This model is still currently running on the 2018 december security patch...
You clearly got a problem to your device. Bring it to a samsung assistance service and explain the problem they should flash the softwsre update for you, act quickly before warranty expires
Are you comfortable with using Odin and flashing firmware? You could do that too but its more risky
Sorry but you cannot suggest procedured which make warranty invalid
Flashing a stock ROM does not invalidate any warranty
Oh yes it does, they usually are not ablento spot it but flashing it with anything else than smartswitch is warranty void
This comes from a 6 years android modder,inform yourself before doing flashing procedures

@AntS does flashing possibly invalind warranty?
Potentially. Which is why the official line is to have it carried out by an approved Samsung Support Centre.
Obviously up to members to make their own decision in the end, however personally I would also not recommend flashing due to the risk involved.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
