A broken Poco F1 display is usually fixed by replacing the LCD and touch digitiser assembly as one unit. The glass, touch layer and LCD panel are bonded together, so a cracked front glass, lines across the picture, black patches or dead touch zones all mean the whole assembly should be replaced. The part costs far less than a new phone, and the repair is a manageable DIY job for someone careful: you open the back, disconnect the battery and display, then heat and lift the old screen from the front. If the picture is faulty but the glass is perfect and the problem comes and goes when you press or flex the phone, a display flex cable may be the cause instead. This guide helps you diagnose the fault, choose the right part and fit it safely.
About the Poco F1 display
The Poco F1 (sold in some markets as the Pocophone F1) launched in 2018 with a 6.18-inch IPS LCD with a notch, a Full HD+ resolution and a Snapdragon 845 chip, as summarised in the Wikipedia entry for the Pocophone F1. Because it uses an LCD rather than an OLED panel, replacement screens are relatively affordable, and an LCD replacement behaves in the same way as the panel the phone shipped with. The Wikipedia overview of liquid-crystal displays explains how the backlight and panel work, which helps when diagnosing faults.
Diagnose the fault first
| Symptom | Likely cause | Part needed |
|---|---|---|
| Cracked front glass, display works | Damaged glass layer | LCD screen assembly (glass is bonded to the LCD) |
| Lines, ink spots or black patches | Damaged LCD panel after an impact | LCD screen assembly |
| Touch dead in areas or phantom touches | Damaged digitiser | LCD screen assembly |
| Black screen, phone rings and vibrates | Failed LCD, backlight or disconnected display flex | Check connector first; usually the LCD assembly |
| Picture flickers or vanishes when the phone is squeezed, glass intact | Loose connector or damaged display flex cable | Reseat connector; replace the LCD flex if it persists |
| New screen fitted but still no picture | Damaged board-to-LCD flex or connector | Main board to LCD flex cable |
| Phone will not turn on or charge at all | Battery, charging or board fault, not the display | Diagnose power first |
Quick checks before buying parts
- Force restart: hold the power button for 10 to 15 seconds. A frozen phone can look like a dead screen.
- Call the phone: if it rings and vibrates while the screen stays black, the phone is alive and the fault is display-related.
- Look at the screen with a torch in a dark room. A very faint image means the LCD works but the backlight has failed, which still points to the LCD assembly.
- Connect to a computer: if the phone is detected, your data is likely intact. Back it up if you can.

LCD screen replacement (most repairs)
Our For Xiaomi POCO F1 LCD Screen Replacement (£14.21) is an LCD and touch digitiser assembly made for the Poco F1. According to the listing, it is a direct swap for cracked screens, lines across the picture, a screen that will not light up or a touch layer that has stopped responding.
Flex cables (for connection faults)
If your glass and LCD are undamaged but the picture cuts out, or a new screen still shows nothing, the cable that links the display to the main board may be torn or damaged. We stock two Poco F1 flex parts:
- For Xiaomi Poco F1 LCD Flex Cable: £2.51.
- For Xiaomi Poco F1 Main Board to LCD Flex Cable: £2.33.
These are cheap, but they are a less common fix than the screen itself. Inspect the existing cable for creases, tears and burnt or corroded contacts before ordering, and compare it with the product photos so you buy the matching cable.
You can see every spare for this model in our Xiaomi Poco F1 parts collection.
What does a Poco F1 screen repair cost?
For a DIY repair, your main cost is the screen assembly listed above, plus any tools and adhesive you do not already own. A repair shop will add labour to the part price; labour rates vary by shop and region, so ask for a quote that separates parts and labour. Because the Poco F1 is now several years old, compare the total repair cost with the value of the phone: for most owners with a working phone apart from the screen, a self-fitted LCD is the most economical option.
We do not quote prices from Xiaomi or other stores here, because availability of factory parts for a 2018 phone varies and prices change. If you see a part described as from the Mi store, check that it is actually in stock and compare like for like: an LCD with digitiser versus one that also includes the frame.
Tools and materials
- A heat source: heat mat, hairdryer or heat gun used on low.
- Suction cup, thin plastic opening picks and a plastic spudger.
- Small Phillips screwdriver for the internal screws.
- Tweezers.
- Adhesive for the back cover and the screen (for example B-7000 style adhesive or pre-cut adhesive), and isopropyl alcohol for cleaning old glue.
- Safety glasses and gloves for handling broken glass.
Our repair tools collection covers the opening tools and drivers you need.
How to replace the Poco F1 screen
Back up the phone if you can and power it off. Cover cracked glass with packing tape to keep shards together.
- Remove the SIM tray.
- Remove the back cover: warm the edges of the back, then insert an opening pick at the bottom edge and work it around the sides to release the clips and adhesive. Go gently near the fingerprint sensor, which connects to the board by a short flex.
