BAD EXPERIENCE!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Terrible! I needed to wipe the installers fingerprints off my new TV & I called Samsung for instructions on how to clean and followed the instructions to a T but the screen literally wiped off as I cleaned it with a slightly damp microfiber cloth! I immediately called Best Buy & they did nothing for me because I was outside of their 15 day return/exchange window & I was only outside of it by 3 days!!! I just barely had the TV mounted. They told me to call Samsung so I did, they came out quick but only to tell me it’s not covered under warranty. I bought two Samsung TVs from Best Buy on the same day, I have fingerprints on both & now damage on one. I don’t dare clean them off because of what happened and I’m stuck. I will NEVER do business with Best Buy or Samsung again!!! Be very very careful when cleaning because even if you follow the manufacturer instructions you could cause damage and nobody will care!!!

Disappointed and Done RIP Samsung
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this TV in December 2024, by August 2025, it's completely dead. It doesn't turn on, doesn’t respond at all, and even swapping the power cord didn’t help. Just lifeless. Meanwhile, my 2017 Samsung TV still works perfectly. What happened to your quality? This experience has completely changed my perception of the brand. I won't be buying Samsung again.

Donated to a Smash Room
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’m sad to write this review. I purchased almost 14 months ago. Two months after purchase the motherboard went out. I had to wait 12 days for technician (not geek squad) but thankfully covered under manufacturer warranty. Now the same problem is happening. Warranty is expired. I decided to chuck this lemon and purchased a Sony.

Samsung not prime video friendly
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Don’t buy a Samsung TV if you’re planning on watching a lot of prime video movies or series. Takes forever load buffers all the time eventually freezes up with an error message. If you don’t watch prime video then it’s an excellent TV great picture and sound
No, I would not recommend this to a friendBrand response from Samsung
Posted .Michael,
Thank you for sharing your experience with the Prime Video app. If your app is freezing, not loading, or crashing, you can try cold booting your TV by holding down the power button on your remote for 5+ sec until the TV turns off and on again, deleting and downloading the apps again, and completing full reset of Smart Hub to correct the issue.
Please also make sure your TV is running the latest firmware version. Go to: Settings > Support > Software Update.

Unhappy
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The TV worked for 3 days before the power supply fried. It tripped the surge suppressor I had it plugged into. It also cost me an additional $250 to have Best Buy come out and R&R this TV. They should have back charged Samsung.
