After being dissatisfied with the A6, I upgraded to the A7. 1. The quality of the communication in A6 when traveling outside of the city was significantly improved by two orders of magnitude. A7's grip on the nearby tower is so shaky that the situation is a complete and utter catastrophe. 2. The A7 also has a lower battery capacity than the 5000 seen in the A8. 3. The fingerprint identification feature, which was quite useful in the A6, has been removed from the A7. 4. Although the amount of RAM has dropped by one gigabyte, there is now more garbage as a result of unused apps. 5. The three control buttons located on the surface of the device's side are completely useless know-how. In other words, the A7 is a watered-down version of the A6 that costs the same. However, it will suffice for the position of "state employee."
