According to a report from China Xiaomi is quietly releasing a new batch of Redmi 4 units with reduced screen bezels. The new phones have visibly-reduced black border bezels around the screen and have a smaller footprint compared to the original. According to the report the new phones, which are sold directly from Xiaomi's website, are in circulation since January 11, though Xiaomi hasn't come out with an official statement to confirm this. There doesn't seem to be any other change to the Xiaomi Redmi 4 aside from the slightly-altered dimensions. Source | Via
