My new Nokia 5 hanged 3- 4 times in a day and screen goes to restart automatically but after long time screen as it is , and when I use apps phone so me a flash message app is not responding so many time in a day .... I am very disappointing from my Nokia 5
I had a similar problem, so i switched off the phone and let it cool down cause it started heating. In the evening when i went to store for repair, the phone started working fine after a couple of restarts. Now it's working trouble free.
