Looking for smartphone recommendations

I currently have a Samsung Galaxy S4 and get my phone upgrade in mid September. I've looked at a few of the phones out now and they're all meh. I was hoping one of you guys could help me find a really awesome phone that's either out now or is going to be out later this year. Thanks in advance. I had my eye on the Galaxy Note 4 but it might be a little too big...

Personally i love my galaxy s4, and i am not sure why you would want anything different. but on the other hand i have been seeing a lot of good comments on oneplus one phone, so that could be a good option.

You're already using a very high end phone, why bother upgrading?

I was going to get a new phone and then let my mom have my old s4
