Xiaomi Touchscreen Not Working — Causes & Fixes (2026)
Fix an unresponsive or erratic touchscreen on Xiaomi, Redmi and POCO phones running MIUI 14 or HyperOS.
Problem overview
A Xiaomi touchscreen that stops responding, registers ghost touches, or works only in patches is one of the more disruptive faults because it can make navigating Settings to troubleshoot difficult in itself. On MIUI and HyperOS devices, the touch layer sits between the physical digitiser and the software gesture system, and a fault can originate at either end: a software glitch after an update, a screen protector or case interfering with touch sensitivity, or a genuine digitiser hardware failure following a drop or liquid exposure.
Software-side causes are more common than users expect. MIUI's gesture navigation system, including the side-swipe-back gesture and the floating "Quick ball" assistive touch, occasionally conflicts with certain apps running in full-screen or immersive mode, producing areas of the screen that seem unresponsive when they're actually being intercepted by a system gesture zone. A stuck or frozen app can also make the whole screen appear unresponsive when in fact only the foreground app has hung, which a forced restart (holding the power button for 10-15 seconds) will usually reveal.
Physical interference is the next most common cause and is worth ruling out before assuming a fault. Cheap tempered-glass screen protectors, especially ones applied with trapped air bubbles or covering the edges of curved-edge displays, can reduce touch sensitivity noticeably, and wet or greasy fingers, or using the phone in the rain without an IP-rated model, will also cause missed or erratic touches. Gloves not designed for capacitive screens will not register at all unless MIUI's Glove mode is enabled under Settings > Display > Touch settings on supported models.
A genuinely faulty digitiser typically shows itself through consistent, reproducible symptoms: a specific area of the screen that never registers touch regardless of what's on screen, touches registering in the wrong location, or the screen responding erratically even with the phone in Safe mode and no case or protector fitted. This pattern strongly suggests physical damage to the digitiser layer itself, often following a drop, a cracked screen, or moisture ingress, and it will not be resolved by any settings change or software update.
Distinguishing a software fault from hardware damage is done most reliably with Xiaomi's built-in touchscreen diagnostic, accessible via dial code *#*#2664#*#* on most MIUI and HyperOS builds, which draws a grid over the screen and highlights exactly which zones respond to touch, making a hardware fault immediately visible rather than something you have to infer from app behaviour.
Possible causes
Frozen or crashed foreground app
An app that has stopped responding can make the entire screen appear unresponsive even though the underlying touch hardware is working fine; a force-restart usually resolves this immediately.
Screen protector or case interference
Poorly fitted tempered glass, trapped air bubbles, or a case overlapping the curved edge of the display can noticeably reduce or block touch sensitivity, particularly near the screen edges.
Wet, greasy or gloved fingers
Capacitive touchscreens require a small electrical charge transfer to register a touch, so water, oil, or standard gloves prevent reliable detection unless MIUI's Glove mode is specifically enabled.
MIUI gesture navigation conflicts
The side-swipe-back gesture zones and floating Quick ball assistive touch can occasionally intercept touches near screen edges in certain full-screen apps, making those areas feel unresponsive when only a gesture zone is misbehaving.
Software bug after a MIUI/HyperOS update
A regression in the touch-input driver following a system update can cause intermittent unresponsiveness or ghost touches across many users of the same model until Xiaomi issues a patch.
Physical drop or impact damage
Even without visible cracking, an impact can separate or damage the digitiser layer beneath the glass, causing a specific zone of the screen to stop registering touch permanently.
Liquid ingress
Moisture reaching the digitiser or its connector, even from humidity or light splashing on non-IP-rated older Redmi/POCO models, can cause erratic ghost touches or complete unresponsiveness.
Loose display connector after a previous repair
If the screen has been replaced or opened before, a loose or partially seated digitiser ribbon cable can cause intermittent touch failure that worsens with flexing or temperature changes.
Quick checks
- Force-restart the phone by holding the power button for 10-15 seconds.
- Remove any screen protector and case and retest touch response.
- Dry and clean the screen and your fingers, then retest.
- Boot into Safe mode to check whether a third-party app is causing the issue.
- Check whether unresponsiveness is limited to one specific screen area.
- Check for a pending MIUI/HyperOS update under Settings > About phone > System updates.
- Note whether the issue started right after a drop, spill, or previous repair.
