To DIRECTLY answer the OP's question: No, not for when I'm taking a serious photograph. However, the majority of photographs/pictures that I have are from my phone. Reason: ease of taking a picture.
But, I'll digress for a second...

Wow, I must be in the minority on this site with my phone camera. I use my phone camera for lots of stuff.
Would I use it in a "professional" setting? No.
Would I use it in a casual setting where I'm not concerned about getting a perfect photo (e.g., capture a memory or post to social media)? Absolutely, positively yes.
Would I want to ruin the mood on a nice walk along the beach with my wife by bringing a tripod and DSLR? Absolutely, positively no.
Within the last 2 years that I've had my iPhone 5, I've taken thousands (literally) of pictures. Sometimes they are when I couldn't/didn't want to bring my DSLR with me. Sometimes they are pictures of my dog. Sometimes they are of documents that I signed and converted into "scans" using an app. Sometimes it's when I'm in a store and need to ask my wife whether to buy Product A or Product B.
While I would love to take my DSLR with me everywhere I go, I recognize that it's not always possible or feasible. That's when my phone camera (and sometimes P&S) comes into play.
