Reviews for the Blu F91

BLU F91 Smartphone Review
Source: OI Spice Tech News English EN→zh-CN
The BLU F91 smartphone is a deal breaker if you are looking for a decent and affordable 5G connectivity. Besides this, the phone also delivers great specs according to the price segment and renders immersive customization features to enhance the overall user experience. But at the same time, there’s no denying that the phone has an equal share of downsides. It doesn’t have the latest Android update and the company won’t give a clear answer about future updates. Aside from this, you can only casual games, while it doesn’t have exceptional camera quality. To understand better, you can also check out other alternative options such as the Oppo K10 which comes with better specs and price range, compare and make the final call.

76% BLU F91 5G review
Source: Android Guys English EN→zh-CN
The BLU F91 5G continues BLU's legacy of offering high value proposition devices with budget-friendly prices. As an unlocked phone that works with AT&T, T-Mobile, and their respective MVNOs and prepaid brands, it's compatible with a large number of carriers. For your money you get more than enough hardware to last most users the next two years. It doesn't approach flagship-level performance and it doesn't have all the fancy accoutrements that come with such phones, but if you've never had them, you don't know what you're missing. I suspect the target audience will be very happy with the big screen, long-lasting battery, and numerous camera modes. And adding in small things like a headphone jack, NFC, wireless charging, and an intentional design make the F91 5G even more compelling.
