Texting and Frequently Used Emojis

I use emojis a lot, mostly the same ones and more than enough to fill the frequently used space, which was bigger before the update which enlarged emojis. Occasionally I'd use a different one, which would replace a more frequently used one; recent seems to be the operative word, not frequent. Frequent would be more useful, perhaps you could expedite that to match your claim.

I experimented once with the feature enabling memojis within a text. These have since been a permanent feature in 'frequently' used; I have neither used them frequently, recently, nor once by mistake. I have deleted all custom memojis and have sent hundreds of 'standard' emojis, in an effort to remove them, but they remain stoically in position. I want them off my phone!!!

For some considerable time, it has not been possible to read the 'above' received texts while replying. It makes it impossible to check that I have addressed all questions raised. Please sort it out.

Updates used to be mostly about 'bug fixes' and security. Recently it seems more about adding more intrusive distractions which you can't opt out of, or the method to do so becomes more deeply hidden.

My general option not to use Siri has been completely over-ridden, by your update, and I have the tedious task of turning it off in each individual app. AND why does it keep appearing while I'm competently using the phone and in need of no help.

Which brings me to... Why is the camera constantly appearing for no reason?
