Yesterday , while playing, my rog phone5 frozen ,and I could do nothing. The only solution was to turn off the phone. After that, the phone never started again. When I was playing the phone was not even hot,max 30 degrees. I'am very disappointed and I have no idea what can cause this. I have played this game on other phones and for years ,but I never had such problems.
You're not the only one. 80 percent of the people here (including me) have faced the same. Only option is to going to service centre and replace the motherboard. Additionally, say goodbye to the performance you were getting before.
