Can't beat it for $199 or even $249
This is my third BLU phone and the best one yet. This is a long review, but this phone and BLU deserve it The lcd screen is very clear and bright, even decent in bright sunlight. The camera uses a Samsung sensor and the picture quality may not match a $1,000 phone, but I've been extremely pleased. It has a very good 4x zoom lens, macro pictures come out great, and the night shot setting is very good, but those pictures are a little grainy. The integration of the on-off button and actually a thumb print sensor work perfectly and very fast. Blue tooth pairing and internet pick up are quick and smooth. The 8gb memory, 128gb storage, with an available microsd card holder, a 5000 mamp battery, match or are better than most $500+ phones. My main reason for buying this phone was waiting for any 5g phone to come out at $300 or less. I still had a BLU g8pro that worked fine, then Amazon sent me an email this phone was on sale for a short time for $199, I bought it that day. I have TMobile service and the 5g speed is fantastic, I've run a number of OOKLA speed tests, with the lowest download speed of 180mbps to a maximum of 710mbps, and that's not a typo. It switches flawlessly from 5g to 4g lte then back to 5g as you move from a 5g tower to one that only supports 4g. I didn't know why this happened, thought it may be the phone, so I called the BLU service support, and got a technician on the phone within minutes. He explained why the switching happened, it isn't the phone, but the strength of 5g as you move from tower to tower. To strengthen the reason for this 5g phone, T-Mobile has come out with a 5g internet box for the home and just got one, and am waiting for them to get their tower I am on, to get its operating software loaded. I presently pay $80 a month, and going up, to Spectrum for internet and wifi, the internet service from T-Mobile is $50 a month, first month free, AND you don't have to be a T-Mobile customer to get one. It may sound like I work for T-Mobile, but I don't, but have been a customer for 16 years. This has allowed me to purchase every unlocked phone I've ever owned, from Amazon. And fortunately, with their purchase of Sprint, they have the best 5g coverage of either ATT and Verizon. In summary, I don't think there's a better 5g phone for $300 or less available at this time. It's worth a try, buy it, if it's not for you, you have 30 day's to return it. One thing I forgot, BLU gives you a fast charger, cable, screen protector, AND a very nice case with the phone. A $1,300 I-phone doesn't have any of that for free. ... show more

5G Android 11 phone Priced right & Great features.

Review Image by Mister bubbacat
I've been checking out reviews of valued priced 5G phone to replaced my 3 yrs Motorola E5 plus that recently start to shutdown intermittently and won't startup, unless using the Boot Loader sequence Vol Down + Power. After reading online reviews and comparing features, the Blu F91 checks out all the boxes of what I need. I'm looking for More Ram and storage, NFC support, 5000Ma battery for 3 days usage, 5G support and carrier unlocked for GSM network. The MediaTek Dimensity 810 processor's performance is comparable with the Qualcomm Snapdragon 810 used in Motorola 5G phones. The OLED display is as good as the Samsung AMOLED. The touch screen respond is fast and fluid. The package includes a nice carbon fiber like case and tempered glass screen protector, high current fast charger (Samsung makes you pay for the optional charger for their $1,300 Galaxy S22 Ultra !!) and a wired ear bud that doubles as an antenna for the built in FM radio. The SIM adapter support DUAL SIM card for International travel. I successfully backed up my Motorola Android 8 data and restore it to the new Blu F91 Android 11 seamlessly. Blu default install includes a couple of games app that I was able to manually remove without any issues. Unlike most manufacturer, that preinstall Bloatware that are annoying and sometimes NOT Removable, Blu did not. By default it comes with 128 GB of Internal storage and a hefty 8 GB of RAMs compared with the Samsung A53 of 6 GB and Motorola Stylus of 4 GB RAM. I added a $19.99 Silicon Power 256 GB Micro SD and have it formatted as additional internal storage, resulting in a massive 384 GB storage that will last me a long while. All APK were restored from Backup except my MOD Music APK 😁 Android detected and configured the T-Mobile SIM and launch it into 5G mode. Run Speedtest and it consistently clocked at 750~800 Mbps Download and about 250~300 Mbps Upload. All APPs run faster than the Motorola. The Finger sensor built into the Power On/Off button comes in handy to unlock the phone. The Camera features handy pre-set photo mode such as Portrait, Night scene, Wide-angle, Panorama and Macro shot. Picture quality with the Samsung GM1 sensor is pretty good for a budget priced phone. WiFi 6 is support is great, since I've WiFi 6 enabled ASUS Mesh network in my house. The massive 5,000mAh battery last me about 3 days of use and it even comes with Wireless charging found on the more pricy phones. NFC was something that I really like to have, now I can load my Credit and Debit card info onto Google pay and use NFC touchless payment at checkout. Overall, I'm very satisfied with the Blu F91 5G phone. Save more than $250 bucks against the less feature Samsung A53 5G phone. 👍👍👍 ... show more

On/Off chime is too LOUD!
...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. ... show more

