The Sony Xperia C5 Ultra dual is a better option when considered from the camera point of view. It comes with a better front camera, a 13 MP with soft LED flash whereas the Samsung A7 comes with a 5 MP front camera only. The other factor which makes it good is a bigger battery but that is compensated as the A7 has a smaller display, making it more energy efficient. The Samsung A7 on the other hand comes with a slim design(6.3 mm only) and a lightweight approach(141 gm). The phone comes with a full HD display and selection can be made by considering your specific needs. C5 Ultra for photography and A7 for a lightweight daily use. The A7 comes with a price tag of INR 23,990.
