Do you think it is necessary for mobile phones to use a phone case tempered film?

I don't think it's necessary to wear a case and a film for the sake of protecting the phone.

First of all, the film will affect people's eyesight to a certain extent, reduce the light transmittance of the mobile phone screen, and the current mobile phone screen glass is hard enough, even if there are small scratches on the glass, it is difficult to see with the naked eye.

About the protective case: I actually won't sell the mobile phone I bought before, in the final analysis, I am reluctant, because every mobile phone has more or less accompanied me through ups and downs, and it is the scratches on the body that have witnessed these years. <>

I think it's very necessary, the phone just bought no shell, when I got on the card, my hand slipped and almost fell into the toilet ......Then I immediately put on the film and bought a phone case, and it turned out that I was right. Later, a few months later, while taking a shower in the dormitory, I put my phone on something on the windowsill, and it fell through the cracks of the blinds (the kind of hard ones in the school that can't be switched on and off, and that's the kind when installed!! Our dormitory was on the fourth floor, and I was stupid at the time, and I reacted when I heard someone downstairs say ......Then I asked my classmates downstairs to help me get it, the phone case was broken, the phone didn't do anything at all, and I still use this phone.

No, it does. Affects clarity.

The film can effectively protect the mobile phone screen from being scratched. Mobile phones are a device that we use a lot in our daily life, and it will cause slight friction when carried on the body and placed in a pocket or on the desktop, and the screen will be scratched over time, which will look very ugly.

The film can prevent dirt, most mobile phone screens are touch screen, the hand will be in direct contact when used, when the hand is sweaty or oily, it will be easy to absorb dust and produce dirt, and it will be difficult to clean over time.

Hello The newly bought mobile phone does not come with a tempered film, it is a thin layer of plastic film The new phone you buy will generally have a layer of disposable plastic film, which can be removed when you use it. When the mobile phone leaves the factory, the screen does not have a film, but please rest assured that the screen of the machine has been tested for scratch resistance before leaving the factory to prevent wear and tear within the normal operating range, and it will not affect the use without film. However, the film can effectively avoid some sharp objects from causing direct damage to the screen, and you can choose whether to apply the film according to your personal preference.

If you need a film, it is recommended that you contact your local service center or specialty store to inquire about purchasing and applying the film. You can check the service center information and dealer information through the official website.

The mobile phone tempered film can completely cover the original screen surface, prevent damage and scratches by external forces, and increase the impact absorption, which is 5 times higher than the standard of PET film, which can effectively protect the mobile phone screen, and has a greater effect on the mobile phone screen, but also has certain limitations.

The following is a brief introduction to the advantages of mobile phone tempered film:

Explosion-proof and scratch-proof: It can prevent the glass panel from being broken and scattered due to accidental impact of the mobile phone, reduce the hidden damage of the glass panel, ensure the safety of users, and prevent accidental scratches and affect the beauty of the mobile phone; It is easy to use, no bubbles, and the light transmittance of the picture is as high as 98%, which does not affect the use of mobile phone cases and other mobile phone accessories.

A brief introduction to the shortcomings of mobile phone tempered film:

Compared with other films, it is relatively thick, and it also affects the sensitivity of the touch screen, due to the characteristics of tempered glass is hard and brittle, the overall performance is fragile; Although the strength of tempered glass is stronger than that of ordinary glass, tempered glass has the possibility of self-explosion, while ordinary glass does not have the possibility of self-explosion.

Do you need a tempered film for your mobile phone? Is it protective? I see.

Can tempered film really shatter screen? The answer is yes!

Anyone who has a little common sense of physics knows the relationship between the unit force area and the pressure! The function of the tempered film is to disperse the force to the entire screen.

However, if it hits the side or a corner, the tempered film will not play its decisive role in riot protection! It also plays the same role as ordinary membranes:

The tempered film is glued together with the screen, which effectively reduces the damage of the screen!

I can tell you responsibly that mobile phones can be left without film!

In fact, for the vast majority of mobile phones, you can stick the film, or not, it is recommended to choose according to your own habits, paste or not, in fact, there are pros and cons.

Advantages of mobile phone film:

The first benefit of mobile phone film is that it can beKeep your phone screen brand new。If you don't use the mobile phone film, you will find that the mobile phone will have scratches and dust after a long time, and it will look old.

