Use the comparison table to choose based on the price, condition, and specs that matter most to you, especially ram / storage variants and official colours.
Infinix Smart 20 is the better fit if its advantages in ram / storage variants matter more than the savings on Redmi Note 15 Pro+ 5G; otherwise compare current prices and availability before buying.
Redmi Note 17 is expected for a July 14, 2026 China launch. Nigerian buyers should verify warranty, ROM, 5G bands, battery terms, charger and local price before importing or waiting.
