OPPO A78 5G September 2025 Update it’s 1GB only for security patch!
Just this morning, my OPPO A78 5G notified me for a new update! As someone who uses its phone every day, I always pay attention to updates, especially security ones because they keep my device safe, and reliable.
The update comes with the version number CPH2483_15.0.0.1300(EX01) and has a size of about 1.13 GB. It may not bring flashy new features, but what it does is equally important, it integrates the September 2025 Android security patch to enhance system protection.

The OPPO A78 5G was officially announced on January 7, 2023 and for me, It’s one of midrange phones with good performance for the price, especially for users in Asia who want a solid performance without spending too much. Powered by the MediaTek Dimensity 700, it comes with 8GB RAM, 128GB storage, a smooth 6.56-inch 90Hz display, a reliable 50MP dual camera setup, and a big 5,000mAh battery with 33W fast charging. I like it because it feels dependable in daily use whether for browsing, social apps, and it proves you don’t need a flagship to enjoy fast 5G and a well-rounded experience.
I’ve been using the OPPO A78 5G for quite a while now, and one of the things I appreciate about OPPO is how consistent they are with updates. This phone is still running smoothly, and with every patch, I feel more confident in its performance and security.
