The Passport comes with a 4.5-inch square touch display with a 1440 x 1440 resolution and 453 PPI pixel density. Thanks to the integration of a touch-sensitive panel inside the hardware QWERTY keyboard below the display, your fingers almost never get in the way of reading or otherwise interacting with on-screen content.
Injury to the outer ear is by far the most common cause of tenderness and pain. The injury is usually obvious like with an ear piercing or blow to the ear. Trauma leads to inflammation which is characterized by pain, redness and swelling.
Painful lumps behind ear causes include: 1  Abscess â These are lumps that develop when tissue or cells become infected. 2  Dermatitis â This takes place when waxy dead skin cells or dry skin builds up and is joined by inflammation and redness. 3  Mastoiditis â The mastoid bone is found behind the ear and can get infected.
