Samsung Galaxy A51 A515F 128GB DUOS GSM Unlocked Phone w/Quad Camera 48 MP + 12 MP + 5 MP + 5 MP (International Variant/US Compatible LTE) - Prism Crush Black

I purchased the 128GB with 4GB ram model in all black. My wife's S8+ that was close to becoming non-functional and I needed a new phone asap. I had previously purchased an A20s for my son and so I first ordered the A30s until I did some research regarding my mobile provider T-Mobile in the US. I cancelled the A30s and got the A51 primarily because of the supported LTE bands. T-Mobile uses the following bands 2, 4, 5, 12, 66, 71 The A30s only supports band 5 from the that list! However, the A51 supports band 2, 4, 5, 12 and 66. I was gladly willing to pay a little more to ensure I had maximum connectivity with my carrier so I cancelled the A30s and purchased the A51 instead. Now with that primary consideration out of the way, on to the rest of the review. I'll start with the best parts first. 1. Call quality, reception and connectivity The call quality is excellent on this phone, right up there with my s10+. I think the microphone quality has been improved because my wife loves using the speakerphone and on her hold s8+, her voice occasionally cut out here and there as the mic tried to pick up her voice. Also, the sound quality of the voice has improved as well which further helps to understand the conversation. Reception has been about the same compared to my s10+, which is to say pretty good. We measured on signel strength and asu. The mobile data speeds are excellent even in areas that are typically weaker in signal strength. 2. Screen Samsung AMOLEDs are the best in the business when it comes to screen quality. We are a little relieved the screen is not curved because this allows us to get a robust case to protect everything. The colors, quality and resolution are all indistuingishable compared to my s10+. The front camera is a tiny pinhole so the entire body is pretty much all screen. There is an in-screen fingerprint reader which is optical, rather than infrasonic on my s10+ but it is still reasonably fast to unlock the phone. Yes it is slightly slower than my s10+ but we're talking milliseconds of difference. 3. General usability My wife is not a gamer so I can't say anything about the gaming experience but she does use a ton of media and productivity apps. For all of her use on them so far, she says they feel snappy. They all open fast and transition well and she multitasks as much as before without a shred of difference. When we first setup the phone, we were concerned because there was some UI lag but realized a lot of processing was being used during the Samsung Switch, which transfered her entire old phone to the new phone. Once the switch was done, we rebooted and the phone was responsive and fast. 4. Camera The camera hardware has some beefy specs. But for a mostly point-and-shooter, it's hard to really go wrong many camera setups. Picture quality looks great in the light and not as good in the dark compared to my s10+. The slower camera speed is noticeable, transitioning between the main camera/wide/macro takes about a half second, where on my s10+ is pretty much instant. The shutter is just as fast, luckily. If camera speeds are important to you, you would probably not be happy with this phone. 5. Battery I have to admit, we were looking forward to getting more usable time out of the battery. The battery is 4000mah unit and the s8+ was only 3500mah. However, through the typical daily use, we found that the end-of-day percentage left were about the same. We average about 4 hours of on-screen time scattered throughout the day with app use and web-browsing and the battery was around 40% left, which is the same as the s8+. If long battery life is important to you, you would not be happy with this phone but keep in mind, it can easily last an entire busy day on a single charge. Overall, we like the phone for the price of under $300.

