Is there any "warranty void" sticker in iPhone 4S?
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.
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.
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.
