How to Keep Your Android Device Secure Without Succumbing to Paranoia



In this age of cyber breaches and sensitive data leaks , keeping your personal and commercial information safe has never been more important. What’s more, the security of our data is perhaps more vulnerable than ever as most of it is now stored on our mobile devices.
With that in mind, it’s easy to see the absolute necessity of keeping them as secure as possible. However, the ultimate security would require you to disable all the wireless modules of your device. Additionally, you’d have to set up a 20-character password with letters, numbers, and special characters.
There’s a reasonable balance between data security and convenience on your Android devices.
How to Keep Your Android Device Secure The goal of this overview is to find a reasonable balance between data security on an Android device and the convenience of everyday use. If you think that you’re a target for a spearfishing cyberattack, you’d probably be better off following the advice from the paragraph above; for the rest of us, the 10 suggestions below should be plenty to allow us to stay safe.
#1. Look at the brand and hardware
Several things we’re going to talk about below, including firmware issues and authentication methods, depend heavily on the implementation in a particular smartphone. For example, cheaper devices may not have special additional cameras and depth sensors for FaceID , which could make it possible to fool them by a photo or simple mask.
If device security is important to you, make sure that you understand the relevant specifications before purchasing. Another obvious recommendation is, of course, to avoid buying from lesser-known brands (think Leagoo, Doogee, or Homtom) or shady sellers — saving a couple of hundred dollars isn’t usually worth the risk.
#2. Check the firmware
Although normally you’d expect to receive proper original firmware when buying a new device, it’s not unheard of for the store to install software of its own on a smartphone before selling it. The store rarely does it with purely malicious intent. Sometimes it could be localized firmware for the target market, sometimes the seller wants to earn extra money with bloatware, and so on.
Anyway, having non-original firmware is a security threat. Not only do you not know what’s hidden there, but you also usually miss important security updates for your device. Therefore, it’s always a good idea to download original firmware from the manufacturer’s website and install it after obtaining a new device. It’s a sensible thing to do with a new smartphone and a must if you buy a used item.
#3. Choose your authentication methods
Any decent Android smartphone these days comes with a range of authentication methods built-in. In most cases, you’d be offered to choose from a password, PIN code, screen pattern, fingerprint, and FaceID.
Let’s assume you’ve read the first section of...
