[Q] Z1 Compact phone freeze and reboot by itself topic

Im using Xperia Z1 Compact which i've bought and using for about 1 week. While I was typing a reply on Facebook. The phone suddenly freezes for 2-3 seconds and turned off, then reboot by itself. The phone was running only 2 apps which are web browser and facebook. I don't know the reason why as i performed basic phone diagnostics and check the RAM (which did not overrun). I also check the phone's temperature and it was only 25°C (my place was cold too). I was wondering if the self-reboot is because the apps? Malware or bugs? I am not an expert on technology, but I'm worry if yhere's anything wrong with my phone. Any help would be much appreciate? Thank you.

Xperia Z3 Compact Headphone compatibility topic

I already had older Xperias , and I had problems with the compatibility of headphones ... when the headphone that came with it stopped working , no other headphone I bought worked right . I saw that the Xperia Z3 Compact , at least where I live, comes with a simple phone , and the other from Sony are well expensive for me , as for example one with noise reduction. Would anyone tell me if I have this problem with the Xperia Z3 Compact ? Any headphone that works with him and that is accessible and good do you recommend ? PS : I live in Brazil . Thanks.
