Heya,
so I don't know where to ask besides here.
I'm a phone repair dude and I'm having a small problem.
A client brought his phone to me with the problem of it sometimes not booting, getting hot whilst charging and discharging very quick.
So, I thought maybe it's just a faulty battery.
So said, done, I changed the battery. Same problem.
I can get into download and recovery mode. Recovery is still stock.
When I try to boot it normaly from turned off state, it displays the Samsung model, followed of the Samsung logo.
After it gets to the white state of the Samsung logo, the screen flashes lighty green, screen turns black and nothing further on.
I can reboot it into download or recovery mode after.
Anyone experienced the same problem?

Edit: here's a video of it:
