Yes, that's the vibe I'm getting out of the images.
[Android Q&A, Help & Troubleshooting] nr-thunder:
I researched a lot about this device and bought it (still in transit). I used my browser and google lens a lot for the active russian 4pda qin 2 forum, it works well enough for tech talk. Youtube translations for russian video reviews are also not that bad, it has errors but you get the gist. Most of info available about this device is in chinese or russian.

So here is some stuff:

Official Youpin links: Qin 2 / Qin 2 Pro

SOC: Qin 2 = Unisoc SC9832E (28nm Quad-Core) + 1 GB RAM / Qin 2 Pro = Unisoc SC9863A (28nm Octa-Core) + 2 GB RAM.

ROM: Qin 2 chinese = customized Android 9 GO (app installation limit, no GApps, vertical recent tabs, fullscreen gestures). Qin 2 Global = Android 9 GO (GApps, totally vanilla)

Qin 2 Pro Global = Android 9 (GApps, vanilla, not GO)

Camera: Qin 2 = 5MP; Qin 2 Pro 32GB = 8 MP (Software limitation, actually 13 MP); Qin 2 Pro 64GB = 13 MP

2 IMEI: The Qin 2 (Pro) has 2 IMEI numbers, but all available variants are single sim only. They discussed about that a lot at 4pda, and it's impossible to get it to work. It's a single-sim device + a "digital sim". The digital sim is NOT an E-SIM as we know it, which would still have physical hardware needed to be present. Long story short, it's not unlockable with software.

BANDS (from official youpin store. No differences between Pro/Non-Pro/Global/Chinese/Whatever):

2G GSM: 2/3/5/8

3G WCDMA: 1/2/5/8

4G FDD: 1/3/5/7/8

4G TDD: 34/38/39/40/41 (listed at Qin 2 page, but not at Qin 2 Pro, so I suppose they just forgot)

Charging Pins: For this charger https://www.banggood.com/Qin-Univer...-2-Pro-p-1649196.html?ID=224&cur_warehouse=CN

Colours: Qin 2 (black/white/blue/red/pink); Qin 2 Pro (black/white)

Custom Rom/Modding: Overall there don't seem to be any hardware differences between the chinese/global variant.

Still I haven't seen anybody flash a global image, just unlocking GApps and bypassing the installation limit. Also somebody installed a Android 10 GSI (generic system image), but something about rom validation makes the process more difficult than for other devices.

Where to buy?: https://www.banggood.com/QIN-2-Pro-...483.html?rmmds=search&ID=224&cur_warehouse=CN

Prices are okay(135€, at youpin store it would be about 100€, but without the customs free delivery). It's not currently available for cheap at aliexpress, and buying there has the risk of paying custom fees.

Which one to buy?: Qin 2 Pro Global. The 30-40€ less on the import price for the normal Qin 2 are not worth it to skip out on better SOC/RAM/Memory/Camera. It's not worth it to buy the chinese variant just for the vertical recent tabs or the gesture navigation.

EDITS: Edited wrong information thanks to kiora.

System:

Qin2 -> Android 9 go

Qin2Pro -> Android 9

Camera:

Qin2 -> 5MP

Qin2Pro ->

2+32 8MP ( limited by the system )

2+64 13MP ( The physical lens is exactly the same as the 2+32 version )

The release of the global version of Qin2 was a leak. For some reason, the global version of Qin2Pro will not be released at this time.( I have posted screenshots on chiphell ) Of course, this does not restrict you from extracting from your phone after purchase.

In fact, the power consumption of the global version is not ideal. I personally recommend using my GApps- version firmware for those who need to use the Google program.

I think that when you read Global Version , the seller flash the firmware from Android Go to Android Stock but it is my vibe...if so you can ask to leave the chinese firmware
[Android Q&A, Help & Troubleshooting] ppczouz:
Good idea. I contacted the seller, but they wouldn't do it as they offer 2 versions: the global and the Chinese, and they have already shipped the phone earlier that day anyway. So I'm getting the Global it seems.

