Installed Android 12 on S10 plus

[rap1021]

Overall performance has been improved.

Stutters here and there which is expected as it is the first build.

Camera app is faster now.

Will have to check battery performance in the coming days.

Edit -

Here how to do it.

1. First of all backup all your data because device will factory reset multiple times. Also remove sd card as a precaution.

2. Dial *#272*imei# and select Aut and click on install.

3. Select sales and network change.

Device will factory reset. Immediately remove sim card before device turn off.

4. Your device will boot to Android setup screen.

Fast forward the setup, just skip everything, you dont need to sign in to google or samsung for now.

5. When on the homescreen, connect wifi, go to software information and make sure it shows AUT.

6.Check for updates and Android 12 ota should appear.

7.install it as usual.

After installation, insert your sim card in sim 1 slot and test the firmware if you want.

8. When you are satisfied, make sure your sim card is installed.

Reboot to recovery and perform a factory reset/data wipe.

9. When the welcome screen appears, leave it till a message appears to install according to your network provider. In my case Airtel.

It will show you 3 options

Sim 1

Sim 2

Keep current settings.

Choose sim 1.

Your phone will reset again and original INS will be installed.

Congrats, you have successfully installed Android 12.

How is the battery backup for you.
Is it good or worse than Android 11..???

[LuciferMorningstarr]

It's almost the same, slight better than A11. I keep between 20-90% unless am on the road, & it gives me about 4-5hrs SOT on wifi +4G. With videos it can go up until 6-7hrs. I did a battery replacement last June so it holds up better

[rap1021]

How much time do they take for battery replacement.
Do you have to leave your phone or they do it on the spot.

[LuciferMorningstarr]

It depends. If the battery is available it takes 2 hours to replace it, so yes you will need to leave the phones with them for a while. I did it in Mumbai & they had the battery available. Do call up multiple service centers before you go there. Some of them have spares readily available while others say it might take a couple of days to get the battery. I was lucky to get it done in 2hrs

Ok thanks bro.

[rap1021]

Hey, can you check one more thing.
Earlier while viewing HDR videos, the youtube app used to brighten the screen automatically.
but now after the update its not doing that either.
Can you confirm..???

[LuciferMorningstarr]

It works for me. I assume you've enabled video brightness in settings for HDR apps

[rap1021]

That is not for HDR apps but for all video apps.
Youtube used to brighten the screen when playing HDR content even with it off.
This is a bug.
In camera, HDR10 is working but normal HDR not.

[LuciferMorningstarr]

Ok I was not aware of this. If I turn off the video brightness option in settings, YT doesn't brighten the screen.

[rap1021]

HDR is not working anywhere on the device
This is a huge bug, but we can't report it until s10 gets the ota in India.
