The Redmi 7A is more of a low-end affair, it’s powered by the Snapdragon 439 octa-core processor and built around a smaller 5.45″ HD+ display. Although, it’s missing a fingerprint scanner, but there’s a 4000mAh battery to make up for it.
While the Redmi K20 comes with the newly launched Snapdragon 730 and in-display fingerprint scanner on the Super AMOLED display, alongside triple rear camera. The K20 Pro is the same with its little brother but comes with SD 855.
The Redmi 7A has a starting price of $99 on AliExpress, while the flagship killers, K20 and K20 Pro has a starting price of $389 and $445 respectively for the 6GB/64GB variant.
