Why is my Nexus 5 screen freezing up?

[ckfilmstar]

This was the first time this happened to my nexus 5 (6.0.1).
My phone just went black and froze on me. I could see the all the WiFi signal, the time and among other at the top of screen.
The app I had running was called darker. Its where it dims the screen and gives it a red hue.
I tried powering it down but I could do nothing.
So I just threw my phone off to the side thinking it just died completely. To my surprise now its working.

What cause this?
Also, does that mean I need to get a new phone soon?
I haven't rooted this phone.

It is possible that the darker app caused it. Try uninstalling that app and see if it helps.

OH and it is froze, not frozed .

So its something nothing serious I hope.

Well my phone just died.
At first it would power itself off. Now I can't power it up anymore.
Is there anyway for me to retrieve some of my saved info in the SD card?

I don't have the darker app, still seeing this problem. Screen turns non responsive to touch. Hardware buttons are working fine. Reboot doesn't help.

I think some sort of circuit might have been broke. Can't think k of the word.
Unfortunately it would cost me too much for someone to take a look at it.
I wished these phones had removable SD cards. At least what ever I saved on there could be retrieved.
