Expandable Storage Function

The phone supports expandable storage via a microSD card, allowing users to increase the storage capacity up to 1TB. This is useful for storing large amounts of photos, videos, and other files. Users can easily transfer files to and from the microSD card.

Overall Rating

The UMIDIGI G9 5G is an entry-level phone with a focus on providing a large display, ample memory, and 5G connectivity at a budget price. Performance is adequate for daily tasks, but demanding applications may show limitations. Durability is a concern due to the brand's reliability.

Processor Performance
3.0
The octa-core processor provides adequate performance for everyday tasks and multitasking. However, it may struggle with more demanding applications and gaming. The 6nm manufacturing process helps with power efficiency, but overall performance is limited by the processor's capabilities.
RAM (Random Access Memory)
3.5
The phone comes with 12GB of RAM (6GB physical + 6GB virtual). While the total amount seems large, the virtual RAM may not perform as efficiently as physical RAM. This is sufficient for running multiple apps, but performance may degrade with heavy multitasking.
Storage Capacity
4.0
The 128GB of internal storage is adequate for most users, and the option to expand it up to 1TB via microSD card provides plenty of flexibility for storing photos, videos, and other files. This is a significant advantage for users who need a lot of storage space.
Camera Quality
3.0
The 50MP main camera is capable of capturing decent photos in good lighting conditions. However, the image quality may suffer in low-light environments. The additional 8MP front camera and 2MP macro camera offer some versatility, but their performance is limited.
Display Quality
3.5
The 6.75-inch HD+ display with a 90Hz refresh rate offers a smooth and comfortable viewing experience. However, the HD+ resolution may not be as sharp as higher-resolution displays. The 90Hz refresh rate enhances the smoothness of scrolling and animations.
Battery Life
4.0
The 5000mAh battery provides good battery life, allowing users to get through a full day of moderate use. The 18W fast charging allows for quickly replenishing the battery when needed. Battery life will vary depending on usage patterns and settings.
Manufacturer Reliability and Warranty
2.0
UMIDIGI is a relatively unknown manufacturer, so reliability and warranty support are concerns. There is a higher risk of encountering issues with the phone and difficulty obtaining support if needed. Customer reviews suggest mixed experiences with the brand's reliability.
Cost Performance
4.0
The UMIDIGI G9 5G offers good value for its price, providing a large display, ample memory, and 5G connectivity at an affordable price point. However, users should be aware of the potential limitations in performance, camera quality, and brand reliability.

Frequently Asked Questions (FAQ)

Q.I'm concerned about whether this phone will actually work with my carrier. I use Tello, and one staff confirmation mentioned it only partially works and the support wasn't helpful. Is this a common issue?
A.The staff confirmation you mentioned indicated issues with Tello service, particularly with 5G connectivity and download speeds. It's worth noting that the phone is reported to work partially with T-Mobile in California, but another staff member mentioned that not all SIM cards from US cell phone carriers support this phone because it is an unlocked 3rd-party phone. It's recommended to check the frequencies supported by your specific SIM card and carrier. Some users have suggested manually adding APN information, but it may require some technical knowledge.
Q.I don't want to spend a lot, but I need a phone with good storage. Is the RAM and storage on this phone sufficient for everyday use?
A.The UMIDIGI G9 5G comes with 12GB of RAM (6GB physical + 6GB virtual) and 128GB of ROM, which is expandable up to 1TB via microSD card. Staff confirmation mentions that the storage options are ample for apps, media, and files. Some staff members have noted that 6GB of RAM is a bit less than some other phones, but they haven't noticed a significant difference in performance for day-to-day use.
Q.How is the battery life on this phone? I don't want to have to charge it constantly.
A.The phone has a 5000mAh battery with 18W fast charging. According to one staff confirmation, battery life started out okay (day and a half with light use) but increased substantially by the end of the first week of use (now nearly 3 days with light use).
Q.I like using wired headphones. Does this phone have a headphone jack?
A.Yes, according to staff confirmation, this phone does have a headphone jack. You won't have to worry about your Bluetooth headset running out of battery; you can just plug in an old-fashioned set of earbuds.
Q.I'm not very tech-savvy. Is this phone easy to set up and use, especially with dual SIMs?
A.One staff confirmation mentioned that the phone arrived with no start-up instructions. However, they were familiar with the brand and found it easy to remove the Google junk and install preferred apps. The phone searches for other phones to download from, so you may want to turn that off if you don't want info imported from other devices. Some staff confirmed the dual SIM feature is either 2 nano SIMS or 1 nano SIM and 1 TF slot and to check photos. Also, you must press down on the SIM card slot key to open it. If you encounter issues with carrier compatibility, you may need to update the software or manually add APN information, which could require some technical knowledge.
