Hello, i'm thinking of getting this phone but i've been with iOS for nearly 8 years. Been doing some reading and one review said that android tends to release less updates if compared with iOS. True?

How about Android OS over time, is the lag noticeable like the old times?

Android has improved in leaps and bounds over the years. Rest assured any flagship grade Android with 4GB RAM or more won’t give you any lags like the Android devices of old. That said, I would recommend you go for the S9+ rather than the S9 if future proofing is important.

Unless you’re on vanilla Android (i.e. pure Android with no manufacturer’s interface), then yes, updates may be slow and far less compared to iOS, but that’s not necessarily a bad thing unless there are vital security flaws that need fixing.

Yours sincerely, iOS user (and still is) for more than 8 years
