Phone repair, in store
I dropped it in the car park on a Tuesday morning and had written the phone off in my head by lunchtime. They took it in, quoted me on the spot and handed it back the same afternoon with the old panel in a bag so I could see what had actually broken.
Alicia R.
iPhone 14 Pro screen repair
It was down to twenty percent before lunch every single day and I assumed I was being sold a new battery whatever I said. They tested it in front of me first, showed me the health reading, then swapped it and had me out inside the hour.
Tomas G.
Galaxy S23 battery replacement
I put a full cup of coffee across the keyboard and had four years of work on there with no backup. They opened it the same day, cleaned the board properly rather than just drying it out, and every key on it still works months later.
Priya N.
MacBook Air liquid damage
The last place I used quoted one number on the phone and a different one at the counter. These people looked at the port, told me what it would cost before they touched anything, and that was exactly what I paid when I collected it.
Kevin M.
iPad 10th generation charging port
The back was shattered end to end and pieces of it were coming away in my hand. I left it with them on my lunch break, came back after work, and there is no seam and no gap anywhere on it. You would not know it had happened.
Samuel O.
Pixel 8 back glass repair
What actually decided it for me was the 90 day malfunction warranty, because I had been burned by a cheap repair before that failed inside a fortnight. Nothing has gone wrong with this one, but I would have had somewhere to go if it had.

Why CELLTECH
Why Choose CELLTECH for Android Repair?
Android devices come from different manufacturers and can use very different displays, batteries, charging connections, cameras, frames, and internal components. That means two Android devices showing the same symptom may require completely different repairs. CELLTECH starts with the exact device model and symptoms before recommending a repair. At CELLTECH:
- Your Android device can be inspected before repair is recommended.
- Screen, battery, charging, camera, back glass, and liquid related problems can be checked.
- The exact manufacturer and model are considered.
- Repair options and pricing are explained before work begins.
- Parts availability can be checked for your device.
- Walk-ins are welcome.
- Every repair happens at a staffed CELLTECH counter rather than by mail-in.
- The goal is to identify the actual problem, avoid unnecessary replacement of working components, and get your Android device back into use as quickly as the repair allows.
A cracked Android screen can involve more than damaged outer glass. You may notice:
Cracked front glass, Black areas, Green or pink lines, Display flickering, Touch not responding, Ghost touches, Dark patches, Image distortion, Part of the screen remaining black, Complete image loss
Different Android devices use different display technologies and screen assemblies.
The appropriate repair therefore depends on the exact model and which part of the display has been damaged.
A display can still show a normal image while touch stops responding correctly. Possible symptoms include:
Dead touch areas, Delayed response, Swipes not registering, Typing problems
Touch working only on part of the display
Random or unintended touches
Before assuming screen replacement is necessary, restart the device and check whether a screen protector or software problem may be contributing.
If the issue remains, the display and touch system should be inspected.
A black display does not automatically mean the entire device has stopped working. You may still notice that the device:
Rings, Vibrates, Makes notification sounds, Responds to charging, Connects to another device
The problem may involve the screen, display connection, battery, power system, or another component.
If possible, restart the device first.
If the display remains black, have the device inspected before screen replacement is recommended.
Persistent vertical or horizontal lines can indicate a display related problem. You may notice:
Green line, Pink line, White line, Purple line, Multiple colored lines, Display distortion around the line
Restart the device and install available Android system updates first.
If the line remains across different apps and screens, the display may need inspection.
If display replacement is appropriate, CELLTECH can confirm:
Replacement screen availability, Expected turnaround
Display technology
OLED and AMOLED Android Screen Problems
Many Android devices use OLED or AMOLED display technology. These displays can develop problems such as:
- Colored lines
- Black areas
- Dead pixels
- Uneven brightness
- Image retention
- Permanent burn-in
- Flickering
A temporary display issue does not always mean replacement is required.
If the problem remains after restarting the device and checking available updates, inspection can help determine whether the display hardware is affected.
