In January, ZTE released the world’s thinnest smartphone in the 5-inch Grand S, only 6.9mm thick. However, some consumers found that the phone’s non-removable (and weak) 1,780 mAh battery paired with its quad-core processor and full-HD screen was not a good combination.
ZTE has decided to fix this issue by announcing an upgraded Grand S model called the ZTE Grand S Flex, with a 2,300 mAh battery. It’s a little bit thicker than its predecessor, but it’s worth it. The phone will be available in September in France, and judging by the pictures, there aren’t any noticeable design differences between it and the original Grand S.
