Introduction

Use this guide to replace a broken screen on your Nokia G22.

This guide is written for the genuine Nokia G22 screen assembly. The assembly consists of the screen and midframe together in one part. It's possible to replace just the screen, but that requires a separate procedure. Make sure you have the right part before you begin this repair.

Note: This procedure requires you to transfer all of your phone's internals to the new screen.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Step 1

Insert a SIM eject tool, bit, or a straightened paper clip into the small hole on the SIM card tray on the upper left edge of the phone.
Press firmly to eject the tray.

Step 2

Remove the SIM card tray.
When installing either a SIM card or a microSD card, make sure they're in the correct orientation and sitting completely flush with the edges of the tray before reinserting the tray into the phone.

Step 3

The back cover of the phone is held in place by plastic clips.
Insert an opening pick under the small notch in the SIM card tray slot.

Step 4

Position the opening pick at a steep downward angle between the back cover and the screen assembly.
Slide the opening pick down the left edge of the phone to release the plastic clips.

Step 5

Turn the opening pick around the corner and continue to slide it along the bottom edge to release the plastic clips.

Step 6

Slide the opening pick up the right edge to continue releasing the plastic clips.

Step 7

Slide the opening pick along the top edge to release the remaining plastic clips.
Don't try to fully remove the back cover just yet, as it's still connected to the phone.

Step 8

With the phone laying screen-side down, carefully lift the right edge of the back cover, opening it like a book.
Take care not to strain or tear the attached fingerprint reader cable during this procedure.
Lay the back cover next to the phone.

Step 9

Use a Phillips screwdriver to remove the 3.8 mm‑long screw securing the fingerprint reader bracket.

Step 10

Use a pair of tweezers or your fingers to remove the fingerprint reader bracket.
Take care not to puncture the battery with your tool—a punctured or bent battery may leak dangerous chemicals or cause a fire.
During reassembly, make sure to align the fingerprint reader bracket correctly and push the small metal edge back into its recess under the motherboard cover.

Step 11

Use the flat end of a spudger to disconnect the fingerprint reader by prying the connector straight up from its socket.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.
Remove the back cover.

Step 12

There is a white sticker covering one of the top screws. Pierce through it with the screwdriver or use tweezers to remove it.
Use a Phillips screwdriver to remove the eleven 3.8 mm-long screws securing the motherboard cover.

Step 13

The motherboard cover is further held in place by plastic clips.
Insert an opening pick under the right edge of the motherboard cover to release its plastic clips.
Flip the motherboard cover over the top edge of the phone.

Step 14

The motherboard cover has two short adhesive tapes wrapped around the top edge and onto the frame.
Pull the motherboard cover away from the frame to separate the adhesive tape and remove it.
During reassembly, fold the adhesive strips onto the frame after snapping the motherboard cover back in place.

Step 15

Use the flat end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.

Step 16

There is a white sticker covering one of the top screws. Pierce through it with the screwdriver or use tweezers to remove it.
Use a Phillips screwdriver to remove the eight 3.8 mm-long screws securing the loudspeaker.

Step 17

Insert an opening pick underneath the right edge of the loudspeaker.
Twist the opening pick to release loudspeaker from the plastic clips holding it in place.

Step 18

Use your fingers or a pair of tweezers to remove the loudspeaker.

Step 19

Use the flat end of a spudger to disconnect the display cable by prying the connector straight up from its socket.

Step 20

Use the pointed end of a spudger to disconnect the antenna cable by prying the connector straight up from its socket on the motherboard.

Step 21

Use a pair of tweezers or your fingers to lift the antenna cable out of its recess in the frame.
During reassembly, connect the antenna cable to the motherboard before reseating the antenna cable into its recess.

Step 22

Use a Phillips screwdriver to remove the 2.8 mm‑long screw securing the charging port assembly.

Step 23

Insert the flat end of a spudger underneath the top edge of the charging port assembly.
Pry up the charging port assembly by twisting the spudger until you can grip it with your fingers.

Step 24

Remove the charging port assembly.

Müsste hier nicht noch das (Antennen?-)Kabel von der Ladeanschluss-Baugruppe getrennt werden? In Schritt 25 ist es bereits entfernt, wird aber nicht erwähnt.

