Kernel panic, followed by regular crashes

[Lelouche]

Yesterday my Galaxy Note4 (Android v6.0.1) showed a 'kernel panic' error screen followed by the 'downloading do not turn off target' screen which I left for a considerable amount of time before deciding it had frozen. Rebooting was a hit and miss affair with the phone behaving as if bricked unless the battery and/or SIM was taken out to boot. Once it had booted it invariably crashed again with any normal use.

I have since managed to do a partition wipe and a factory reset but the phone is still slow and often crashes to the 'downloading do not turn off target' screen needing removal of battery etc. to get it running again.

Is this fixable? Gut feeling is a memory problem/damage?

@Lelouche Your first port of call should be to contact Samsung support. http://www.samsung.com/uk/support/ They are more likely to understand your issue than anyone else.

Whilst it is still under the two year warranty I would get it checked out by Samsung (not O2). I had a similar problem with mine but Samsung here replaced the battery and it's been fine ever since. I'm running Marshmallow 6.0.1 for the last month and there was another major update yesterday so maybe it's trying to download that. It's 300MB+.

Sounds like a hardware fault of some sort esp if a factory reset doesn't fix it.
