Samsung Galaxy A51 with 128GB Memory Cell Phone (Unlocked)
I broke my Galaxy S10+ and I wanted to go crazy. Prices skyrocketed for some reason and I had to go through insurance which took a while. I went and purchased this phone and I do not regret it at all. Honestly, with phones like this, there may never be a need to buy flagships again. It does only have 4gb RAM and it can be noticeable especially with the apps I pack and "multitasking" I do being a full-time student with a small business. I was able to get a replacement for my original phone, but if I hadn't I wouldn't have been mad. This phone is beautiful on the outside, and impressive on the inside. An almost comparable battery to the S10+, a decent sized screen, with the upgraded cameras, at the incredible price?! Tired of ridiculously priced phones? Want something affordable without feeling embarrassed? Buy this phone.
If you are looking for a flagship quality phone for around $500 less
this is your phone. I would warn that it is thin, slippery, and somewhat fragile, so don't go crazy with it until you have a good quality case and a tempered glass screen protector installed.
speakers are so-so but does sound great with headphones. so far as i can tell the only things a flagship phone will do that this won't is to wireless charge, or drop in 5 feet of water. if you can live with that, save your money and get this phone.
I bought this phone for my mom last week when her old Motorola suddenly stopped working. She did not need too many functions but likes to take pictures so I picked this phone. I was a bit hesitant to begin with since there's only 1 five-star review at the time but I'm glad I decided to take the risk. The phone is very slim, classy in appearance, and easy to setup and use. Also, the current sale price accompanied by 128GB is phenomenal. Overall, my mom loves her new phone.
My only complaint is the dimension of the phone is longer than my current S7 and I worry it might drop out of my pocket since I have a habit of using it as a wallet instead of carrying a purse. It's a tough decision.
Great midrange phone from Samsung. Looks and feels premium. Has all the essential features without the unnecessary gimmicks of flagship models. Love the plastic chassis, as glass adds fragility and weight with no real benefit and I'm using a case anyways. Headphone jack is a win. OneUI looks great. Updates have been plentiful. I switched from an iPhone 11 and using the Galaxy A51 is way more fun. You can't go wrong with this phone.
I had a time looking for a new phone for my boyfriend. Nick the salesman helped me out to get exactly what i was looking for.
My boyfriend absolutely loves this phone. Its easy for him to use as he has arthritis and the fingers dont move easy.
When I went into the Bestbuy store I was not sure which cell phone to purchase as an upgrade from the prior cell I bought at Bestbuy a few years ago. The sales clerk was very helpful, I made the decision based on his knowledge of the phones and what I actually required from my phone. I am always happy with the service and attention when shopping Bestbuy!
Upgrade from a Samsung I bought 2 years ago. Lots of memory on this one without being too outrageously expensive. Not happy with the voice recognition, but I'm hoping that gets better with use. Not optimistic, though. Otherwise, it was an easy transition from my prior Samsung, which is why I stuck with this brand. Camera is GREAT, especially compared to my last one. Captures colors well without washing them out. Turning flash on and off is easier. So far, I'm satisfied overall.

Samsung's Galaxy A51 packs a great screen, a handful of cameras, and a big battery -- what more could you ask from a mid-range smartphone? Well, more consistent performance, for one. Despite using a reasonably powerful chipset, the A51 is oftenFull Review

Samsung Galaxy A51 review
The Samsung Galaxy A51 is a good midrange phone in an era of good ones, and doesn't quite match up to the iPhone SE and Pixel 3a.Full Review
A:AnswerYes, this will work on Straight Talk. If you have the AT&T or T-Mobile SIM it should be simply plug and play. Technically it should also work on the Straight Talk Verizon SIM's as well, but some people have noted issues getting it to work properly with the Verizon network while others have had no issues, so YMMV.
