My dad got angry at me for not making a decision?

I came back from a mobile phone shop and my dad was trying to convince me to get an android phone. But it was a bit laggy and i didnt really like it, as i had used an iphone for 2 years and had gotten used to that. afterwards he just gets really angry at me for not buying it, and that he wont help me through all this again. my aunt and cousin were there too and i just felt so embarrassed. i almost cried cos hes usually the one saying' if youre not sure about it dont do it', and then he blames me for not being able to make a decision. i really felt bad and threw my old phone (its a really cheap one) against the wall so the screen is shattered and starting crying. what should i do? :( (im a 19 year old male from pakistan)
