The Xperia 1 II has the feeling that it has been waiting a long time for its release, probably due to the impact of the new coronavirus infection.

Normally, I'd be able to get one as soon as possible, but well, I had to wait almost four months since the announcement, but finally, finally.

Well, speaking of things to do with the Xperia 1 II that we got, we put a protective sheet on it.

I'll be very depressed if it gets scratched, so I'll put up the protective sheet made by Miyavix, which I've always been a part of.

Looking at the Miyabix lineup, we can see that there are 6 types of protective sheets: High hardness 9H type, High gloss type, Low reflection type, Scratch repair type, Blue light cut type, and Curved surface compatible TPU type.

There are so many different types to choose from for these selfish gadgeteers.

Up until now, the mainstream of protection sheets have been hard and easy to stick to, but more and more phones today have gently rounded edges, and while the Xperia 1 II looks flat at first glance, both the display surface and the back are curved towards the sides.

(The above image shows the Xperia 1 with a hard protective sheet)

In this case, the hard material will not be as aggressive as it should be, and the cover will be half-finished.

In this issue, I would like to challenge to attach a TPU material (OverLay FLEX) to a curved surface.

The reason why it is a challenge is because it uses TPU as a material to be able to stick to the curved surface of the display, and its flexibility makes it more difficult to stick.

The product notes also say "for advanced users".

There are a lot of protection films available on Amazon, not only from domestic manufacturers but also from Chinese manufacturers.

I've bought a few and tried them, but if they are not good enough, it's not only difficult to stick them on, but they can come off easily by a little thing, which is quite irritating.

There is also a glass type with a round rim. However, if the measurements are not good, it may not fit at all.

It's usually only for those types of products that you can get "a set of two or three for a great price! I think there are a lot of things like.

Now, let's get started.

This is my first time to use the curved surface protection sheet made by Miyavix.

I'm going to stick it on carefully with my experience of failures so far.

The first and most important thing to do is to make sure that you know ahead of time where the protective sheet will cover the phone and from where it's going to cover the phone, rather than just sticking it on out of the blue.

In the case of the back, the triple camera and flash portions are relatively easy to match because of the hollowed out guide, but if you stick it on with even the slightest deviation, the landing point where it ends up being attached may not be a good place to land.

It is important to know the top, bottom, left and right coverage area.

Another thing is that even if some dust gets mixed in with the usual protective sheet, you can remove it later by peeling off the sheet with tape, but you should not do that with this TPU material.

It's also important to remove the dust beforehand, and to do so in a dust-free environment when you attach it.

If you've just bought it, it's best to do this when you're ready to remove the protective film.

Proceed with the work without hurry.

Remove the white protective film, and you can feel the softness of the TPU material.

It's not easy to stick such a stubby protective sheet straight to the end.

The original white protective film is very flexible, so use this to your advantage.

Peel off just a little bit from the TPU film to firmly position the top portion of the Xperia 1 II for attachment.

This start is the most crucial.

Then, while peeling off the "Surface Protector Film", we attach it to the back of the Xperia 1 II.

At this point, while applying the film a little bit at a time, check from time to time to see if it is leaning to either side.

Even if you don't care at the beginning, the later we go, the bigger the gap becomes, so if you notice that this is not good, immediately go back to the original and start over from the beginning.

Once you get this start right, the rest will naturally stick to the whole thing.

Even if there are air bubbles in it, the softness and elasticity of the TPU material allows them to come out easily when pushed out.

Even if small bubbles remain, they'll disappear naturally in half a day.

Finally, peel off the "film for surface protection" and it is complete.

Don't be tempted to take it off and fix it when you get to this point.

The softness of the material means that there is a big chance that the material will stretch or be damaged and the protective sheet will become trash if you push it too hard.

To avoid reapplying it later, the first time is the most important.

The same goes for attaching to the surface.

It's a little more difficult because the notch on the surface is smaller than on the back side of the camera.

But the basics are the same: Use the notch on the camera and sensor as a reference point, and make sure you have a clear idea of the area to be covered on the top, bottom, left and right.

Align the parallel lines at the top of the display and check the balance on both sides.

If you proceed while removing the white adhesive film, you should be able to stick it straight on without any unexpected wrinkles.

When you finish attaching it to the Xperia 1 II safely, you can't even tell that it is attached to the whole thing, it's not an exaggeration to say that it is attached to the whole thing.

It sticks to the very edge of the corner, and there is no discomfort, because it is a thin material.

The hard type is easier to stick on, but it is thicker and only covers the flat areas, so it feels like you are sticking the protective film near the center.

Compared to that, there is something very pleasant about it.

Looking at the surface, the lines of the protective film don't overlap the display area, and the notches on the front camera and sensor are almost assimilated and the seams are not noticeable.

The transparency is good as well, with no color bleed when viewing text, photos, or videos, and it's easy to forget that the protective sheet is on.

I would venture to say that the glossy TPU material may leave some fingerprint marks as you touch it, but it's tolerable as it's easy to wipe off.

How strong is it, and what about the yellowing of the TPU material over time? But the protective sheet is a consumable product, so you can replace it if you're worried about it. .

I can't say I would recommend it to everyone, as it's undoubtedly difficult to do, but I can say that it sticks beautifully.

More importantly, you could protect the display surface and the back, but it's easy to accidentally slip your hand and drop it and scratch the side surface that doesn't have any protection, so you might want to consider putting it in a case.
