An extremely low-cost chip suited only to very cheap phones and basic tasks. Clear limits in connectivity and storage make it a poor fit if you want a phone that lasts for years or genuinely modern performance.
- +Very low power draw, which helps battery life
- +Support for displays up to 120Hz
- +Very low prices on the phones that carry it
- −No 5G support at all
- −Dated, slow eMMC 5.1 storage instead of UFS
- −Relatively dated core architecture (Cortex-A75/A55)
