It’s a Better Than Expected 🤯

Genuinely impressed. It’s huge and handy. I use it as a back up phone and it works well. I think you get what you spend. The camera quality isn’t the greatest but I don’t mind it. The battery last quite a while off a single charge. I usually use it for games or reading for the most part. The screen quality is great too. It’s about the same weight as my iPhone 15 Plus too. I kinda just take it everywhere. Side note ~ The way the phone suggests color themes that match my background was SUPER cute. ... show more

1/5 TONS OF BLOATWARE
Color: Purple
When booting the phone and finishing the setup, it immediately installed 71 APPS, random games, news, social medias etc. and after going through all of them and deleting them all. THEY SLOWLY JUST REDOWNLOAD back onto the phone...flooded with bloatware and sketchy that it just resinstalls the bloatware apps over and over. Kind of unsafe, not satisfied with the purchase. Only thing good about it is that it turns on and works but not happy about all these shady apps. ... show more

Great phone for the price...
Color: Black Blue
I have been buying BLU phones for my wife and I for over 10 years now. We have never had a problem with any of them, now my wife gets a new one about every 2 years where the one I had was every bit of 6 years old it was a G60 and the only reason I replaced it was it was running android 9pie and I needed an update bad. This Bold K12 is really nice and fast and runs the apps I need with android 15. Now I'm just an average user but after 2 days of use I'm between 50-60% battery charge for the week I've had it. The few calls I've had sound nice and clear with good volume and it scoots around on the internet just fine, well a lot better than my old phone. ... show more

not bad at all
Color: Silver
considering price, its a good phone. just got the package and first thing i notice is a ton of bloatware and advertisement based garbage, there should be simple way to remove all of it -there is not ! ive been uninstalling and tweaking the phone since i got it and not done yet. flip side, for using with US Mobile , the SIM is direct plug and play. as well , the phone took extra memory no problem. charge seems to be holding well so very happy here. phone is nice size and comes with extras like the case. has the larger USB-c so be aware. you do not have an easy way to open this phone, which means the SIM and memory card are accessed via the side of the phone. the camera i find it to be very nice... again for the price of the phone the camera is awesome. ive tested the phone with texts and calls, working great. the speed of the phone is good for everyday tasks , i dont play games on it so cant comment. ive installed apps i use and am in the process of on-boarding all my other stuff, still plenty of tweaking to do which is why i gave it 4 stars ...i will update later , you will like the phone , im happy to own it outright & pay only $10 mnth for service with my carrier ... show more

Great Value and Easy to Set Up
Color: Champagne Gold
I bought this as a replacement for my old phone after I lost it, and it has been a great choice. It was easy to set up, and I was able to recover my data from my cloud backup without any trouble. The phone looks great, feels well made, and is surprisingly fast for the price. I mainly use it for texting, calls, and browsing the internet, and it handles everything smoothly. I also appreciated that it came with lots of accessories, which made it feel like an even better value. If you're looking for a good-looking, dependable phone at a great price, I would definitely recommend it. ... show more

My K12 Experience
Color: Silver
I am not sure where to start I brought this phone for my wife. The front face of the camera glitched and had purple lines going through it I could not see her on video chat. Back of the camera sucks I am not even going to lie. When an image did appear it was super dark and she was in the light. I have owned two previous Blu phones and none of them have ever done what this K12 has done. I tried using the phone in the store on video and it did the same thing and frozen. GPS stalled and did not work properly at all had to pull over and reboot phone. After reboot still did not work. This is something I should not have had to do. GPS froze and stopped working in the middle of deliveries, dropping off packages, etc. Good thing we remembered we had another phone and got home safely. We can go on and on with the problems we have had maybe it's just a bad phone. ... show more

Good Bang for your Buck
Color: Champagne Gold
Didn't expect much for under $100 but this one's held up well. Screen is big and surprisingly smooth. Battery easily lasts me a full day, sometimes more. Storage is plenty, and there's a microSD slot if you need extra. Camera's decent in daylight, nothing special in low light, but that's expected at this price. Fingerprint unlock is quick and reliable. Comes with a case, screen protector, charger, and earphones in the box, which was a nice bonus. ... show more
