There are several waterproof smart phone cases on the market today which work very well. Unfortunately, these dedicated cases are not designed to be taken on and off and can cause problems when trying to use card readers, docking stations, video adaptors, etc. If your daily use case is not up to the task of outdoor activities, this Dry Pak bag is the ticket. It is not only waterproof but also floats and features a clear back panel for taking pictures. The touch screen can be accessed through the clear TPU material to make calls or use GPS navigation apps without exposing your device to the elements. You can also store other small items in the case that must stay dry. Great for both backcountry trips and urban emergencies. The lanyard feature prevents your valuable items from loss and falls. Measure 4' x 6".