- Test whether the touchscreen works normally in the CIT/touch diagnostic tool.

Step-by-step solutions
1. Force-restart the device
Hold the power button (and volume down on some models) for 10-15 seconds to force a restart, which clears a hung foreground app or a temporary graphics-driver glitch that can make the whole screen appear frozen.
2. Remove case and screen protector
Take off any case and screen protector entirely and retest touch response directly on the glass; if sensitivity returns to normal, replace the protector with a thinner, properly fitted one designed specifically for your model.
3. Clean the screen and dry your hands
Wipe the display with a dry microfibre cloth to remove moisture, oil or dust, and ensure your fingers are dry; retest touch response afterwards, especially if the issue appeared after being outdoors or handling the phone with wet hands.
4. Boot into Safe mode to rule out a third-party app
Press and hold the power button, then long-press 'Power off' until prompted to reboot into Safe mode, which disables all third-party apps. If touch behaves normally in Safe mode, a recently installed app is the cause and should be uninstalled individually to identify it.
5. Disable gesture navigation temporarily
Go to Settings > Additional settings > Full screen display > Full screen gestures and switch to classic three-button navigation to rule out a gesture-zone conflict, particularly if the unresponsive area is near the very edge of the screen.
6. Run the built-in touchscreen diagnostic
Dial *#*#2664#*#* to launch Xiaomi's touch test grid, which draws a coloured overlay across the display; swipe across every zone and check whether any section fails to register or shows a gap, which pinpoints a hardware fault immediately.
7. Update MIUI/HyperOS and check for known issues
Go to Settings > About phone > System updates and install any pending patch, since Xiaomi periodically fixes touch-driver regressions; search Xiaomi's community forum for your model number if the issue matches a known widely reported bug.
8. Factory reset or seek hardware repair if the fault is reproducible
If the CIT touch test consistently shows a specific unresponsive zone regardless of app or protector, back up your data and have the digitiser inspected professionally, since a localised, reproducible dead zone on the diagnostic grid indicates physical damage rather than a software fault.
When to seek repair
If the CIT touchscreen test shows a consistent, reproducible dead zone regardless of case, protector or software state, or if the fault began immediately after a drop or liquid exposure, the digitiser has very likely failed physically and needs professional screen replacement rather than further software troubleshooting. Continue using an alternative input method (a connected mouse via USB-C or Bluetooth accessibility features) only as a temporary measure until repaired.

Frequently asked questions
- Why does my Xiaomi screen sometimes register touches I didn't make?
- Ghost touches are usually caused by moisture, a damaged screen protector, a charging cable interfering with the digitiser's electrical field, or in more serious cases a failing digitiser layer following impact damage; testing with the charger unplugged and the protector removed helps isolate which.
- Does *#*#2664#*#* work on all Xiaomi phones?
- It works on most MIUI 14 and HyperOS devices as Xiaomi's standard touchscreen diagnostic, though a small number of newer HyperOS builds have moved diagnostic access into the Settings search bar instead — if the code doesn't respond, search Settings for 'touch test' or 'CIT'.
- Can a software update actually break my touchscreen?
- Yes, a touch-driver regression introduced in a system update can cause intermittent unresponsiveness or reduced sensitivity across an entire model line, and this is usually confirmed by widespread reports on Xiaomi's community forums shortly after the update rolls out.
- Why does only the edge of my screen not respond?
- This is most often caused by curved-edge screen protectors that don't sit flush, or by MIUI's gesture navigation zones intercepting edge swipes; it can also indicate a digitiser fault if it persists with the protector removed and gestures switched to button navigation.
- Is it safe to keep using a phone with a partially unresponsive touchscreen?
- It's safe from a device-damage perspective but inconvenient and potentially a sign of worsening digitiser damage, particularly following a drop; if the affected area is expanding over time, get it inspected promptly rather than waiting for it to fail completely.
- Will a factory reset fix ghost touches?
- It will fix ghost touches caused by a corrupted app or software conflict, but it will not fix ghost touches caused by moisture ingress or physical digitiser damage, which will reappear immediately after reset in those cases.
- Does Xiaomi's Glove mode fix all touch sensitivity issues?
- No, Glove mode only increases sensitivity to register touches through thin gloves or with slightly damp fingers; it will not restore function to a physically damaged digitiser and can occasionally make ghost touches slightly worse if enabled unnecessarily.
