How To Make Your Android Phone’s Fingerprint Scanner More Accurate

How To Make Your Android Phone's Fingerprint Scanner More Accurate 1
Fingerprint scanners, those little round things you see on the back of every smartphone these days can be quite annoying once in a while when you try unlocking your phone with them and you get messages like this

“Fingerprint Mismatch, Fingerprint Error, Fingerprint Is Dirty, FingerPrint Not Recognized”.

that’ll probably leave you staring at you fingers and wonder what’s wrong with your fingerprint, most times I’d just use the Face ID to bypass it but if you don’t have that I’ll walk you through on how to increase the accuracy of your fingerprint scanner.

Depending on your Android phone model, you may have to look around a little bit to find the exact name of the fingerprint setting. On Pixel phones, it’s called Pixel Imprint. On Samsung Galaxy devices, it’s just labeled as “Fingerprint Scanner. So just head over to your settings and go to security.

Most smartphones would let you put up to 5 fingers. The best way to set this up is in an ambidextrous way, don’t go wild and call 4 of your family members and register their fingerprint along with you.(Of course I’m just teasing) or put all the fingers on your one hand as a print there.

You should register fingers on both hands. This way, if the hand you usually unlock your phone with is tied up, you can still unlock your phone easily with the other one. Similarly, it’s probably a good idea to register multiple fingers on each hand. I believe we all use our phones in a way that our index finger is the easiest to unlock it (unless you’re an alien) so if you are right-handed you can try this

a. Right Index Finger
b. Right Middle Finger
c. Left Index Finger

If you are a south-paw just do the exact opposite. Right now we have 2 more finger print slots left.
this time get your fingers wet and clean it in a way that it isn’t totally dry then register the finger. This will come in handy when you are in the bathroom or coming out of the rest room and your hands are a bit damp. so we have

d.Wet Finger

So one more finger is remaining ay..now the moment of truth you can register your toe print as the one; anyone of your choice .I know right now you probably think I’m nuts for saying this, you’d be shocked at what you find.

e. Your Toe

On a side note – The whorls and ridges on our toes and fingers develop uniquely in each person and are not genetically determined. There are a few famous cases in which criminals have been caught by using toe-prints. The first was at a Scottish bakery in 1952 when a safe-cracker was identified by the footprints he left in flour.

Tecno Camon i4 – Full Specs And Cheapest Price

Published

on

Tecno Camon i4

Tecno just launched a new device into the Camon lineup the Tecno Camon i4 and the device comes with very impressive specifications and a very good price in this post I’ll be looking at the specs of the Tecno Camon i4.

Tecno Camon i4

The TECNO CAMON i4 ships with a mid-range MediaTek Helio A22 processor for the 2GB / 3GB RAM version and a MediaTek Helio P22 processor for the 4GB RAM version and 32GB / 64GB  of internal storage.

The Camon i4 runs on Android 9.0 with HiOS 4.6 on top, keeping the lights on is a 3500mAh battery with support for fast charging.

I do hope the fast charging isn’t the same as the Xcharge on the Tecno Spark 2 because that means it’s not actually fast charge. Tecno deserves this shirt on that note

Design And Display

I’m quite impressed with the fact that Tecno decided to go with the dewdrop notch on this device instead of that lousy Apple-like rectangular notch. This one is quite similar to the one on the Samsung M20 and I’d say it’s not bad at all considering the fact that they’ve been giving us phones with notches since the release of the Camon 11 Pro.

You basically get a 6.2-inch IPS Capacitive display with an 81.3% screen-to-body ratio. It’s not something you would call totally bezelless as there’s still as small chin below the device.

Camera 

The Camera is one of the selling points of this device as the smartphone’s triple camera has a 13MP, 8MP, and 2MP lens combination, which means you would get an impressive performance while taking photos and recording videos at 1080p. The secondary camera at the front is a 16-MP lens and great for selfies. You also get better quality when calling someone via video so cheers to the Snapchat and Instagram Slay Queens.

Software And Hardware

In the specifications department, I’ll give Tecno a B+ on this. The Camon i4 comes with a MediaTek Helio A22 chipset clocked at 2-GHz combined with a Cortex A53 quad-core processor, which takes charge of the Camon i4’s performance. In the graphics department, you get A PowerVR GE8300 GPU to take care of the graphics. There’s also a 4GB variant that comes with a higher Helio P22 Chipset.

Storage

The Camon i4 comes with 32GB of internal storage that can be expanded to 256GB via a memory card. There are 2GB, 3GB, and 4GB variants.

How Multiple Cameras Work On Android And iOS Smartphones

How Multiple Cameras Work On Android And iOS Smartphones 16

How multiple cameras work on smartphones have always been a question on the minds of most people and 2019 is the year of multiple cameras and many if not all smartphone brands have released phones with multiple cameras. You’ve probably seen the Nokia 9 Pureview with 5 cameras and the Huawei P30 Pro that comes with 4 cameras  (40MP + 20MP +12MP +TOF Camera) and 50x optical zoom.

How Multiple Cameras Work

These two devices come with crazy specifications but I won’t go into that right now, maybe in another post.

However, have you ever tried covering the main camera of your device with a dual camera?

If you haven’t, try doing that right now.

You’ll notice you are actually blocking the whole camera. That leaves the question – What do the secondary cameras do and how do they work.

How Multiple Cameras Work

Now I want you to understand this. Most OEMs have other uses of their secondary camera other than the ones I’m going to mention below. These are just the basic functions of the secondary camera.

The secondary camera improves the overall clarity of the image with the help of a “Monochrome” feature. The secondary camera only records the black and white version of the image. With the help of the Monochrome sensor, the primary camera measures how much light is coming from the point of focus.

Previously (with the exception of the Google Pixel 3), the primary camera in smartphones normally handled the measurement so there was a very high possibility of losing some detail while measuring light intensity since it would still need to work on the color filtering.

So this extra burden is handled by the second camera which takes care of that area. Combining the monochrome image which has detailed information about the light and sharpness with the colored image that was captured by the primary camera will produce a rich and detailed image.

In some phones, the secondary camera acts as the zoom lens. Huawei uses their cameras on the P30 Pro a bit differently but going into the entire details might end up making this post a bit lengthy and a bit boring for people who aren’t hardcore techies so I’d try to keep this balanced. However, if you’d like to see that in another post do let me know in the comments.

So that’s basically how multiple cameras work on smartphones
