iFixit says that the Samsung Galaxy S7 is even tougher to repair than its predecessor
iFixit gave the Samsung Galaxy S7 a repairability score of 3 out of 10 points. That's a whole point lower than the repairability score that iFixit noted the Galaxy S6 with, and obviously a terrible score overall.
As the teardown experts note, the battery of the smartphone can be removed without taking out the motherboard first, unlike how battery replacements went on the Galaxy S6. Unfortunately, the battery is still pretty well glued in place, making replacement a difficult undertaking overall.
Another repairability impediment is that the USB port cannot be replaced without taking down the display first. Worse still, the display is prone to damage when removed. Even taking a look inside the handset poses its challenge in the form of a strong adhesive on the rear glass panel.
This new teardown gives us another look at the cooling heat pipe that Samsung refers to as liquid cooling, although as iFixit notes, it's really more of a "copper twig".
