Ever since I've gotten my refurbished galaxy s4, every time I play pyramid solitaire saga or candy crush soda saga it all of a sudden will restart my phone. My previous phone was a galaxy s4 and my husband's phone is also a refurbished galaxy s4 yet never experienced this problem before. I also play candy crush without this occurring. I have uninstalled the game and then reinstalled it to no avail, sadly it will still cause my phone to restart. Also, my phone doesn't restart due to any other apps or spontaneously. I hope there is a fix for this cause I love these games.
