Used smartphones are one of the most popular items bought and sold in Kegalle — and one of the easiest categories to get burned on. Sellers do not always disclose problems, and some problems are invisible until it is too late. Run through this checklist before handing over any money.
1. Check the IMEI Status
The IMEI (International Mobile Equipment Identity) is a unique 15-digit code assigned to every phone. Dial *#06# to see it on screen, then check it against the box (if available). Most importantly, verify it is not blacklisted:
- Go to imei.info and enter the number
- Or use the Sri Lanka Telecom IMEI check service
A blacklisted IMEI means the phone was reported stolen or has unpaid finance — it will not connect to any local network.
2. Test Every Function
Do not skip this because the seller is watching. Test methodically:
- Screen: Open a white image and look for dead pixels, yellow patches, or burn-in
- Touch: Draw a line across the full screen in all directions
- Cameras: Take a photo in good light and check for blur or discolouration
- Speakers & microphone: Make a test call or play a video
- Charging port: Plug in a cable and confirm it charges
- Wi-Fi, Bluetooth, GPS: Enable each and test briefly
- Face ID / fingerprint: Enrol and test
3. Check the Battery Health
On iPhone, go to Settings → Battery → Battery Health. Anything below 80% means the battery will need replacing soon (LKR 5,000–15,000 depending on model). On Android, use the dialer code *#*#4636#*#* on Samsung devices, or download an app like AccuBattery to check the capacity.
4. Look for Water Damage
Most phones have a Liquid Contact Indicator inside the SIM tray slot — it shows as a small white or silver dot that turns red/pink if the phone has been exposed to water. Use a torch and look inside the SIM slot. On iPhones this is visible without tools; on many Androids you may need to remove the SIM tray.
5. Factory Reset It Before You Pay
Ask the seller to factory reset the phone in front of you — or do it yourself — before payment. This confirms the seller actually owns the device (a stolen phone may be locked to the original owner’s Apple ID or Google Account after a reset, making it a useless brick). If the seller refuses a factory reset, walk away.
