iPhone 4S common faults and solutions

In this article, we will introduce you to some common problems in iPhone 4s, such as solutions to crashes when entering certain text, solutions to sudden screen expansion, etc.

Common faults and troubleshooting methods of iPhone 4S

1. The phone shuts down inexplicably, but the phone did not turn off when the other party called us.

Solution: Press and hold the power button and home button until the Apple logo appears on the screen. (Usually about 10 seconds)

2. In some programs, after entering certain text, the program will exit immediately.

Solution: Open Settings, General, and restore the keyboard dictionary.

3. The call cannot be broadcast or hung up. When called, the other party’s normal phone does not respond when the call is connected, and text messages cannot be sent.

Solution: This problem usually occurs when using a mobile card. After correctly setting the cellular data, turn on the cellular data and connect the phone to the Internet.

4. The screen interface suddenly expands.

Solution: Tap the screen three times with three fingers at the same time.

5. Click the screen to speak.

Solution: It means that the voiceover function is turned on on your mobile phone. Press the home button three times in quick succession. (You can also: Settings - General - Accessibility - Turn off voiceover. In this mode, the action of pulling down the screen is to pull to the right of the screen, which is the pull-down command).

6. There is no sound when making phone calls. The call needs to be hands-free to hear the sound.

Solution: This situation is usually caused by the phone getting wet and entering the headphone mode. Adjust the volume to see if there is prompt (headphone) mode. You can use an electric air blower with a hot setting to dry the earphone hole and tail charging hole for a period of time (you can control the time).

7. What should I do if I have installed 91 Assistant after jailbreaking and I don’t want to flash the phone but want to uninstall it?

Solution: Currently the safest, cheapest and most effective way is to install the pp assistant on your mobile phone (as for the adding method, check Baidu). Open app assistant - more - management - pxl management - uninstall.

8. After jailbreaking and installing 360, some calls cannot be made.

Solution: Open 360 - Interception Record - Interception Method - Only intercept blacklist.
