Samsung J7 battery going to 0% when using camera
I'm using a Samsung J7 (j700m) and there's something weird happening when battery reaches 40%/60%.
If I use the camera, some weird vertical black stripes start appearing on the screen, sometimes leading to the phone shutting off. Other times, it just turns off.
Then the device starts restarting like 3 or 4 times, and when fully operational it indicates a battery charge of 0%, just out of nothing, then it shuts down entirely until fully charging again.
If I manage to take a picture doing that weird camera thing, the photos end up having those black stripes (like a glitchy horror movie) and also sometimes there's a popup saying that there's no SD card recognition.
I thought this might be a battery issue and changing it would solve this problem, but I'd like some opinions first.
Thanks in advice for the attention!
