Updated to OneUI 6.1 and now the 5G/LTE internet speeds are inexplicably slower?

So I updated, and since then I have noticed that directly after a reboot, or after going into aeroplane mode and coming out, my base unlocked USA S23 goes at the normal data speeds for 5g and LTE networks but gradually slows down to a trickle that can barely load the https://google.com home page in 5 minutes.

These are the same towers as always, and my wife's S22 that is not yet on 6.1 does not behave this way, so it isn't a network issue.

I have tried clearing the cache partition, and re-optimising apps, but this hasn't helped.

I don't know why I didn't think of that. Were you having the same issue?

[terminator9]

yes and i went online and someone said to reset settings for network as this is all network related.

[mindsunwound]

Well that is done now, so we will see how it goes

worse case i can say if this doesnt work. do a factory reset... i know its a pain in the **bleep** but backup everything on google or samsung cloud and do it.. it has to solve this..
