This is like saying you don’t want an apartment/house with a bathtub because you don’t take baths. Most people choose based on features they want regardless if it has one feature they won’t use. It’s just not generally worth the tradeoff of limiting your options when it’s such a common feature. If you absolutely can’t use a phone with a front facing camera though, then good luck with your search (genuine, not sarcastic).
