Samsung Galaxy S5 / S5 Mini Display Glass Replacement

Before you start

This repair guide will show you step-by-step how to use your newly purchased iTG display glass repair set to repair your Samsung Galaxy S5 smartphone. It is compatible with models SM-G900F, G901F and G903F (i9600, i9601, and i9603).

As the repair procedure is essentially the same, this guide can also be used with our repair set for the Samsung Galaxy S5 Mini smartphone. It is compatible with model SM-G800F.

Please make sure all the parts of the supplied repair set are included. If you find that there is something missing or damaged, please contact us before proceeding.

You Will Need
  • The iTG repair set for the correct model smartphone.
  • Heat gun / hair dryer / our UFiX Heat Bag (available here) or other way to heat the display glass.
  • EVOBOND Debonder (glue remover) / WD40 / isopropyl alcohol and a lint-free cloth.
  • Lens cleaner / glass cleaner.
  • Patience (usual repair time: 1 – 2hrs but can take longer depending on how cracked the glass is).
You May Also Need
  • Infrared thermometer (available here).
  • Suction Cup Pliers (available here).
  • Clear packaging tape / sellotape.
  • Tweezers.
  • Rubber gloves.
  • LOCA UV liquid glue and a UV light source, if attempting the glue bonding procedure. (These can be purchased together here as part of our iTG® PROFI Smartphone Display Glass Gluing Set).

We now included an iTG® metal opening tool and PVC seperator cards with every smartphone repair set that we sell. These tools are to be used in place of the plastic pick tools and playing cards mentioned in the following guide.


In addition we would like to recommend our optional new, ultra thin, flexible spring steel opening tool for seperating the display glass from the smartphone digitizer. While it is perfectly possible to complete the repair successfully using the included PVC cards, our opening tool is specially designed to be easy to handle, being thinner and therefore reducing the chance of causing damage to the digitizer while attempting to seperate the display glass. For more information or to make a purchase, please view our Amazon page here.

Let’s Begin!
Step 1

Using the blue pry tool, remove the back cover.

Insert the tool along the edge of the phone between the frame and back case. Then slide it along the edge to separate the two parts. It should un-clip and come off very easily.

Step 2

Using the same tool, remove the battery.

Step 3

Remove both the SIM card and microSD memory card if present. To do this, pull the card gently with your fingernail and slide it out.

The following steps require lots of patience. Be careful and take your time!
Step 4

Using your selected heating method (such as our UFiX Heat Bag), heat the surface of the display glass to approximately 80-90°C. This melts the glue that holds the glass to the display. This will loosen the glue but should not damage the electronics.

If you have one available, use an infrared thermometer (recommended) to check the temperature. If you don’t have a thermometer, heat the glass until you can no longer touch it with your bare finger.

When using a heat gun, hold the gun at least 5 cm from your phone (in the picture it looks closer). With the heat gun set to low, heat the glass for about 3 to 5 minutes (depends on the strength of your heat gun). When using a hairdryer it will take longer.

You must be careful when applying heat. If the display is heated up too much it may melt the digitizer and cause discoloration. It is however important to heat the glue sufficiently so that the glass can be separated without applying excessive force. If you start to see any discoloration then shut off the gun IMMEDIATELY. When using an infrared thermometer you should be able to avoid this.

Step 5

Using the supplied pick tools or pry tools, very carefully start to work at the edges to separate the glass. A thin flexible tool is useful to first insert under the edge of the glass to start the procedure. Make sure to work from the top of the phone to the bottom.

Leave the tools in place as you go, in order to keep the glass separated from the glue. You will need to keep reapplying heat to the glass approximately every 30 seconds for around 1-2 minutes while you work, as the glass will cool down quickly. For glass which is heavily damaged you will need to be extra careful not to damage the LCD with the shattered glass pieces.

Be careful along the bottom edge of the screen as the 2 touch keys and home button are glued to the glass. Leave these until last if possible. (They need to be detached before the glass screen is removed.)

Step 6

Once you have separated the edges of the glass, work your way in towards the centre, reapplying heat as needed.

iTech Tip! Old playing cards / business cards are useful here to work into the glue and separate the glass. Just make sure the material they are made from is flexible and won’t damage the digitizer.

Again work from top to bottom and keep reapplying heat as required. If needed you can use the supplied suction cup tool to pull up slightly on the glass as you work to separate it.

Step 7

Once you think the glass is completely separated, don’t immediately try to remove the whole piece! The 2 touch buttons and home button at the bottom of the screen must first be detached.

Carefully pull the screen from the top, opening it like a book. You should now be able to see the touch buttons.

With a plastic pry tool, carefully detach the buttons from the inner side of the glass. A little heat may be necessary.

Step 8

Remove the broken display glass.

If the display glass is very shattered you may need to pick out the small pieces with a pair of tweezers one-by-one. This will take extra time. (You can now also check if the display still works.)

Step 9

Remove any adhesive tape that is left stuck around the edge of the screen. For this it is helpful to use a pair of tweezers.

To remove any leftover glue from the digitizer, apply a small amount of cleaning liquid and wipe with a lint-free cloth. (We recommend using special glue remover such as EVOBOND Debonder, but a small amount of WD40 applied to the cloth also works well. Just don’t use too much). You can then scrape off the loosened glue with your finger or a pick tool, just don’t press too hard.

iTech Tip! A piece of packaging tape folded back on itself (sticky side out) is useful here to dab onto the screen and remove any small loose spots of glue.  Just make sure you don’t press too hard on the digitizer.

When cleaning off the glue, do NOT attempt to scrape glue out of the cracks between the digitizer and the frame. A very small amount of force towards the centre or from underneath will crack the display.

Step 10

Remove any leftover smudges from the digitizer using lens cleaning wipes or glass cleaner and a clean lint-free cloth. Try not to leave any fluff or dust on the display as it will be trapped in once the new display glass is fitted. Make sure the home and touch buttons are pressed back down into place.

At this point you can apply the LOCA UV liquid glue if you wish. It is not essential and we do not recommend it for this repair (see our disclaimer). However if you would like to attempt it, you can follow our guide here.
Step 11

Now you need to apply the 3M pre-cut adhesive sheet included with your repair set to the glass. Lay the sheet on a clean, flat, dust free surface and remove the large clear plastic protective layer so that the adhesive remains fixed to the coloured plastic.

Now peel back and remove the protective clear plastic from the back of the new display glass. Be careful not to touch the display part of the glass as you do this as it can leave marks or smudges (wear rubber gloves if possible). Lay the glass down onto the adhesive face up, so that it lines up with the edges of the glass. It should fit perfectly.

Make sure the adhesive is pressed down firmly enough so that when you peel back the coloured protective layer, the adhesive stays glued to the glass.

There should be a small piece of the coloured plastic that is still attached to the adhesive. Peel this back and remove it.


It is now finally time to install your new display glass!

Carefully move the glass into position above the frame of the phone. Start by fixing the bottom edge of the glass, making sure that the touch buttons and home button are correctly positioned.

Lower the glass down into position and press into place. Make sure it is properly fixed all the way round and is lying flush with the frame. You can now remove the top layer of protective plastic from the glass.

Step 13

Reinstall the SIM card and microSD card and refit the battery (the reverse of the removal procedure).

Reinstall the back cover and clip it back into place. You can now switch your phone back on and make sure it is all working correctly.

Step 14

Now pat yourself on the back for a job well done 🙂
