I have had Blu phones for the past 15 yrs. and I’m coming from the Blu G91s which is 3 yrs. old and still works fine but I wanted to upgrade to Android 14. OS upgrades in Blu phones are non-existent. This is the best yet. Stunning amoled display and all the bells and whistles you would get on the big boys.
PROS: Beautiful amoled screen with edge to edge display, 60-120hz. refresh rate that is customizable. Bright enough to see on sunny day. Very light weight, my purse fells so much lighter now. Very snappy, fast. Charges 20-100% in 40 minutes. Lots of customization settings, but this is probably Android 14 features. Phone calls are very clear sounding.
CONS: Transfering date from old phone does not work well using wired connection. Use bluetooth connection for transfering data and this is completed very quickly. Speakers are good for regular use, but would not listen to music on them. SIM tray is funky and hard to open. It did lose connection when I first installed SIM, but is ok after re-installing. Blu does not have OS updates at all, but does have security updates. Camera is ok, not stunning, but does have all the settings you would get on the expensive phones. No RAW, no image stabalization. Macro is useless. See attached photos. Phone came with a ton of bloatware, and an entire tray of games which can be erased. The large camera circle on back of phone is a bit concerning for scraching, etc. What were they thinking? Phone did get warm, not hot on initial charging, but now is not a problem at all.
So far I am thrilled with my new phone, and highly recommend for someone who doesn’t want to spend top dollar but still get top perfermance and features.

Not my first BLU phone but my first Bold, not a bad option considering whats currently available. My last phone was a BLU F91 5G, which if it was still available I would have just bought another. I can’t reconcile mentally why there is no wireless charging. Seriously, all the reasonably priced options don’t have it any longer. The only reason I “upgraded” was because the battery in my old phone got hot enough to off gas and blow the back of the case off on my old phone so I did not have a ton of time to wait around looking for a new phone.

I have been using this phone for a week and here are all the things I have noticed so far.

1. It does have a dual sim card slot, but an odd one. Its on the bottom of the phone, and very difficult to get out even with the tool they provided, it took a bit of a hook to get it out. Its thicker than usual and the sim card kind of snaps in, because its double sided. You put one card facing out on the top and bottom, new to me after having dozens of phones. Nowhere could I find if it was dual sim in the documentation (Sim1 is on top).

2. Its big enough storage to justify not having an SD card slot. I know nobody is doing it these days, but I have had more phones die than SD cards and a good waterproof SD card can save the day if you have a whole trips worth of pictures on the phone when you dunk it hard enough to kill the phone. But, with 256GB its got enough storage for all my MP3’s and lots of pictures (I travel a lot and am on the water often where I have no service but want to be able to have music on board) plus all my apps. There was a bunch of unnecessary bloatware but not terrible and it was easy to clean up. I am at 41% used before I start taking pictures so its a bit dicey for long term usage.

3. The onboard storage is slow. Unbearably slow. Transferring my files from my Windows or Unix PC was maddeningly slow, regardless of USB cable or which port I used. These are the same devices and cables I use for my old phone as well as an even older BLU G91 Pro and they are both 100 times faster to copy files over USB either to the SD card or the internal storage. It was so slow and unusable that I had to try multiple cables and ports before giving up on moving my MP3’s over by USB and installing an FTP client on my phone. That was the only way I could move anything more than a few small files on or off the phone. Its something that I can overcome but its maddening.

4. It came with a screen protector on it. Its good because there are not a lot of options yet, but I didn’t see that anywhere.

5. The case it comes with is laughable and there are not many options currently and you never know if there ever will be. Honestly for this to be in the Bold line and not have a better case than this is a bit odd. My last 2 phones had the black lightly armored cases that were good enough not to need an upgrade, this one is going back a few years and its a throw away if you can find something better. The first one I have tried doesn’t even come close to having the right openings for this phone even if it fits the general form factor and camera lens so if you need a decent case maybe this is not the right phone for you.

6. The fingerprint scanner is adequate but not great. Its in the screen which is the new hottness, but it doesn’t work as well as my last several low end phones. I have 7 or 8 fingerprints registered to try and help my two fingers work but I have to hold it just right to get it to unlock. It works and I am getting used to it but the back panel and power button scanners both work better for me.

7. Battery life is fantastic and it charges well. It does take a bit more power to do a fast charge but it is very fast and the battery easily lasts me all day. No complaints at all, other than damn I wish it had wireless charging, I mean its 2024 and many, many cars have wireless charging and it would be great to be able to use it. I know it adds heat and I wouldn’t really use it in the summer and its not that fast but if you are driving its nice to just keep it topped off if you don’t want to deal with wires.

8. The screen is just lovely. I really should have lead with this. its the nicest looking screen I have every used, and its very bright and very clear. It is so easy to read I might be in the market for a second one because my wife’s phone screen is terrible compared to this one.

9. Its fast enough most of the time. Fastest phone I have ever had, very responsive nearly all the time. The ram is plenty for an old dude who has way to much open and way to many notifications all the time. The only thing slow so far is the camera, and I wonder if its because the storage is slow. That sucks for me, I have missed several candid shots already and experience has told me this is as fast as the phone will get. I am going to have to slow down myself and see if lowering the resolution will help but as of now the shutter speed is slow enough I have taken several pictures of my feet. I have only taken few a dozen pictures and a couple videos, and while they look really really good on the screen I haven’t tried them on a big screen yet. The camera would also benefit from some form of stabilization but it works well enough for the price point from a quality standpoint.

Overall its a good phone, I wish it had a decent case, and faster camera and storage. It wouldn’t hurt to have an SD card slot. It still sucks to not have wireless charging. I hope BLU brings that one back. Its a great phone to look at and feels good in my hand and for the price its very good.

I’ve been using BLU Products for the last 11 years. I already know what to expect. Good quality. Doesn’t break my bank. Only problem I have is the ‘Home’ doesn’t rotate when you’re in ‘Auto Rotation’ mode. Still a great product that doesn’t break your bank.

Still trying to learn this new phone as it is just amazing how different it functions compared to my old android phone. One item that is really weird regarding this phone, the dial push buttons numbers for making a call are only numbers (no corresponding letters). I have never seen a phone made like this where the alphabet letters are not listed with the corresponding numbers for dialing or entering a pass code. Basically if you need to input any pass-codes on this phone when you are calling someone (opening your phone without using fingerprint or facial recognition but a pass code), and you need to press the phone button numbers, you better remember what letters correspond with each number as this phone doesn’t show the corresponding letters of the alphabet and that is kind of a bummer. Why Blu would you make a phone like this? Only 3 stars because of this.
