This smartphone is a version with good processing, a slim design and a neat technique.  

The design

The Samsung Galaxay 7 A is a very thin smartphone (about 6.3 millimeters without camera bulge) with a simple appearance. This makes it visually very appealing. The camera looks a little bit stronger at about 2.7 millimeters than the competition models, which also have a much thicker enclosure surround. The case of the A7 is made of aluminum Also a case for memory cards up to 128 GB is available.  

the display

The display has a size of 5.5 inches and a resolution to 1920 x 1080 pixels. The sharpness reaches a good value of 401 ppi. This allows you to recognize even small fonts in a very sharp picture. Also a lateral readability of letterings as well as corresponding contrasts can be seen well. However, if the sun appears on the display, you have some difficulty recognizing the contents on the display. However, the contrast values are significantly better. This version can be measured with the other Galaxy models.  

The memory

Of the total installed 16 GB memory can be used ex factory approximately 11.2 GB freely. The microSDXC card is expandable up to 128 GB. It is also possible to manually move apps back to the memory card.  

The camera

Here is a 13-megapixel camera used. With 5 megapixels the front camera releases. The tripping is carried out with a triggering delay of 0.12 seconds and with a storage time of 0.55 seconds. This is very fast. The photo quality can be compared with the other Galaxy devices. In some cases, a visible edge clarity and a smaller picture noise as well as fine color fringing occur at the contrasting transitions. However, when there is hardly any light, almost nothing can be seen. Good shots succeed in moving pictures. This is where the camera is used. Videos are recorded in full-HD quality with a very decent quality.  

The battery power

In order to get a slim housing, the capacity at the battery was somewhat reduced. Thus the battery installed here has only a capacity of 2600 mAh. This is about 315 mAh less than the previous model and about 600 mAh less than the Galaxy Note 4. Likewise, a Turbo-Lademodus is not present. Also lacking the capability of wireless charging. Due to the fact that there is no retrofit possibility, because there is no interchangeable backside, this is already a certain disadvantage. But the positive thing is that the built-in Samsung processor runs very sparingly and thus not so fast to the charging station must. With an average runtime of approximately 11 hours with normal smartphone usage, the performance keeps about 2-3 hours longer than competitive models.  

Working temperature and operating comfort

This execution runs very consistently. 2 gigabytes of RAM and an eight-core Samsung Exynos Octa 5430 processor. Depending on the requirements, the CPU operates with four high-speed cores (1.8 Gigaherz) or four energy-saving cores (1.3 gigahertz). This Galaxy version is equipped with an Adrioid 4.4 KitKat. This is a somewhat outdated system, but it works much better than the latest version. As far as the user interface is concerned, this is somewhat easier to use than the predecessor models. If you are not interested in the version data, however, the version 7 is similar to the top 6 versions.
