Just trying to be honest. First time wasn't their fault. But a console simply shouldn't break in under three years. That is silly. Maybe I'm one of the unlucky few. Maybe most PS4's keep working well into their teens like the PS2 did. But having this experience makes me want to not even bother with a PS5.
If you put any console with a fan at the back of it in an area with no venting then it'll break.
The console will break if you do this, so that is why Bandorr is saying it sounds like you do not understand the difference between a manufacturing fault and doing something like putting the system into water, one of those is never the fault of the manufacturer unless the product is a pair of speedos
His question about controllers....
Does it connect to other DS4's? Have you tried borrowing a friends and connecting that, would the price of a new DS4 not be cheaper than sending it back if it's just your controller that is broken and not the system.
Regarding not wanting to buy a PS5 because your mate broke your PS4 for you.... Have no idea what to say to that. If someone drove your car into a wall would it put you off that brand of vehicle?
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
