note 4 and note 4x - Xiaomi Redmi Note 4 Questions & Answers

Hey guys I saw to threads that have almost the same questions and answers that I am looking for but it's not being specific....
My question is if I was to buy right now Qualcomm 4gb 64gb note 4 will the 4x (mido) ROMs work on it?

Yes

Buy Redmi Note 4 Global (Snap 625) if you need B20 LTE Band. If you dont need it you can get 4x.
And yes, Snapdragon 625 SoC = Mido , Mediatek SoC = Nikel

Redmi note 3 different versions

Hi,
I wanna order my redmi note 3 but i don't know what phone is the right one. there are so many models...
i want to flash a pretty clean AOSP or CM rom on it that is stable so im required to buy the right model.
When i look around i usually see pro's, with 3GB ram and a octa core but i have seen some with hexa core both claiming to be snapdragons...
I want to use this phone in europe.
which one is the Kenzo model with snapdragon and alot of custom roms etc?
are there a lot of 'fake' xiaomi's on ebay?

You get the snapdragon. It is a hexacore SD 650.
What LTE bands do you need? There is a Kate which has more than the Kenzo.

I think B20, will probably not get 4G unless in bigger city's but i don't care for 4G that much anyway.. 3G is fine by me.
Doesn't kate have less rom choice?
Which is better kate or kenzo? and how do i know which one am buying??
Kate is newer than Kenzo, so yeah it has less support and even some people don't know it exists!
Kenzo is the Redmi note 3 Pro. Has LTE band 3 (1800mhz) only.
Kate is the Redmi note 3 Pro special edition or international edition. Has LTE Band 3 and Band 20 (800mhz).
I ordered the Kate one although I know it has less support, but I need all international LTE bands!

At least Lineage 14.1 and AICP are, don't know about the others.

I think the only differences between the two are in design.
top: IR/Mic location.
bottom: 5 speaker/Mic holes in N4X / 6 holes in RN4, and the two screws on RN4.
Both devices are (mido)
RN4x have more bands...
RN4 SD LTE bands 3(1800), 5(850), 40(2300)
RN4x LTE bands 1(2100), 3(1800), 5(850), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500).
and bluetooth i think on RN4 SD is 4.1 and in the RN4x is 4.2, only that.
the Xiaomi Note 4X have louder speaker but the plastic at the bottom and the top make it feel cheaper since the original Note 4 was full metal/aluminium...

Difference between Note 4 SD 625 and Note 4X

So the Note 4 625 is cheaper on Aliexpress (global version with bands) than the 4X. Now I wonder if the SD 625 version has the display and camera of the X20 version...
What are the differences and can anyone confirm if they are the same or different?

I already write about these differences - you can find it on my post here: https://forum.xda-developers.com/showpost.php?p=71608109&postcount=7
Note 4 (MTK) has Samsung S5K3L8 camera sensor - Note 4X and Note 4 (SD625) have Sony IMX258 camera sensor
The global version will let you have 4G in some countries that wouldn't work in 4G cuz it lack of the neccesary band (the 4x version)
I think that's the main difference? other than that it is the same as the 4X and the Note 4 with Helios X20 is the oldest one but still kicking ass.
Edit: Summary!
Note 4 Helios x20 has some great performace but it is less efficient and the battery will drain faster than the other versions
Note 4x Was made for the Indian using a snapdragon 625 cuz xiaomi can not sell mediatek anymore in india i do not remember why; The snapdragon has a much newer architecture and is more efficient with the battery consumption so you will have more time of SOT (Screen on Time)
Note 4 Global Same as 4x but enables 4g connectivity in some countries that needed that band, the 4X runs in 3G or H +

Dude Note 4 is the Indian version, not 4X

Why Wi-Fi 802.11AC doesn't work on Redmi Note 4/4x (SD625) ?

Im fairly sure Snapdragon 625 supports it, so why it doesn't work?
Can this be enabled in custom ROM's?

I noticed this today as well. Really surprised. I'm connected to 5Ghz 802.11n no problem though. I wonder if it's possible to inject blobs from another SD625 device and unlock 802.11ac.
Edit: Did some quick research. The Asus Zenfone 3, Samsung Galaxy C7, Lenovo P2 and Oppo R9S all have the SD625 and have 802.11ac, but the Huawei Nova, Moto Z Play and Moto G5 Plus also have the SD625 but only 802.11n. Weird. Our Redmi Note 4X can definitely use dual band though, so the antenna is there.
Yup, probably cost cutting by Xiaomi. (like Qualcomm Quick Charge)
Is there an answer to the AC question? Can it be unlocked by software, or is AC disabled in hardware on the redmi note 4 snapdragon?

I would like to know the answer as well, especially for Redmi 4X.

LTE Bands in Indian Redmi Note 4(SD)

Redmi Note 4x and Redmi Note 4 (SD) Indian Variant both Share Same Device Codename (Mido), Same SoC and same Kernel Source. But Indian Redmi Note 4 (SD), Don't support LTE bands that is being Supported by Redmi Note 4x(Global).
So, thing is, Can We flash Redmi Note 4x Baseband Firmware for Support of All LTE bands, as I don't think, XIAOMI will give update for 2100mhz Band LTE Support in Indian Redmi Note 4 (SD) one, so We are left with own Testing and modding.
I want someone to shed some light over this, is it possible and if someone Can Guide, or test.?
TIA
Short answer: No. It is not possible
OK. Lemme prove Wrong..?
Take a look in other threads and you'll see everyone who has tried have all failed
Hi,it's possible for 2100Mhz(with WCDMA radiofront),I had some posts on MIUI fourm deleted,perhaps the administrator of MIUI fourm doesn't happy to see you guys unlock the 2100Mhz band and nobody willing to test it,maybe the extra patent fees ?
