ThejaswiRamappa worst company? From my experience Nothing is better than average. Xiaomi is the worst company in terms of support and bug fixing.
You can’t really compare Nothing with Samsung. Only recently did Samsung increase the years of software updates included on their phones. Samsung has been around for many years and has made lots of money to be able to guarantee updates. Nothing is still a relatively small company which surprisingly is being able to establish partnerships with great companies.
Give them time to grow and they’ll be better than Samsung, OnePlus, Google, etc.
