It turns out displays on Mi Max 1 & 2 are the same model, so switching the display from Mi Max 2 won't resolve low max brightness problem. As @Zola III pointed out, this issue is resolved in new beta firmware. Hopefully, release version of this updated firmware will be available soon.
Original post:
Code:
Major problem of Mi Max 1 is low display brightness, it is simply not enough on a bright sunny day. Mi Max 2 improves on this - at the price of lower CPU performance, hence the idea to try Mi Max 2 display on Mi Max 1.
The connectors look the same. Dimensions are the same. Camera, light sensor, speaker grille locations are the same; capacitive buttons location differ very slightly, the difference is negligible and they should work fine regardless.
I'd try it myself, especially given very cheap display-digitizer assembly prices - but Mi Max is my only phone at the moment and I rely on it for work heavily, so that's not an option for me until/if it requires repairs.
[B]So, is there by chance a Mi Max 1 user on this forum with broken glass or faulty display adventurous enough to try using Mi Max 2 counterpart?[/B]
I think it's the same display a Tianma display an the most of Max 1, 2 unit's. But you will have to check & particularly to your own one. About max peak brightness on Mi Max well let's say it whose just set as that on up to date firmware releases but yesterday I got an random MiUI 9 Global (still beta) OTA update & on it it's nearly doubled going up to almost 700 nits but you lose contrast heavily when you cross about 350 (73% on old firmwares & about 50% on this one) so it's only good for direct sunlight & battery burning.
Best regards.
@Zola III thank you very much!
Could anyone please kindly confirm the displays are the same between Mi Max 1&2, and the problem lies only in firmware? I figured out how to try new display without disassembling most of the phone, and was about to order. \=
@NCi5 well without firmware side y
You won't get it to be any brighter.
As I told you the display is the same (in most units as I know in some Mi Max ones Xiaomi used & other one which whose worse as there whose a shortage of particular this one)...

@Zola III thank you very much! Hopefully this adjustment will be included in non-beta firmware as well.

