Hi Everyone, This is my first tech blog and you know, I'm gonna tell you something interesting about the <b>Front Camera</b> of a mobile phone. You know, it's so hard to find a man who haven't faced for a selfie, I mean even a pet 😂.

So,  where did this all started??  Don't worry. I'm not gonna tell the revolution of the mobile phone 😅. 

Ok. do you remember, until like 2018, almost all mobile phones had <b>big bezels</b> on the top and the bottom. And normally, front camera was on the top bezel. And manufacturers kept narrowing and narrowing bezels because there was a game in <b>Screen To Body Ratio</b>. 

![PicsArt_11-20-08.39.44.jpg](https://cdn.steemitimages.com/DQmXes5D8FRF7c9npRyoNqqwVNEQo2yTG6M7YPnTM5USaQX/PicsArt_11-20-08.39.44.jpg)

Then some manufactures completely removed the top bezel and placed the front camera on the bottom bezel 😅. Actually it was innovative but not practical enough. 

Then came the most practical structure, <b>the notch</b>. It means now, there is no full top bezel but only the middle part and it's ok. You know, <b>even now iPhone 12 series also has a biiig notches</b>.

Then it became smaller and smaller until it appears like a water drop or a dew drop. So it was named as <b>waterdrop notch</b>.

Then smartphone manufacturers thought this notch is interrupting the viewing experience of the user. Then they removed the notch and brought <b>mechanism</b> to front camera such as, 

<b><li>POP-UP Camera </li>

You know, mechanisms are mechanisms. They add extra weight too. They are not as reliable as static camera. But this kind of cameras has many security features to keep moving parts safe and that cost money and that burden pass on to the buyer. But still smartphone manufacturers use this techniques. 

Then came the <b>sweet spot</b> of the front camera. It is in-display camera. It means there is a small cutout on the display to place the camera. If the front camera module has more than one camera, the cutout gets a pill shape.

You know, revolution stops at nothing 😅. Then what's next?. It is <b>Hide-in Display</b> Camera. It means the front camera is under the display. Then how the sensor capture light 😮? In this case, front camera is placed under the display and that area of the display has a special feature with dual layer pixel polarization. Then whenever you want to use front camera, that area of the display become transparent so the sensor can capture light. 

<b>ZTE</b> was the first manufacturer to make this official. You can see that under display camera by pointing a strong light to the area where the camera is. But you don't that kind of phone, right? 😅. So, don't try at home 🤭.

And there is another prototype by <b>VIVO</b>. In this, camera module is detachable. Whenever you want you can connect it to smartphone and use as the selfie camera or main camera.

And that's where this revolution leads us😅. An invisible front camera. Even now, despite of all this revolution, smartphone manufacturers still produce smartphones in basic phone factor because there is still demand for that factor. Some people like that <b>simplicity</b> rather than moving parts.

In my opinion in-display front camera is the sweet spot for front camera. It's elegant. Less distraction for viewing. So, what do you guys think? What is the best solution? Comment below what do you think.. 
Then, that's for now. Until next time, Peace ✌️.