Battery
Android Battery Replacement
Rechargeable batteries gradually lose performance as they age. Possible signs of an Android battery problem include:
- Battery draining much faster than before
- Device needing frequent charging
- Unexpected shutdowns
- Battery percentage falling quickly
Device only working while connected to power
- Charging taking unusually long
- Device becoming unusually warm
A battery symptom does not automatically mean battery replacement is required.
Battery performance can also be affected by:
- Apps
- Screen brightness
- Background activity
- Software
- Mobile network conditions
- Device temperature
- Charging behavior
- Other hardware problems
If battery performance remains unusually poor during normal use, CELLTECH can inspect the device and explain the available battery replacement options.
If your device shuts down shortly after being disconnected from power, the battery may be one possible cause. However, power related hardware or charging problems can sometimes create similar symptoms. The device should be inspected before battery replacement is confirmed. If the battery is identified as the problem, CELLTECH can check:
Battery availability, Repair price
A battery indicator that falls sharply or behaves inconsistently may be associated with battery condition or battery reporting. If this happens repeatedly together with poor battery life or unexpected shutdowns, have the device checked.
Charging
Android Device Does Not Charge
An Android device that does not charge does not automatically need a new battery or charging port. Possible causes include:
- Damaged USB cable
- Faulty power adapter
- Debris inside the charging connection
- USB-C port damage
- Moisture
- Battery problem
- Charging related hardware
- Another internal component
Try another compatible cable and power adapter if available.
If charging continues to fail, the charging system should be inspected.
Most current Android devices use USB-C charging connections. Possible symptoms include:
Device not charging, Charging slowly, Cable feeling loose, Charging only at certain angles, Charging repeatedly disconnecting, Computer not detecting the device, Accessories not connecting correctly
A damaged USB-C port is only one possible cause.
Cable problems, debris, moisture, battery condition, and other hardware should also be considered.
If charging starts only when the cable is pushed or held in a certain position, possible causes include:
Damaged cable connector, Debris inside the USB-C port, Port wear, Loose connection, Physical charging port damage
Avoid repeatedly forcing the cable into position.
Have the charging connection inspected if the problem continues.
Some Android devices can detect moisture around the USB-C charging connection and temporarily prevent wired charging. If a moisture warning appears:
Disconnect the charging cable.
Do not force wired charging.
Allow the charging connection to dry.
Do not insert objects into the USB-C port.
Avoid excessive external heat.
If the warning remains after the charging connection is completely dry, or wired charging still does not work, the device may need inspection.
Cameras
Android Camera Repair
Modern Android devices may use multiple front and rear cameras. Possible camera problems include:
- Blurry photos
- Camera unable to focus
- Black camera preview
- Shaking image
- Front camera failure
- Rear camera failure
- Cracked camera lens glass
- Camera app freezing
One camera working while another does not
The outer camera glass and camera module can be separate components.
An inspection helps determine whether the problem involves the camera glass, camera hardware, software, or another component.
Focus problems can be caused by:
Dirty camera glass, Damaged camera lens cover, Autofocus hardware, Impact damage, Camera protector interference, Software, Another camera component
Clean the outside camera glass and temporarily remove any camera protector that may be interfering.
If focus problems remain, have the camera system inspected.
A camera preview that shakes while the device is held still can indicate a problem involving focus or stabilization hardware. This can sometimes happen after a physical impact. The exact camera component should be identified before replacement is recommended.
Back glass
Android Back Glass Repair
Many Android devices use glass or glass-like rear panels. A hard impact can cause:
- Cracked rear glass
- Shattered back panel
- Missing pieces
- Sharp edges
- Damage around cameras
- Rear panel separation
- Frame damage
Rear construction varies by manufacturer and model.
The available back glass repair depends on the exact Android device and replacement component.
Liquid damage
Water or Liquid Damaged Android Device
Liquid exposure can affect several components at the same time. Possible symptoms include:
- Device not turning on
- Charging problems
- Moisture warning
- Black screen
- Touch problems
- Battery drain
- Camera condensation
- Speaker problems
- Microphone problems
- Unexpected shutdowns
If the device or charging connection is wet, avoid wired charging until the connection has dried.
Do not put the device in rice.