So I will look into a way to flash back the Chinese rom + gapps

Btw, has anyone extracted the launcher they use on the Chinese version? it looked quite optimized for the extra tall and narrow display.

[MENTION=3335874]kiora[/MENTION] Can you please link the file + instructions (is it the 1.1.3 from Sillage with GApps)? And is the battery life notably better? (I guess there is a huge difference in standby drain between android 9 and Go)

Does it have root + removed app limit?

I will probably test the installed rom first, as their seems to be some issues with the Chinese+GApps rom on 4pda.

1. Version 1.1.3 has an official Chinese version and a modified version that includes GApps.

2. The files for chh and 4pda are the same.

3. For some reason, the public link has been deleted. Please send me a message at xda or chh or 4pda.

[Android Q&A, Help & Troubleshooting] ppczouz:
After a *long* (LOOOONNNNG) wait, I finally got the Qin2 Pro 64GB

It is absolutely awesome for what it is. It has the Global ROM (Android 9, March 2019).

For those wondering how that affects battery life, I believe it doesn't as I am experiencing awesome battery life with the all the caveat of a typical xiaomi ROM (overly aggressive in killing apps, what before you hit the 2GB Ram limit)

One observation and an extreme disappointment: Everywhere I read, it said it has dual band Wifi, but that is not the case. Only 2.4Ghz Wifi is supported.

Camera is 13MP, but quality so far has been so terrible that I trained myself to assume it doesn't exist: focus hunts but locks on an invisible ghost that is always standing between you and the subject of your picture.

I have installed Smart Keyboard Pro as it offers a full keyboard, a Compact Keyboard (blackberry half-qwerty predictive keyboard) and a T9 keyboard. switch simply by swiping up on keyboard. pretty awesome.

For Launcher, I would really love to have the Qin2 Launcher, but for now, I am using the Launcher 10 which is awesome for tall screens (after little customization). Here are some screen shots:

Anyone can share the Qin2 launcher? all links I found so far to download it are broken.
[Android Q&A, Help & Troubleshooting] ppczouz:
BTW, the global rom does not support gesture navigation, which is a major bummer.

I use FNG (Fluid Navigation) which, after granting it permission through ADB, can hide/show the nav bar. Pretty effective except it keeps losing the Accessibility permission for some reason... which makes it inoperable until the permission is re-granted. fiddling with the battery optimization mitigates this to some extent, but it still is happening occasionally. If you know a fix, please shoot it my way.

Global firmware is owned by Ali Seller, but has not been released.

Nevertheless

If you want to install something similar to the global firmware,

There is a way to unlock your device's bootloader and install the aosp ROM.

The problem is that the global firmware is also more unstable than the Chinese firmware, and the aosp ROM is more likely to do so.

---------- Post added at 03:12 AM ---------- Previous post was at 03:06 AM ----------

Global firmware sometimes causes notification suspension issues.

There are two solutions.

One is a moderate solution, by entering the app's notification settings and turning off apps that don't need notifications. If you turn on only important apps, the notification stops occurring less.

Another is a radical solution. When replacing with Chinese firmware, the problem of stopping notification is rare. However, it is not possible to return to the global firmware at this time.
[Android Q&A, Help & Troubleshooting] Ulcade:
Thank you very much I'll try the moderate solution first:good:.

In case I need to replace the global with the chinese, is this guide the one I need to follow? (I cannot post link, i'm referring to "how to install stock firmware on xiaomi qin 2" from a site called "romprovider"

[Android Q&A, Help & Troubleshooting] yamabokra1:
is the gesture working?
[Android Q&A, Help & Troubleshooting] ppczouz:
No, the global image dues not have that option. I have installed FNG and granted it access via ADB to hide the NAV bar and implement gestures. It works flawlessly.
[Android Q&A, Help & Troubleshooting] yamabokra1:
I used it but it closed when ever screen is off.
[Android Q&A, Help & Troubleshooting] ppczouz:
It used to close and lose the "accessibility" settings that allows to run over apps, but I did 2 things to prevent it:

1. Disabled battery optimization for FNG

2. Allowed it to access notifications (that is essential to keep it alive, it keeps posting a notification for itself then removing it automatically).

