iOS update on iPhone 6s
Is it okay for me to update my iPhone 6s with the latest IOS software updates? I’ve had mixed reviews with some people telling me it will affect my phone cos it’s reasonably old and some saying it’s fine to do it and won’t affect it at all. So because of this I haven’t updated the software since IOS 14. Normally I do it the moment it’s offered. So just wanted some advice.
