Buying a second-hand smartphone is a great way to save money, but not all used phones are a smart investment. One of the most important factors to consider is software support. A phone with outdated software can miss out on security patches, new features, and app compatibility. That’s why using Android phones with long-term support is essential for both performance and safety.
In this article, we’ll explore why long-term support matters, which brands offer it, and the best models you can confidently buy second-hand today.
Why Software Support Matters in Used Phones
When you buy a used phone, you’re not just buying hardware—you’re also relying on the manufacturer’s commitment to updates. Phones without regular updates become vulnerable to malware, hacking, and app incompatibility. This can lead to performance issues, poor battery life, and security risks.
Choosing used Android phones with long-term support ensures you receive important system updates and security patches. It also means your device can run the latest apps smoothly without slowing down or crashing.
What Is Long-term Support in Android Phones?
Long-term support refers to how long a phone will receive major Android updates and security patches after its release. Typically, manufacturers offer 2–5 years of support, depending on the brand and model. Some premium Android phones now even get up to 7 years of updates.
For buyers looking into used Android phones with long-term support, it’s important to know the release date and check how much support time is left. Even a 2-year-old flagship phone might still have 3–4 years of updates.
Best Brands Offering Long-term Android Support
Not all smartphone brands offer the same level of software support. Some are far more reliable when it comes to long-term updates. Here are the most trusted names:
- Google Pixel: Known for the fastest and longest support, Pixel phones get 3 years of OS updates and up to 7 years of security updates (Pixel 8 and later).
- Samsung: Offers 4 years of Android OS updates and 5 years of security updates on most recent Galaxy S, Z, and A series phones.
- OnePlus: Flagship models like the OnePlus 11 and newer offer 4 years of Android and 5 years of security updates.
- Fairphone: Aimed at sustainability, Fairphone offers updates for up to 6–7 years, making it an excellent eco-friendly option.
If you’re searching for used Android phones with long-term support, these brands are your safest bet.