First of all, English is not my mother tongue, so I will ask for some leeway.
I have tested the new (well, newest if not new) the Mi 2S (about 1 month) while still having the Mi 2. I wanted to get back to the community in case some were wondering if it was worth a new purchase.
In case, people would ask as to where I bought the phone, I prefer to clear this point at once. My brother in law wanted to buy a Mi 2A for his wife but he only speaks French, so he tried to contact some websites and one held his attention due to some fast replies : www.phonasia.com
I wasn't confident at first knowing some websites where a trust relationship were already built.
Well, since they were using Paypal as a way to pay and he could finalize his payment via phone (they got a French and a UK number) and he got a good price, so...
I had my Mi 2S in his cart and I got it in about 10 days (in Paris, France). Everything went well at the end. For people who would want to buy through this website, I would gladly give my brother in law's email for sponsorship.
Anyway, now this is out of the way, I can begin my In Depth Comparison between the 2 smartphones.
The 2 devices : Xiaomi Mi 2S 32 GB (available since this Spring) and Xiaomi Mi 2 32 GB (available since December 2012).
At first glance, we could say that Xiaomi only changed the SoC (System On Chip), we got the S4 Pro then the S600. Secondly, the Camera got upgraded too, from 8MP to 13 MP (only on the 32 GB version though).
Well, it's not entirely true. Let's go see that.
1) What didn't change
The design of the phone, the vibrator and... that's all. Some photos of the exterior aspect of the two mobiles (we just can't tell the difference) taken from my Canon EOS 350 (a few years old Reflex).
The Mi 2S is on the left here.
More photos here : Dropbox at the bottom of the folder.
2) The Screen
We can't see it cleary on the photos but the difference is quite clear on the naked eye. The Mi 2S' screen is brighter but it's as if it was 2 totally different screens, it's still globally the same screen quality speaking but the difference is there.
Here is the whole screen on screen comparison : Dropbox
The Mi 2S is on the left and the Mi 2 is on the right.
Here is some shots that I selected where I think it would show the difference at its best.
I think the last one with the xda website is the clearer. When you zoom we can see the difference of levels about the white color.
3) Loudspeaker
I don't have yet any device that can measure the sound level (decibels) but it's very easy to tell which one is has the better loudspeaker.
I played a couple of songs while syncing them on both devices and we could clearly hear louder the the Mi 2S.
The downside is that I don't a very good ear, so I couldn't tell which displayed the better sound quality wise.
4) GPS
This is the main change to me. The old Mi 2 (and I tested 3 different ones (my brother in law's, my mother's and mine) had a crappy GPS to say the least. Sometimes it took several minutes, like FIVE which is eternity when you need it. I installed GPS Status, GPS fix but it only worked at first and only sometimes. It wasn't reliable. You can also find some of my posts in the miuiandroid forum in the dedicated topic named "GPS issues" (I think or something like this).
With the Mi 2S, it was like a entire different world, it was like Disney Land. The GPS fixes very quicky like any other smartphone on the market since 2009 - 2010 (my first Android phone was the Motorola Milestone, late 2009 and I never had any GPS issue). Google Maps got a fix and was guiding me within 10 secs. It is really is amazing comparing to what I had before.
5) Benchmarks
Well, I noticed a differential about 10 to 20% in favor of the Mi 2S depending on the used Benchmark. The Mi 2 is displayed on the left and the Mi 2S on the right.
First one : Quadrant Standard
I immediately ruled out that one because of the too great differential which is about 40%. Anyway, here are the results.
Epic Citadel : the difference was nonexistent. I think we got the same results because the GPU is strictly the same, the Adreno 320.
Vellamo : 10 to 20 % better in favor of the Mi 2S.
Vellamo also tests the precision and the latency of the Touchscreen. Let's see the results.
HTML5 test (no idea about the settings despite of the fact that is set on custom)
Next Bench is 3DMark Basic (Mi 2 is above and Mi 2S is below.
Now let's switch 3DMark to Extreme, there is difference of 5%.
Last Bench... Antutu !
The full results (some more details) are available here : Dropbox
6) Battery Life
Well, after 1 month of use, I really can't tell if the battery life is better or not. It seems to be, but it's very hard to tell on the day to day basis since it could seems better because I wanted to believe that and it depends a lot of the usage which is not linear for me. Some days, I would have plenty of work by mid day, the battery would be quite drained and for good reason. Others days, like my days off, I'm hardly touching my phone, and I would have plenty of remaning battery life (about 60%+) to last a second day.
But, I noticed the effect of the new SoC, the S600, the smartphone is not so keen to overheat as the Mi 2 while I'm using it not even intensively but, let's say moderately (emails + Chrome with 10 tabs + Tapatalk + looking at pictures). The Mi 2 isn't overheating but it is warm, at least warm enough to feel it (not hot, not at all, but warm).
7) Photos
Let's turn our interest on the Cameras performance.
Mi 2's shots on the left and Mi 2S on the right. First round of photos in normal mode, second one with HDR. I took the first photos indoor.
(the first shot wasn't set on 8 MP)
The colors taken by the Mi 2S are closer to real life colors. Details wise, I can't really tell the difference yet. The HDR mode on the Mi 2 seems to over saturate the colors a bit.
Anyway, what about outdoors, right ? The shots were taken during a cloudy day, so the lights weren't ideal.
https://lh3.googleusercontent.com/-...0cZzCqQ/s720/IMG_20130610_155745_HDR.jpg[/img
I noticed 2 things :
- the Mi 2S did a better job while lights weren't ideal
- again, oversaturation in HDR mode by the Mi 2. But, overall, in both devices, the HDR made quite a good job. Just look at the sky, we can clearly see the clouds and the sky while in normal mode, everything is "greyish".
2nd day outdoor, cloudy again (it's Paris, what do you expect ?)
