The Slider Case can be removed by using a latex glove to grip the Slider and pulling the top portion off from the bottom where the sliding portion meets the top portion. Squeezing the case from the sides will just make it more difficult to remove. It will take quite a pull to come off so it might be a good idea to get assistance. Please contact us if you have any problems.
We do not recommend the use of a screen protector with our slider cases unless it is the Incase version which is custom sized to fit and work with our slider cases. Incorrectly sized screen protectors are the main cause of slider cases binding up on the phone.
