1、 Why is the screen of an iPhone malfunctioning and jumping

1) The touch screen is broken (such as encountering greasy or magnetic environments).
2) The motherboard is leaking electricity. 3、 The battery is aging and damaged.

Generally speaking, the third possibility is the highest, and choosing to replace the battery can solve the problem of iPhone jumping.

2、 How to solve the malfunction and jumping of the iPhone 5s touch screen:

1) When users encounter screen malfunction while using their mobile phones, they can long press the home button while the screen is locked to enable voice control function. Then at this point, it is said that players can choose to play a song and then select the touch function to restore it. We can wait for a while and then we will find that the touchscreen issue has been fixed.


2) Users can also wait until their phone runs out of battery, and the phone will enter an automatic shutdown state. At this time, users can charge the phone and then restore touch screen operation after turning it on.

3) Users can connect their iPhone 5s to iTunes and upgrade their iPhone 5s to the latest version of the iOS system. (jailbroken users need to be aware that they cannot directly upgrade their iOS version on iTunes)

4) Users can also choose to double-click the home button, and then we will exit all programs running in the background, which is also a solution to screen failure.

5) Users can long press the power button on their phone and then hold down the home button to return to the home screen. This is also a solution to screen malfunction.




3、 IPhone 6/6 Plus touch screen malfunction? Solution to screen malfunction

1）. The first thing to do is to restart the iPhone and simultaneously press the "sleep/wake" button (also known as the power button) and the Home button until you see the Apple logo displayed on the screen.
2）. Some users solve this problem by selecting "Settings" - "General" - "Reset" - "Reset All Settings" in sequence. Users need to re-enter their password, change their wallpaper, and reset their Touch ID, but their data will not be deleted.


3）. Users who encountered iPhone 6/6 Plus touchscreen malfunction were able to solve the problem by restoring factory settings, but all information on the phone will be lost, so users need to back up important data in advance.

There are also some available methods that everyone can try:

——You can clean the screen with a slightly damp, lint free soft cloth.

——Do not use the device immediately while wearing gloves, when your hands are wet, or after applying hand cream.

——If you are using a phone case or plastic protective film or film on the display screen, try removing the screen protector and testing the device without them.


Open the "Map" application and double-click on each corner, then press the middle button to verify if it has zoomed in to each section.
If a certain area in other application software is affected, please note this location and try to verify the touch function of this location in the "Map" application software.


The main reason for Apple phones experiencing a situation similar to "touchscreen malfunction and jumping" is due to touchscreen malfunctions or low battery power, etc. Therefore, when we encounter this situation, the first thing we need to do is to determine the specific part of the problem based on our own judgment measures. Then, we can solve it by long pressing the power button or restarting the phone, and other basic steps. If we still cannot achieve normal use after trying this method, we can also seek help from professional maintenance personnel.

1. Methods to Repair a Phone Screen

1. Replace the outer screen (pressure screen) using equipment

Screen pressing is a common method for repairing cracked phone screens, primarily used when the outer layer of the screen's glass is damaged. Since it involves repairing the outer screen, the inner screen of your phone must remain intact to proceed with this method. The process involves reattaching the new outer glass layer with the display layer and then using specialized equipment to press them together, ensuring a secure bond. The advantage of this method is its relatively low repair cost, and it does not affect other functions of the phone after the repair.





However, it should be noted that screen pressing requires professional equipment and technology, which cannot be operated by ordinary repair shops, and it is also impossible to press the screen by oneself.



2. Replace the entire screen

If our phone screen is severely damaged and the internal screen is already damaged (screen display is abnormal, screen leakage, lines, black screen), then we need to consider replacing the screen.



Screen replacement is the process of removing the entire screen and replacing it with a new one. The advantage of this method is that it can completely solve the problem, but the price of the original screen is relatively high, and reliable repairers need to be found to ensure the quality of the screen.

2、 The price for changing the screen

The price of screen replacement varies depending on the brand, model, and repair method. Generally speaking, if only the external screen is broken, we only need to find a professional repair shop to replace the external screen, which may cost around 120-350 yuan. It should be noted that replacing the external screen can only be done at the store, and those who can come to replace it are scammers.







