The phone has 4GB of RAM for your apps. This is gives you plenty of memory capacity. You can even play cutting-edge 3D games. The internal memory capacity defines how much space will be left for your multimedia and files. If your phone's internal memory is under 1GB, you will only have enough space for the bare minimum needed to run the phone. You will be able to upload text-based data, such as notes or contacts. A larger flash memory with a 16GB capacity is the least you need if you want your phone to be "smart" in the true sense of the word. If you opt for a model with a 32 or 64GB capacity, you may not even need an extra memory card. A storage capacity of 128GB or more gives you enough space to capture hours of high-definition video. If you want more, you can always expand the internal storage of your Doogee S55 black with a memory card.
The Doogee S55 black is equipped with a camera with a 13 Mpx image resolution. This means the phone is suitable for taking high-resolution pictures you can crop and edit later on. The front side has a camera with a 5 Mpx image resolution.
