In my 2 decades of using smartphones I had to replace the screen once (out ow my own stupidity of thinking I could balance everything from one room to another, which I could not, and my phone kissed the tiled floor).

The replacement, including a new screen, cost me €80 and took two days. It was carried out at an official partner store of my phone manufacturer. That's perfectly fine, considering how convenient it is to have someone else do the work for me.
