where there is a harsh transparency feature were pages, menu, etc, will shine through in certain scenarios.. - like my examples below but simply a UI skin feature.

If somebody has a test or behavior, for example, what they are encountering, please share as all the times I encountered it, it has been a feature of the ZUI skin, and with full intent and a feature of the Lenovo ZUI skin and has nothing to do with the OLED screen..

View attachment 5492235

Been testing this OLED display from Lenovo for many days and I like it a lot and Im glad that it ain't another GenE3 or E4 materiel AMOLED blue-stripe variant -, as I already have a few of those and I like to get my hands on other OLED panel types.

Compared it with a greyscale slide, with finer and finer lines in transition to black.

10.5"AMOLED 1600P and 11.5" 1600P OLED Xiaoxin (looks good as far as I can tell and performs just as solid as Samsungs AMOLED.. see for yourself below, transition to black with finer and finer lines)

Overall I'm quite impressed with the OLED panel in the Xiaoxinp11pro2021 and in certain things It performs better than Samsung's current line of blue-stripe AMOLED like fx the color red. (at least in my crude test) and as noted above, it ain't a pentile OLED display as it carries an equal amount of RGB subpixels.

I often use my P11pro2021 without the keyboard and only the magnetic kickstand and here I often would like something to protect the screen.

I find the original p11pro magnetic Folio works great if you stack It underneath the kickstand. (obviously not intended as, but it works good)

all the magnets and hall sensors (for open-close reg) are very strong.

stacking the org. Folio with the kickstand, though the weight and thickness obviously take a hit.

[Lenovo P11] 3bo0od1997:
Thanks bro, l want this tablet only for Netflix & YouTube, so i have one question left

Is this grey color appears in streaming or watching content or just in menu and pages in system?

I see it clearly in 1st image but in 2nd image it disappears, so it's not seen constantly, am i wrong?

And from your experience, this is a ZUI feature not a problem from panel used in this tablet

(I hope you understand me, and forget me for my bad English 😅😅)
[Lenovo P11] mardon85:
You don't really see the grey issue in content.

Be aware there have been posts recently of people loosing their Widevine L1 cert out of nowhere. This means no HD netflix.

If you can stretch to it the P12 will be the better buy. Don't get the Global Flashed Chinese version. Ether get the official version or the Chinese version with Chinese ROM.

Also be aware that if English is not your native language the Chinese Zui only has English and Chinese Language. There is a 2021 Global version but it does not have Widevine L1 cert so no HD netflix and no OTA updates.
[Lenovo P11] CptanPanic:
I have never bought an tablet from aliexpress, but am in the market for a new OLED tablet and the X Pad Pro seems like a great deal. It is not clear from description, but will it come with global ROM that I can change to english? Does it come with Google Play Store, or is it easy to install?

Thanks.

Fair enough. The 2021 is decent but do be aware of its shortcomings. If its just for media you may be better with a Global 2020 version as that has full widevine and Dolby Vision support for Netflix.

Short answer: you guys want the CHINESE stock ROM (Chinese/English) if you want widevine L1 (a prerequisite for HD streaming: Netflix, Prime, etc. will be 480p on the International ROMs).

international = very very bad. Only YouTube runs in FullHD.

[Lenovo P11] MrPool1:
Hi, i'm new here and found this site when I was searching about issues with my xiaoxin pad pro 2021 (model tb-j716f).

I was receive my tablet with the global rom, and for this reason it doesn't have OTAs and widevine L3. According to I understand with this post, one option is change to CN version rom (I think that I have my tablet unlocked) and this version has CN and english language (I hope that I can switch at beginning to english). In this way, my tablet can obtain OTA and widevine L1 (I dont know if the last version have android 11 or 10).

If this is correct, there are some tutorial and link to the rom available? Thanks in advance and sorry for my bad english.
[Lenovo P11] DaneLaw:
what is that "grey" issue your talking about?

sofar I haven't seen any "grey issues" at all, quite the contrary, cycling thru aspects of transitions of white to black = with finer and finer grey lines, I see an ideal grey-toning, and like my AMOLED E3 and E4 1600P displays. (Xiaoxin 11.5"pro2021 on the right)
[Lenovo P11] mardon85:
I'm really happy for you that you dont see it. I would suggest don't go searching to see something if it is not immediately obvioius.