If the internal screen is damaged, replacing the original screen may be more expensive. If you have high requirements, you can directly replace it with an original screen assembly. If the requirements are not very high, you can replace it with a brand screen assembly. If it is only a spare machine or just wants to export data, you can directly replace it with an assembled screen.



In addition, it is recommended to choose to have your phone screen repaired in store or by mail. Some home repair and screen replacement services often use an assembled screen to replace your original screen, especially if your phone only has a broken external screen. When replacing a phone screen, don't just look at the price. The price of replacing the external screen is closely related to the repair techniques of the technician. Some cheap repair shops have many tricks for replacing the external screen, such as not bearing the risk of the internal screen, which will ultimately lead to the price of repairing the screen increasing several times. The same goes for replacing the screen assembly. There are assembled screens, branded screens, press fit screens, face change screens, original disassembled screens, original touch screen replacement, screen replacement, and so on in the market. Anyway, remember that you get what you pay for. Try to repair the screen in a store that only does repairs.





In summary, if your phone screen is damaged and only the external screen is broken, we only need to replace the external screen. If the internal screen is damaged, we need to replace the entire screen assembly. We can choose the appropriate repair method according to our own situation. At the same time, when choosing a repair shop, it is necessary to choose a reliable merchant to ensure the quality and effectiveness of the repair.

1、 The main types of mobile phone screens

At present, the mainstream mobile phone screens are mainly divided into two categories: LCD (liquid crystal screen) and OLED (organic light-emitting diode screen), and OLED screens have derived various technical solutions such as AMOLED, LTPO, Micro LED, etc.

1. LCD screen: classic and durable, with realistic colors

LCD (Liquid Crystal Display), also known as liquid crystal display screen, works by providing light source through the backlight layer, and then controlling the degree of light passing through through the rotation of liquid crystal molecules to display different colors.

Features:

✅ Natural color: Due to the native color of LCD screens, it is suitable for users who like realistic display effects.

✅ Good eye protection effect: LCD screens do not experience the common "flicker" problem of OLED screens, making them more eye friendly.

✅ Long lifespan: LCD screens are not prone to burn-in (there will be no residual images after long-term use).

❌ Low contrast: Due to the dependence of LCD on backlight, it cannot display pure black, and black often appears grayish.

❌ High power consumption: The backlight layer is always on, even if the black part is displayed, it is still consuming power.

❌ Difficult to make very thin: LCD screens have a large thickness, which is not conducive to ultra-thin phone design.

Common LCD screen types:

IPS LCD: With a large viewing angle and excellent color performance, it is commonly used in mid-range models.

TFT LCD: outdated technology with light colors and high energy consumption, has gradually been phased out.

Suitable for:

✅ People who use mobile phones for a long time (less flicker, better eye protection)

✅ Users who prefer natural colors (avoid oversaturated colors)

✅ Users with limited budget (LCD screen costs are relatively low)

Representative models: iPhone 11, iPhone SE 3, Redmi Note 12



2. OLED screen: vibrant colors, high contrast

OLED (Organic Light Emitting Diode) screens are composed of self luminous pixels, each of which can emit light independently without the need for a backlight layer, thus achieving pure black display and high contrast.

Features:

✅ Colorful: OLED screens have a wider color gamut and more vibrant display effects.

✅ High contrast: It can present true black and display more vividly.

✅ Lower energy consumption: OLED screens can turn off pixels when displaying black areas, reducing power consumption (but higher power consumption when displaying white).

✅ The screen can be made thinner and more flexible, which is beneficial for foldable and curved screen designs.

❌ Easy screen burn-in: Long term fixed display of a certain screen may cause ghosting (such as navigation bar, status bar).

❌ Strobe issue: OLED screens typically use PWM dimming, which may cause eye fatigue at low brightness.

❌ High cost: High quality OLED screens are expensive and are usually used for mid to high end models.

Common OLED screen technologies:

AMOLED (Active Matrix OLED): commonly found in brands such as Samsung and Apple, with more vibrant colors.

