We have designed each detachable piece/adapter to fit the measurements of each listed phone. This means your phone will work and fit best without the case on. There are too many types of smartphone cases on the market to create pieces that will fit different phones with these added variations. Keep your phones naked!
When the campaign is over and you end up getting a different phone, you can contact us at www.trobla.com and order a new adapter directly from us. We will also create new adapters to fit future generations of smartphones once they are released.
