    • My Samsung Galaxy Z Fold 4 looks and works great!
Service provider: Unlocked Color: Graygreen Size: 512GB
I'm seriously loving this phone. I'd been eyeing a co-worker's phone for a few years, and when I belatedly realized my Note 9 (which I hardly ever used) was no longer supported, I went for this right away. I think my only disappointment is that the S-Pen doesn't work the same on a Z Fold as it does for the Note. I'm happy with the screen, the battery life, the storage, the reception (not the best where I live, but this phone makes the best of it), the way the apps run, and the feel of the phone--although I keep it in a case, because I drop everything. I've yet to take more than one photo in it, but that one was fine. I may be firmly in the Apple walled garden, with my iPhone, Apple Watch, Apple TV, iPad, and MacBook Air, but I hardly use my iPhone anymore; it's now kind of just there to make certain features work on its fruity Companions. Some of my relatives who saw my phone over the holidays liked it. They lost interest when I answered their questions about the price, but my point is they were intrigued by my phone! If I could, I'd take off half a star for the way Samsung nerfed the S-Pen, but that's not an option. I don't think the loss of that functionality is worth a whole star, so it gets five in my book. ... show more

    • DO NOT BUY A SAMSUNG FROM AMAZON RENEWED - WARRANTY DISPUTE NIGHTMARE
Service provider: Unlocked Color: Graygreen Size: 256GB
I purchased this phone and have been using it for 5 months. All of a sudden the front screen started flickering on and off randomly. This was NOT after a drop or any kind of physical misuse. Over the next three days the flickering became worse and then on the fourth day the main folding screen went black - completely dead. I attempted to factory reset to see if that fixed the issue - no go it would turn on for less than 30 seconds, then hiss static loudly and shut off. While I was trying to verify my warranty it stopped making notifications, then it also stopped making calls, then it stopped being able to take calls... This phone all of a sudden after 5 months of regular use suffered what can only be described as catastrophic hardware malfunction. Over the next 3 days I was contact with Samsung customer service, sending over my warranty documentation more than 5 times - I kid you not. The issue is that the amazon renewed warranty is 90 days and for some reason that overrides the fact that the phone has a year long warranty through Samsung. I sent my documentation five times to three different agents and even though it showed as in warranty on my end (from the original documentation i sent through the website) each agent somehow could not see that the documentation that I sent in. I spent over a week with Samsung customer service arguing the fact that they were incompetent and my warranty was valid. Now I am still in a fight as it is showing a repair estimation and still showing as out of warranty - whether through the amazon renewed warranty issue or whether they're sayin it's physical damage (I repeat the phone has not been dropped, the catastrophic issues started randomly) I will never buy another electronic from Samsung - Their customer service is the most appalling thing I have ever experienced - and I will be moving to a different device without repairing my current one if they insist its related to physical damage. ... show more

    • You can choose a screen saver for both screens 🙀
Service provider: Unlocked Color: Graygreen Size: 512GB
I was honestly sceptical of purchasing, as I'd read so many negative reviews. I decided to wait three months before leaving a review. The phone came in mint condition, no scratches, dinges or loose parts. SIM tray was easy to pop out, battery life lasts over 24 hours of usage varying from podcast listening and scrolling through social media apps. The quality of this phone is great. I was scared after seeing how glitchy and prone to breaking the Fold 3 was. Thankfully I spent an extra $50 on this model. It fits in female and male trouser pockets perfectly. As advertised, it truly is an unlocked phone! I tried AirTalk wireless SIM and it worked flawlessly and H20 Wireless. ... show more

    • Nice phone and good customer service
Service provider: Unlocked Color: Graygreen Size: 256GB
Almost one month ago, I bought this phone and have been using it regularly. Overall, it is working well. 1. The phone looked 100% new when I received it. 2. The battery performs excellently; after charging, I can use it for a day and a half. I did encounter a small issue with the system because the phone was locked by the admin. I contacted Amazon and the seller's customer service, and they were very friendly and helpful in resolving the issue. If they couldn't fix it, they offered to arrange a return and refund. In the end, everything is working well, and I appreciate the great service I received. I love it! Thank you for your assistance! ❤️❤️❤️ ... show more

    • Never again
Service provider: Unlocked Color: Phantom Black Size: 512GB
I purchased this Galaxy Z Fold from thegadgetdeals. I was excited because this is a really cool phone. I got it and visually it was in good condition, it even came with a s reen protector on the inside screen. But then I noticed that it wouldn't charge wireless. 9 then noticed that the screen protector was coming g loose. After that I noticed what looked like a hair on the screen screen, it wouldn't blow off so I figured it was under the screen protector. I lifted it up and the hair didn't move, it later got bigger. I requested a refund and got it. The seller said it was a damaged pixel then charged me a restocking fee for a phone the clearly needed repaired. Accused me of dropping it cause they said the camera lens protector that I put on was cracked. Therefore even more proof, in their eyes, that the phone wasn't returned in the condition it was shipped. I will never buy from them again. And will tell my family and friends not to either. ... show more
