Phone become black screen and can't restart

[StygianZ]

Yesterday, i left my phone at a side while doing other things. When i check back my phone, it died and cannot boot up or restart. I tried pressing the reset button and force restart, but have no effect. I thought it was out of battery so i went and charged it. To my surprise, it does charging because there is a red light, but i still cant start my phone or anything. Please help me, I buy this phone only for 1 month.

i have a similar problem today. Battery charge was about 80% when i saw my screen last time. I start "ingress" and put down phone in pocket. through 10-15 min i took my phone and pressed power button. Phone not power on. I charged my phone 1 hour when I got home. But phone not started. I dowenload SUS and pressed volume down button and connected phone on computer. But phone not conected.
