Is the display the same for the 4 and 4s?

"The connectors are the same for the digitizer and LCD and the screen will function properly between the models but the parts are physically different and will not fit either way. The sensor layout is also different which would cause the phone to not work properly. The home button is also different.

In short, you can't do it."

"I have been replacing iphone screens for a couple years now. 3G 3GS 4 and 4S.

I have had to substitute a 4 for a 4S and vice versa a couple times. Of course, it is best to use the proper model whenever possible, but here's a trick if you absolutely have to use the wrong screen [and therefore the wrong bezel].

Chopping off the brackets can be very hard to do unless you have the right sort of metal cutter / industrial scissors.

Instead, you can carefully remove the bezel from both the cracked (original) screen and the new screen and reattach the original bezel to the new screen.

A couple things to be careful of:

If you pull too hard on the bezel, you will snap it / crack it. Not the end of the world (you can still use it), but be slow and deliberate when pulling away from the screen/LCD.

Also, if you pull too hard and with too much force, you might crack the LCD and have the dreaded bleeding ink drip look negating your whole endeavor.

Carefully start by pulling on a corner with your thumb pushing the screen away and your fingers pulling toward you on a corner bracket.

Make sure you pull the sticky tape along with the bezel and keep it in place as you go (it will try to pull away). This is extremely important as that sticky tape is the ONLY thing holding the screen to the rest of the body.

This is a drastic step, but it does work.

I know I have replaced 4 screens with 4S without a problem. I can't say with confidence that it works the other way around.

If you're getting white lines running through your LCD, you've probably bought a cheap part.

It's best to buy a part (ebay, for example) that is held by a warehouse distributor in the USA. This ensures that you can track the part, hold someone accountable and usually expect a more timely delivery.

If you order the part from Hong Kong, you're ordering from a black hole. Not to say that it won't work, but you're taking a little more of a chance.

Also, DON'T BE CHEAP! Spend the extra $10-20 bucks and get yourself a nice screen. Don't just buy the one that's the best deal.

both are the same ( same connectors ) only the bezel is different, but you can take out the 4s bezel and put it around the 4G bezel ...

As far as i know, iphone 4 4s lcd screen are not the same.

"Anna, Yes they are. I've physically tested an assembly from an iPhone 4 to my 4S and it works.

ALL you need to do is replace the plastic bezel so it fits.

One thing I did not test was the light sensor to see if it was compatible, but i will do that soon!"

"I just installed an iPhone 4s screen assembly on an iPhone 4 and it worked perfectly, I tested the ambient sensor during a call and it worked fine too.

What I had to do is to remove the two legs at the top and the legs on both sides (I tried to cut the legs but in the end I removed the whole metal thing). The I could use the bottom legs and put the screws."
