As a security technologist, the security philosophy of the OEM is a crucial determinant of my decision to buy or recommend a device. This is where Apple shines with it's iPhone update strategy. Every single iPhone receives updates (security and version) at the same time. 

This is why I highly recommend Google's Pixel devices. The Pixel line offers the same regular and speedy update schedule. The other Android manufacturer that has shown it cares about upgrades is OnePlus. Until this week, it did a great job delivering updates quickly, but it didn't formally commit to a software upgrade schedule. 

All of that changes this week when OnePlus unveiled its new operating system (Android) maintenance schedule. It has copied the Google Pixel model and will deliver major upgrades for two years and security updates for three years. 

Conclusion

OnePlus has always offered solid well-designed devices at competitive prices. This new software maintenance schedule commitment makes their offering that much more compelling. 

I can no longer recommend devices from manufacturers that do not regularly deliver security and version upgrades. This is why I only recommend Android devices from Google, Blackberry Mobile and OnePlus.
