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.
Re: Grinding teeth/ tmj? cause dizziness? Grinding or clenching teeth may not cause the dizziness but if you are doing either to the point you strain your jaws and facial muscles then your eustachion tubes may become inflamed causing ear fullness or stuffiness and dizziness or feeling spacey. A night guard may help if you are grinding/clenching mainly at night.
