My mother recently got the Samsung A71, but struggles to attach a photo (regular captured photo) to her email (Gmail app - not the email app from the phone). At first it looks like it attached, but when it's busy sending the message appears "Attachment too large" and then the mail don't send. With her old phone (Huawei P20) she used send photos (similar to the ones she wanted to send now) via Gmail without any problems.
