It might be tempting to get a new phone if you smash the back on your Galaxy S7. But it’s a lot cheaper to just replace the glass yourself.
Glass-backed phones are inherently more fragile than their plastic or metal-backed counterparts. Glass is more slippery, phones are more prone to just slide off surfaces, and while metal or plastic will chip, glass will crack and shatter.
That’s exactly what happened to my Samsung Galaxy S7, and while the Galaxy S8 is here and the Galaxy S9 won’t be too far away, the S7 is still a very good phone worth saving.
Replacing the front glass is a different story, but if all that’s wrong with your phone is some shattering on the back, you can fix it yourself relatively quickly and very cheaply.
It’s also worth pointing out that any kind of self-repair is probably going to affect the phone’s water resistance. So don’t go dunking it afterwards.
What you’ll need
Obviously, the first thing you need is a new back. These aren’t particularly expensive, and I got mine from Amazon for about £20 ($26). This also included a basic tool kit, which includes some small screwdrivers, a suction cup, and some plastic pry tools. You may or may not need to use these as you’ll see later on.
When choosing a back, also make sure to choose one with adhesive pre-applied. Because otherwise you’ll have to do this yourself and it’s honestly not something you should have to deal with. They’re no more expensive with adhesive, just be sure to choose the right one.
It’s also worth noting that there will be a bunch out there that aren’t the exact Samsung replacement parts. The one I linked above is the same exact back I used in this guide and while the black color match is perfect, it
