Remotely Clear Data from Your Android Apps using SureMDM

Applies to:
Product         SureMDM
Platform           Android


There are cases when the use of an Android device is not limited to just one user. Multiple visitors/users may use the device and it's applications and may end up inputting information. Before the device is used by a new visitor/user, it is needed that it is cleared of existing data. There has to be a way to clear user data after each visitor/user in the device in order to maintain user privacy and confidentiality. In fact, periodic cleaning of user data should be part of a good device management practice. Devices being used as kiosks in particular need the data clearing options.

Individually visiting these kiosks and manually clearing application and user data on the devices is time consuming and not the most efficient way of maintaining devices. Ability to remotely clear data on multiple devices would save precious time and effort.

With SureMDM, it is possible to clear user application data remotely. This option is available for all KNOX enabled or rooted devices. Devices that use signed Nix Agent for the platform can also use this feature.

To clear data of an application remotely using SureMDM, make sure that you have the latest SureMDM Nix Agent installed in the device and follow below mentioned :

1. Login to SureMDM Web Console


2. On SureMDM Home, select the device from the list of enrolled devices


3. Once device is selected, click on Apps from Quick Action Toolbar

select_apps button

4. On Application List prompt, identify and select the application


5. Click on Clear Data


6. Click OK on Cancel Confirmation prompt to continue


7.  Once successfully applied, you will get a prompt saying - Initiated Clear Data

Initiated Clear data

On successful completion of above steps, the application's user data including account settings will be cleared and the application will be reset to the state when it was freshly installed.

If you have multiple devices and want to clear data of a specific application installed in those devices, you don't have to individually visit every device from the list and perform the above mentioned steps. All you have to do is to create a job and apply it to multiple devices at one go. Follow below mentioned steps to create a job:

1. On SureMDM Home, click on Jobs


2. On Jobs screen, click on New Job


3. On Create Job prompt, select Android


4. On Create Job for Android prompt, select Application Settings - New


5. On Application Settings - New prompt, give a name to the job and select the application on which you want to perform Clear Data


6. Select Clear Data from Job Type dropdown menu


7. Click on OK to complete

8. Once back on SureMDM Home, select the devices and apply the job

Use Scenario: Hotels provide locked down Android devices to their guests when they check in . These devices are used by the guests to browse through food menu, available services, running offers, hotel policies etc. loaded on the device . Hotels even have feedback applications on the devices to get user ratings for their services. Guests use the devices for information and feedback during their stay. Post the guest check-out, the Android devices can be remotely cleared for user data using Clear Data feature and make them ready for the next set of guests in no time.

Taxi Services: Easy and Efficient with Smartphones and Tablets

With the advent of smart devices and their becoming powerful and affordable, businesses have found their uses in newer areas. These smart devices have revolutionized the way business is done today. Touch screen devices have become ubiquitous. The increase in the trend of using these devices have vastly improved the services offered, shortened the business response time, reduced the overall cost for business operations and especially proved very efficient for companies who have mobile workforce. 

Taxi service is one such industry that has benefited from the smart device revolution. Smartphones/tablets have replaced those expensive and bulky mobile data terminals.


These smart devices can now be terminals for the drivers where the jobs arrive. A driver can key in destination address on the device, pick up the passenger and find the most effective route using applications on the device.

Through integration with map software and effective touch screen, these devices have made driver’s job easy and efficient. Checking alternate routes, avoiding traffic, possible commute time and even fare payment has made not only the process streamlined but are also a step further for making passengers’ experience great.


Some taxi services have even started providing entertainment and information (infotainment) to the passengers. The driver's terminal or an additional tablet in the taxi provides a suitable platform to inform and advertise. Weather forecasts, concerts timings, upcoming conferences and tourist attractions can all be made available to the passenger using these devices. Kiosk software now also allows the tablet’s screen to be divided into sections/parts for more effective use of the screen space. This can be a source of additional revenue for the taxi company.

The whole setup can be further made effective using Mobile Device Management solutions like SureMDM. The MDM solutions lets you not only remotely push the jobs to deployed devices in taxis but it also gives you control over tracking, communicating, troubleshooting and much more.

Learn more about such innovative ways in which our customers in the Taxi Industry are using smartphones and tablets. Our range of products; SureLock, SureFox and SureVideo are currently being used by multiple Taxi Service companies across the world.

Applies to:
Product SureLock
Platform Android

The constant buzzing of your phone or tablet with every notification and alert seems maddening. And the consequent checking of the device can be a major source of distraction for anyone.  But, does that mean you should turn off notifications and alerts altogether?

Turning off notifications and alerts may not be a wise step and especially for Android device which only momentarily displays the notifications and gets collected in the notification panel which has to be swiped open from the top panel.

This is where Notifications Badges comes into the picture. The purpose of this feature is to let the user know how many unread alerts or notifications are there for each of the installed applications and notifies which applications need your immediate attention.

SureLock now has a new feature to show notification badge for all allowed applications which supports notifications.

Why some SureMDM features stopped working after I upgraded my Nix Agent?

Applies to:
Product All Andriod Products
Platform Android

42Gears's products have certain advanced features which require superuser privileges and work only on rooted devices. We recommend SuperSU, for superuser access management on android devices.

Unfortunately in latest release of SuperSU app, it revokes superuser permission for an application if an update to that application is installed. Once this happens, the application no longer has superuser privileges and few of its features might stop working. To overcome this user has to manually launch SuperSU and grant superuser access to that application again.

If you don't want to manually grant access every time you install an application update, there is an option in SuperSU to specify to remember permissions even after an update.

Follow below mentioned process to enable this option:

1. Launch SuperSU















2. Tap on Settings tab















3. Under Settings tab, check the Re-authentication option















Once this option is enabled, you don't have to manually access SuperSU and grant permission every time an update for the application is installed.