Nice fast phone with a couple of short comings
I've come from using some of the biggest names in the cell phone industry. When I seen this phone, I read quite a few reviews and decided to try it. So here's my first impressions of the BLU F91 5G as a daily driver. After unboxing the phone feels of nice quality it doesn't feel cheap. I really like the Blue color. After I was able to get everything loaded I was able to really play with this devices settings and check out it's performance. The screen is nice and makes this phone look more expensive than it really is. Only 60 hz refresh rate. Overall, the usual usage of social and media content is good. I also performed a network speed test on my TMobile network. I'm seeing about 250 download and about 40 upload, which isn't too bad. Web pages seem to load as quick as the big name brands. Call quality is nice and clear. I believe that this phone doesn't support wifi calling. So overall at $230 its pretty good. Now, for the short comings. One of my biggest gripes is the audio is a single speaker and it's not the loudest and the sound is a little thin. It's not terrible but could have been better. On my media player I was able to adjust the EQ to tailor in some better sound which helped a little bit. Stereo speakers here would've really helped this device. The other short coming of this device is the charging speed. While in use the phone takes FOREVER to top off from about 60% with the included 18 watt charging brick. BLU should've upped the charging speed to a minimum of 30 watt charge. Obviously when not in use it will charge faster. Wireless charging is also included with this phone. I like the fact that you can set it on the charging pad and got to bed, and it will be fully charged in the morning. Wifi calling would have been a nice addition. If Blu would have offered this device with these 3 other options, I believe they would've had a phone that wouldve been at the top of the midrange phones rivaling some flagship devices. In conclusion, the Blu F91 5g is a budget phone that targets midrange phones costing 2 times as much. The hardware is pretty good for the $$$. I'm going to make my decision here in the next day or 2 to keep it or return it. I want to give the device a fair shake. I'll edit this post if anything else positive or negative come up with the phone. Edit: My Blu f91 data stopped loading web pages. I went in and reset network settings and that fixed the issue. Then I had to reset network settings again. Then again the day after that. It seems to be a software or hardware issue, so I decided to return the device. It's a shame, because I had high hopes for the device and I really kinda liked it. Demoted to 1 star. ... show more

Value/Price , simple review
This is a simple review for people who wanna know simply would I recommend to buy. Yes. The phone is great quality and performance for the price by far. The only cons I think most people would notice right away is the cameras are mediocre at best compared to more modern phones. However these are usable. Not great but fine. Other than that, I don't see much difference between this and most mid range smartphones in performance. I'd definitely recommend this as a simple cheap Android phone for anyone on GSM networks! I could daily this phone, but going with my iphone 13 if I want photos that don't look like they were taken on a toaster oven. Hahahah. The screen is quite nice and battery holds well. Bluetooth no issues. Wifi and cellular worked right away on t-mobile, phones specs are accurate in CPU x tester. Really impressive for the price point, I've bought phones for 380-400$ that were less powerful and updated. It's definitely something to look into. Edit : I took this device on a trip to the mountains and it can take some pretty nice photos in full daylight. I feel like in nice sunny outdoor lighting it's performance via camera isn't to bad , but indoors or in very low light it's still not it. Just wanted to add this because I slammed the camera earlier. Edit 2: this phone has been so reliable for me. It has worked on every network I've tried it on. Works with my Verizon sim, with T-Mobile as well. The headphone jack has now come in handy!!!! I would say this phone has little to no bugs, more reliable than the pixel 6 pro I just got when it comes to not having bugs. Connection on here is just made easier. Big props to blu. Enjoy ur new phone if u decide to buy :) ... show more

A mixed bag.
I've been using this phone since September of 2022 and this really is a mixed bag when it comes to overall satisfaction. First, let me say that I spent $230 for this phone and for that price what I got I could live with. Currently it's $100 higher and for that price, no way would I purchase this based on what I know now. The Cons first. - The fingerprint sensor is ABSOLUTE GARBAGE. I wanna make this very clear. It fails almost ALL the time when you go to get into your phone and you're left with having to use the PIN. The phone has had a number of patches over the last two years and none of them helped. Removing your fingerprint and reapplying it again or with different fingers makes no difference. - You are most definitely stuck on Android 11. You will get no more OS updates other than 'maybe' some security stuff or bug fixes here and there but if you want an upgrade path - get a different phone. Android 11 is all there is here. - Options for cases is very limited. Since Blu is not well known and is a budget phone that's obscure to most people, choices for cases is not going to be great. You've been warned. The rest of the phone is pretty decent. Nothing stands out in a big way. The 5G is good. The MediaTek Dimensity 810 is a solid SoC. 8G of RAM is solid. 128GB of storage is good along with the microSD card option. Bottom line - for $300+, this just isn't worth it. There are FAR better options. For me, two years ago, at $230 is was a decent choice. ... show more

THese Blu phones ARE THE BEST!!! I have bought 3 now
This phone company is amazing! I just purchased a 5G new one and all 3 phones I own from BLU are amazing. Battery life is off the charts!! I use my phones all day and these keep up. For about $200 ( I bought 2 of the G90 Pro's and now this one), the value is great! I will never buy a phone our service carrier promotes ( samsung,etc). why , these are just as good if not better. Ease of use, design is great. Speed is amazing. Oh, and unlike Apple, samsung $1000 plus phones, these guys throw in a durable phone case! it amazes me that the name brand phones (samsung.apple, LG) cna charge you well over $1000 and not even give at least a good case. the case that came with it is durable and doesn't need replaced. I know some phones come w/ cases that are flimsy, and cheap. Blu is the real deal. And these guys deserve your biz!!! other features, camera is amazing, features are too much list, oh and guess what, it doesn't come loaded with bloat apps like FB,etc and what couple of apps it comes with ( games) you CAN delete and uninstall. Oh and guess what, BLU is made and headquartered right here in the U.S.A !!!! ... show more

PC tech says: Love my Blu for 4 months now, never buying ANY other mid-tier phone after this
Review Image by TechGuru
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! ... show more