Liquid related problems should begin with diagnosis because the visible symptom may not be the only damage.
A 20 minute repair should not automatically be expected for complex liquid damage.
Overheating
Android Device Overheating
Android devices can become warm during gaming, video recording, navigation, charging, software updates, and other demanding tasks. However, persistent or excessive heat during normal use should be checked. Possible causes can include:
- Heavy application activity
- Battery problems
- Charging issues
- Software
- Internal hardware
- Environmental temperature
If the device becomes excessively hot or appears physically swollen, stop using it and arrange professional inspection.
No power
Android Device Does Not Turn On
A device that does not power on should not automatically be treated as a battery repair. Possible causes can involve:
- Battery
- Charging system
- Display
- Power related hardware
- Software
- Another internal component
Look for:
Vibrations, Notification sounds, Charging sounds, Display backlight, Connection to another device
If the Android device appears to be operating but the screen remains black, the display may be one possible cause.
If there is no response at all, broader diagnosis may be necessary.
Once the cause is identified, CELLTECH can explain:
Repair option, Parts availability, Expected turnaround
Google Pixel

Pixel display problems can include:
Cracked glass, Flickering, Green tint, Vertical or horizontal lines, Dead pixels, Black display, Touch problems
Restarting the device and installing available system updates can help rule out certain software issues.
Persistent physical or display problems may require hardware inspection.
Supported Pixel generations can provide battery diagnostic information within Android. Battery behavior should be considered together with:
Battery life, Charging performance, Unexpected shutdowns, Device temperature, Actual everyday usage
If the battery is performing poorly, CELLTECH can inspect the device and explain available repair options.
A Pixel that does not charge or power on can have a problem involving:
Charger, USB-C cable, Charging port, Battery, Screen, Power related hardware
The device should be diagnosed before one component is assumed to be faulty.

Find your model
How Do I Find My Android Model?
Knowing the exact model helps identify compatible repair parts. Model information is usually available within the device Settings when the display is working. Depending on the Android manufacturer, look for an area such as: Settings → About Device or Settings → About. The exact menu wording can vary by manufacturer and Android version. If you cannot access Settings, bring the device to CELLTECH and the model can be identified.
How it works
How a CELLTECH Android Repair Works
1. Tell Us What Happened
Tell us what the Android device is doing: a drop, fast battery drain, charging that stopped, a blurry camera, or liquid exposure. The make and model matter here as much as the symptom does.
2. We Inspect the Device
We check the visible damage and the functions tied to the fault. Android hardware varies widely between manufacturers, so the exact model is confirmed before any replacement part is named.
3. We Explain the Repair and Quote
You get the part type, the repair cost, and the related features worth testing afterward, with the expected turnaround and the warranty terms explained before you approve the work.
4. You Decide
You decide whether to go ahead. Work begins only after the available Android repair and its price have been explained, and there is no charge for the inspection itself.
Pricing
How Much Does Android Repair Cost?
There is no single repair price that applies to every Android device. Cost depends on several factors.
Different Android manufacturers use different displays, batteries, cameras, charging systems, and internal designs. The exact manufacturer and model are needed to identify compatible parts.
Screen replacement, battery replacement, charging port repair, camera repair, back glass repair, and liquid damage service involve different components and amounts of work.
Android devices can use different display technologies, including LCD, OLED, and AMOLED. Replacement display pricing can therefore vary significantly. The display technology can also affect parts availability and turnaround.
Some devices require more disassembly to reach a damaged component. Device construction can affect:
Repair time, Labor, Disassembly required
One impact may affect several parts, including:
Screen, Frame, Back glass, Camera, Charging system, Other internal components
Additional damage can affect both repair cost and repair time.
Current, older, and less common Android models can have very different replacement parts availability. Parts availability can also determine whether the repair:
Requires additional ordering time
CELLTECH provides a quote after confirming the device and required repair.
Turnaround
How Long Does Android Repair Take?