I have the Pro version with 2GB RAM, btw.

---------- Post added at 03:56 PM ---------- Previous post was at 03:40 PM ----------

Observation about battery life and memory:

I was using Launcher 10 and Microsoft Edge browser.

Worked very well, but it annoyed me how apps kept closing while going to background, especially MS Teams and Duo.

Then I switched back to Chrome, that made a good difference. Chrome services are running anyway, so Edge was an additional burden.

Uninstalling Launcher 10 and going back to default launcher (called Quick Step) freed up more memory and made the device snappier.

But I still experienced the closure of all apps (but FNG is never killed at this point and made life so much happier with the phone)

Last was the Qin Launcher replacing the default launcher... OMG what a difference. Now Teams stays alive, and battery (which has always been great) is slightly better. I'm getting about 2.5~3 days of light use with always connected and receiving replicated notifications from my main phone. (I use the Qin as a glorified Smart Watch ? mostly)

Also, even with Teams running in the background, I have about 850MB of free RAM. That's nearly half the memory.

I'm really liking this little wonder now.

I really hope there will be a Qin3 with much of the same DNA. All I would look for is a front camera (put in the chin if you must), a 4GB RAM, and a slightly faster and more efficient CPU, maybe something like SD450 or Helio P23. And why not make my day with an SD665 or Helio P60 ?

Xiaomi qin 2 Pro

A greeting to all, I read a little bit the discussions on this post and if I understand correctly you can not install the global version on the xiaomi qin 2 pro.

Just today I got the xiaomi qin 2 pro in Chinese version, I am Italian, and I need to install the global version.

I was wondering if someone managed to install the global version with the gapps to post links where you can read a step by step guide for flashing the smartphone. I found a guide to install twrp place the link here. www\androidweblog.com/xiaomi-qin-2-pro-root-twrp-recovery/

What do you think about it? Thanks to all
[Android Q&A, Help & Troubleshooting] Hampa_D:
personally, and I've been using the "global" version for a week, I'd stay away from the "global" it's way to aggressive with battery management even if you give all the necessary permissions. sure it could be a language thing, you might need it to be in Italian, I get it. but i strongly doubt it's worth it in the end :/

I'm still hoping that someone replies to my previous post on how to change from global to the chi/eng silage fw in hope to make the phone more stable....
[Android Q&A, Help & Troubleshooting] EnricoNaples:
so if I understand correctly you want to switch from global to Chinese because it is less stable than battery right?

Beautiful phone

Congrats on getting your phone.

I have mine for a little while now and I absolutely love it.

I too had suffered from the aggressive battery manager closing everything and delaying notifications. But I found 2 things to be helpful (a bit):

1- install the original QIN Launcher. that will save you tons of processing power and will free up memory compared to the google stock launcher

2- Do not remove app optimization, instead, keep the main option and select No Optimize on the sub options.

Also, do not introduce new apps if you can use the built it in: example use gmail for email (it is always running and won't be put to sleep). Same for calendar, notes (keep), and Chrome and so on.

I, like you, am waiting for a way to switch back to chinese ROM with a way to install gapps. That would be ideal for me.

Hi,

I went over this entire discussion (all 9 pages) as I'm interested in buying this phone (I think I'll get the QIN 2 Pro).

I have a few questions:

1. How did you install the original QIN launcher on the Global version?

2. Do you know if I can manually remove some of the G apps? I want to have Gmail, Maps, Calendar, Keep, Waze (if possible).

3. I don't mind getting the Youpin QIN 2 Pro - Android GO (2G RAM + 64GB) and having the OS in English as long as I can install the apps I mentioned in section 2 and having the option to add a Hebrew keyboard. Do you know if one to these is possible?

