I did a force restart but when i try to unlock my iPhone it takes several swipes up before the keypad even shows.
also when texting the keyboard does not work properly in upright position, i have to put the phone in landscape position to use the keyboard. all this right after the 18.6 update. my iPhone 12 Pro Max was working fine until this update.
Is the battery in your iPhone, the original battery? iPhone 12 was released 5 years ago. The battery could certainly be failing at this point. Open Settings > Battery > Battery Health - what does it show? If below 80% the battery is failing and you need to pay to have the battery replaced.
I know you want to blame this on the iOS 18.6 update. If the update caused such issues, it wouldn't just choose your phone. It would affect everyone's phone. This forum would be flooded with complaints if it was the update, yet it's not.
Otherwise, it's time to schedule an appointment at your Apple Store Genius Bar to have your phone tested. Smilin-Brian provided links in his response you can use to do that
