I’ve worked in a repair shop before, and we would actually do similar with specific devices. The difference with us I guess is that we wouldn’t take it for repair without you consenting to that prior to us even checking in the device. For things like the original Microsoft Surfaces, and some Lenovo laptops, they’re glued together so tightly that opening them up to fix something is basically impossible without breaking the screen that is on it.

Also with us if we took it for repair and couldn’t fix it, it either had to come back in the same condition, or we fronted the bill for a replacement.

None of this applies to phones at all though. I’d be really interested to hear what device was so difficult that they couldn’t repair it, because all current gen Samsung, Apple and Google Pixel devices are definitely repairable, as long as you have the proper software tools.