These shots were taken with a larger range of colors than before. In normal mode, I can hardly tell that the new camera is an improvement, to me it's quite similar. Maybe someone with more photo experience can tell us more stuff about that.
The downside is that I'm not a photographer and I didn't respect some strict rule while taking photos.
Still, I think the Mi 2S did a better job with the Tree shots.
Let's en this photo shoot by test the cameras in very low lights environment :
The flash is clearly better on the Mi 2S.
The entire photoshoot is available there : Mi 2 Photos and Mi 2S Photos
Some people might draw way better observations than I did.
To conclude this long post :
What didn't change => the global design.
Otherwise, every piece of hardware changed : screen, GPS (!!!), loudspeaker, SoC, Camera and flash.
Overall, the user experience has been quite the same, the Mi 2 is really speedy enough to perform as well as the Mi 2S. But the GPS is a real big improvement to me because I really need it. The other notable advantage, I really felt like the phone isn't getting that warm, at least not as quickly as the Mi 2.
To me, if you got the Mi 2, it's not worth upgrading the Mi 2S unless you're an ultra geek (which I am) and you need the latest stuff out there.
Now, I guess it's time to say good bye and I want to thanks my mom and dad, my family, my friends for supporting me everyday... wait, wait, I think I'm writing, somehow the wrong speech here. I just want to thank you for reading my long post and I hope some of you would have found this one useful enough in their future purchased.
If you have any questions, don't hesitate to ask me here or via PM.
Very thanks for your great comparison/review! i just bought a mi2s, and i want to know how it's the network behaviour overall on this phone? Because one of the reasons to change from my Razr I, it's because i'm having a lot of data drops on HSDPA.... Thanks!
I live in Paris (France), and here, we've got 4 different carriers.
I'm using the one that suits me because I got great coverage at work and home. I can't really tell as to the strenght of the Mi 2S' antenna since my network with my carrier is great regardless the phone.
On the other hand, I have poor coverage with the others carriers, once again, regardless of the used phone.
All I can say is that once you are covered by your carirer and it is well done, then you have next to 0 problem (no data drops on DC HSDPA of stuff like that).
Hi there,
After 3-4 months with my yotaphone 2 I want to share my experiences with it's and other display technologies...
Yotaphone 2 has a very good OLED display. I directly compared it to Samsung Galaxy S4 / S5 and my new Xiaomi Redmi Pro 32GB/3GB version (not to confuse with Xiami Redmi Note 3/4 pro which use IPS LCDs).
S4 / S5 / Yotaphone 2 seem to have the same display panel. Colors and overall image match 99% (they are great). Just the S4 and S5 seem to allow a higher brightness than the yotaphone 2 does. On the other hand yotaphone 2 allows you to go very dark while keeping a good image quality.
Compared to Xiaomi Redmi Pro (chinese OLED) the redmi pro doesn't convince too much. Especially green colors on the redmi pro look somewhat synthetic. Red is OK but not as embracing as on Yotaphone 2. Other colors seem similarily good.
Furthermore (not that much hardware related) yotaphone 2 has a perfect automated brightess control. The best i've seen yet. With S4/S5 and redmi pro I always need to fine-tune in some situations because of auto brightess reacting slowly or brightness going max when not needed.
Maybe someone here or out there on the interwebz cares about comparison of OLED technology displays. They are NOT the same. My opinion:
Most tests / reviews only state that there's LCD and OLED with some of their pros and cons. That's all. But of course there are differences in OLED technologies. Chinese OLED's like that of the redmi pro tend to being not that advanced. They feature sharp image and high resolution but color / black and overall image quality don't match advanced OLEDs like samsung's I would say they reach about 80% of samsung's / yotaphones display quality.
Nice info. Thanks for sharing.
On my side I have to admit that I am deeply impressed with some feautures of my Yotaphone 2, being one the AMOLED display. Although it is not as good as the one I had with my Samsung Note 4, something quite expected, as the other one was one of the top displays with better pixel density and area.
The only complain for the panel might be the maximun brightness that it is also lower to top samsung ones and that the display shows some more reflections that those, making it a little worse on direct sunlight. I also tend to believe that this display tends to be a little more energy conservative than the top Samsung ones, as with a smaller battery, I usually get better screen time than with those Samsung top models (which have a better/bigger screen, but also a bigger battery).
Anyway, it is one of the top displays I've seen.
Best regards,
Hi guys ,
I have two X829 le max 2 two phone both running the Small EUI rom (13.1). One of them has slightly extra brightness than the other.
Is this a hardware or a software issue ??
That's funny, I have two gray 4GB/64GB X829s as well, that I bought from Banggood, and one is quite a bit brighter than the other. Doesn't matter which ROM I use. The whites are also a little warmer on it. It's definitely a difference in the hardware.
May be both phones have different color profiles under color mode ? I might be wrong..
Sharp screen vs truly 2k?
Did you get Aida64 screen info to compare?
Is anyone else having issues with adaptive brightness taking a while to adjust? I am on stock 8.0 with latest security update. When I open the phone it can take 3 seconds or so to apply before I can see the screen.
yes there is a problem, and it is even more irritating for me when in low light room i turn on the screen and it takes 3-4 sec to turn down the brightness
Yes, I have the same issue. Also, my friend has Xiaomi Mi A1 and he also has the same issue. The ambient light sensor responds slowly for some reason. My wife has Redmi Note 4X and its ambient light sensor is much better. Responds instantly when the light changes (e.g. exposing it to direct sunlight). Also, the screen is so much better on the Redmi Note 4X, I couldn't believe. I compared them side by side, and the whites are so white on Redmi Note 4X. On my Xiaomi Mi A1 the white is...yellow, wtf.

