Panic log analysis - 1 to 3 crash-reboot /day

Hi,

I have a refurbished 1 year old iphone SE 2020. It keeps restarting randomly 1 to 3 times a day, sometimes while using it, sometimes making a call, sometimes unlocking it with touch ID, sometimes when the iphone is sleeping.

At some point i could not make a save with itunes (i could syncronise data like music and photos though), the memory could not be read nor written (maybe a separate issue).

I recently decided to wipe it clean to see if the issue persisted and here it goes again like before. The issue started to be annoying maybe 2 to 3 month after the purshase, but i did not care at that time, of course i should have reacted faster.

I am trying to find what the cause is before changing (if there is) a faulty component myself or telling the vendor he sold me a faulty product.

I tried the "idevice log analyser" from waynebonc, it doesnt find my logs while detecting the iphone on my PC so here i am.

I hope you can help me guys, thank you very much !

Here is several types of panic-full events :

1/ SEP Memory protection error ?
