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.
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.
