BEST PHONE UNDER 300 HANDS DOWN🔥🔥🔥🔥
I'm a phone head. This phone does everything any phone can do and can do it as good as other phones for a quarter of the price. 512gb with all that ram is different. No lag. Takes good pics and videos and the stereo speakers are not bad. The phone is currently 250. I got it for 300. It's a steal. Buy this as a gift for your people for Christmas. I had it since it came out. The screen looks beautiful as well. Just buy it. U won't regret it. I always had to have the latest flagship phones. I told myself I'll try a economic option to see if I'm missing anything. I'm not. The back mini screen isn't a gimmick either. Happy Holidays. 🎁🎁 ... show more

Outstanding Blu Bold N4 5G!
Review Image by Ljpro
What a surprise! I have owned this phone for only a week and do have many higher end Android phones including a dual screen model. With this higher end Mediatek processor with 8 cores and operating at 2.5 GHz with a 120 screen refresh rate is incredible. Screen resolution is 429 Dpi and is as smooth and fast as any other Android I have with a Snapdragon 888 processor.. With the rear display in the camera area which is multifunctional and outstanding in my view! This phone may be little known about but should be a tremendous hit and a consideration with high-end buyers! I guarantee you will not be disappointed if you should purchase one. Outstanding! * UPDATE 12-21-2025. This phone has far exceeded the performance level of any phone I've even owned above $1,000. After downloading all my banking, investing, flying and misc pgms plus all additional apps I was using previously, are all performing flawlessly! The speed in which this phone performs all tasks and programs matches or exceeds any high-end phone I have ever owned. ** This is also the fastest charging phone I have ever owned the advertising is not misleading. You can go from a 0 to 10% to being 100% charged in approximately 20 minutes and from a 20 to 30% to 100% in no more than 15 minutes! *** The only drawback so far I have found is to have not included a SD slot along with the SIM for additional storage. Even being a power user as I am with hundreds if not thousands of photos with almost as many videos already on this phone I have not come close to exceeding the 512Gb total storage that is in this unit. For those of you that think this could be or would be an issue don't worry about it, you can if you don't already have, buy a small charging port C adapter and plug any SD card into it for additional upload or download data up to any amount of gigabytes or terabytes of data if need be. Easily overcome! Included a photo below of one looks like for only a couple bucks. Ratings for this phone at this time are a full 5 star. ***** Will update again in the future if need be. If you need to buy a new phone at this point in time don't hesitate and you will receive a cell phone that will pleasantly surprise you and exceed every expectation you have! ... show more

I am completely satisfaction sold on the lovely BLU Bold!
Most reviewers of his device on YOUTUBE, rated this device as the BEST Budget phone in 2026. I agree 100% with this assessment. I love the looks, the feel, and the quality build. I like the screen brightness, image sharpness, the overall performance, and the amount of included features, and accessories. A super nice smart device at a very good price! I only wish that I could get 2 or 3 more future OS updates. ... show more

Blu N4
Easy to setup. Thin and not too heavy. I was able to connect to my carrier with ease due to it being an unlocked gsm device. For the price, it's quite snappy. I've purchased several BLU devices over the years and I always enjoy them. Unfortunately you're not likely going to get any Android update support with these phones, though. The screen is bright, maybe a little too much- but the screen is clear and has a great picture. Camera is mid. It does have a decent zoom but can get pixelated when using it to it's full extent. The rear screen is cool, but honestly I never utilize it. I don't like that I can't turn off the AM/PM on the clock, so I just switched to the 24 hour clock. Overall I'm very happy with this purchase and would recommend it if you're looking for an affordable, fun phone. As other reviews mentioned, there is some bloatware on it, which you can disable and/or remove. ... show more

Great phone, but not perfect
I like Blu phones, and this is one of the best that I have had. Very responsive. 5G more stable than my last phone of another brand. Camera is on par with other phones in this price range. The keyboard is slightly more accurate than previous android phones. Battery life is reasonable and charges fast with the included charger. I don't know if it is a Blu custom interface, or changes in Android 15, but everything seems to work differently, so expect days to weeks to relearn how to use the phone, and don't expect the new way to be an improvement. You will not find after market cases or accessories. It does come with a case that is good, but takes some getting used to. The curved edges make a screen protector complicated, which I recommend. Overall I would recommend the phone for the price. Just expect the usual inconveniences of a lesser known brand. ... show more

Seemed great, seems to be slowly spiraling after not even a year of use
**DO NOT PURCHASE, randomly started going downhill... Phone seems to be slowly dying... Was just having random restarts and software crashes... After recent security update phone has now turned to showing the android bios like screen after said restarts and boots, but crashes shortly after booting** Previous Review: Up until now everything has been going smooth on it, but suddenly the past few days, android has been seemingly restarting itself randomly, I have tried everything I can think of, but none of it has worked. Hopefully this can get fixed. Everything runs super-fast, back screen works and looks good, I'm coming from the F91 5G and it is an extremely good upgrade. One thing I would say is that I hope they add more things to put on the back screen *Update* Owned for a few months now, everything still working smooth, the ultra fast charging seems to be the only way it actually charges at night, and still no updates to the rear screen *Update* Owned for almost a year now, the charging port has become a little sensitive as to whether it does the super fast charging or not but it's probably user error, still nothing on the lines of software updates, only security updates get pushed out. At this point, it is a decent phone, especially for the price, but soon they will most likely release a new one with the latest android. Everything is still responsive most of the time, has gotten a little buggy, and have had no problems with apps and compatibility as of now ... show more

Excellent value midrange phone
This is an excellent value for the money. It is a midrange phone with a bunch of nice extras. It has a rear display which can be helpful when talking selfies with the rear facing camera. It includes accessories like a protective case, headphones, and a charging cable and adapter for fast charging. The headphones function as an fm radio antenna, which is not frequently found in devices currently. It performs quite well overall. Would definitely recommend it ... show more
