How long do Infinix phones get updates?

Infinix runs XOS on budget hardware, and its support is tiered and generally short. Higher Zero, Note, and GT models get up to two Android (XOS) upgrades and around three years of security, while the standout Note Edge was promised three years of OS upgrades and five years of security. Budget Hot, Smart, and XPad lines often get only one OS upgrade or none, with limited patches. Infinix isn't available through official US retail and targets emerging markets; like sister brand Tecno, its timelines circulate mainly through community and support channels.
