Would my apple replace my iphone?

My phone is not respknding well all the apps i downloaded does not have a problem with making my phone mess up. It has a problem on black screens and never has been jailbroken. It has some problems on the speaker and also music plays by itself. Lots of crashing and my phone has a problem in the speakers it works most of the time but it gets annoying when it randomly turns blury. No i did no spill water and did not use a radio app. Lat but not least when i switch to vibrate it sometimes does not work. Will apple still replace my phone. It is still o warranty
