Phone won't turn on (Samsung Galaxy A7 (2018))

[imjakedeason]

So, I have this problem that started earlier today. My phone (Samsung Galaxy A7 (2018)) had around 5% battery and I wanted it to drain fully and then charge it fresh. As I went to grab my phone I've noticed it has been off and I just plugged in my cable and left it. Phone then started to turn on by itself and you could feel/hear a vibration and see "Samsung Galaxy, powered by knox" and right after that screen turned to black, it went right back to it again. Vibration, Samsung powered by knox, black screen... 

I would turn on at all. I disconnected the cable and tried to turn it on but nothing. Only time i could get any feedback from my phone is when it was conned to the power, either charging in the power socket or in my pc. I tried to enter boot mode but I won't. I could only enter download mode and that's all. I looked online and I couldn't find anything similar to my problem except one. I followed the solution for the first problem but that didn't helped either.

Can anyone help me.

Hi @imjakedeason 

My rule of thumb with my phone's is to not let it get below around 15% as a phone can sometimes have issues otherwise. Not all the time I might add but it's my own personal opinion.

You could try a soft reboot samsung-galaxy-a7-2018/softreset. 

Or if necessary a Hard Reset but this could delete your stored information samsung-galaxy-a7-2018/Hard Reset.  

Failing that a Samsung Experience Store or Samsung Service Centre can help.

I wish you all the best with this situation.