The second benefit of mobile phone film is to prevent falling injuries. Because mobile phones are now large-screen smartphones, if you are not careful, it is easy to fall to the ground, and if there is no mobile phone film as protection, it is easy to break the screen.

The third benefit of mobile phone film is that it is anti-scratch. Because touchscreen phones often use fingers to swipe around, if the nails are longer, the screen may be scratched if you are not careful. There is also the possibility of scratching the screen by putting the phone in the bag and coming into contact with some other sharp objects such as keys and cosmetics

My good friend is a professional seller of mobile phones, so she knows more about mobile phones (film and how to apply film, I won't repeat the method and process of filming, I can go to check the relevant teaching**), she told me when chatting, try not to film on mobile phones, because there are some drawbacks:

The first one is that it will affect the heat dissipation of the phone

If you play with your phone for a long time, your phone will generate a lot of heat. If there is a mobile phone film as an obstacle, then the heat cannot be discharged as soon as possible, and the continuous high temperature will damage the battery, which will eventually affect the service life of the mobile phone.

Another disadvantage is that it hurts the eyes

The mobile phone film will weaken the brightness of the mobile phone screen, and it is easy to cause eye fatigue after long-term use. Moreover, the film will make the screen blurry, and it will damage the vision after looking at it for a long time.

The most important point is that it is harmful to health

If you buy those inferior mobile phone films, although they are cheap and the bottom adhesive is sticky, they contain toxic benzene! Long-term use can affect physical health.

But what I want to say is that there is no need to worry too much about whether the mobile phone is attached to the film or not. If you want to stick it, if you don't stick it, you won't stick it, the initiative is in your own hands, but my advice is that when you start buying a mobile phone, you should try to stick the film. Because the mobile phone is very expensive, it costs a lot of money, if you get hurt and damaged, it is really distressing, when the mobile phone is used for two or three years, it doesn't feel very easy to use, or when you want to change to a new phone, then tear off the mobile phone film, so that you can use it as a new mobile phone (Do you think I'm witty?

Clever? Because that's what I did, give me a thumbs up!

The benefits and disadvantages of mobile phone films are detailed above, as well as related recommendationsI hope to be able to help friends in need, okay, let's talk about it today If you don't understand something, or have better opinions and suggestions, you can hit the comment area, and everyone will communicate together, make progress together, bye-bye

I have two mobile phones in my daily life, iphone13 film without case, iphone se3 without film without case.

I used to have two phones with cases and films, but recently I have figured it out - there is no need for that.

First, let's talk about mobile phone cases first.

The official weight of iPhone13 is 173G, the official weight of iPhone SE3 is 144G, and a protective and not too thin phone case is about 22G, which will make the two phones gain weight respectively, which is a big weight increase, and when you hold it, you can clearly feel that this 22G makes the phone thicker and heavier.

In addition, each generation of iPhone is upgrading the front and rear panel materials to achieve the purpose of being more resistant to falls, starting from iPhone12, the front and rear glass panels have been upgraded to super ceramic crystal glass, which is more resistant to falls than the previous tempered glass. Now even the cheap SE3 glass has been upgraded to super porcelain crystal.

Moreover, I have been running naked for a long time before the iphone11, and I have never broken it. So, I don't bring a phone case.

Second, let's talk about screen film.

In terms of weight, the weight of a glass mobile phone film is about 10g, and the weight increase brought to iPhone13 and SE3 is and. In fact, the hand-held feeling is not obvious, and the film will become heavier.

But the reason why I am willing to apply the film is not because it is "not heavy", but because the phone screen is the core part of my interaction with the phone, and the view information is transmitted to me through the screen, and once the screen has scratches that obviously affect the senses, it affects my core experience. It doesn't matter how serious the scratches on the bezels and backplate are, but the screen can't. So I put a film on the iphone13.

But why don't you give SE3 a film, because SE3 is my spare machine, and the quality of SE3's screen is so low that I am already very dissatisfied if he doesn't scratch it, and I don't care if I don't stick the film and have scratches. And SE3 is still curved, with a home button old-fashioned shape, the film will make the front of the machine feel particularly poor, so, still don't stick.

3. Summary. Various mobile phone manufacturers have invested huge manpower and financial resources to study how to make mobile phones lighter and thinner. And the biggest benefit of the film is that you can sell a few hundred more dollars when you sell second-hand, think about it, for a few hundred dollars, you have been holding a mobile phone as thick as a brick for many years, is it worth it?!
