First Impression

Phone is bigger and the display color is a little yellowish/bluish as compared to my previous Iphone. But after a while I got used to it.
I also offed the true tone display cause I can't get used to it. But the brightness of the Iphone X changes accordingly to the light exposure.

Non Iphone X Layout and Iphone X Layout

Major apps have updated their apps to be Iphone X compatible but for Instagram, only the stories is not compatible.
As for youtube, you can zoom in for videos but it will be too zoomed for full video screen.

Camera

For me i think that the front camera is too overexposed. And the quality I feel for my front camera is the same as my previous phone or like it's actually worse? Well I can't say for much because haven/t been taking much photos so KIV. And the difference between Iphone X and an Iphone 8 is that X has a portrait effect even for front camera. But honestly, it sucks. Just use the back camera for the portrait effect.
Back camera I feel its better but then again, haven't been using much of the camera.

Additional 

Apps such as IMovie (YAY), Clips, Garage Band, etc has been added into the Iphone X without the need to pay for them.

Face ID

The phone is super sensitive with Face ID, like if you just tap the phone, it will automatically light up. Sometimes I will just wanna take a look at myself through the reflection but it will automatically light up and unlock. Or like when I wanna take a look at the time. It is so annoying.
And it only registers one face, so sometimes my phone doesn't unlock if I have my specs on.

Notifcations

When you scroll down/pull down the right side of the phone, it is the control centre. On the left side is your notifications. When it is locked, it will only for Notifications under the App like Whatsapp/Instagram/Telegram. Only when you unlock it with your face, it will then show Message from ____, ____ liked your photo, etc.  Then you will still have to slide up to head to home.

Speaker

Better quality speakers, louder than the previous iphones.

Verdict

Honestly, I don't think Iphone X is worth the money that you're paying for it. It's laggy and sensitive. And sometimes my assist touch will hang and I can't even use it as well. So, don't buy it, buy an iphone 8 instead.
