Question Bluetooth problem in Xiaomi 12t (not the pro model) - Xiaomi 12

Hi all,
I am using miui global version 13.0.5
I had some problems with the Bluetooth where when I turn on the Bluetooth it cant scan any other Bluetooth device and when I use another Bluetooth device to scan, my 12t is not found.
But, when I just got the phone the Bluetooth still worked properly.
I already reset the network, wifi, and Bluetooth, I already cleared Bluetooth data, and restart the phone.
Any idea how to fix it?
Thanks

Type bluetooth in the search bar of the settings, it will display more options, note bluetooth search to activate just in case.

Maybe between the time it worked and the time it didn't work, there was an update to the app that controls your device, try to see on this side.

If there was a rom update and it worked before, that's probably it.
I've had similar issues with watches and only factory resetting the watch fixed the problem.

Surely, but have you tried with several devices to be sure that it does not come from this side.
And have you tried connection sharing with Bluetooth?

I already try it with 4 devices to be sure and it still cant.
i cant do connection sharing because the device not even shown in other devices.
or is there any way to do connection sharing without connect with bluetooth?

My last suggestion would be to check Google Settings<Android Device Manager and enable the two options.
If this doesn't work then you could try clearing Google Play Services data as per this suggestion.
It seems an update to Google Play Services can sometimes disable the Device Manager.

It seems that the problems is because of the Snapdragon app, Battery Guru, on the settings it disables Wifi, and i unnistall it, and now it seems to work perfectly

Probably a setting in there to disable WiFi, but honestly you don't need Snapdragon Battery Guru. The OnePlus battery is amazing as it is, just stick to basic battery conservative tips such as eliminating wakelocks from occurring to ensure your phone deep sleeps.

Use search, here are couple topics about broken wifi after update. Factory reset should fix it.

Hi!
Have you got Passpoint running?
This might be a totally different issue but if a factory reset or reflashing doesn´t help you might try looking here.

I have the same effect!
A full reset won't fix this problem. I contacted Samsung support and the said that I should send them the tablet.
A reset usually isn't sufficient, you need to reflash the firmware.
I fully reset the tablet about 4 times and it suddenly works.
Hi all!
I have exactly the same issue.... I just updated my Note Pro LTE (unrooted) to the latest firmware and I also do not have access to wifi.
Could you please help me? I read in this thread that by reflashing might solve the issue, but since I am not so experienced with that stuff on Android (hence the reason I never rooted), could you please provide detail instructions what exactly I have to do?
Thanks a lot for your great help!

I eventually made a factory reset and after everything was finalized, wifi was running again fine. All my apps from play store were installed again automatically and everything seemed to run properly!
However, when I woke up this morning, unfortunately the same issue was present. No network connectivity and all available wifi networks were marked 'not in range'!!
Thus, it seems that factory reset does not solve the problem... Therefore I searched on google how to reflash my tablet. This is the link that I found:
http://androidcentral.us/2014/02/how-to-flash-firmware-using-odin-samsung-devices/
Could you please confirm whether this is the procedure I should follow? If yes, which update should I use? The latest or the previous one, i.e. P905XXUANH3 or P905XXUANC3?
Also, will Knox be tripped if I flash the firmware?
Thanks a lot for your help and I look forward to your responses!

I usually direct people here: http://forum.xda-developers.com/galaxy-s3/help/guide-odin-flash-guide-t1671969 (It's for the S3, but the procedure is the same everywhere. Make sure you get the most recent version of ODIN. The three buttons have different names (Bootloader/PDA/Phone/CSC are now BL/AP/CP/CSC), but the order is the same.)

You can't downgrade, so use either the one you already have or a newer one.

If you use the official firmware for a country in your region, No.
Thanks a lot ShadowLea!!
Eventually there is no need to reflash the tablet....
The only thing I just did was to uncheck the Passpoint option, as Polar67 describes above, in the Advanced Settings of wifi and immediately the issue was fixed!
Thank you all for your great help!!

Question Spotify has no connection to WLAN

Hello all
My ROM: MIUI Global ROM 13.0.5 (SLAMIXM)
I have a strange issue with my 12S Ultra using Spotify or a Browser of any kind. When connected to WLAN Spotify has no connection to the Internet and I noticed that when I tap on a sponsored google-ads link (on the top) on any browser on the phone, I get a "Connection Failed" message, Spotify on the phone on web works fine, Browser link on the PC work fine too . This happens to two completely different Internet environments at different house's too. I posted my issue to the Spotify Forum https://community.spotify.com/t5/Android/No-Connection-with-WLAN/m-p/5476052/highlight/true#M195356 but nothing helped. It seems like some kind Firewall on the phone is blocking the lines, but nothing is activated and I don't have an Antivirus either. Factory Reset didn't work, reinstalling the app didn't work, I even reset my router didn't work, but it's obviously a phone related problem I think. Do you know how to fix that or if I should install something to get it to work?

afaik the ROM is a custom one from the XIAOMIUI community, so that Google Play Store can be installed as it's restricted in china. So you think updating would help? Its only this two issues so far, I set a whole smart home configuration on Google Home, and it works fine over WLAN. The problem is, Google Backup doesn't work either, that would mean that I have to configure the whole stuff again, because the Xiaomi Backup doesn't backup app settings it seems

By flashing the latest version and erasing the data, your phone will be as it should be.
On Xiaomi Eu roms, the play store is certified without root.
I understand that reconfiguring everything can take time but normally you will have a working phone with updates.
