My Samsung s20 ultra has problems answering and recieving calls. many calls are dropped. i have to answer on speaker phone then on earpiece to be able to talk .
answer button is not visible i have to swipe down to notifications to answer any calls
also vampire drain of battery and it is empty with no warning, i have all latest updates still problems.

> Update all apps in the Playstore and Galaxy Store.
> Check for any available software update in Settings > Updates and or via Samsung Smartswitch.
