UI 2.0 bug Wifi disconnect when phone stanby

[Pro4]

Wifi keep getting disconnected and reconnected when phone is in standby. Probably it is being deliberately done to preserve some battery.

Long back, few phones had option in wifi setting to keep wifi ON during standby, but not anymore.

I believe this is not hard to reproduce and it should be impacting other phones as well, especially M series.

Will Samsung one UI R&D take note and see if it is possible to fix. I have M31.

Check if your phone is in battery saving mode...If it is then pls turn off the battery saving mode and check...

[profficial001]

check if any other third party apps are controlling wifi or not...

Thanks much for your response.

1. Phone is not in Battery saving mode.

2. Third party apps aren't controlling wifi (see attached pic).

disable wifi timeout option and enable keep wifi enabled during sleep option

Where is that option?

I dont see that in M31 UI 2.0.

This option used to be there, not sure why it has been removed.

[ezpser]

it still there under advanced option . ( show more )

well....it's not there in my M31, which phone do you have? if it is there.

If it is there in some models, I wonder why it is not in all the phone. That's something basic.

Without that option, wifi keep getting disconnected when standby.

when I use 2.4ghz band wifi then it works fine. However, the problem comes if I use 5 ghz band wifi (which is latest).

Not sure if Samsung tested 5Ghz wifi.
I am forced to use 2.4 ghz band now in order to avoid this issue.
