Introduction: Fix Scratches on Your Ceramic Finger Print Sensor
After using my Oneplus 3 phone for like a year and 1/2 , i started noticing a layer of scratch on my finger print sensor. The sensitivity of the sensor had come down like around 20% from the initial purchase, its just that at times you have to try twice to unlock your phone. I Tried cleaning with damp cloth and nothing worked. Also i noticed few blogs to clean scratched glasses using toothpaste. So i geared up few thing lying around and tried fixing the scratch and voila it worked flawlessly. while in middle i thought of making this task as an instructable and here we are...
My first Instructable :)
Step 1: Things Needed and Process
so things needed should be fairly simple.
- An Ear bud
- A cutter
- A toy motor and powered with a battery
- tooth paste (i used sensodyne )
- your victim . (scratched finger print sensor)
cut the earbud into half and try to snub it on the shaft of the toy motor. Damp the earbud and take a mustard size of toothpaste and apply it on the scratched parts of the finger print sensor.
Now power the motor with battery and buff out the toothpaste. keep repeating and wipe using a clean cloth. At one point of time you will start realizing that the glossy finish of the finger print will start shining out.
Step 2: Old Phone Turned New
i got my new phone back after 1.5 years. The finger Print sensor is back as brand new. And i feel that the sensitivity has increased a bit and nothing worst with the working of it. like it if this helped.
