1. Are Mobiistar phones worth it?
1.1. Evaluating Mobiistar phone designs
All Mobiistar smartphones boast trendy designs, following current fashion trends. While lacking groundbreaking style, Mobiistar's models typically feature rounded edges, luxurious metal backs, and well-positioned front and rear cameras for user-friendly usage. Despite primarily targeting the budget segment, some products are equipped with convenient rear-mounted fingerprint sensors. Overall, Mobiistar smartphones offer appealing, elegant designs.
Certain Mobiistar models exhibit clever designs with metal backs juxtaposed against plastic frames coated in faux-metallic paint. The meticulous craftsmanship ensures comfortable handling and usability.
The physical buttons, including the power button and volume controls, are well-placed and responsive, offering a satisfying click. Their positioning is ergonomic and user-friendly.

1.2. Operating System
Most Mobiistar products come with the Android operating system, developed by Google. This open-source OS is designed for touchscreen smartphones. Mobiistar devices typically feature a user-friendly interface that is easy to adapt to and customize, catering to various user preferences.
While Android OS offers numerous advantages, it also has drawbacks such as background apps consuming RAM and causing lag or freezing. These apps are regularly updated via the Play Store, which may inconvenience users. However, users can customize update settings in the Play Store according to their needs.
1.3. Configuration – Performance
Mobiistar smartphones often feature decent configurations. For instance, the Zumbo S2 model utilizes a MediaTek MT6737T quad-core processor clocked at 1.4GHz, Mali-T720 GPU, 3GB RAM, and 16GB internal storage expandable up to 64GB via external SD card. While not high-end, this configuration adequately handles most tasks and serves basic user needs well. Mobiistar devices also provide smooth gaming experiences for low to mid-range games.
Mobiistar typically equips its devices with HD screens or higher, utilizing IPS LCD technology for excellent display quality and high resolution. Images on Mobiistar products are well-reproduced, sharp, and exhibit true-to-life colors. However, the screen brightness tends to be slightly higher compared to other products in the same price range. If you're wondering about the durability of Mobiistar phones, the answer is that the product quality is average and commensurate with its price.
1.4. Features
Mobiistar smartphones, running on the Android operating system, offer various features such as multitasking, customizable interfaces, and quick message replies directly from the notification panel. Additionally, the app store, Google Play Store, offers a wide selection of apps regularly updated for users to enjoy on Mobiistar devices.

1.5. Connectivity
Most Mobiistar smartphones support dual SIM slots and a dedicated microSD card slot. These devices also support 3G, 4G LTE networks, Bluetooth, and Wi-Fi for high-speed internet experiences.
1.6. Camera
Mobiistar places great emphasis on both front and rear camera systems. The company typically equips its products with high-resolution cameras and the latest advanced image processing algorithms. Photos taken with Mobiistar devices are characterized by high sharpness, vivid colors, and authenticity. Additionally, the front camera integrates various editing and beautification features for stunning selfies.
In reviews assessing the quality of Mobiistar products, the photo quality is consistently rated highly compared to other products in the same price range. The autofocus capability and noise reduction in low-light conditions are also commendable. It's fair to say that the camera is often a standout feature for these devices, addressing consumers' concerns about whether Mobiistar phones perform well.
1.7. Battery Life
The battery capacity of Mobiistar phones typically ranges around 3000 mAh, sufficient to meet regular user needs. With this capacity, the device can last from five to eight hours with basic usage such as calls and light entertainment. However, under heavy usage, the battery life may range from 2 to 3 hours.
1.8. Price Range
Mobiistar focuses on the budget segment, hence the prices of its products are relatively affordable. With just over 1 million Vietnamese dong, you can own a brand-new Mobiistar device. Some Mobiistar products, even upon release, are priced below 5 million Vietnamese dong, making them very budget-friendly options for consumers with limited budgets.

2. Choosing Between Mobiistar Zumbo S2 and E Selfie
2.1. Review of Mobiistar Zumbo S2
The standout feature of Mobiistar Zumbo S2 lies in its front camera, boasting a 13MP resolution for exceptional selfies, making it a budget-friendly selfie-centric smartphone. The camera interface is simple and user-friendly, particularly appealing to selfie enthusiasts. The design combines metal and faux-metallic plastic, imparting both elegance and improved signal reception compared to solid metal designs. Despite being a budget product, the fingerprint sensor of Mobiistar Zumbo S2 exhibits sensitivity comparable to higher-end models. Running on Android 7.0, users can enjoy a plethora of utilities. Zumbo S2 is often cited as an example when users inquire about the performance of Mobiistar phones.
Mobiistar Zumbo S2's main drawback lies in its average performance. Targeted towards selfie enthusiasts, its 16GB internal storage may feel limited. The display colors are somewhat muted instead of vibrant. The 3000mAh battery may not suffice for most users, and the absence of fast charging may inconvenience users.

2.2. Impressive Features of Mobiistar E Selfie
The first highlight of Mobiistar E Selfie is its solid metal design, providing a visually appealing and sturdy feel. The back panel features metallic gold accents, creating a harmonious overall look. The arrangement of the camera system and flash on the back panel is well-placed. Another advantage of E Selfie's design is the placement of the charging port and external speaker on the side, allowing users to charge while gaming without tangling wires. The 6-inch screen offers an excellent entertainment experience. The 13MP front camera, coupled with beauty features, appeals greatly to female users. The 3900mAh battery capacity is another plus, extending usage time.
A drawback is the modest specifications of the device, resulting in mediocre performance. While the display quality isn't terrible, the screen refresh rate is slightly low. However, this drawback may go unnoticed by all but the most discerning users. Another downside of the E Selfie is that despite the 6-inch screen extending to the edges, the manufacturer still opted for thick bezels at both ends, diminishing the device's elegance.