However I did a lot of low light reading with my 2021 P11 Pro and it often manifested itself when the brightness was turned down low. Infact this very website was quite good at displaying the issue. The dirty screen would also be obvous on dimmer viewing of dark films.

If you dont use your tablet in this senario it is a non issue.

Having spent more time with the P12 pro I can confrim the screen is night and day better. I would find the grainy fringing arould colours especially red based ones very distracting. This does not happen in the slightest on the P12 e4 AMOLED. Yes a full screen red test patern may lean more toward the orange end of spectrum compared to the P11 but I don't watch test paterns, I watch movies and TV.
[Lenovo P11] Cypresser:
Very good, this is essentially bwhy I came here. However, not to move topics, albeit, does Lenovo put some sort of actual spyware on these?

How I define Chinese spyware. Hardware or software that in any way reports to the CCP.

As I am starting to wonder, even if they did, what would be the benefit of this outside of their region? They have no legal jurisdiction outside of their boarders. They don't know what my work is (government to plumber to McDonald's worker), so what would they do with random information? There is just too much data to process even for machine learning and deap learning systems.
[Lenovo P11] mardon85:
Hard to say ether way. I doubt they care about you as an individual (sorry) its more about the big data just like Google or Amazon like to collect.
[Lenovo P11] Cypresser:
that's my point. I could be a tech manager, but if I buy the tablet from an American who bought from China from eBay, why they don't know who I am nor do they know that I was interested in that product, so how would they even notice spy on me? It just doesn't make sense.
[Lenovo P11] mardon85:
That's what BIG Data is, its just the mass collection of Data. Google uses it for adverting. Who knows what China may or may not use it for.

Personally I'm not bothered.
[Lenovo P11] mardon85:
For someone that clearly enjoys oled are you really telling me you can't see the grain effects on red colours?

It's 100% not the os transparency effect. Dim the screen and look at this web page and report back.

The issue with films is largely fixed by setting the screen to 60hz. 95% of the content I watch is in HDR and their is a bug that elevates the black after a few seconds on certain players. My go to is "justplayer". Again other people are reporting the same.

Perhaps they fixed some off the issues I'm seeing at a hardware level between yours and mine.

This isn't opinion or preferring once device over the other due to which I own. It is a genuine issue on mine and other people's devices.

Also who cares if it can do 900nits if you activate the light sensor, just like the red test pattern it's not something you see in day to day usage. Know one sits consuming content with a torch pointing at the sensor. They both output 600nits which is totally fine for indoor use.
[Lenovo P11] Temjinck:
From reading the thread, can I presume that it is much more desirable to buy the tablet straight from China (i.e. taobao) with native Chinese ROM instead of an unofficial global from?

I really needed the tablet to run google play services and google play store flawlessly, including games that use play game services for profile backup. Also good to have is OTA updates and streaming apps.

Otherwise, what other limitations am I looking at with the Chinese ROM? Someone talked about regional locks here, what do you mean by that?

I've used a Huawei Honor 5 with Chinese ROM and google play service/google play store simply do not work consistently. Just don't want to deal with this problem again.
[Lenovo P11] Wualk:
I can also confirm what @mardon85 has noticed and described. Especially in a very dark environment (e.g. in your bedroom in the evening) when watching Netflix there is a noticeable "flickering" of blacks/greys in the screen. This happens mostly when watching a dark movie scene and when you have turned down the brightness.

I must also thank mardon85 because your solution worked. Previously I had disabled auto brightness etc., but this did not help me. Lowering the refresh rate to 60 did solve it for me (and just for the record, I have also changed the image settings from vivid to natural).

And no, it has nothing to do with the transparency overlay. That works as expected. Kinda.

Not noticed it personally and I've come from the 2021 P11 Pro so knew what to look for. It there is an issue it's certainly not the same one and not something I've seen. I'll check again tonight though.

Was possibly a software issue in the first un patched ROM which is what he's running in the review.
