How long do ZTE phones get updates?

Rarely publishes fixed commitments; budget Blade phones typically get ~1 OS upgrade + ~2 years of security, Axon flagships a little moreOur estimate

ZTE does not advertise a guaranteed update schedule the way Samsung or Google do, so software timelines are estimated from its track record rather than an official promise. Its phones also have limited and highly varied global availability, with many Blade and Axon models launching in China, parts of Asia, Europe, Latin America or Africa and never reaching the US officially. Buyers outside a model's home market often rely on imports with reduced warranty and update assurances.
