The good folks over at iFixit have been ripping apart a Samsung Galaxy S9 and a Samsung Galaxy S9 Plus, revealing a few hidden secrets about the new flagship phones. For a start, if you're planning on repairing these phones yourself at home, you've got a tough challenge on your hands.

Both phones get a repairability score of 4 out of 10, with 10 meaning an easy repair. The special Infinity Display glass on the S9 and S9 Plus makes it particularly hard to get these devices opened up and put back together again without something breaking, iFixit says.
