Face unlock

Just got Mi 8 (global version) and can't see any options for face unlock? Thought this thing had dedicated stuff for it in the notch? The first update it did there was referred to adding face lock to France etc, perhaps coming in an update ,is it? Ta (UK)

Come on... Did you google for this problem? Change region of your device to for eg. India then you will get it. Only some regions got face unlock yet. Or you have to flash Xiaomi.eu rom, which I think has enabled face unlock for all regions

I came on and googled. Changing to Hong Kong region enabled face data option in lock screen an passwords. Some say India enables for them. Some say doing this affects GPS but tested and seems fine using GPS test up to 4 meters accuracy in the UK. Cheers.

Got the same issue here, was happy for a while running the Indian region, but it stops my mobile hotspot working which I need for work! Another issue I'm interested to see if you have is that Google assistant unlock features are greyed out, ie OK google doesn't unlock the phone and is not recognised unless search is open.
Is there any way of flashing to EU ROM from Official Global without voiding the extra support to keep everything official.

Unfortunately yes it is possible to do. There's plenty of tutorials for work arounds on how to clear the email linked to the device. I'm not 100% sure if this has changed in pie, but it was certainly possible before that. I hope you manage to retrieve your phone

thanks

so any good reason to invest another 800 usd or so on the next phone?
i mean are there any that provide a decent security against someone just wiping it new :/ ?

First of all that sucks, sorry to hear that.
Second, if there is proper regulation in your country then reporting the IMEI to any operator should make the device useless in your country (it will not connect to a cellular network).

thanks

it seems that is the only choice so far , it just sucks that android doesn't require a password to switch the phone off when locked that would've at least given me time to track the phone with the authorities until the battery went down.

Regional Lock

Hi There
Hopefully some insight can be shed on this topic, it would be greatly appreciated.
I've read that all you need to do is use the device in the region of purchase for 5-10 mins of local calls & then the region lock is unlocked to any world wide sim.
- is this still the case with Samsung devices?
- lets say once the device is unlocked (in country of origin) but reset a few months later in another country other than it was bought in, will the region lock be back?
Thanks

so, the question youre asking can be answered in several ways. Firstly, the locks placed on the phones are placed by the carrier, so if your phone is truly unlocked, itll never lock on to a service provider permanently. The process you describe about using it for local calls for a few min to have it grab your carrier is CSC related and more applies to whether you can use SPay and SHealth or not. There are also subsidy locks that make carrier switching impossible without an unlock. These subsidy locks can be in the firmware or even an app that was granted root permissions making it impossible to remove on snapdragon devices outside of Odin.
I guess, what issues are you trying to avoid?

Firstly thanks for taking the time to respond. ?
So I'm not technical at these things but here's a quick background on my query.
A friend purchased a Samsung from an Asian country now while there & the box said specifically that it is made for use in that region and their sim. He's using it but won't know if it will work here till he returns. He is able to get one for me as it's much cheaper there, hence the research on the topic.
Through my search I've seen on Samsung forums people buying phones from difference regions with some able to successfully use it in their country & others not (comments vary on reasoning as to why but the use of that country local SIM seems common)
When he queried the sticker they said to just follow that calling process (I'm presuming now this is the carrier lock) However I'm not sure if there are carrier locks on the device as through my search, that country normally doesn't practice carrier locks (Service Provider) as the US or Europe does as devices are sold at any shop in Asia. So it's a bit confusing..
From your knowledge, let's say he activates & uses it for a few minutes. When he returns & I reset the device, will the lock revert back for that region or will be opened for any sim? And something that just came to mind, as the Samsung devices are regional, will this affect how updates come through or will it be based on that regional timetable for updates?
Thanks again

