Android has had its fair share of security flaws over the course of its many years of existence. According to Check Point, 400 security flaws have been discovered in over a billion cell phones, transforming them into excellent espionage tools. The recently discovered flaw affects roughly 40% of Android phones worldwide, with 90% of them now on the market in the United States.
Google, Samsung, LG, Xiaomi, and OnePlus are among the companies affected by the flaws. Qualcomm’s Snapdragon digital signal processors (DSPs), which are used to manage Android’s day-to-day tasks, have “Achilles” security flaws.
This security flaw allows hackers to gain the advantage of the hardware features of each device. These included fast charging and augmented reality. These technologies added convenience to many users but also resulted in a major lapse in security.
Despite publishing security updates, the Android operating system and device manufacturers have failed to implement them. It’s not good for Android’s popularity among tech nerds, especially when competing with Apple. modern business cyber sccurity tools available here primasecure.com

Android Introduced New Security Options
Over the years, Android updates increased the uniformity of the user interface while also providing better security options to its users than its predecessor. One of the changes included the operating system introducing a Privacy Dashboard that allows users to see what data the apps are accessing.
The Privacy Dashboard provided users with a consolidated view of their permissions settings. It also provided information on what data is accessed, how frequently it is accessed, and which apps access it. Furthermore, users were able to inquire as to why an app accessed sensitive data.
On compatible devices, Google had also added Quick Settings toggles that quickly limit app access to the microphone and camera. When the toggles are turned off, the camera and audio streams will be received by an app that accesses these sensors.
Several previous attacks allowed hackers to remotely access the hardware of a smartphone. Without the smartphone user’s knowledge, hackers could remotely control the device and access its hardware.
The operating system also introduced approximate geolocation instead of the exact location to mitigate security risks. This new security policy that Android launched has an impact on some of the popular must-have apps. Because of new approximate location permissions, apps can now only view users’ estimated positions rather than their exact ones.
For example, weather applications do not require an actual location to provide an accurate prediction. It will increase protection against location-based trackers and advertisers. But these options still do not guarantee that Android is immune to cyberattacks. Plus, the collaborative, open, and distributive nature of the operating system doesn’t help its cause.
Even iOS isn’t More Secure Than Android
Researchers recently discovered high-risk vulnerabilities in 38% of iOS apps and 43% of Android apps. They discovered that the majority of security flaws were shared by both systems. The most common issue is insecure data storage, which is present in 76% of mobile apps. Passwords, bank information, personal information, and correspondence are all at risk.
iOS devices can even be remotely hacked without the owner’s interaction. Between June 2020 and February 2021, hackers used Pegasus to gain access to the iPhones of nine Bahraini activists and political protestors. Similar hacks were discovered by the governments of Qatar and Bahrain, according to the researchers.
Hackers used zero-click attacks on infected iPhones. Because they do not require user interaction, zero-click attacks are more sophisticated than traditional malware attacks. It shows that most of the problems are common to smartphones regardless of the operating system.
It is why a closer inspection of some of the most common smartphone security risks is needed.
Most Common Android App Security Risks
Here are some of the typical security risks with Android apps.
A. Input Validation
It is one of the most common attacks that can target entire networks and not just personal use cellphones. It is a technique in which hackers use a combination of letters and symbols to try and brick the system.
What’s really concerning is that the hacker doesn’t have to manually type and enter text into a field since they could write a script that generates code that automatically adds it to the text field in the background.
Such threats are really hard to detect since any unknown app can have this script hidden in its functionality. It is similar to a brute-force attack or an SQL injection code to try to crack the code and gain access to restricted information.
The best way to protect against such attacks is to encrypt all input fields so they don’t allow any scripts to run in them or don’t allow copy-pasted text to work on them. It means the user can only manually enter texts in the string field. Also, set a limit on the number of tries it allows before the system locks itself.
B. Insecure Communication Between Apps
As the name suggests, insecure communication between apps refers to the data that is sent between apps communicating over an unprotected channel or the technique by which the data travels is unsecured.
This app’s vulnerability, when left unchecked, enables hackers to intercept the data and use it for monetary gains or to hold a system hostage. It is one of the most common app vulnerabilities since all apps communicate over a client-server method.
The sensitive data transmitted this way can include:
- Encryption keys
- Passwords
- Confidential information
- Account details
- Session tokens
- Documents
- Metadata
- Binaries
This data could be coming to the device from a server, going from an app out to a server, or transmitted between the device and another device for example over Bluetooth.
There are a few key strategies to protect your data from this vulnerability. Firstly ensure the data transmitted between apps goes through an encrypted network. Thus use SSL/TLS transport layer to transport data.
If the mobile app transmits sensitive information, session tokens, or other sensitive data to a backend API or web service using this layer, it is much more secure. And to ensure the SSL/TLS layer has proper certification of security, ensure that it was signed and verified by a trusted certification authority (CA).
It is why it is important that you download apps that have met these security regulations and do not compromise data privacy.
C. Insecure Data Storage
Insecure data storage results when apps store sensitive data as plain text. This data can range from usernames, passwords, credit card information and banking details, etc so it is highly imperative that such data be saved securely at all times.
In web and server-based applications, developers may use databases or saved settings to store this type of data; however, this does not always work in mobile applications. The developers assume that users or malware will not have access to the mobile device’s filesystem or sensitive data, but the file system is easily accessible.
Developers should anticipate a malicious user or malware examining sensitive data. Refrain from using insecure encryption mechanisms because jailbreaking or rooting a mobile device will circumvent its security. When data is not properly protected, many tools are used to view the application data such as a mobile monitoring app.
To protect against insecure data storage techniques, use encryption and hardware that comes with backup and built-in security techniques. Also, use proper data authentication techniques like user credential registration and user privileges by enabling data restriction so only users with relevant access rights can view the data.
Conclusion
Android security varies from device to device too. The latest Android updates and security patches are delivered first to flagship phones and Google Pixel phones. It makes flagship and high-end smartphones more secure than mid-tier or low-cost smartphones.
Bug fixes and user interface enhancements are packaged by Original Equipment Manufacturers (OEMs). These, however, are insignificant enough to have an effect. Or they arrive far too late to prevent preventable security breaches.
But with the right security tactics and caution, these techniques can make even lower-end Android devices much more secure than before.
