My Device name is Samsung Galaxy A7 2018 and am using the same for the last 23 months. Today afternoon I got a serious issue with this.
The issue was that after using it for continuous 3 hours of my live lectures, I kept it in charge and left for few minutes. Later when I checked, it was already started to reboot and was showing the Samsung logo screen. I waited for several minutes to get it ready, but nothing happened for next many hours. Later the phone got automatically off, maybe due to exhaustion of battery charge. So I plugged-in again for 1 hour and tried switching on. But still the same Samsung logo screen was was showing as frozen for long time and no other response.
It kept on showing the same screen for long time and it was never turned off until the charge gets over.

Kindly help me with this issue. I have around 20 days left for the warranty expiry date of this device.

Some other issues I faced while using this device are listed below:

1. Over-heating of device while using camera for more than 5 minutes.
2. Taking too much time for running or loading apps, comparatively very slower network/bandwidth speed with other Samsung mobiles in the same home network.
3. Loosing camera quality after a period of time.

I have been a continuous user of Samsung for the past many years, Most of the electronics or mobiles devices at my home or used by my family are Samsung products. So I trust you could help out in this issue.

Hoping for your kind response soon
