If your Lenovo smartphone is buggy and a simple reboot does not help, you can try resetting the settings to factory settings, in other words, doing a Hard Reset.
In this guide, we will tell you how to reset your Lenovo phone to factory settings in two ways that are suitable for all models, including a319, a320 and a536.
What can you do in Factory Mode?
Using Factory Mode is available to the user at any time. It is possible to test any component of the smartphone, up to rolling back the Android operating system. Factory settings mode is useful because it can bring the phone back to life if the OS update fails.
In addition, the user can conduct tests of gadget elements to check their performance, as well as measure the performance of the phone’s sensors.
Switching to factory mode allows you to change such technical characteristics of the device as:
- sound;
- sensitivity of touch elements and mechanical buttons;
- Android operating system;
- memory;
- backlight brightness.
In addition, clearing the cache and flash drive and calibrating the device will become available.
Menu items
Factory mode has two language packs: English and Chinese. The English interface is considered the most common. Depending on the phone brand, the factory mode has a different menu.
Below are the main points that the user will encounter on every smartphone:
| Item name | Meaning |
| Auto Test (Full Test) | Full check of the smartphone, where all components are tested |
| Item Test | Selective testing of one smartphone component |
| GPS | Checking modules responsible for location |
| Clear eMMC/wipe data/factory reset | Reset all settings to factory defaults |
| Debug Test | Checking for errors with further correction |
| Test Report | Check Reminder |
| Reboot | Rebooting the device |
At the end of the test, two message options may be displayed:
- test pass – successful;
- test fail - unsuccessful.
Hardware testing (module testing)
- Audio. Here you can set and change the volume level characteristics;
- Camera. Gives access to camera parameters that cannot be changed in normal telephone mode;
- Driving Current Camera. Provides the ability to read data on current strength from special sensors installed in the camera circuits. The average user will most likely not need this functionality;
- CPU Stress Test. Carrying out tests of mobile phone processors;
- Deep Idle Setting. Allows you to completely deactivate the ability to put the phone into sleep mode;
- Sleep Mode Setting. Changes sleep mode settings;
- ChargeBattery. Maximum detailed information about the battery and its charge level;
- Sensor. Makes changes to the smartphone sensor that cannot be made in the usual way;
- Multi-Touch. Changes the number of touch points on the phone screen;
- Location Engineer Mode. This section is intended for detailed testing of the GPS module.
How to turn it on?
Symptoms of turning on factory mode:
- the appearance of a translucent window with the message “Factory mode is on. ";
- turning off Wi-Fi;
- inability to use the services of a mobile operator;
- Pressing the power button turns off the gadget.
Enabling Factory mode is possible in two cases:
- when pressing a combination of buttons;
- the operating system refuses to boot.
Typically, the second option occurs unintentionally. For example, if the user wants to get Root rights or update the system.
Enabling Factory Mode varies depending on the brand of your phone.
Typically it goes like this:
- press the volume rocker button (up/down) together with the phone's power key;
- hold for 10-15 seconds.
In some devices, startup is done using three buttons. A combination of volume rockers, power and home buttons is used. After the completed operations, the user switches to factory mode. Moving through the list is done by pressing the volume buttons or touching your fingers. The “select” key is responsible for the on/off button.
Two-button mode control is relevant in phones:
Three buttons are used in devices such as:

The Lenovo K12 Pro has a 22.8 Wh (6000 mAh, 3.8 V) lithium-ion battery. We've already started to forget about it, but Lenovo K-series smartphones have always had excellent battery life, and the K12 continues the tradition. Even a huge diagonal does not leave its mark on this characteristic - it’s still worth remembering that we are dealing with an HD screen, and not a Full HD matrix. The K12 Pro battery will last for a day, in fact, in any case, and if you do not use the smartphone very actively, then you will have to charge it once every day and a half.
In our traditional test with Full HD video playback, with Wi-Fi turned on and updates active, the Lenovo K12 Pro showed a very good result of 15 hours. For a smartphone with a 6.8-inch LCD screen, it’s even, perhaps, more than good.
The kit includes a 20-watt adapter that allows you to fully charge your smartphone in about two hours. Quite a normal situation. If desired, Lenovo K12 Pro can also be used as a power bank - it supports reverse charging with a power of 2.5 W.
How to restore the system partition?
Recovering a system partition on Android is not easy. Before you begin resuscitation of the device, you need to make a backup copy in advance. This can be done by connecting the phone to the computer via a USB cable.
If you have a backup, do the following:
- In factory mode, select "Clear eMMC/wipe data/factory reset".
- A list of restore points will be presented. Specify the one you need. It is recommended to choose the penultimate or last one. Press the "Power" button to confirm.
- Wait a couple of seconds. The smartphone will restore the system and return you to normal mode.

Factory Mode on Android, what to do . In the Andro operating system >Recovery Mode? And this, by the way, is the recovery menu. There are other modes, for example, Factory Mode. What it is?
Content:
Factory Mode is translated from English as “ factory mode ”. Essentially, this is a utility built into the firmware for testing and configuring your smartphone. Factory Mode consists of several main points, there can be either 5 or 10 depending on the version of your device. Sometimes there is a menu with only 3 items. Here, for example, is Factory Mode, which consists of 9 menu items.
You may notice that the factory mode menu in this case is presented in English, which is good. On some smartphones, this menu may be in Chinese and it will be much more difficult to understand.
Some of the menu items:
- Full Test, Auto Test - a complete smartphone test, where all possible parameters are checked.
- Item Test - custom test. The user himself chooses what exactly he needs to check.
- GPS —checking the device’s positioning.
- Clear eMMC - reset the device to factory settings, delete all data (analogous to wipe data/factory reset in Recovery Mode).
- Debug Test - debugging mode.
- Test Report - notification about testing.
- Reboot —reboot the device.
In part, Factory Mode can replace Recovery Mode (for example, to reset settings), but these are completely different modes. In addition, on most devices, Factory Mode only allows you to test your smartphone, but will not allow you to perform other actions like the same reset (Hard Reset).
By the way, we draw your attention to the fact that moving around Factory Mode is done using mechanical keys (Power and sound control keys), although in some places touch control keys are also used, which are located under the screen.
How to enable Factory Mode?
Factory Mode can not be found in every smartphone. Some manufacturers have abandoned it for the simple reason that device testing is carried out using proprietary utilities or special key combinations.
If your device has Factory Mode, most often it starts:
By pressing the Power key and the volume up key of the switched off device:
When you press the Power key and the Volume Down key while the device is turned off:
When you press the Power key and the volume up and down keys while the device is turned off:
In this case, you can launch Recovery Mode or another menu, be careful.
How to exit Factory Mode?
It's very simple. In the Factory Mode menu you can see the Reboot - translated as “ Reboot ”.
This is what you need to select to reboot the device. In this case, the smartphone will boot in normal mode. You don't need to do anything else.
