My phone switched off every time I fold it!! Yhe phone has never been dropped, or been in water it looks like new.
This looks like a common problem with this device which os no fault of my own, surly Samsung should replace it ( preferably a different model) it's around 7 months old and supposed to last at least 2 years 🤣
I too have seen a few similar posts to yours @Stu JJ
Please seek support from a Samsung Experience Store or Samsung Service Centre.
I wish you all the best.
