Do screen protectors affect smartwatch touch sensitivity?

Quality protectors — both glass and film — have negligible impact on touch sensitivity. Ultra-thick or poorly fitted protectors can cause issues. Stick with reputable brands and you won't notice a difference.

How often should I replace a smartwatch screen protector?

Replace when you see deep scratches or bubbles forming. TPU films may need replacing every 2-3 months. Tempered glass lasts 6-12 months. Self-healing films sit in between at 3-6 months.
