Small kimojis received blurry

I wont make the irrational complaint that these are not real emojis. Bc emojis are controlled by Apple not Kim but a complaint Ive received is that the small kimoji are received blurry to those I send it to. Please fix.

Also, the keyboard is unstable- it can work one day and stop working the next.
