The updated Samsung Galaxy S smartphones will probably bow in 90 days or so, but they have just previewed the ‘A’ series. The next gen Galaxy A3, A5, and A7 feature faster charging, support for Samsung Pay, and upgraded cameras. 9to5google.com says the screen sizes remain at 4.7, 5.2, and 5.5 inches. The low end A3 doesn’t get fast charging, HD screen, and the upgraded cam. The A series will launch in China in a couple weeks, with a global launch a bit later.
Meanwhile, in Cupertino, word is that Apple may drop a new 4 inch iPhone with Apple Pay early next year. Theverge.com reports that the smartphone will have the same processor as the 6S, but keep the camera of the iPhone 5S. This word is from usually reliable KGI Securities. It reportedly will have a front glass that slightly curves at the edges like the 6S and 6S Plus, but WON’T support 3D touch. It may be between $4-500 without contract.
Samsung may announce one of it’s most promising phones soon. Bgr.com says it’s the Galaxy A7. It has a 5.2 inch screen and better specs than the S5, but has a metal case for a more ‘premium’ look and feel.
