My Choice
If I were choosing between these two phones, I would absolutely choose the vivo iQOO 12.
Here's why:
- I prioritize performance: As someone who frequently uses demanding apps and enjoys mobile gaming, the Snapdragon 8 Gen 3 chipset and ample RAM on the iQOO 12 are essential for a smooth and enjoyable user experience. The A02 will be completely unable to handle any demanding use cases.
- Display quality matters: The AMOLED display with a 144Hz refresh rate and high brightness on the iQOO 12 provides a superior visual experience, which is particularly beneficial for gaming and multimedia consumption. This is especially true considering the A02 doesn't even specify its brightness, implying that it may be difficult to use in sunlight.
- Camera versatility is key: The multi-lens camera system on the iQOO 12, coupled with its advanced features, enables me to capture high-quality photos and videos in various situations. I would value the telephoto and ultrawide lenses, as well as advanced features like OIS and laser autofocus.
- I am willing to pay for quality: While the price difference is significant, the features and performance of the iQOO 12 more than justify the higher cost for my personal use case.
- Future-proofing: The iQOO 12 comes with the latest Android version, supporting many years of software updates. The A02, on the other hand, is already running an older version of Android.
The Samsung Galaxy A02 would feel like a major step down, and a source of frustration due to its slow performance and limited features. The iQOO 12 provides a premium experience that I would value highly. The massive difference in chipset capability alone is enough to easily decide the winner.
