DAGGER DG550 is a low-cost but highly-acclaimed smartphone from DOOGEE, integrating a 5.5 inch (720P resolution) screen and an octa-core MTK6592, which is paired with 1GB of RAM. The terminal runs on Android 4.4.2 and has some bits and pieces customized by the manufacturer; the back camera is 8MP and the Selfie frontal one is 2MP. In the review we will carefully analyze the product and at the same we would like to announce the fact that for a limited time at GearBest this model can be acquired at a much lower price.