- Disconnect the fingerprint flex if it is attached, and set the back cover aside.
- Remove the screws holding the mid-frame or shield over the main board, and lift it away. Keep screws in order; they may differ in length.
- Disconnect the battery first, then the display connector.
- Heat the front of the screen evenly around the edges to soften the adhesive.
- Lift the old screen from the front: use a suction cup and picks to separate it from the frame, working slowly around the edges. If the glass is badly cracked, work in sections and keep tape on it.
- Feed the display flex out through the slot in the frame as the screen comes away.
- Clean the frame: remove old adhesive and glass fragments, then wipe with isopropyl alcohol. A clean, flat frame is essential for the new screen to sit flush.
- Test the new screen before gluing: feed its flex through the frame, connect it, reconnect the battery and power on. Check the picture, brightness and touch across the whole screen, including the corners.
- Glue the new screen: power off and disconnect the battery, apply a thin, even bead of adhesive or fit pre-cut adhesive, then press the screen into place. Clamp or tape it lightly while the adhesive cures, following the adhesive's instructions.
- Reassemble: reconnect the display and battery, refit the shield and screws, reconnect the fingerprint flex, and refit the back cover with fresh adhesive.
Take care at the top of the phone, where the earpiece, front camera and sensors sit close to the screen edge.
After the repair
- Check the proximity sensor: make a call and hold the phone to your ear; the screen should switch off.
- Check auto-brightness: cover the top of the phone and watch the brightness change.
- Check the fingerprint sensor and re-enrol your fingerprints if needed.
- Fit a screen protector once the adhesive has cured. See our screen protectors.
- Treat water resistance as reduced. The Poco F1 was not sold as water resistant, and any repair adds further risk, so keep it away from water.
Preventing another broken screen
Once the new display is fitted, a few simple habits reduce the chance of repeating the repair:
- Use a tempered glass screen protector. It takes the first impact and is far cheaper to replace than an LCD.
- Use a case with a raised lip around the screen, so the glass does not touch the ground when the phone lands face down.
- Avoid back pockets. Sitting on a phone flexes the frame and can crack an LCD from behind, even without a drop.
- Keep keys and coins separate from the phone in bags and pockets.
- Let the adhesive cure fully before heavy use; a screen that lifts at the edge is easier to crack.
Common mistakes
- Not disconnecting the battery before unplugging the display. This can damage the new screen or the board.
- Prying too deep and cutting the display flex or damaging the frame.
- Overheating: too much heat can damage the LCD, the battery and plastic parts.
- Skipping the test fit: always test the new screen before gluing.
- Too much adhesive: excess glue can seep onto the display or stop the screen sitting flat.
- Leaving glass shards in the frame, which create pressure points and can crack the new screen.
- Tearing the fingerprint flex when removing the back cover.
DIY or repair shop?
If you are comfortable with small screws and patience, this is a realistic first or second phone repair. If you have never opened a phone and the phone holds data you cannot back up, a local repair shop may be safer. Either way, buying the part yourself lets you check its specification before fitting. If you also maintain other Xiaomi phones, our wider Xiaomi parts range and Redmi parts range cover many models.
Recycling the old screen
Broken screens and old phones are electrical waste and should not go in household bins. Take them to a local recycling centre or a retailer take-back point; you can find options through Recycle Your Electricals. Wrap broken glass securely first.
Frequently asked questions
Can I replace only the glass on a Poco F1?
Not practically. The glass is bonded to the LCD and touch layer, so separating them needs specialist equipment and risks damaging the panel. Replacing the full LCD assembly is the reliable fix.
How much does a Poco F1 screen replacement cost?
For DIY, the main cost is the screen assembly (£14.21 on our store when checked) plus adhesive and any tools you need. Shops add labour, which varies.
My Poco F1 screen is black but the phone rings. What is wrong?
Most often the LCD or its backlight has failed after an impact. Check the display connector is seated; if it is, replace the screen assembly.
Is the replacement screen LCD or AMOLED?
The Poco F1 uses an LCD, and our replacement is an LCD with the touch digitiser included.
Do I need the flex cable as well as the screen?
Usually not. Only order a flex cable if the existing one is torn or damaged, or a new screen still shows no picture.
Will my data be lost?
Replacing the screen does not erase data. Back up anyway, because accidents during repairs can happen.
Is the Poco F1 worth repairing?
If the rest of the phone works well and the battery is healthy, a self-fitted screen is a low-cost way to keep it going.
The bottom line
A cracked or faulty Poco F1 display is almost always fixed by replacing the LCD and touch assembly, which you can fit yourself with basic tools, heat, adhesive and care. Check the phone still rings, back up your data, order the screen, test it before gluing, and you can have the phone working again for the price of the part. Only order a flex cable if the cable itself is damaged. Start with the screen below.
