European and HK/Global version have the same 4G and 5G band support according to the spec sheets.
My post highlighted the differences between the Japanese model and the European model. I wasn't trying to say those are the only bands supported, only which bands are different based on the spec sheets.
I am aware each European country has their own bands.
Happy to hear you have so many supported bands in Italy. I wish I could say the same about US bands!

Able to do a dummy guide for changing power button to press to unlock? The guide from Reddit is not dummy at all...

haha! I was just thinking, why isn't this an option?? feeling the fingerprint scanner attempt and fail to read every touch was getting a bit annoying in a way.
which guide did you find? I found one on reddit but haven't read it through yet. quick skim seems like it requires accessing the phone via adb

When I have some time, I'll take a look and see if i can create a "dummy" guide to share here.
Have you worked with adb before?
Essentially, you will need to enable developer tools and allow USB debugging. install the android drivers for your machine (windows, mac, linux) and download the android SDK (this has the adb and other executables in it).
Once you have all that. When you plug in your phone, your computer will recognize it as an android device and you should be able to access it via adb commands from a command prompt/terminal.
Anyway, if that doesn't clear things up, i'll work out a guide when i have some time. It is something I'd like to enable myself but didn't look at the reddit guide closely enough yet.

Yeah I never touched adb before. That's why super noob in these Matters. But thanks a lot for spending efforts ! Even if it's too complicated just state so because it's not a must do job. I do appreciate your assistance 😊😊😊 Sony should do it right in the first place.y

I agree. Sony shouldn't have taken away the setting in the first place. There's absolutely no reason to take it away. The only thing I can think of is that the feature was buggy and they simply didn't want to deal with complaints about it?
Anyway, it is not super complicated but if you are a super noob, it does require some step by step explanation with screenshots. So, that will take time to get together. I will get to it eventually!

Yes, once you unlock the bootloader and gain root access, you can view the modem policy files that are on the phone. I did not look at the stock files to compare and simply overwrote them with modified ones. I probably should have, but eh, whatever
When I say "disabled" it means they were not listed in the modem policy files despite the hardware supporting them. Sony does not sell in the US, so my problem was essentially overriding the region block that's in the policy files. Essentially, they did not have enable 5G bands if the location detected was in the US.
From my brief comparison, there are some differences in band support between the Japanese and European model. Based on spec sheet, these are the bands supported by each model where the other does not:
4G:
Japan - 11, 18, 21, 42
Europe - 20, 25, 32, 34
5G:
Japan - 66, 257
Europe - 7, 8, 20, 38, 40, 75
The european model supports more 5G bands overall. Based on
this site, the Japanese model supports all but one 4G band and all but one 5G band currently being used on carriers in Sweden. I would not worry too much about unlocking and rooting until you find out your carrier is intending to switch up all their bands completely to unsupported bands.
To answer your question about factory reset, yes. Unlocking the bootloader alone does not do a factory reset, but gaining root access does and you need root access to modify the policy files. Once you are done doing what you want/need to do, then you can relock the bootloader so you can utilize financial apps and tap to pay, which use the locked status of the bootloader as a security integrity check.
Let me know if you have any other questions. I hope I explained well enough.
Thanks a lot for your explanation.
For the moment, I realize that this isn't my thing.
My operator Tele2 uses n78 and 1, 3, 28 which my Japan 1 VIII support.

I had a minute and was able to turn on the option to only scan for a finger print after the power button is pressed. Very easy.
Here's my "dummy" guide.
Install the drivers and SDK suite. Follow the directions to install the driver at the links.
Google USB drivers
https://developer.android.com/studio/run/win-usb (this is for windows)
Android SDK
https://developer.android.com/tools/releases/platform-tools
Enable developer options on the phone
1. go to SETTINGS > ABOUT PHONE
2. Scroll down to the firmware version and tap it 7 times until developer options are enabled.
3. go to SETTINGS > SYSTEM > DEVELOPER OPTIONS
4. Enable USB DEBUGGING.
Connect your phone to your computer and unlock it.
1. Verify your phone is recognized by the computer in windows device manager. (search for it in the start menu)
2. Look for PORTABLE DEVICES and expand it. Your device should be listed.
3. If your device is not listed, check to see if is listed as something else with an error icon. If this is the case, you will need to disable driver signature enforcement. Go to your windows SETTINGS > SYSTEM > RECOVERY > ADVANCED STARTUP and click RESTART NOW. When your computer reboots to a blue screen you will see options. Select "Disable Driver Signature Enforcement". The computer will boot up into windows as normal.
4. Connect your phone again, unlock, and check the device manager again. It should be detected as described above. If not, you will need to manually update the driver for the device that has the error icon and select the driver you downloaded above.
Use adb
Once your phone is connected and recognized, you can use adb.
1. search for command prompt in start. when it shows up, right click and select RUN AS ADMINISTRATOR
2. In the command prompt, change directory to the directory where you saved the SDK. The directory should have an executable called adb.exe inside.
3. Now run this command exactly: adb shell settings put secure somc.disable_fps_screen_off 1
4. Your phone probably pop up a prompt to allow connection to the computer. click ALLOW
5. If the command prompt says "adb.exe: device unauthorized" even after you click ALLOW, just run the command again.
6. The command will execute and you will be returned to the prompt with no other notifications.
7. At this point the feature to enable the fingerprint scan after pressing the power button will be enabled.
If you ever want to enable the always on fingerprint scanner, open the command prompt again via administrator and run the above command again but replace the "1" at the end with a "0".
Once done, you can disable USB debugging in the developer options again, if you want. I do it, just for security reasons.
QUESTIONS?
I didn't have time to take screenshots and post them and link them all here, so hopefully you can follow along with what I wrote. If you have questions, let me know! I think the hardest part is making sure your phone is recognized when connected to your computer.
Good luck!