terrible questions.. i tell ya what..... TOTALLY KIDDING!!
actually very solid questions and its also great to hear people doing this kind of research prior to pulling the trigger. I commend you
Anywho, lets see.
1: What Asian country? Yes, it matters. Or if you can get the model number from the download mode screen, that would be helpful too. If you dont know how to get to the DL mode, power the phone off, hold down the volume down button along with power and itll boot to a warning screen that will say volume up to continue to download mode or volume down to reboot normally. If you cant get that kind of access to the phone (or your friend rather) then its a crap shoot as many phones being offered up like this have been found to be non-us versions or even worse, utter fakes. Buyer beware if you cant get to download mode to at least check that too. Download mode is the hardest part to fake, fwiw
2: Galaxy S devices come in 2 flavors, Snapdragon and Exynos. Well, 3 i guess, the 3rd being fake. Snapdragons are the only ones that can work on CDMA carriers such as Sprint and VZW, Exynos phones work on GSM only. SD phones can also use GSM services, but the Exynos equipped phones are GSM only. SD are not rootable, Exynos are.
3: The part about your friend using it with their SIM and having problems strictly due to that. No. So long as its a legit USA model with no financial locks on it etc etc, you will be just fine. You might have to flash a CSC file in download mode or perhaps even the entire firmware (doubt youd need to do that last part), but if its an unlocked SnapDragon model built for the US market, then youre good to go.
4: make sure it doesnt have a FRP lock enabled. As long as your friend can boot it up and get past the login screen, you should be fine.
5: The last bit about the SIM again, as long as its a legit G973U with no locks and FRP inst on, you should be good to use it on any USA carrier no matter where it was initially used.
6: updates are issues out in order of IMEI batches. Being physically in a country outside of the one that the firmware is for can and often does impede updates, but thats not a worry as updates can be easily flashed manually and once the phone is on the correct CSC and physically in the right country, then updates will go on as normal.
7: youre welcome

Firstly apologies for the long delay in response, just been crazily busy and was doing research on what you said soon I am up to scratch to what you said.
1. It is from India, and yes I am aware of fakes so any purchases will be from reputable seller's. I'll have to do some research on that because I'm sure the different Samsung models will have their own codes.
2. I believe for that region they get Exynos variants.
3. From looking at some of the Samsung models online I see the product code ends with "INS" which I'm pretty sure relates to India and that country only so probably I will have to follow the DL mode you explained for my region in changing the CSC
4. I never knew about this.. How does one make sure its not enabled? Is this in the process that relates to no.3 during the CSC change?
5. Not from the US but good to know lol
6. Perfect lol
7. Thanks again, appreciate it :good::good:

2. I believe for that region they get Exynos variants. i believe so too. Id just get pretty much any F variant of the phone model you want and youll likely be able to get it working from there
3. From looking at some of the Samsung models online I see the product code ends with "INS" which I'm pretty sure relates to India and that country only so probably I will have to follow the DL mode you explained for my region in changing the CSC. just stick with the F models, you can flash whatever carrier stuff you need after you have it in hand
4. I never knew about this.. How does one make sure its not enabled? Is this in the process that relates to no.3 during the CSC change? Itll show you this in the download mode screen. Itll say FRP: on or FRP: OFF
5. Not from the US but good to know lol

SIM registration issues - hardware or software

Hi, I recently replaced a non functioning 9T Pro mainboard with a replacement which is working well in all aspects except SIM registration (the main phone function ...!) - looking through the details it looks like it's a K20 Pro from India (from Alibaba, origin not advertised) and the ROM is Indian. The SIM doesn't seem to be able to register on an Irish network. My question is whether the radio restriction is a hardware issue or is software fixable - I'd be grateful for some advice before trying to unlock the bootloader install an EU ROM, as it's difficult to get the unlock from Xiaomi without a functioning SIM for SMS OTC etc. I've tested the SIM in other phones and it registers on the network okay. I've also tried a different (known working) SIM in the problem phone, without success, which is leading me to think the issue is isolated to the phone rather than a SIM issue. It would be really helpful if I could find out whether going dow the flashing route it worthwhile or a dead-end. I've spent many hours flashing various phones over the years, trying to match ROMs etc., and know what a rabbit-hole it can be.

Hi, any takers on this query ;-) - I'd love to hear from any tinkerers who could give me a steer on whether I'm wasting my time going down the unlock / flash with correct regional variant, or if I should just write off the board / phone as being only useful for wifi rather than sim network. If someone who has treaded this path before with some success could let me know I'd be much more enthusiastic about dropping a few hours on it - I've spent many hours on flashing various devices before, and usually have less hair to show for it before I'm successful. Even if it means (as I've read in a few posts around here) that if I lock the device again on a rom that's not regionally compatible I'd be inheriting a paperweight(!), it would be nice to know that in a controlled environment the sim would work. Would be a shame really to nothing with the board as I (stupidly!) splashed out on a 8GB 256GB replacement and (surprisingly) any queries to the vendor on AliExpress have fallen on deaf ears surprisingly ...

