Unoptimized apps and faulty software updates

This thing is long overdue and needs to be talked about. Samsung doesn't optimize it's phones properly. What do you mean you phone will lag and be slow as you continue to update it's software? I'm using a budget phone, A16, I know...but at least optimisation is NEEDED for a phone to work well. If you don't support and optimize every update of a budget phone, then what's the point of naming it saying it will get official updates? Rather cut ALL TIES related to any budget smartphone. Take example, Apple iPhone, it's software is so optimized that an older flagship phone feels fast enough compared to a newer modern budget which has the upper hand of longer software updates and the modern technology it gets.

Another issue on Samsung is it's keyboard, Samsung Keyboard. Samsung Keyboard Is lagging and doesn't respond when typing to some apps. It even freezes when you're using Meta apps such as WhatsApp or Facebook. Updating the keyboard is obsolete useless as it doesn't FIX the problem it just FEEDS it. FIX THAT SAMSUNG!