Hallo Haebbaerrt, danke für deine Anmerkung! Die Ladeanschluss-Baugruppe wird beim Tausch der Displayeinheit übertragen. Wir empfehlen, das Kabel mit der Ladeanschluss-Baugruppe verbunden zu lassen, da dies die Positionierung des Kabels beim Wiedereinbau erleichtert.

Step 25

The vibration motor is held in place with mild adhesive.
Insert the pointed end of a spudger into the small recess on the upper right side of the vibration motor.
Pivot the spudger up to pry up the vibration motor off of the adhesive securing it underneath.
Use a pair of tweezers or your fingers to remove the vibration motor.
During reassembly, you can reuse the old adhesive if it's still sticky. If not, replace it with new custom cut adhesive, such as Tesa Tape.

Step 26

Use the flat end of a spudger to disconnect the display cable by prying the connector up from its socket.

Step 27

Use a Phillips screwdriver to remove the 2.8 mm‑long screw securing the motherboard.

Step 28

Insert the pointed end of a spudger underneath the top right corner of the motherboard.
Pry the motherboard up until you can grip it with your fingers.

Step 29

Remove the motherboard.
During reassembly apply small beads of thermal paste to the marked areas on the new screen assembly. See this generic guide for detailed steps on how to prepare the motherboard and apply the paste.

Step 30

The power and volume button cable is secured to the frame with mild adhesive.
Insert one arm of a pair of tweezers underneath the small indent on the button cable.
Lift up with the tweezers to separate the connector from the frame.

Step 31

The power and volume button cable is secured to the frame with mild adhesive.
Use a pair of tweezers to gently peel the power and volume button cable away from the edge of the frame to remove it.
During reassembly, make sure to align the power and volume button cable with the notches in the frame.

Step 32

The earpiece speaker is secured to the frame with mild adhesive.
Insert the flat end of a spudger underneath the bottom left corner of the earpiece speaker and pry it out of its recess.
Remove the earpiece speaker.
During reassembly, make sure the gold contact springs on the earpiece speaker are facing up and closer to the bottom edge of the phone before readhering it to the frame.

Step 33

If your new screen assembly comes with a camera bracket you can skip this step. If not you’ll need to remove the bracket for transfer.
Use a pair of tweezers to remove the black camera bracket.
The camera bracket is held in place with mild adhesive.
During reassembly, make sure to install the camera bracket on the new screen assembly in the correct orientation and press it down lightly. Use adhesive tape if necessary.

Step 34

If your new screen assembly comes with a foam pad you can skip this step. If not you’ll need to remove the pad for transfer.
Use a pair of tweezers to carefully peel the foam off of the frame to remove it.
The foam pad in the camera recess is held in place with mild adhesive.
During reassembly, install the foam pad on the new screen assembly by lightly pressing it down. Use adhesive tape if necessary.

Step 35

Be extra careful to not puncture, bend, or deform the battery during the next few steps—a damaged battery may leak dangerous chemicals or cause a fire.
Use your fingers to peel the two outer adhesive tabs off of the battery.

Step 36

The battery in the Nokia G22 is secured with adhesive. A pull tab is provided to separate the adhesive and remove the battery.
Use your fingers to peel the center green pull tab off of the battery.
Using one hand to hold the phone down, use your other hand to slowly and steadily lift the center green pull tab up to separate the adhesive securing the battery underneath.
If the green pull tab should rip, you can use the outer tabs to pull out the battery including the adhesive film underneath. Be aware that therefore this will take more time and probably some heat to soften the adhesive.
If you have any difficulties with stubborn battery adhesive, you can contact "Nokia phones support".

Step 37

Peel the battery off of the adhesive film and remove it.

Step 38

Grab the bottom right edge of the leftover adhesive film.
Pull the film towards the top of the phone with steady force to remove it.
To reinstall the battery into the new screen assembly:
Reattach the adhesive film to the battery.
Align the bottom edge of the battery (the edge without adhesive) with the bottom edge of the recess.
Lower the battery down and press firmly to secure it in place.

Step 39

Only the screen assembly remains.
Compare your new replacement assembly to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
If you're reusing your original battery, carefully inspect it for any signs of physical damage. If it's bent, creased, dented or scratched, replace it with a new battery. Installing a damaged battery is a safety hazard.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
