I. The solution to the black screen of the smartphone
What to do when your smartphone has a black screen during use? The following editors start with the solutions for two different devices, Android phones and iPhone phones.
1. The solution to the black screen of Apple mobile phone
Solution 1: Force restart your device
Different models of devices have different restart methods. The specific steps are as follows:
· Force restart iPhone X and later models; iPhone 8 or iPhone 8 Plus:
Press and release the “Volume up“Button, press and release the “Volume down” Button, then press and hold the “Side Button” until the Apple logo appears and release the button to complete the restart.
· To force restart your iPhone 7 or iPhone 7 Plus:
Press and hold the “Volume Down button” and “Sleep/Wake button” at the same time, and release both buttons at the same time when the Apple logo appears.

Press and hold the Sleep/Wake button and the Home button at the same time, and release both buttons when the Apple logo appears.
Solution 2: Try connecting to a power source to charge the device

2. The solution to the black screen of Android phones
The black screen death of Android mobile phones is also relatively common, and generally speaking, there are two reasons: hardware and software problems.
If caused by external force like falling, pressure, water ingress, or overheating, it is mostly a hardware problem; if caused by downloading software, deleting system files, or failing to boot after flashing, it is mostly a software or system problem.
Solution 1: Check your phone battery
When an Android phonevibrates and sounds upon being turned on with a dark screen, the first step is to check the battery. If the phone responds, it indicates that the battery is still functional. Battery issues can be ruled out except for aging and water damage. In the case of aging, replace the battery with the same type. If the phone can be turned on normally, replace it with a new battery.
If the battery is dead or enters a deep sleep state (not used for a long time), try to turn it on after charging for half an hour, or press and hold the power button for more than 10 seconds and try again. If the battery can be removed, it can be charged with a universal charger (a strong current can activate the battery).
Solution 2: Check the phone screen.
The screen may fail under external force, like falling to the ground. To troubleshoot, try starting the device with the power button. If it starts up normally, the issue is resolved. If the screen remains unresponsive, it may be a hardware fault.
Solution 3: Check whether you can enter Recovery and reset the device.
Two cases of hardware problems can cause a black screen on a mobile phone. If the phone is stuck on the logo screen, try entering recovery mode by pressing and holding the power and volume down buttons. Reset the device from this interface.
II. The solution to the slow running of the smartphone
1. The solution to the slow running of Apple mobile phones
Solution 1: Uninstall unnecessary apps
The method is as follows: Find (Settings)-(General)-(iPhone storage). Then check which applications occupy a large storage space and clean them up.
Solution 2: Reduce the rendering of visual effects
To enhance the device’s interface and icons, Apple has included options to increase visual effects. However, this can lead to increased operating pressure and slow down the device. To alleviate this, consider turning off these options.
The steps are as follows:
Turn on the device, find “Settings” – “Accessibility“, and turn on “Reduce Motion“.
Solution 3: Clear Safari browser history data
To optimize Safari browser performance on Apple devices, users can clear history and website data by going to “Settings” – “Safari Browser” and selecting “Clear History and Website Data“.
Solution 4: Clean up the app cache in the device
Regularly clearing the cache data in iPhone applications can help alleviate slow device performance caused by accumulation of cache records.
Of course, in addition to the above methods, you can restart the device and use Renee iPassfix to repair the damaged iOS system.
2. The solution to the slow running of Android phones
Solution 1: Virus scan
To prevent virus attacks on Android phones due to the open operating system, utilize third-party security software for virus scanning and system purification.
Solution 2: Uninstall unused software
To optimize mobile phone performance, uninstall unnecessary applications and clear cache files to free up memory space. This will prevent the device from running slowly over time.
Solution 3: Do not use live wallpapers
Relatively speaking, static wallpapers take up much less memory space than live wallpapers, so switching to static wallpapers can prevent Android devices from running slowly.
Solution 4: Use less desktop gadgets
Gadgets such as weather, alarm clock, wallpaper, etc. will take up the memory of the phone and cause the phone to slow down. So try to use desktop gadgets as little as possible.
Solution 5: Turn off background running programs
When there are too many applications open at the same time, the memory space will be tight, which will make the phone run slowly. You can solve the problem by closing programs running in the background.
Solution 6: Factory reset
Restoring factory settings will clear all files, caches, and junk data, and restore the system to its original factory size.
Friendly reminder: Before restoring the factory settings, please make a backup in advance to avoid data loss.
