Gmail – How to Mark All Emails as Read

gmail

I was checking my email on my phone, and for some reason it glitched out and marked every single of my thousand emails unread. Is there any way I can mark all emails as read as once instead of doing 50 or 100 at a time?

If you go to the "All Mail" view from a computer (not sure how the mobile version works) and click the 'select all' checkbox, a little notification saying something like "All 50 conversations on this page are selected. Select all 24,037 conversations in All Mail" should appear, where the last part is a link. If you click that link, then click 'Mark as Read,' it should take care of the problem.