Since this is a dual sim phone it was made primarily for international use. Although it was made for international use it works fine in the states. The big benefit is that this phone has been available in Europe for quite awhile, thus a good price drop of the mature international Samsung A51. Standard is 4 GB of memory and 128 GB of storage (not to many phones come with that amount of storage). The Samsung A51, American only model, has recently come out in the states and is considerably more expensive than the mature international version dual sim phone. Another fringe benefit, you can put two sim cards in the phone (only one is active at a time) but that allows you to have two different phone numbers for a single phone. The only surprise was turning it on for the first time. Everything was in Spanish. All of the initial setup was in Spanish. So, I backtracked displays a bit until I found an early display that allowed me to change the phone over to US "English" language. From that point on it was smooth sailing. Without a doubt, this was the easiest phone to set up I have ever owned. There is a Samsung App called Smart Switch (available from Google Play) that you put on your old phone that talks to a comparable Smart Switch on the Samsung A51. It basically transfers Apps, Files, Contacts, Calendars, Etc. from the old phone to the new one. In not sure if it is using NFC or Bluetooth, but it work great in transferring everything. It tells you what it could and couldn't transfer. The Quick-Start Guide is a little thin, I would highly recommend getting the PDF Users Manual from the Samsung Home Page! The manual is 197 pages, it unlocks the myriad of features on the phone. There is a Virtual Assistant "Bixby" included. Bixby seems to be much smarter than "Alexa" or "Siri". A nice surprise was the compatibility of the phone with my cars Bluetooth phone system. It paired effortlessly with the car and it also downloaded the entire contact list from the phone into the car system. I haven't had the phone long but thus far I have had a lot of "great" surprises. This was a great value getting the price break due to it being a mature international version of the Samsung A51. I will follow up after I use the device for a while to update my initial assessment of the international version of the Samsung A51 Smart Phone. There is a clear plastic display protector pre installed, there was nothing in the package that mentioned that.

Nice phone for the price. But doesn't work with a few network providers like sprint and Verizon but it works with T-mobile and some other providers. Fingerprint scanner can be annoying sometimes if you decide to leave the protective film glass on the screen or if you use a screen protector. Phone not water proof but can survive if it falls into water. I'm satisfied with this product including it packaging but if u are using sprint or Verizon get ready to switch carriers or just don't get this phone. If you are ok with switching carriers then pleas go ahead and purchase this phone. I promise you, you will love it.

All those people complaining about the phone not having 6 gigabytes of ram did not look close at the description before buying make sure you know what you are getting. That being said, I have had this phone for 10 days and it has been great, only a few times have I had issues with the device lagging while scrolling on web pages or opening apps but I have not has anything else like that happen to me since those first 2 times, which I think is pretty acceptable considering the price. The camera(s) are fantastic, I have taken some photos of my birds with this and if you zoom in really far you can see their small individual feathers, which is a big upgrade from my old Motorola E4 smartphone I've had before this phone, the only downside is using the Google Street view app to take 360 photos because I guess the gyroscope is not top of the line, and there can be strange stitching results or large black parts in the photo once its processed even if you got all the photos in the augmented reality view in the first place, however I don't believe the blame all goes to Samsung as there's probably something wrong with the coding the developers wrote for the application. You can play games like Assassins Creed Identity, and Call of Duty which is great as well, and do basic video editing such as trimming, adding, and cropping. As of now however I have not experimented with how well the phone performs if you have a game capture application running as that's not a major concern for me. (As a side note to anyone who may be concerned with preinstalled malware or spyware as seen in some cheap phones, I have done many full system scans with the malwarebytes application for android in safe mode and have found nothing, so if you are coming from say a BLU Products phone which are well known to have Trojans and malware than you shouldn't be worried about anything like this for this phone.) So to sum it all up, great mid-range phone with amazing camera(s), and you cant go wrong for the price, I defiantly recommend considering this phone.

After learning about the A51 differences I would like to say that model SM-A515F/DS has 128GB internal storage, 4GB of RAM and doesn't have NFC setting. Model SM-A515F/DSN has 128GB internal storage, 6GB of RAM and has the NFC setting. I purchased the Samsung Galaxy A51 Prism Crush Black phone April 27, 2020 and two days later the phone was at my doorstep (just the phone). The box came in completely sealed and it had all the accessories. After going through all the configuration (I did not setup fingerprint or face recognition at the beginning) I was in business. The colors on the Samsung Galaxy A51 are amazing. I did make a change under Settings > Display > Screen Mode, from Natural to Vivid and turn on Dark Mode. The fingerprint is under Settings > Biometrics and Security > Fingerprints. It took me a while to be able to setup fingerprint. Honestly did it like 30 times until it read 100%. You will have to move the finger to different angles until it reads your fingerprint completely. Every time it reads new lines the percentage goes higher. Once I was done, I tested it and it worked fine. I used all other 9 fingers different angles to see if it would let me login, and it DID NOT. The phone does take great pictures. I tested the macro on one of my dogs nose and WOW, the pic was stunning. The pic of a lizard was taken in macro. Calls are clear and it shows LTE with strong signal. I am registered with MetroPCS and my dad with AT&T. I used my dad's AT&T sim card and it worked (picture shows Metro by T-Mobile, AT&T). The phone does have 4GB of RAM. When I purchased mine the price had drop to the point I couldn't pass it. I didn't see anything on Amazon page at that time, but I don't care, I'm very happy with the phone. Aside from the A51, I purchased a Feitenn Samsung Galaxy A51 Metal Case (ASIN B0839C38GM). The case is sturdy and it DOES protect the phone. The screen protector IS NOT attached (together) to the metal case like it shows on the pictures, and the screen protector IS NOT gorilla glass, it is just regular and it doesn't have the whole for the front camera. I placed an order for 3 Tempered Glass (ASIN B082S7NCB8). Thanks

