The Samsung Galaxy A8 has a fantastic 5.7-inch full-HD Super amoled screen, which is among the best we've seen in the 1080p category. It's bright, sharp and detailed, thanks to the amoled technology. Blacks are deep, while colours are vibrant and full of life. Motion and touch sensitivity are also excellent, and despite the size and relatively low pixel density.The A8 is a dual-SIM device with both SIM slots supporting 4G SIM cards. However, 4G can only be used on one SIM card at a time, with the other dropping to 3G. Furthermore, the second slot is a hybrid slot, which means it doubles up as the microSD slot. You essentially have to choose between dual-SIM connectivity and storage expansion.and thish phone is good for me.