LTPO AMOLED: Supports variable refresh rates (such as 1Hz-120Hz) to improve smoothness while reducing power consumption, commonly seen in flagship models.

Micro LED: At the forefront of technology, it has the advantages of OLED and solves the problem of screen burn-in, but currently it is expensive and has not been widely commercialized.

Suitable for:

✅ Users who pursue high contrast and bright colors (like the "transparency" of the screen)

✅ Users who enjoy gaming and high refresh rate experience (OLED screen response speed is fast)

✅ Users who hope their phones are thinner and lighter (with a more streamlined OLED structure)

Representative models: iPhone 15 Pro, Samsung Galaxy S23 Ultra, Xiaomi 14 Pro



3、 Refresh rate: an important factor affecting smoothness

In addition to screen type, refresh rate is also a key indicator that affects the screen experience of mobile phones.

60Hz (standard refresh rate): The most basic refresh rate, with stable but not smooth images.

90Hz/120Hz (high refresh rate): smoother operation, suitable for sliding social media, playing games and other scenarios.

144Hz and above: commonly found in gaming phones, the ultra-high refresh rate brings a more ultimate smooth experience.

LTPO variable refresh rate (1Hz-120Hz): The refresh rate can be dynamically adjusted according to the usage scenario, which is energy-saving and smooth. It is standard on flagship models.

Suitable for people with high screen refresh rate:

✅ I enjoy playing games (faster response time, reduced ghosting)

✅ Regularly browse social media (smoother scrolling, better visual experience)

✅ Pursuing power saving and smoothness (LTPO technology is the best choice)

4、 Eye protection mode: reduces screen damage to the eyes

Staring at the screen for a long time can easily cause eye fatigue, blue light damage, and other problems. The following techniques can alleviate them to a certain extent:

DC dimming (reducing low-frequency flicker): More eye friendly than PWM dimming, but may affect color accuracy.

Low blue light mode: reduces high-energy blue light radiation and lowers the risk of eye damage.

• Paper like eye protection mode (such as Honor like natural light screen): simulates the reading effect of paper and is suitable for long-term reading.

If your eyes are sensitive, it is recommended to choose a phone that supports DC dimming or eye protection mode.

Comparison of LCD screen and OLED screen principles

Price reference for mobile phone screensUpon entering a mobile phone repair shop, you will discover that the prices for screen replacements vary widely across different brands and models. Taking Apple phones as an example, here is a simple price reference for you:iPhone 13 seriesPrice of the outer screen: approximately 500~700 yuanPrice of the inner screen: approximately between 600 and 1300 yuanScreen assembly price: approximately around 1600~1900 yuaniPhone 14 seriesPrice of outer screen: approximately 700~900 yuanPrice of the inner screen: approximately 900~1700 yuanScreen assembly price: approximately around 1700~2300 yuaniPhone 15 seriesPrice of the outer screen: approximately around 1100 yuanPrice of the inner screen: approximately between 1200 and 2200 yuanScreen assembly price: approximately around 1700~2400 yuaniPhone 16 seriesScreen assembly price: approximately around 1700~2400 yuan
Why is it so expensive to replace a phone screen?The reason why mobile phone screens are expensive lies primarily in their complex composition. A complete mobile phone screen typically consists of an outer screen (touch screen), an inner screen (display screen), and an adhesive layer in between.When a mobile phone screen is shattered, it could be due to a cracked outer screen or simultaneous damage to both the outer and inner screens. Therefore, during the repair process, it is often necessary to replace both parts simultaneously. This not only increases the complexity of the repair but also raises the repair cost.Moreover, with the continuous development of mobile phone technology, the composition and structure of mobile phone screens are also constantly being updated and upgraded. The emergence of these new technologies may also lead to an increase in the cost of repairing mobile phone screens.In addition, apart from the cost of the phone screen itself, the technical cost of replacing a phone screen is also significant. This is because the connection between the screen and the motherboard has become increasingly precise, and even the slightest mistake can damage other components.Therefore, the cost of repairing a screen is high due to the nature of the phone screen itself and the technical difficulty of the repair process.
How to find a repair service for screen replacement of a mobile phone?There are generally three ways to repair or replace a broken mobile phone screen:Firstly, one may choose official maintenance, which is transparent in price and guaranteed in quality, but often comes at a high cost;Secondly, through third-party repair platforms, the prices are relatively cheaper.Lastly, if you have all the necessary tools, you can also try purchasing a screen and replacing it yourself.It is important to note that one must possess relevant replacement experience and knowledge reserves, otherwise it is easy to end up making a mess of the replacement process.Of course, if you want an experienced technician to replace the screen of your phone, you can always turn to Geek Repair.Whether it's a broken outer screen, damaged inner screen, or a need to replace the entire screen assembly, we offer on-site repair services. You can easily solve your phone screen issues without leaving your home.

