The myEyeQue app must first identify which phone it is running on and then compares it to the supported phone list stored in our database. The myEyeQue app recognizes a particular phone type by looking up the model number stored in the Operating System's diagnostics. Some phones, such as the Samsung Galaxy S7, have many different model numbers that can vary by cellular carrier and country. There is not a readily available database of model numbers and your specific model number for your phone may not be in our database. Many customers that live outside of the US may be affected by this the most. Please contact EyeQue customer support at firstname.lastname@example.org so we can address your specific model number. We'll add it to our database and notify you when it has been added.
