Hello and Welcome to Just Answer. My name is ***** ***** I can help you with your request, but I need to know a bit more information about your phone.
- Can you please tell me the full model number for this phone? Samsung currently has many cell-phones made worldwide that has the number "5" right on it, so can you please be a bit more specific.
If it is the Samsung Galaxy S5, and it is a Genuine samsung device, it will have the Play Store pre-installed.
