my iPhone won’t let me type the word “bus” it changes it to bud

I hate having the period/fullstop on the right hand side, as I always hit it when I hit the space bar

You can go into afib briefly then go back to sinus rhythm - I get it after certain triggers like alcohol (usually the day after), salt, coffee, licorice

run it and charge it until the battery drops below 80% then send in for battery replacement, they will replace the whole thing