Don't panic, the first step in self-study is to "line out" the screen

'Screen out' often means that the internal screen is damaged, so it's better to do it yourself instead of wasting money. Taking S15Pro as an example, the entire screen replacement process is broken down into 7 key nodes, each step accompanied by real-life photos, and following along can save a lot of maintenance costs.

02
Removing the back cover: The glass material needs to be 'translated'

2.1 ◇ First, cut open the double-sided tape, and then lift the cover in parallel
Lightly scratch along the border with a thin card, loosen the double-sided tape completely, and then move it as a whole. Avoid breaking it hard at 90 °, otherwise the back cover will instantly break into a "puzzle".



2.2 ◇ Remove the protective cover and battery
After removing the back cover, unscrew all the fixing screws around the body without missing a single screw; After removing the protective cover, disconnect the battery and power off the motherboard to avoid short circuits during installation.

03
Take the small board: first disconnect the cable and then take the screw

3.1 ◇ Loosen the display cable and charging port
Gently loosen the speaker and display cable interface, and there is also a straight screw on the top of the small board. After removing it, all cables can be pulled out.

3.2 ◇ Remove the card tray and protect the red dust-proof adhesive
Use tweezers to grip the card holder and gently shake it out; Use a leaf shaped pick to lift the small red leather circle next to it to prevent it from hooking onto the wiring when disassembling the screen.

04
Dismantling old screen: Blade+8+1 combination method

4.1 ◇ Cut open the sealant and apply 8+1 drops of solubilizing aid
Stick the blade tightly around the screen, cut off the sealant first, and then drip a small amount of 8+1 solvent to soften the glue for easy separation.

4.2 ◇ Card stitching, slow work produces fine work
The nail is stuck in the gap, and the card is slowly pushed along the edge. After all the double-sided tape is scraped loose, the entire screen can be removed.

05
Clean up residual adhesive and apply UV glue, and apply sealant to the middle frame

5.1 ◇ Special UV double-sided adhesive for cranks is put into use
Clean up all the old adhesive on the middle frame, apply UV double-sided adhesive specifically for the crankshaft, and apply a circle of sealant around the edges. The amount should be small rather than large - if the adhesive seeps out, it will create bubbles on the new screen.

5.2 ◇ Installing a new screen: align first and then press down
After inserting the cable and aligning the top, gently press down to ensure that the double-sided tape is fully adhered to the middle frame; Push on the battery and perform a power on self-test. If the touch and display are normal, proceed to the next step.

06
Reinstall the small board: plug the charging port first

Before putting the small board back in, first insert the charging port into the hole and fix it, then fasten all the cables in sequence, and finally reinstall the battery - the appearance of the startup logo indicates that the hardware is ready.



07
Upper protective cover, rear cover, and sealant

7.1 ◇ Tighten all screws in place
The speaker, charging port, and small board screws have all been reset; Clean up the residual adhesive on the protective cover and back cover, and then apply special sealant.

7.2 ◇ Cover and flatten, installation completed
Align the back cover with the buckle and lightly press it to fit. If the fingerprint and power button rebound normally, it means the whole machine has been restored. Power on test of various functions, no "wires" on the screen, sensitive touch, normal sound - great success!
