Why We Tell Every Customer to Use Genuine Back Glass on an iPhoneiPhone 15 Pro Back Glass Replacement: the customer brought an aftermarket part, and here's what we told him — Downtown Los Angeles
An iPhone 15 Pro with a shattered back came across the counter, along with a replacement panel the customer had bought himself. It was an aftermarket part, and the phone had already been through one back glass replacement before this. We give every back glass customer the same advice: go genuine, new or used. This time the customer chose his own part, and we fitted it for $60 in labor. The choice is his to make. Our job is to explain clearly why we recommend what we do, and then do the work properly.
The back glass fitted in an earlier repair cracked again, from the camera down to the bottom edge.
Aftermarket back glass supplied by the customer. Coil and flash transferred, bonded, tested. $60 labor.
Genuine new is $159 plus tax for the part. Genuine used is $200 all in. Why, below.

| Tech's note | Anyone who brings in a back glass hears the same thing from me: go genuine. The durability gap between aftermarket and genuine glass is real. Aftermarket panels often crack from a drop that a genuine panel would shrug off, and then you're paying for the repair twice, sometimes three times. A little more now, done once, is cheaper in the end. I say it every time. The catch is the price. A genuine new back glass for the 15 Pro is $159 for the part alone, close to $180 with tax. Add even a minimum $60 for labor and you're at $240, which is the price of a decent used phone. So what we actually recommend is a genuine used back glass. Pulled from genuine devices, nearly scratch-free, the same glass and the same adhesive structure as new. That gets the whole job done for $200. This customer heard all of that and decided to go with the part he'd already bought. That's his call, and we respect it. What doesn't change is the work: the frame gets cleaned properly, the coil gets moved without a crease, the adhesive goes on evenly, and everything gets tested before it leaves. |
Which back glass, and what it really costs
Exactly what we explain at the counter. Two things matter: price and how it holds up.
Cheapest, and first to break
It looks identical. What's different is the glass thickness, the tempering and the adhesive. Light drops crack it. If you bring your own, we'll fit it for $60 in labor — but if it breaks again, you've paid twice.
What we recommend
A back glass pulled from a genuine device. We only use ones with next to no scratches, so it's hard to tell from new, and the glass strength and adhesive structure are the same as a new genuine part. $200 including labor. Genuine durability at a realistic price.
The surest, and the priciest
$159 for the part, about $180 with tax, around $240 with labor. If you're keeping the phone for years or want it flawless, this is the one. For most people, genuine used gives the same durability for less.
Three frames from the bench
Under an hour of work, photographed as we went.
Removing the cracked panel
On the iPhone 15 Pro the rear glass is only bonded to the frame, so we heat the adhesive and lift the whole panel off. Because it's already shattered, we stabilize the face first so fragments don't drop inside. This design is why the job takes under an hour: no laser grinding like older models needed.
Cleaning the frame
Every trace of old adhesive and glass comes off the frame. That's what lets the new panel sit flat and stay down afterward. This step is the same whatever part is going in. Uneven adhesive will lift a genuine panel just as surely as an aftermarket one.
Transferring the coil and flash, then bonding
The MagSafe wireless-charging coil and the flash flex are stuck to the inside of the back glass, so they come off the old panel and onto the new one. A single crease in the coil kills wireless charging, which makes this the most careful step of the job. Then the customer's panel is bonded to the frame and pressed while it sets, with cameras, flash and wireless charging checked along the way.
An hour later
The customer's glass, fitted our way.
Cameras, flash and MagSafe all normal
All three cameras, the flash, MagSafe magnet alignment and wireless charging were checked before hand-off. A back glass replacement doesn't touch storage, so photos, contacts and apps are exactly as they were. The panel is seated clean with no lift at the edges. How well it survives the next drop is the part that's out of our hands.
The questions that usually follow
Straight answers, as always.
How long does an iPhone 15 Pro back glass replacement take?
About 30 minutes to an hour. The 15 Pro's rear glass is only bonded to the frame, so it comes off without a laser and the job is done while you wait.
How much does it cost?
Genuine used back glass is $200 including labor. Genuine new is $159 for the part, about $180 with tax, around $240 with labor. If you bring your own part, labor is $60.
Can I bring my own part?
Yes, and we'll fit it for $60 in labor. We can't warranty the quality or durability of a part we didn't supply, and we'll tell you up front that aftermarket glass tends to crack again.
What condition is a genuine used back glass in?
We use only panels from genuine devices with next to no scratches. They're hard to tell from new, and the glass strength and adhesive structure are identical to a new genuine part.
Why don't you recommend aftermarket back glass?
The durability gap is real. It often cracks from a light drop, so a cheap repair now tends to become two or three repairs later. The phone in this post had already been through one replacement.
Can a cracked back glass break wireless charging?
It can. The MagSafe coil is bonded to the inside of the glass and sometimes gets damaged along with it. We check it while moving it to the new panel and tell you if it's damaged.
Will I lose my data?
No. A back glass replacement never touches storage. Photos, messages, apps and accounts stay exactly where they are.
