Full 855 features. - Xiaomi Mi 9 Guides, News, & Discussion

Hi all,
I have been reading the Snapdragon 855 specifications:
https://www.qualcomm.com/products/snapdragon-855-mobile-platform
And I can see there are some interesting features not activated in the MI9.
I am talking about WiFi-6, LTE Cat-20 speed, 4x4 MiMo, CA7, etc.
All of them related to data on air speed.
Some of them need specific hardware (basically antennas) but I wonder if some of them could be activated modifying the Kernel and ROM.
For example, the Galaxy 10 has same 855 processor but has these features activated.
I guess Xiaomi has left some features off thinking on future models.
Thanks

Probably waiting to release an upgraded version of the Mi 9 with 5G capabilities

Not 5G, because MI9 uses X24 Modem, not the newest X50.
Most likely on the MI10
But some other features should be doable to get.

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!

Buying advice

I'm in need of a replacement for my current phone, since it just can't handle modern workloads anymore. Now I noticed this phone on AliExpress and I'm wondering if it's worth buying.
I don't need that much, mostly just being able to run WhatsApp, LinkedIn and a few light apps. Although maybe some multimedia would be nice. I like speed over beauty. And one feature I find pretty much essential is the ability to record my calls.
I notice a whole bunch of different Note 4's on Ali. Two different CPU's, both 8-core and one 10-core variant, 2/3/4G RAM and up to 64G storage capacity. Note 4 and Note 4X. Reading some of the other threads I should go for a SnapDragon, and one can never have enough RAM. But most of those threads are a bit older, maybe the development has opened up more and this changed?
My previous experience with a phone directly from China wasn't the greatest, with battery calibration errors and some apps that just wouldn't install. So I could use some advice here.
Can this phone do what I need it to do (with or without a custom ROM)? Can it be rooted? Which model should I get?
I appreciate any tips and answers you can give me.
Check the following points before buying:
- the 4 / 4X differences are 0, the only important difference is about the chipset
- get the version with Snapdragon chipset, MediaTek is crap
- check the 4G bands available if they're compatible with your country (mainly it's all about band 20)
- choose from the 3GB RAM / 32GB storage version or the 4GB / 64GB
Usually they call 4X the Snapdragon version and 4 the MediaTek one, but this difference is used mainly for identifying the ROMs. Because in reality there are 4X with MediaTek and 4 with Snapdragon. And on the phone box there is written always 4, never 4X.
Then unlock bootloader and install Xiaomi.eu ROM to get all the features you want. It's a lighter and optimized version of stock ROM.
Check if your carrier is using B4 or B20 LTE band. Redmi Note 4 Global support this bands (it's international version of the phone), Redmi Note 4x doesn't support them (it's Asia variant).
Always make sure you buy the variant with Snapdragon 625 chip (Mido).
So that would be a Global Xiaomi Redmi Note 4 with 4/64GiB based on a 8-core Snapdragon S625 CPU?
No surprises? I won't get apps that won't install because they don't recognize the phone? Or a boot loader that's too new to unlock, preventing me from installing a new ROM?
And there are ROMs out there that support call recording?
Looks like the main carriers in NL will support it.
Did I forget anything?
And for the current owners: know of a good flip case or at least something that will keep the scratches off?

Yes you will be fine, just confirm twice before buying that the phone has Snapdragon 625 chip and that it does support B20 band (800MHz), it will guarantee that it is Redmi Note 4 Global variant you absolutely need it since you are from Europe.
Call recording is available even on stock ROM.

which honor 9 model?

Hi. I have a galaxy s8+ which I am thinking of selling to get this phone - mainly because of treble support and the s8+ is too big! I was going to get the 6gb/128gb version which is great value on ali express. I know the Chinese version doesn't have band 20 but that doesn't matter on EE in the UK.
However I wanted to check whether there are other issues with not getting the European version of the honor 9? Does the Chinese version support the new aosp treble based Rom the devs have built? The thread seems vague on this issue. Other there any other issues with the Chinese version?
Appreciate your help.
As far as i'm aware, you can actually re brand the Chinese variant to EU.
Not sure if the version of android on it has Google Play services, or an English language selection, but language packs can be downloaded.
BUT! you will get the OS updates before us lot with EU versions.... who are still stuck on B182, China have got B360 which is oreo.
Either way, its a good buy, destroys the s8 in benchmarks, and just the right size to not be too small or too big in the hand.
There 3 differents STF Chinese honor 9:
AL00
AL10
TL10
I've got an AL00 rebranded to L09 and it's working great, like an European model but without LTE BANDS 7(2600) & 20(800).
Thanks for the responses. I thought the Chinese variants of the honor 9 were the same as Xiaomi - only missing band 20? I'm on EE which doesn't need band 20 but I believe does need 2600mhz (band 7). Any ideas? Thanks
https://m.gsmarena.com/compare.php3?idPhone1=8704&idPhone2=8704#europe,al00
You could change phone version on this link, I think LTE BANDS are corrects but there is errors on size and colors.
Thanks. EE state that most of their 4g coverage is with band 3 so should be Ok! Thanks for the responses guys.
I wouldn't expect huawei to use a different LTE chip in each phone, that would require 2 different versions of the kirin 960, which wouldn't be in the interests of the development cost of the phone.
I'd assume its an OS limitation, since AL10/100 firmwares will run on L09 models after rebranding, and vice-versa.

I'd like it to be true.
Do baseband is inside Kirin 960 cpu chip or in another chip?
The way I see it they ship differents variations with differents nand & ram sizes, so maybe they could switch others things without adding tremendous producing cost.
Or they are the same but phoned still keep their original LTE bands over the publicly available rebranding guides.

QUESTION FOR ANY USERS with International Galaxy Note 8 (SM-N950F or SM-N950F/DS)

My note 4 got broken and I am considering an either a Note 8 (or Note 9) to upgrade too. My dilemma is between having a fully unlocked boot-loader (I like custom roms etc) and all the customization that affords VS the US Notes that are boot-loader locked and have limited ROM support (if they even do) BUT have Zero Issues with Carrier aggregation.
So my question is...to those of you that have the international versions that don't do proper carrier Aggregation (yes I read the 50+ page thread and a few other threads as well)...and may have limited speeds and not stay connected as well in fringe areas as the US version....if you had it to do again would you buy the international one again for the modding ability or is/was the trade off of the carrier aggregation too problematic?
SM-N950F and SM-N950F/DS are Exynos-versions so these doesn't support well Carrier Aggregation combinations used in US. I don't have data from Note 8 but i have many other devices listed in cacombos.com. Exynos devices modem can't be edited like Qualcomm devices.
Thank you Olkitu, I ended up going with the snapdragon one, but I did bookmark your site for future reference as my wife's phone will be needing replaced in the next few months as well.

BE2026 - Dual Band Galileo?

Anyone able to verify if the BE2026 only supports single frequency Galileo or does it actually receive both E1 & E5A?
Oneplus’s specs state dual frequency GPS while not specifically calling out if Galileo is dual frequency.
What is worrying is that specs for the Oneplus 8’s and the 7T do list support for both frequency bands.
Been looking for a moderately priced Android phone that supports GPS and Galileo dual frequency reception for outdoor activities.
Well, after some further research, it appears that it does....(provided there is isn’t some weird hardware omission between the various models)

Be nice to have an Android device again after a few years of iOS. Excited to see what has changed.