You may not need to spend the entire day without your Android device. Many common CELLTECH Android repairs can be completed in as little as 20 minutes when the correct replacement component is available and no additional damage is found. Same day Android repair is also available for many supported devices and services. Android repair time depends on:
- Manufacturer
- Exact model
- Repair required
- Parts availability
- Device construction
- Extent of damage
- Number of affected components
- Additional diagnosis required
Common screen, battery, camera, and charging repairs can be among the faster services on supported models.
Liquid damage, complex devices, uncommon parts, or multiple component damage can require additional time.
Your CELLTECH store can provide a more accurate estimate after confirming your exact device and repair.
Repair or replace
Should I Repair or Replace My Android Device?
A cracked screen, worn battery, charging problem, or damaged camera does not automatically mean you need a new device. Repair may make sense when:
- The rest of the device works well.
- One major component is damaged.
- Required parts are available.
- Repair cost is reasonable compared with replacement.
- The device still meets your needs.
- You want to keep your existing device.
Repair can also help you avoid buying, transferring data to, and setting up another device because of one repairable hardware issue.
- Replacement may make more sense when:
Several major components are damaged.
Internal damage is extensive.
Parts are difficult to obtain.
Repair cost approaches replacement cost.
The device no longer meets your needs.
A repair quote gives you a realistic number to compare with replacing the device.
Before your visit
Before You Bring Your Android Device In
If your device still works normally, maintain a current backup of important:
Photos, Videos, Contacts, Messages, Documents, Authentication information, Other files
Many hardware repairs do not normally require personal data to be removed, but maintaining a backup before repair is recommended.
Device access may help test repaired functions after service. Depending on the repair, testing can include:
Display, Touch, Charging, Battery, Cameras, Fingerprint recognition, Face recognition, Other relevant features
The exact Android model helps check repair and parts availability. It can also help determine:
Repair price, Replacement component, Parts availability
If the issue involves charging, bringing the cable and adapter you normally use may provide useful diagnostic information. This can help distinguish accessory problems from device problems.
Tell the technician if the problem began after moisture or liquid exposure. Liquid can affect more than one component.
Previous screen, battery, charging, camera, or internal repair information can be useful during inspection.
If getting your device back quickly is important, ask whether the required component is currently in stock for your model. Turnaround depends on it more than on anything else.
After the repair
What Should You Test After Android Repair?
Depending on the repair, relevant checks can include:
- Display image
- Touch across the screen
- Brightness
- Colors
- Charging
- Battery behavior
- Front camera
- Rear cameras
- Camera focus
- Speakers
- Microphone
- Volume buttons
- Wi-Fi
- Bluetooth
- Fingerprint recognition where applicable
- Face recognition where applicable
- Wireless charging where applicable
- Other functions related to the repair
If something does not behave correctly, mention it before leaving the store.
Water resistance
Water Resistance After Android Repair
Some Android devices have manufacturer rated resistance to water and dust. The exact rating varies by device. Water resistance is also not permanent and can decrease because of:
- Normal wear
- Physical damage
- Cracked glass
- Frame damage
- Previous repairs
- Device disassembly
- Seal deterioration
If repair requires opening the device, ask what sealing or reassembly process applies.
Do not automatically assume that a repaired device has exactly the same water resistance it had when new.
The 90 day malfunction warranty applies to covered repair related malfunctions and does not mean the device is protected against new liquid exposure.
CELLTECH Android repairs are backed by a 90 day malfunction warranty. This gives you added confidence after your repair. If the repaired or replaced component develops a covered malfunction during the 90 day malfunction warranty period, bring your Android device and repair information back to CELLTECH so the issue can be reviewed according to the applicable warranty terms. The 90 day malfunction warranty applies to qualifying repair related malfunctions. New accidental damage, physical impact, cracked glass caused by another incident, new liquid exposure, misuse, or unrelated device problems may be treated separately. Before approving service, you can ask:
- What does the 90 day malfunction warranty cover?
- Which replacement component is covered?
- Is applicable repair related labor covered?
- What problems are excluded?
- Is new accidental damage excluded?
- Is new liquid exposure excluded?
- How is warranty service requested?
- Can warranty service be handled at another CELLTECH location?
- Keep your repair receipt and related information after service.