Are you sure night light isn't turned on on your phone ?
there are 2 types of screens used in Mi A1, and apparently one of them is showing yellowish colors like you described. the other one is much better and i am really satisfied with color reproduction even with the blacks (not like amoled ofc but really deep).

Of course not. It's just that the display on Redmi Note 4X has better color accuracy. Before I thought Mi A1 has identical hardware as Redmi Note 4X, buy it seems that's not the case.
By now the only thing that annoys me on my Mi A1 is this ambient light sensor being too slow. Apart from that, the phone is OK for the price.

I guess I wasn't the lucky one to get the "right" display.
Ok, after I posted this I turned up the brightness to 50% and still have adaptive switched on, it seems to have sorted it. Previously it was on 5% so maybe there is a bug there that is seeing what brightness setting level it is and adjusting that way and taking too long. Try it and see if it helps (or lower from 50%)

Mi A1 has identical hardware as Mi 5x. And you will be able to adjust the colour of the screen if you root (I'm not sure if it will make it better, because I've got the "right' display, so can't test it)

you can check which display is used in you phone by entering specific code in dialer (i cant remember the code :/), there you can see which components are used, 2 sets of different screens, memories and cameras( not 100% sure for this one) are used.

i always keep it on 50% with the adaptive on and the problem is there..

Did it and the app (Factorykit Test) hangs with a black screen on version info. I think all the other options are fine.
Does it work with the phone rooted with magisk with the stock rom+recovery?
Edit- disabling magisk and xposed solved the issue. The rear modules are OV12A10ii and OV13880ii.

Doesn't work with Xposed. Disable Xposed, reboot, do the tests and enable it again.
As I have had other Xiaomi devices as MI 5 and MI 5s, I´ve noticed backlight buttons on MI Note 2 is pretty low, Anyway to increase it as much as on those devices listed below?

If you could, it would be a setting in a conf file someplace. Or if even possible, do some hardware hacking and change some voltages to get those LEDs a little brighter. Of course actually doing that is more difficult than speculating.
