How to secure android phone?( android security checklist)

We give tips for more security for your Android smartphone.

Tip 1: Set up the screen lock

Without a lock, you open the door to all your data for attackers. By default, the SIM card is protected with a PIN. If not, activate it under Settings / Security and SIM lock . You should also set up a screen lock. Then only the cell phone can be accessed by anyone who knows the code, password or the appropriate pattern. Newer smartphones often have a fingerprint sensor on board, which you can also use for security. You set the lock in the settings under Security and Screen lock.

Tip 2: Install updates immediately 

Make sure that the operating system and all programs are always up to date and install updates immediately. The developers not only deliver new functions with updates, they also close security gaps. If there is a new version of Android, you will receive a notification. You should allow automatic updates for apps. To do this, go to the Play Store and tap on the three lines at the top left. Then select Settings and activate automatic updates – but ideally only via WLAN, otherwise you may have to pay for the data transfer.

Tip 3: Download from the Play Store only 

Download apps only from Google’s official Play Store, not from potentially dubious websites. Because there you are more likely to catch viruses and malware. To be on the safe side, you should prevent the installation of apps of unknown origin on your mobile phone. This is possible with older Android versions under Settings and Security . As of Android 8.0, you will find the menu item in the Settings under  Apps / Special Access . Install unknown apps at the bottom . Tap on it and you will see all apps already installed. Check that everyone says: Not allowed. Otherwise, tap on it and move the slider.

Tip 4: Pay attention to permissions 

Check the permissions it wants to grant for each app you install. This is on the app page in the Play Store under authorization details. A flashlight function, for example, does not require Internet access. If apps are already installed, remove individual authorizations under Settings / Apps / App authorizations .

Tip 5: encrypt the smartphone

If, despite all security measures, a stranger gets hold of your cell phone, they should not be able to read sensitive data – such as emails, contacts or access data. The encryption of the device protects against this. With most mobile phones, you have to trigger it yourself once. To do this, tap on Security / Encryption and select the Encrypt smartphone option  . 

Tip 6: Take care in the open WiFi 

You can surf for free in the open WiFi in the café or at the airport. But be careful: with relatively simple means, others can spy on you and read along. You should therefore never do home banking there. In addition, be cautious about all sites that you need to log in to, such as email or Amazon. At least the pages should provide SSL encryption when logging in, recognizable by https: //. Even better: surf over a secure VPN connection.

Tip 7: Deactivate connections 

Apps can determine your location via GPS and WiFi networks and create motion profiles. You should therefore deactivate all network functions if you do not use them all the time. This also includes Bluetooth and NFC, because the interfaces can offer attackers potential gateways. You switch off all these functions in the settings – under  Wireless and Networks and under Location . Slide the virtual controller to the off position.

Tip 8: activate theft protection 

There are advantages to turning on location detection: you can then locate your cell phone if it is lost. In addition, all data can then be deleted remotely. Of course, you must have activated the function before the device is lost. Allow location determination under Settings / User and Location . Then activate Security and Find my device . In an emergency, go to https://accounts.google.com in the browser and log in with your Google account.

Tip 9: Regular backups 

When the smartphone gives up, all data is gone – unless you back it up regularly. A backup of the photos is easiest with cloud services like Google Drive or OneDrive, which save them automatically. Google saves the settings and data of apps, WiFi passwords or the call history. Activate this via Settings / Save & reset and Back up my data .

Tip 10: Use the security app

The free security apps from Kaspersky, Avira or Bitdefender already protect against malware and scan new programs for threats. Some even have anti-theft functions. As of Android 8.0, you also activate the Play Protect function in the settings as additional protection , which checks installed apps for security gaps.
