Samsung Galaxy A02

The Samsung Galaxy A02 is a budget-friendly smartphone that fails to deliver on its promises. Despite having a quad-core Mediatek processor and 3GB of RAM, the phone's performance is sluggish, making everyday tasks like web browsing and app usage frustrating experiences. The phone's camera, display, and battery life are average at best, but it's the poor performance that really stands out as a major issue. Even simple tasks like loading apps or browsing the web become long-winded processes, making it feel like a chore to use the phone. What's even more puzzling is that when you do finally manage to get into a game, it runs surprisingly smoothly. It's a strange paradox where the phone can handle demanding games but struggles with everyday tasks. This inconsistency makes no sense and only adds to the overall frustration of using this device. In terms of specifications, the phone has a 4-year-old quad-core Mediatek processor and either 2 or 3GB of RAM, which is not impressive compared to other devices in its price range. The Geekbench scores are also underwhelming, putting it at the bottom of the list among recent phones. Overall, the Samsung Galaxy A02 feels like a phone that's been left behind by time and technology. Even considering its low price point, it's hard to recommend this device when there are better options available for the same or slightly higher cost. The a02s and a12, both more expensive than the A02 but still budget-friendly, offer far superior performance, cameras, and features. Unless Samsung releases some significant software updates in the near future, it's best to avoid the Galaxy A02 altogether. Instead, consider one of its better siblings or other devices from different manufacturers that can provide a much smoother and more enjoyable user experience.

realme C21

The Realme C21 is a budget-friendly smartphone that packs some impressive features, including a massive 5000mAh battery, a 6.5-inch mini-drop full screen, an instant fingerprint scanner, and a 13-megapixel triple rear camera setup. The phone's design is sleek with a geometric pattern at the back, providing a good grip and resistance to fingerprint smudges. The volume rockers and power button are located on the left side, while the sim tray and micro SD card slot are also accessible from there. Under the hood, the Realme C21 is powered by a Mediatek Helio G35 chipset, paired with 4GB of RAM and 64GB of internal storage. While not the most powerful processor, it manages to deliver decent performance for gaming and everyday tasks. The phone runs on Realme's User Interface 1.0 based on Android 10, which is simple and efficient, consuming less resources while performing well. The display is a 6.5-inch IPS LCD panel with DUV rain land certification, offering good viewing angles and a surprisingly smooth experience. In terms of performance, the phone can handle games like PUBG and Call of Duty at medium frame rates, but may not be the best choice for serious gamers, as other options in the same price bracket offer better processors. The battery life is impressive, lasting two days even under heavy usage, but charging speeds are relatively slow. The camera setup is decent for its price segment, offering a 13-megapixel rear camera and a 5-megapixel selfie shooter at the front. Indoor performance can be noisy and grainy, but outdoor shots are better quality. Overall, the Realme C21 offers a solid package of features and performance for its price, making it a good option for those on a budget.