Thought it was a good deal so bought two of these. One stopped charging after 6 months. Took it to uBreakiFix, samsung's official repair store, they wouldn't touch it even for money. Sent to samsung, they recognized it was under warranty but said they had to charge $400 to fix it so I had them send it back unfixed. I ordered the part on ebay for $30 and fixed it myself but it never worked quite the same. I think samsung sabotaged it. Used it on T-mobile and while it works its missing some LTE bands and depending on where you are you get dropped calls and low speeds. 3G worked fine. In the end I regret not paying the extra $100 for the US version, would have saved so much time and money. Had to buy a different phone to replace it. UPDATE: The second phone has now stopped charging. I will repair it like I did the first one but I'm only doing it to get some local files off then buying a pixel. End result was a phone that didn't work that great and neither one made it past 16 months. These were lemons. DON'T BUY in USA.

I am very impressed with the phone so far. The display has a nice resolution and refresh rate for smooth, crystal clear operation (for a non flagship phone). Plenty of storage space, plus an SD card slot for expansion. The camera resolution seems great so far, but i have not used it extensively yet. I use Cricket Wireless, and the switch was as simple as moving my SIM card over from my old phone and allowing time for contacts and messages to transfer over. The phone works well with Cricket. It is nice that this phone does still have a 3.5mm headphone jack, something becoming more rare. Speaker quality is nothing spectacular, but not bad. The only feature I wish this phone had was a removable back panel and battery, but I fear those days are behind us. I also wish the cable for the charger was a little longer, but that is jusr personal preference. Because I have read conflicting reviews, I will mention that my phone did arrive in a labeled, sealed box from the factory with all accessories. I will update with pictures later. A pair of wired earbuds was included in the box, but they are hard plastic and are very uncomfortable in my ears. The worsr part about my experience by far was the shipping time. I get that Prime shipping to Alaska is not going to be 2 day shipping, but to me it is unacceptable for a seller to wait 4 days after the purchase before attemtping to ship the product. Then my shipment was delayed anothee day immediately after shipping with no explanation. Everything after that point was in the hands of USPS, being "out for delivery" 3 days in a row. I live near the end of the route, and the carrier delivered mail only and left the parcels on the truck because it was almost 8pm.

I bought this phone for a relative outside the United States and it's very good, excellent quality, the battery lasts all day, and it's quite fast, I would buy it again.

I mainly use this phone for text, calling, taking pictures, browsing social media, as an alarm, playing gacha. So far it's a great phone. The camera is really good and takes nice pictures. I've never had a problem with the thumb print unlock. At it's worse i've had to do it twice because of bad thumb placement the first time. It 95 percent of the time unlocks first time with thumb print. It's got a decent amount of storage and also SD card slot. The screen looks very nice and looking at images looks very nice on the screen. The battery lasts me 2-3 days per charge, but with only light use. When I first got the phone, the hey google assistant was always on. This caused the battery to drain drastically over night. If you plug your phone in at night, you might not notice this. This was solved easily by going into settings and battery usage. There are probably some features to this phone, I am not using. But for the price I am really happy with it. My last phone was garbage compared to this. This is a solid mid range phone. It's not a flagship device, but for what you pay it's a great phone.

I have gifted it to a family member and I’m so gspppy they liked it so much
