    • Great phone
Great phone, in excellent working conditions and looks great.

    • It's held up for a year now
Update: lasted 14 months and then top half of screen stopped respondong to touch and black mark appeared in the crease of the left corner. Time to buy a new phone. This was RARELY folding the phone. So if you plan to fold it a lot i dont think it will last very long. I've had it for about a year now and it's still going strong. I read that people had issues with it cracking over time where it folds but I stopped folding it unless necessary like using as a flashlight to read at night or any other rare occasion I need to fold it. It's still worth having a folding phone because of those instances when a normal phone wouldn't work well. But yea I can't attest to if it cracks over time due to the fact I don't fold it often. There are tiny plastic pieces sort of popping up on each side where it folds though,its not bothersome at all and doesnt affect the functionality of it though. I also don't use a screen protector and have dropped it many times and it hasn't been damaged. I do use a phone case though so I'm sure that helped. I recently got one stuck pixel which is annoying but other than that its pretty much the same as it was when I got it a year ago so its holding up we'll. I would recommend this phone. ... show more

    • All tthey sell are DEFECTIVE Phones
bought a phone from this company TWICE. The first one wouldnt stay powered on and the second the mic wasnt working lucky enough. I was lucky enough to get it replaced but the second one was too close to the persons bitrhday so i wasnt able to inspect it fully the phone powered on and worked fine. it when i called the person when they were at the airport did we realize the phone mic was not working. 2 times i was sold a defective phone from this company and they have no remorse for selling crappy half done not properly fixed devices. This is a good phone. Biut hard to repair. I shouldnt have to buy a phone just to have to pay more money for someone to fix something that shouldve have already come in good condition. Absolutely dissppointed and annoyed - then have the nerve to offer 5% partial refund for a device they sold that doesnt even F****** work ... show more

    • Sensitive screen. Buy a case for this phone!!!
LOVED this phone! I dropped it once and the screen completely broke. If you get this phone, you really need a case that protects it.

    • Excellent Condition
I ordered the purple bora version of the Samsung Galaxy Zflip 4 & it came on time in excellent condition like the description said. It only has a couple barely noticeable, miner scratches on the hinge & one on the top left corner. The screen is in perfect condition & everything looks great after finding a good Zflip case for it πŸ˜ŠπŸ‘πŸΌ The phone runs great & has more space than my S32 which I replaced with this phone. I will mention the description said it was factory unlocked, but I got an AT&T locked phone, but luckily AT&T is my provider so I got lucky πŸ™πŸΌ Overall I love this phone it's so cute & I can fold it up to fit nicely in my pocket πŸ₯°πŸ€— ... show more

Thanks God that my phone came in good condition with no scratches. It looks literally new. The issues is the battery life, but the good thing is that it charged really fast. The performance is great, but I have noticed that there are some bugs when I try to use YouTube. It appears my cover reloj for micro sec, but it doesn’t bother me. What I didn’t like is that it came in a really thin package, it could have been broken anytime during shipping. I was lucky that the Amazon delivery was in a good mood. I will updated my review after couple of months if it is still working. At the end it may or may not work. So far, I love it! 11/2/2023 Still working perfect. πŸ’ͺ 1/1/2024 Still working perfect πŸ‘Œ 04/30/2024 Working excellent, I just love my phone πŸ‘Œ ... show more

The phone came a bit damaged the left plastic bumper was not there only the right one. The cover screen had a small scratch. The phone is amazing. Its fast, you can wireless charge other devices which i love that. If you want to buy this phone you should but u should buy it at other places, this company is not the best nor its the worst. The phone is very lightweight and is very compatible. When using the phone you dont feel the screen when your using it. The lock on this phone is amazing. ... show more