Unlocking Bootloader usually requires to wait 7 days and during that time phone must have a proper SIM card, attched to the Mobile network.
Not sure how would you do that in your case?!
Anyway, start waiting for those 7 days, better earlier than later. If you change your mind, you simply don't unlock the Bootloader upon the 7 days of waiting pass

Yes, good idea, thanks for the suggestion. I'll see if I can kick that off / whether the sim registration issue blocks me. If anyone else has been able to verify that flashing can help regional issue with SIM registration and support bands that would be great too! Thanks.

Question Xiaomi 11t Pro VoLTE and Vowifi

HI Guys,
I just bought this phone for sure I love it but I live in an area where VoLTE is and VoWifi is a must to have due to poor mobile reception
I used the dial in numbers to get VoLte and and Vowifi activated got success and was able to switch them on from Mobile network menu, but they aren't working at all I tried with flight mode on and off for Vowifi same thing, tried sim card from another network no use, and signs for VoLTE or Vowifi hasn't come on notification panel also
I am on Global Rom
MIUI Version 12.5.10 (RKDMIXM)
Does anyone knows any solution to this
Thanks in advance

I've had a problem with my carrier and Wi-Fi calling which I had to fix myself. Xiaomi do nothing except bundle the default carrier settings and very little testing is done if any. There is a good chance the carrier configuration settings for your carrier are missing or broken.
If you can let me know the carrier and country you are trying to get it to work with I will take a look at the modem configuration settings for that carrier and see if it has anything in it for VoWiFi or VoLTE.
Getting it fixed however, unless you go down the technical route of using Qualcomm debug tools and unlocking the bootloader and rooting, the chances of getting it fixed is close to zero. Xiaomi have never looked at the bug report I filed months ago.

HI Philip,
Thank you for the response I am in Australia using Telstra network, I tried Optus Sim as well having the same issue with it, the only solution I could find is in below link
https://forums.whirlpool.net.au/archive/3rppj4r3
It says have to enter into Modem test tools to change region and network to Australia which isn't possible without unlocking the bootloader, I have requested bootloader unlock permission if it doesn't help will need to switch the phone

I've looked at the modem configuration file relating to IWLAN and the settings are there. It is noted a Certificate is required to join the IWLAN for VoWiFi so it is possible that certificate isn't on the phone or is now out of date so a connection isn't allowed. It is also possible other configuration settings in the config file are out of date and need updating. If it is possible to get another carrier modem file to work, then often other things can break, but at least that would give a pointer to what changes need to be made by comparing the two.
It should be noted that Xiaomi don't really test these devices everywhere and they seem to just use the default Qualcomm provided carrier modem files and hope for the best in any particular country. You can use the feedback options to tell them of a problem but in my experience you will never get a response and in my case they've never opened a linked file with extra information (on Google drive so I can see who last opened it).
Regarding the other forum info, well I've not been able to get the modem test tool working on the 11T Pro (says to contact the modem team for permission), and the forum posts suggest we need weekly test ROMs where the permissions are enabled, however there are no weekly ROMs for the 11T Pro as far as I know. The next best thing is to modify the same settings using the Qualcomm debug tools, this takes some effort to get working.

Thanks for the info Philip, let's see there is a Xiaomi.eu fastboot rom available hopefully it helps if doesn't better I would switch to some other phone, only Xiaomi phones which lasted with me long enough were Mi 5, and Mi Note 10, would love have Mi 5 again but those days are gone now as xiaomi has stopped thinking about there fans

I can confirm the Xiaomi.eu ROMs contain exactly the same modem files (they don't touch them), so I doubt very much it will be any different. By all means give it a go if you like.

Hi Philip,
Have you checked EEA firmware if that has it?

Yes I checked the EEA firmware. From what I've seen investigating my own issues with VoWiFi is that all the firmware regardless of region contain the same standard Qualcomm modem files, even across different devices, not just the 11T Pro.

Did you try to disable carrier check? Dial *#*#86583#*#* in phone and then the VoLTE option would appear into sim options.
