Replacing Broken Screen Glass




About: I am 28 years old engineering student from Oulu in Finland. I make these projects as a hobby. My goal is to make these instructables at the lowest cost possible making these projects to be done by everyone....

Repairing a broken screen glass can be very expensive project to do. Finding a dealer that will change the glass is not a problem, but the price they charge is just really too much for the work and the spare parts. Here is how to do that on your own and making it cost a fraction of the price AND mostly it can be done in under 15 minutes.

The phone used to demonstrate this is my wife's Nokia Lumia 625. The screen in this one cracks very easily. My 3 year old son dropped it on the floor from about a 30 cm height and it just cracked. The main reason to this is that the glass goes over the phones plastic edge so nothing is protecting the glass.

First thing first.

Where do i get a replacement glass for the phone? Here in Finland the screen replacement(with work done) costs 144 euros and the price just for the glass is 44 euros. Well that's not cheap in any way for compared to the price of the phone (was about 195 euros when bought).

Well, i think it's time to check out what eBay has to offer..

I found it... The exact same glass sold in here for 44 euros costs in eBay 9 euros and that is cheap. Just make sure when ordering a replacement that it's the exactly the same part.

Okay. Now we have the spare glass.

There is not really much tools that you will need. You will need a screwdriver (the ordered glass had one for free inside!!) and a 100% plastic playing card or something that is as thin.

Step 1: Disassemble the Phone

The screwdriver was not the only free item in the box. It also had that blue plastic flap. I don't remember the name for it but it is used in disassembling for plastic parts since it wont leave any marks.

Taking apart the phone is in this case is very easy. Just remove the back plate and then take the screws off.

After that use the plastic flap to pry the phone open. Search for a small "holes" in the sides and push the flap in there. It will crack open. Then remove the battery and the touch screen cable. Remember the position of the cable for easy remove of the glass. Mostly it's on top of the phone.

Step 2: Remove the Broken Glass

This is the hardest part. Do this wrong and you wont get a picture ever in your phone.

If you have and TFT or LCD screen in your phone the risk is not big. BUT if your phone has got an LED display like AMOLED or any other type of LED screen be very careful. If an LED display is touched with any force it will brake.

The glass is attached to the phone with two side tape from the side of the screen. Remove this and the screen will fall out.

To remove the tape and separating the glass from the phone can be done with plastic playing card. Yes, you heard me right. The playing card is thin enough to fit between the phone and the glass and its hard enough to cut the tape in there. Start by inserting the card in the lower corner of the phone and start pushing it inside.

Most safe method in this is when you have the one corner free put the playing card sideways and start swinging it in. Work your way up as you feel the tape is giving up.

I used only one playing card to remove this glass it's good to have few spare in the reach.

Step 3: Insert New Glass

Well done! The screen is now off and the phone is waiting a new one. Remove as much old tape as you can from the sides of the phone so the new glass will fit on the phone neatly.

First remove the inner protection film from the glass. Remember that removing this will also remove the film from the tape in the new glass.

Push the glass touch screen cable trough the phone before pushing the glass on the phone.

Put the cable in the correct place and insert the battery on the phone( in this Nokia the battery is inside the phone).

Test the phone that it still works.

Step 4: Assemble the Phone

Assembling the phone is just the reverse as before. Put the screws back in and hope for the best.

The phone works fine and the glass is smooth AND most importantly the touch screen works like a charm.

All this for a price of 9 euros.

    There is always a change to damage your phone when you disassemble it.

    Take your time and don't rush things and you should be okay.

    Hello, if I want to replace the LCD of the phone (LG Optimus G E975), how can I heat it? The glass I could put in an owen, but the whole phone without battery also?

    Thank you for your answer in advance!

    Hi! Do not put your phone in owen. If you have a owen that can precisely heat up to 50'C that is okay. Remove any part that can be removed from the phone. Get your self a thin and sharp thing (like the playing card for example) and a suction cup.

    If you don't have a owen. Place suction cup on the screen and start heating it up with a hair dryer. Pull the class out of the phone and remove any excess glue and tape. Do not touch the actual screen with anything.

    I am a cellphone tek and I would like to mention homemade jobs like this don't often work 100% or last very long, the reason? the factory your phone is produced in and the service centers that repair it use UV glue to bond the touch to the LCD/LED screen. hopefully you find this a helpful tip, to maintain your touch and lasting work =3

    Great 'ible. I've fixed a couple of phone screens (iphone and nexus 4) and I'd say be really careful as in both my fixes the phones have lost their ability to detect proximity. I was careful in both instances but the sensor is incredibly fragile. In both cases I had to heat the screens (hairdryer) in order to melt the glue that holds them on. I wonder if this step might have affected the sensors.

    Thanks! The heat is not good for the phone in any way. Using the playing card does the same thing that heat does to the glue on the tape. Most safely method to use heat in removing tape is to heat an oven in to about 50'C (but not more than...) and let the phone heat up in there (whitout battery of course) and then use suction cup to remove the glass while it's still hot. The playing card "cuts" the tape whitout heating the phone and the outcome is still the same. AMOLED screens don't stand the heat and if the heat is too much (ie using hairdryer whitout monitoring the heat on the area) the AMOLED screen will take some damage. Proximity sensors can be fragile but i don't think that the heat would react to it so much if not aplying directly to it for several seconds. Proximity sensors are "meant" to take a lot of G-force in order to work in any case meant to work.

    Awesome fix, good to know these are fixable, otherwise I would definitely be someone that is held hostage by the tech repair guys. You should definitely enter into our Fix It contest. Thanks for sharing!

    Thank you for commentin! Phones are pretty much always fixable but most of the repair shops won't do any of these "hard" fixes. Such as chancing the USB connector witch is in some phones too fragile to handle "real" life. I have done few of these and i think that i should make an 'ible out of that too :D
