life expectancy Does Fingerprint Sensor have Life Expectancy?

[Mr.Stork]

I have a Fingerprint Sensor on my phone and I primarily use it to turn my phone on and it's a good alternative to the power button as the power button can get bricked or stuck after many times of use, happened with my last phone. But can the finger print sensor get broken after repeated use just like the physical buttons?

 

I don't mash my fingers on it or anything, it's on the back of my phone and my phone is 3 months old, and I press on it gently like touching the screen. So do I expect it to break at some point in a few years? (I understand that every electronics get broken, I'm asking if it'll die sooner than the phone itself)

 

My phone is Vivo Y19. (Not pro)

I don't think anyone ever tested that out, but for regular large readers it would be 5-10 years.

Rear mounted fingerprint sensors are all based on capacitive touchscreens, which are basically super precise versions of the touchscreen on the front of your phone. In other words, you can expect it to wear out at the same rate, and likely slower since you use it less, that your touchscreen wears out, and I haven't seen a touchscreen wear out since the days of resistive screens like the ones on the Nintendo DS. Basically barring an impact, drop or otherwise, that breaks something I wouldn't expect it to stop working any time soon.

If your phone get dropped then it's hard to say the lifespan of your phone in the first hand. Further, every electronic component including any type of sensor has a finite lifetime. But, FP sensors are robust and they are designed to live longer than the phone it's attached with.

So, the lifespan of FP sensor cover a greater area and thet includes many if and buts. If the health of your phone is good then surely the FP is healthy too whch do not have any loose and moving parts.

As long as it's not heavily scratched (and I mean "deeper groves at a level 7" scratched), you've nothing to worry about. Battery will give out years before the fingerprint scanner will. 

 

The guy who bought a Samsung galaxy S8 off me last year says it's working as new (the fingerprint scanner), and it's been the main way to unlock the phone from day one. If you need reassurance

Do I need to keep it clean too? I mean what can I clean it with?

No moving parts

No fragile parts or high susceptibility to damage

IDK what you are worrying about...

Cuz it's sounds (and is) too good, because buttons gets damaged and it is a good alternative which as you said is also durable! I tend to doubt too goo things

They're sealed units, clean it with whatever you want. It will be fine as long as you aren't soaking your phone in a strong acid for hours.

Thanks for the answer!
