[Lenovo P11] DaneLaw:
It was the message in between yours #13 that referred to low brightness, (my bad).

as sustained +600nits certainly ain't too shabby on an OLED-based tablet.

I am able to go a tad higher on Samsung E4 1600p AMOLED panel, but only if I flood the light-sensor and trigger the short sunburst-effect.

but as a plain slider brightness (sustained), the Xiaoxin actually goes higher than Samsung on the brightness slider.

If you can try to measure the brightness on the P12pro.

I don't know if you got a bad batch on your P11pro2021 and, your definitely not alone with the phrase "Pentile display" - many reviewers on YT.. uses that phrase on this Xiaoxin but when asked under their videos' if they actually know what pentile display is and why they conclude that its a pentile display on the Xiaoxin, . its mostly silence or "I have heard it from another YT'er".

btw, I also have an LG 2017 4K OLED (55"), so that black crushing you are referring to, I would be able to replicate if you show some examples.

Here is a WOLED grid on that 2017 4K LG OLED.

precarious that LG's 4K WRGB OLED grid arrays still only let 3 of the 4 WRGB subpixels be lit a once. (not sure if that limitation is still the case on the newer WRGB OLED panels for TVs from LG display, but I reckon it is)

- below macro is at the same resolution as on the Samsung E4 1600p AMOLED and the 1600p OLED macro view in the above-posted vid, so it gives a good indication of how big the WRGB is OLED pixels are on these 4K TVs in regards to the OLED RGB pixels on tablets.

I haven't noticed any black crushing on my Xiaoxin and also have access to two Samsung E4 OLED panels.. the 10.5" 1600P in fx Tab S6 and the 12.4" in Tab s7+.. not sure what panel are in the P12pro as that one is obviously bigger 12.6" then S7+ that is 12.4" but it is labeled as an E4 AMOLED so same gen as the 10.5" and the 12.4"

as mentioned some things the Xiaoxin 1600p OLED panel does better then Samsung E4 gen with its blue stripe AMOLED, and in some aspects, the Samsung does better.

fx if I put a test pattern with very fine lines beside each other.. I see more dirty screen effects on the Xiaoxin than I do on the Samsung E4 panel.

If you can' try and take the app "Screen test pro" on both and go into screen color test and put the brightness slider on max with the setting "brightness enhancement" active and do the same on the P12pro, and take a side by side picture.

If you see the same effect, on the P12pro 12.6" E4 AMOLED panel, as I do and they are worse in reproducing "red", than the OLED panel in Xiaoxin.

here is a 10.5" 1600p Samsung AMOLED panel on the left, found in fx the 2020 flagship S6 and Xiaoxin 11.5" 1600p OLED on the right both with the app screen test pro and color slides.

Samsung E4panels often choke into orange.

I also wondered about the p12pro as that unit was up for sale' when I went for Xiaoxin p11pro, though the p12pro keyboard and accessories like stylus were not present at that time.

but in my mind, the p12pro made little sense as it was so much more expensive.

I really didn't need another big Android tablet, now that all my older books also run Android, like Surface Book2 and the 2x Porsche Books,.. that are 13.5" and 7mm thin and weigh around 700g and works well as huge Android tablets, though sadly not OLED..

The Xiaoxin P11pro2021 was facepalm good value around singles day and BF and still is and was actually very close to CN sale prices, so wicked good value not least here from Denmark with tax + 25% danish VAT, and often results in some of the world's highest consumer prices and overall livingcost.

Fx on Lenovo DK official atm.. the older P11pro 730G 60HZ from 2020 cost from 4299 DKK (+655 USD) and thats the base wifi entry version 128GB, so quite high prices here on somewhat dated 2020 hardware, when the older 2020 variant is almost double the price of the P11pro2021.

Also wondered about the Mi pad5 and the Mi pad5pro and were close to take the plunge on the Mi pad5 when that unit was on early bird-sale at 299Euro - and glad I didnt as that is almost the same price as what you could get the P11pro2021 for at these singles day or BF sale, - and I certainly prefer the keyboard-cover for the Xiaoxinp11pro2021 with the trackpad and the magnetic kickstand where Mi pad5 (and also its Pro version) uses that grove-variant. without any trackpad.

Went for the P11pro2021 and the keyboard (both from Giztop) and the folio-cover from Lenovo Denmark as they had it for around 16 euro with free shipping (seems it comes from England) and that was less. then what I could find it at' from abroad.

btw does any of yours P11pro2021 weigh the claimed 485g.. mine is 492g.