4. Can I install the 6/12 applications using APK? I don't really need more than 12 apps for my usage (I'm currently using Nokia 208 LOL).

Hi,

I recently got my Qin 2 Pro Global from here.

I read trough this whole thread and also some parts of the 4pda thread for this device.

Since rooting and installing TWRP seemed a lot more complicated than with other devices and I could not find a stock firmware image anywhere I decided to backup my own stock firmware with the ResearchDownload tool (to unlock the bootloader one even needs a working image).

I followed this tutorial and used the pac file (Ver1.1.8) for the Qin 2 Pro (non-global) provided by the 4pda user Sillage as base.

Unfortunately now my phone is stuck on boot logo. So the thing I wanted to prevent happened instead 😅. The device is soft-bricked.

One thing I noticed is: The background color of the boot logo changed from blue to black. It seems Sillage included a custom version in his pac file. And since the tutorial told me to tick the boot logo line the original one got replaced.

I have three guesses what happened:

The locked bootloader does not like changes to the boot logo.

On the Qin 2 Pro Global the boot logo partition is also getting verified by vbmeta. Hence Android Verified Boot fails.

The used base pac file from the non-global version is not compatible with the global version and because of that something went wrong during backup.

I tried to check the contents of my backed up vbmeta_COM3.img with the command @PeterCxy mentioned in his first blog post: avbtool info_image

But unfortunately the file is unreadable: Given image does not look like a vbmeta image.

This is my first time using ResearchDownload. So I am not sure if I need to first convert the backed up files before using or if the backup simply failed (no error during backup).

The only idea I had left was to again look for a copy of the stock firmware and flash that. The 4pda user Sillage does not provide a firmware for the global version (anymore). And the only mention of my model number (s9863a1h10_Natv) I found elsewhere was an user upload in the Infinity-Box forum. Unfortunately one needs to own a Infinity-Box hardware dongle to be granted access to their user uploads. And even if I somehow could get this file, I am not sure if I could simply flash it with ResearchDownload.

So I have now a Qin 2 Pro Global stuck on boot logo with a locked bootloader and a backup I can not use.

Is there anyone who can help me with this?

Hi mate, hi to everyone,

This is my first post.

I'm from Spain, so I'm very sorry in advance about my english since it isn't my mother language.

I got the Qin 2 Pro 64/2.

I really love the form factor, the compact size and so, but this phone is driving me crazy; due to the uncommon soc and particular idiosyncrasy, is difficult as hell to get it rooted and unlocked, and even more difficult get the official rom in PAC file.

Finally I got all the necessary files, tutorials and scripts to do anything, thanks to 4PDA forum.

The problem for me is I'm a completely noob with Linux code and I'm not be able to work it out.

If you don't mind, I'll pm you later and try to help you out with the rom or whatever you need.

By the way, hope this is a correct form to introduce myself...
[Android Q&A, Help & Troubleshooting] PeterBurner:
Hi @Puntieris,

thanks for the offer. I am extremely careful right now. I don't want to break the device more than it already is ^^.

As far as I can tell the 4pda thread only contains pac files for the non-global version of the Qin 2 Pro 64/2. Since I bricked my phone (Qin 2 Pro 64/2 Global) while using a non-global pac file I suspect that global and non-global are not compatible.

If you have an official pac file for the global version or if someone here could confirm that I can flash the non-global firmware provided by Sillage while having a locked bootloader, that would be very helpful.
[Android Q&A, Help & Troubleshooting] PeterBurner:
Quick update:

I did some more digging at 4pda and found a comment that confirmed that the global and the non-global firmware are not compatible indeed.

I should not have used the non-global pac file for my backup in the first place.

This also explains why I could not open the vbmeta image with avbtool. The backed up images are all corrupted 😞.

Another thing I found out is that there is no publicly available pac file for the global firmware. Apparently 4pda user Sillage has one but does not want to share it.

So the only thing I could do now was flash the complete Chinese firmware.

Fortunately it worked.

After that I was able to unlock the bootloader and flash AOSP.

Happy end 🎉
