2 different problems: black screen and low torch.

[Bob12]

Hi, I had a problem with my sony xperia m5. Today, using chrome it freeze pressing the keyboard, then the screen go black and it will not answer to touch or.nothing. I pushed the on/off swith on the right but nothing happened, it at least gave me a little vibration two or three times randomly. It received calls and messages, i can hear the sound but the screen remained black. (87% of battery)
After putting it on charge it restarted, and now works.. What's the problem? Will it reappear?

Problem n. 2: i can see that the flashlight it's a bit low using the torch, and it's stronger in flash during taking a picture. Why? Can i resolve it?
Thank you

If it only happened once, it could've been an app acting up but you can get your phone inspected by your Local support

I'd prefer to not sending my phone to the assistance, because i had an xperia m4 aqua gone there twice for two different problems, and after i stayed a month without my phone they changed it with m5. I hope you understand that it's better if i can resolve that problem by myself.
What do you suggest?
What about the torch?

Repair the phone with XC and see if it improves, also, you might want to go to a store and test side by side the camera flash/torch

thanks! but as you can see, there's not a solution.. maybe sony have to resolve this problem with a minor update

After reinstalling update torch didn't change.
