Lost samsung galaxy s4 in taxi going from Oliver St. John Gogarty to Northstar hotel

It's a samsung galaxy s4 mobile phone with a black and grey seidio waterproof case. Please help me find my phone. My pictures and memories of my visit to Ireland is all on the phone. The phone is replaceable, but my photos aren't. I left it in a taxi at around 2-3am on March 12th leaving Temple Bar and heading back to the Northstar hotel on Amiens St.
