Top Amazon Reviews
As a PC tech of 30 years, I am a tough sell for any electronic product. After dropping a $900 Samsung on the driveway, mind you a soft drop from a height of 24 inches as I sat in the sun on a low recliner.. I decided that I really do NOT need overly-priced phones that can do things I do not need. Samsung surely has the market on high quality photos, but in 2023, how much worse can a high end lower tier phone be when it comes to photos. My next move was to Motorola. After 9 years of that, I learned low end Moto phones, if you drop them, forget repair. They do not want to touch them. At the end of 2022, I decided on a new strategy. First, I got a Wells Fargo credit card that had phone replacement warranty when I paid my monthly cell service with the bill. Then I dropped Mint Mobile for a cheaper service using Hello Mobile. Hello works best if you have WiFI at home. I get away with $10 a month because I work from home and maybe do 10 hours a week outside the house. Next I read ALL the reviews on phones that cost under $400. And then found tons of YouTube and independent reviews that said this phone was incredible value for the money. I thought perhaps this was too good to be true, but figured, when ordering by Amazon, what do I have to lose? Even after 4 months of owning the Blue F91 5G.. I am still totally blown away. Let us also mention that I ordered this for $230 plus tax... and I almost feel guilty I paid so little. Here is short summary of features that amaze me - Fingerprint reader took a while to set up, but worth it. Phone resumes near instantly, with right hand click on clear button. - Reboot is fast compared to previous phones I owned - Internet surf speed is fast - Daily phone apps, like OfferUp, WinnDixie and banking email apps are quick responsive - I get helpful world news updates from Gmail news automatically - Blu gives you a protective outer cover for free. I usually hate phone covers, but this one is perfect - Weight and large 6.8 inch size is perfect for me (even though my hands are small for a guy) - Charging speed is great, even of charging stands that are not that powerful - One charge can last a full day of use. I drain my battery because I have info apps on all the time. Negatives - sound volume up and down buttons (left side) are positioned too low. I accidentally lower the volume just by normal handling of the phone. I learned to check my volume often. Why didn't Blu realize this? - if you are heavy feature customizer, you will need to Google for support help. The phone is not that user friendly. I struggled with small glitches setting up unique, assigned ring tones and notifications for different apps. Most of the fault lies on the shoulders of the OS, but Blu could have done more to improve on this. Using Google to finding tutorials from other Blu owners solved the issues, but none of the solutions were intuitive. Summary: Blu is a relatively new player that is the best kept secret in the industry. You should also note that Blu is a MIAMI FLORIDA company. Go USA!

...and can't be modulated (which might not ever be a problem if you don't routinely power off the phone at night, like I do). UPDATE (4/23): If you don't want to alarm the dog or wake the house, turn the "Ring & notification volume" setting to nil/0 before shutdown (to mute both off and restart chimes. But remember to re-raise volume as needed during waking hours). Also, the generally OK camera is a bit limited in some of its capabilities. If I switch to wide angle lens (i.e., magnification below x1.0) then picture is always underexposed, even with flash on. Variable exposure control in "Pro" mode is too hard to access and regulate for backlight compensation, etc. Full-frame dimension (16:9) is not available in wide-angle, portrait, or macro mode (only 4:3). Perhaps most annoying is Blu's lack of camera documentation: I still have no clue about how/when/why to use some of the "More" menu options, e.g., "108MP", "Gif", "Intelligent Scanning". Under settings, there's no explanation about when/why "anti-flicker"; also, "HDR", "AI" and other menu symbols aren't defined or explained. User manuals on Blu's website are bare-bones regarding camera functions, leaving the above functions unexplained. Volume control for phone ringer and notification chime is unified; I'd prefer those functions be separate so, e.g., call ringer could be loud while notification chime be less so. The phone is often very slow to recognize and switch between the two different wifi networks/zones I use (for upstairs/downstairs), though it holds wifi signal well once connected. Overall, however, this is a very good phone, a huge improvement over my decade-plus-old Galaxy J320a.