To make it clear, the Samsung Tab 7+ uses a 12.4". E4 AMOLED panel. the Samsung Tab S6 (Samsung 2020 flagship) is the same also an E4 AMOLEDbut in 10.5".

The Xiaoxin P12pro. is 12.6" so a tad bigger than the S7+ panel, but P12pro is also on the old E4 panel, so pretty sure you will get the same results, as the other E4 blue-stripe AMOLED panels found in S6 and S7+.

also why I referred to testing fx an all-red slide on max brightness' when you have both devices P11pro2021 and P12pro, as the E4 AMOLED-grid array's red-subpixels is a tad smaller' than the red subpixels in the Xiaoxin (see the first video in #131), and could be why the red-colors are worse on Samsung's E4 AMOLED panels. (more orange tone)

Samsung is just now finally elevating to a new generation of AMOLED panels (finally).. their so-called E5 generation, but as I wrote above. I don't know if the new Tab S8+ and Tab S8ultra that are about to land in 1q 2022 is with that new generation of E5 AMOLED panels, though it would surprise me if it ain't.

I have had some problems with the charging on my unit.. where it will not charge and just give a message "cant charge right now" and you are quite puzzled.. as it doesn't give any explanation, and you left with a ??.. okay tablet, but when does it then suit you to charge.!!

I hard-rebooted mine, and then it charged fine but precarious experience..

btw..it seems you have been able to take OTA updates without loosing your L1 .. is that the case for others, that are on the P11pro2021 native CN/ENG rom, or have other people lost that L1 widewine by using OTA?

I checked the display for use of DC dimming, and it indeed makes use of DC dimming.

have waveform video on a Micsig ST1104C scope.

Also noted a 144hz bug on the display setting front page (below) though havent installed any OTA updates so far, still, on the OS revision, it arrived with.

I'm quite impressed with the sound-- out of the box. Its 4x JBL-labeled Atmos speakers don't sound good, it gets way better if you activate the "Atmos" feature, but my Samsung's AQK quad speakers still sound a tad better, but If I go into the 10-band Atmos EQ, I can get very close to the AGK Atmos quad-speaker quality from Samsung that IMO is the best on tablets these years. (certainly not bad quad-speakers in the Xiaoxinp11pro2021, but it takes a little work to finetune it in the Atmos 10band EQ)

Also like Lenovo's landscape feature where it flips apps, to landscape-view, quite useful when you use keyboard and trackpad)

Same with the swipe feature, and something I like a lot on Samsung tablets, where you can swipe from the sides, happy to see that on the Xiaoxin. but maybe it is a native feature on Android but quite useful..- same is the feature to jump between current apps you have open, by making a half-circle from below..

The microSD card reader supports up to 1TB, and I tried to test the speed with one of these cheap new Aliexpress Samsung cards-

It seems to max out just under 90MBs read and just under 80MBs write. (128GB Samsung Evo+ white)

also tried with one of the other in Samsung's new line micro SDcard.. the blue Samsung pro 256GB, and it was the same speeds on the Xiaoxin p11pro2021, so it seems to be the max.

IMO the new Samsung Evo+ (white version). more or less same as the old Evo+ (red) and the new Samsung Pro blue, it matches my Sandisk extreme pro when testing on laptops.

Samsung does label this blue Samsung Pro with 160MB read and 120MB write but was not able to get those readings, on a thunderbolt3 TypeC port on Porsche Book with a TypeC 3.0 pr 3.1 SD card reader.. perhaps if I use a USB3.2 reader, though, at around 45USD delivered for 256GB with incl. danish 25%VAT, it's not a bad value these blue Samsung Pro cards with MicroSD card speeds around Sandisk extreme pro.

but the Samsung Evo+ (red or the white version), is still the best bang for the buck MicroSD cards as those you can get at around 15USD.

The cameras are nothing to write home about, it got 4, two in the back and two in the front..but I don't know which CMOS sensors Lenovo is using, but the Lenovo camera app is utter garbage and third-party apps didn't seem to elevate any higher res on video then the 1080p30 that is low (2mpix) for a 13mpix sensor..

So Its a mixed bag, and the overall Lenovo software and the camersa, leave a lot to be desired, but all the other things..gives a flagship vibe, and with the price in mind, its in my view the best bang for the buck Android tablet - in the second half of 2021.

I hope OS13 is being channeled through the OTA channel, at a given point and not only as a manually install..
