Which sizes is the Universal Phone Case available in, and how do I know which size fits my smartphone?Updated a month ago

 The Universal Phone Case is available in two sizes: L and XL. 

 The decisive factor is the dimensions of your smartphone (length × width × height).

  Fits all smartphone models up to approx. 165 × 80 × 14 mm
•  Universal Phone Case XL 
  Fits all smartphone models up to approx. 170 × 85 × 14 mm

To determine the correct size, simply do a quick web search for your smartphone model together with the terms “dimensions” or “measurements”. Then compare your device’s dimensions with the maximum dimensions listed above for size L or XL.
