How to enter engineering mode on mobile phone
In recent years, mobile phone engineering mode has become the focus of many users. Engineering Mode is an advanced functional interface hidden by mobile phone manufacturers for testing and debugging equipment, and is usually not directly accessible to ordinary users. Through the engineering mode, users can view hardware information, calibrate sensors, test network signals, etc., but improper operation may cause equipment failure. This article will introduce in detail how to enter the engineering mode of different brands of mobile phones, and attach an analysis of hot topics and hot content in the past 10 days.

2. How to enter engineering mode on your mobile phone
The following are the detailed steps for mainstream brand mobile phones to enter engineering mode:
| brand | Entry method | Things to note |
|---|---|---|
| Huawei/Honor | Enter *#*#2846579#*#* on the dialing interface | Some models need to turn on "Developer Options" in settings |
| Xiaomi/Redmi | Enter *#*#6484#*#* on the dialing interface | MIUI 12 and above may restrict access |
| OPPO | Enter *#899# on the dialing interface | You need to click the version number multiple times in "About Phone" |

| Samsung | Enter *#0*# on the dialing interface | The international version is universal, but may be restricted by national banks. |
| iPhone | Need to connect to computer to use iTunes or third-party tools | Unofficial channels are risky |
3. Functions and risk warnings of engineering mode
Engineering mode usually includes the following functional modules:
1.Hardware testing: Detection of screen touch, speakers, cameras and other components.
2.Network information: Check signal strength, base station connection status, etc.
3.battery calibration:Reset battery statistics (please operate with caution).
4.Sensor debugging: Data monitoring of sensors such as gravity sensors and gyroscopes.
Risk warning:
• Misoperation may result in system instability or data loss
• Some options will trigger hardware reset (such as baseband parameters)
• Non-professionals are advised to only view the information and avoid modifying parameters.
4. User FAQs
Q: What is the difference between engineering mode and developer options?
A: The developer options are mainly for APP debugging, while the engineering mode involves the underlying parameters of the hardware.
Q: Will the warranty be lost if I enter engineering mode?
A: Merely viewing the information does not affect the warranty, but modifying key parameters may invalidate the warranty.
Q: What should I do if there is no response after entering the code?
A: It may be that the model is not supported or the system version is restricted. You can try to enter through the ADB command.
As mobile phone functions become increasingly complex, the threshold for engineering models is also increasing. It is recommended that users back up important data before operation and give priority to obtaining technical support through official channels. If you need to deeply detect mobile phone hardware problems, it is still recommended to go to a brand authorized service outlet.
