If I could give a minus rating, believe me, I would. I've had this phone a little over a month. The phone has never been dropped or damaged by me in any other way & I'm the only one that's touched the phone. Clearly, the phone had issues, most likely when I got it but just hadn't become visible yet. It should have lasted WAY longer than a month & 5 days. Now the seller is refusing to stand behind it, saying I damaged it. I'll never buy anything from this seller again.

This review is for the phone as well as the process of buying a Renewed item through Amazon. I purchased this phone because I could not find a phone that isn't massive but that still had the features and performance I require for daily use, so I decided to try this renewed Flip 4. The 90 day return policy and the great price convinced me to try it out. Not sure if I can name the seller in the review but I basically selected the phone in the best condition from the highest-rated seller fulfilled by Amazon. The phone arrived in blank packaging with a charging cable. It looks like there is a screen protector installed, plus there was a plastic film on top of the screen for packaging. It came half charged. The phone itself looks brand new. No detectable blemishes or signs of use. Hinge is nice and solid. Full charge was very fast (with fast charger). Setup fairly easy with Samsung transfer app but I am still missing a few passwords and accounts. I can manually add those later. There is a lot of bloatware from Samsung, plus carrier junk apps. (I think this is carrier unlocked- when I put my SIM it, it applied my carrier settings and apps.) Battery life (as expected-lots of info on this) is not great. I knew that going in. I am tracking battery usage throughout the day with different levels of use- screen open and closed, dormant or playing videos - and it seems as though this particular device doesn't deplete battery any more than would be typical for a phone this age. I suspect this particular phone was very gently used to begin with. Example: battery depleted about 10-15% overnight with no use, not plugged in. With heavier usage the battery use goes up to about 10% per hour. Not sure if there's anything I can adjust/disable to make this more efficient. My old phone would give me 1.5 to 2 days of a charge with regular use so this will be an adjustment. The screen is beautiful and easy to see. Samsung is an upgrade overall for me and I am pleased with how smooth it runs. Nice on-screen keyboard, etc. I am not tech savvy so there are probably too many customization options for me personally. I really just want a phone that works well for calls, that I can text on and use internet and maps periodically. This should do the job just fine. No SD storage and no headphone jack. I guess that's becoming customary. The device doesn't seem flimsy at all. That being said, I would get a case ASAP in the event of inadvertent drops - it happens. Signal and connection seem good, as does speaker quality. The fingerprint sensor is on the side near the volume buttons. Not sure I am crazy about this placement and it never registers the first time for me, but I think that's probably a user (me) problem. Overall I had a very good experience buying Renewed. Anyone who is interested in trying a flip smartphone, this is very economical option without a major commitment. I will update my review accordingly if, within 90 days, anything goes haywire on the device.

I want to say that I love the phone I got! Other than a little problem at the beginning with the phone not being unlocked but the company was awesome about the problem! They sent me a replacement & this one is very good! It looks good. I put my SIM card n & it worked perfectly! There's a little wear mark on the screen but u can't tell while it's lit up. I am very happy with the product & the seller!

This sleek and stylish foldable phone has managed to exceed all my expectations, offering a perfect blend of speed, economy, feature richness, and outstanding battery life. Let's start with the design. The Z Flip 4's compact form factor is not only a marvel to behold but also highly practical. The folding mechanism is smooth and precise, reflecting the cutting-edge engineering that Samsung is known for. The device fits perfectly in the palm of my hand when folded, and its slim profile easily slips into my pocket, making it incredibly portable. The speed of this device is nothing short of impressive. Powered by the latest hardware, including a snappy processor and ample RAM, the Z Flip 4 handles multitasking with ease. Apps launch quickly, and navigating through the interface is a seamless experience. Whether I'm streaming videos, playing games, or working on productivity tasks, the Z Flip 4 delivers a fluid and responsive performance. Economical in both price and energy consumption, the refurbished Z Flip 4 proves that sustainability doesn't have to come at the expense of performance. The refurbished model not only comes at a more budget-friendly price point but also contributes to reducing electronic waste, aligning with the growing demand for eco-conscious consumer choices. One of the standout features of the Z Flip 4 is its impressive array of capabilities. The camera system, for instance, captures stunning photos with vibrant colors and sharp details. The ability to flex the device at various angles unlocks creative possibilities for both photography and video recording. The flexibility of the foldable screen also enhances the overall user experience, allowing for innovative use cases in both entertainment and productivity. Speaking of the screen, the Z Flip 4's display is a visual treat. The vibrant colors and high resolution make watching videos or scrolling through social media an immersive experience. The durability of the foldable glass ensures that I don't have to worry about scratches or cracks, providing peace of mind in daily use. Now, let's talk about battery life—a crucial aspect for any smartphone user. The Z Flip 4 excels in this department. The combination of a well-optimized operating system and a sizable battery ensures that I can go through a full day of heavy usage without worrying about running out of power. The quick-charging feature is an added bonus, providing a significant boost in a short amount of time. In conclusion, the refurbished Samsung Galaxy Z Flip 4 is a triumph in smartphone design and functionality. Its seamless folding mechanism, powerful performance, economical pricing, feature-rich capabilities, and impressive battery life make it a standout device in the crowded smartphone market.
