Hi, Is there any “warranty void if removed” sticker inside the iPhone 4S or any other way for Apple to determine it ? I need to replace the display assembly for a friend and he doesn’t want to void its warranty. Thanks

Yes and no. If you mean the “Do Not Remove” sticker, no. Apple is using the water sensors as warranty seals on this model. There’s one screw hidden under a water sensor in this model, and it’s supposed to act as a hint the phone was opened or water damaged.

Not even a good answer. There is. When you remove the glass back from the iphone 4’s, there is a screw with a sticker over the top of one of the heads. When removed, your warranty is void. To remove the screen assembly, you have to remove the back and those screws. Good luck!

yes the water indicator is how we tell if the iphone has been taken down to replace a screen as well as if it has had major moisture inside. personally i replace with the same sticker. make sure you use the correct tools for the screws & good luck. allow up to about 1.5 hours the first time you replace a screen then for I4 or I4S then when you do it in about half an hour u are good enough to tell the world.

We are speaking of a Iphone 4s. GSM or CDMA they were all made exactly the same, All components and stickers match. There is no LQDM damage dot on any screw in the 4S Model of the Iphone. Only phone with a LQDM dot on the screw was the Iphone 4 ATT GSM. The tape under the rear camera will peal of easily so you can place it back on. I have repaired countless iphone 4s’s and that sticker is no void indicator. They are not placed on exactly the same way on each matching device. Your warranty void would be the breaking of the seal of the back cover. That’s all it would take. Pentalobe screws are placed in at a specific torque in specific ways. If you sent a phone back to apple if you open the back cover and put it back on they would be able to tell. As far as going to your local Phone shop with a phone under warranty after you dabbled around on the inside for a bit, as long as the liquid damage triggers are not red in the headset jack and or the System connector plug in, you would be fine.
