I personally have only 3 problems with my new Samsung S6. #1 being that my fat thumbs make it hard while texting, as I'm use to have a physcial keyboard when I had a Droid 4. #2 The S6 is still slow for me. Pauses and runs slow (I even make sure I'm not running any apps for no reason) And also after downloading apps I had on from my previous phone, it started to run slower than what it was. I text fast and it has a hard time keeping up with me. #3 is the fact I'm at 2GB left out of 32gb and I barely have music, and/or videos on this phone. Its mostly due to apps being downloaded. I miss the fact I had an external memory slot for the SD Memory cards.
