    Son had this as his birthday present, he loves using it and has been using this for over 3 years now. It is still going strong, and no malfunction to it. The battery life is still good, even after many years, and it is compatible with our phone carrier, even when we brought it overseas. We were able to use it anywhere in the world. Very nice.

    I came to this phone from a OnePlus 6t after growing suspicious of OnePlus's company decisions/priorities and wanting a smaller phone, and I have been largely satisfied with it over the past 3 months. Since the last Samsung phone I had (S7), the software experience has gotten much better. GoodLock lets you customize basically everything OxygenOS did (taking away OnePlus's main argument nowadays).

    The speakers and vibration motor are much higher quality than I was used to, and the overall construction of the phone is very solid. I haven't had any durability issues with it in the past 3 months, and the phone still looks pristine even without a case. The cameras are also fantastic. I have been using my DSLR far less than I was before because of the wide range of capabilities the three different focal lengths have. I only wish the wide angle camera had a macro mode like some other phones do.

    My only worry with it has been battery life. The OnePlus 6t really spoiled me in this regard, getting 7-8 hours of screen on time even after 2.5 years of use, and initially this phone didn't live up to that. However, over time it has gotten better (as people said it would), and it's probably around that range now.

    Overall, I would definitely recommend this to anyone who is looking for a small phone with top end features.

    I got it pre-owned and it was in a pretty good condition with barely any defects or scratches. The performance is fantastic and it's very snappy with no lagging whatsoever. The camera is top top, selfie shots are just amazing and rear shots are no different!

    Only thing I wasn't impressed with is the battery. I don't know if it's because of the usage patterns of the previous owner. It's manageable for me though because I always have access to power and I don't mind plugging in every now and then.

    Overall I'm enjoying it and I think I got a bang for my buck!

    I bought this phone after having the s9 for a few years. I really did not want to upgrade, but I was having issues with it draining super fast, even in Safe mode. My over all impression with this is phone is amazing. After having it for a month. The only thing I dislike is the under screen fingerprint reader. It does NOT* work well, if it all, *with* weird off-brand screen protectors. It works about 30% of the time with the one I have on. It's worth getting good quality screen protectors from otterbox or another company that is really reputable. Now with that being said the face recognition is fast, you'll want a light color background for when it's dark where your using it. The thickness is honeselt not, it's slim, even while packing a 4,000mah battery.

    I upgraded from an S7 Edge to this S21. The phone size is exactly the same as my old S7. The battery life on this new phone is awesome. i can go all day without recharging. Like all phones, if you are using Maps, the charge time is reduced quite a bit as that app sucks a lot of juice. So far, after a month, I like this phone quite a bit. I bought it on Prime day and got a real good price. The normal retail price is otherwise a bit much for what it is. I am totally satisfied though as 5G is lightning fast. My old S7 took a lot of time to refresh simple things like the weather app. This S21 does that instantly. It is a high quality phone.

    I love all Samsung products, I've owned many and have been pleased with every purchase. My latest purchase the Galaxy S21, the screen, the operating system, the hardware is sweet perfection. I love the size, the display is amazing, it's a beautiful phone and the quality is over the top. I'm very pleased, as I've been with every Samsung product I've ever bought. I'll never buy any other phone than a Samsung Galaxy. Buttery smooth and rock solid. I've had many Android phones, including pixels, Samsung Galaxy's are far superior. The battery lasts 2 full days , the last pixels I bought got about 6 hours. No comparison.

    Similar to my other Samsung Galaxy phone I have owned. Great pictures, battery life is OK, sometimes doesn't last a full day. I have a screen protector on it since I received it and also had it in a case with a built in cover to double protect it. Trouble using the finger ID with the double screens. You must also press pretty hard for it to recognize your fingerprint. I really like the phone buy for battery use I wish I would have stuck with my Nord N10 5G.

    Es un dispositivo muy bueno en cuanto a rendimiento y estéticamente es muy bonito. Hasta ahora todo funciona a la perfección, solo que los datos de la descripción son incorrectos: el chip es el Snapdragon y no el Exynos (aunque dicen que el Snapdragon es mejor), y son 8 GB de RAM, no 12 como dice el título. Igualmente hay que tener en consideración que hay que comprar un adaptador de corriente por aparte, pues no lo trae incluido. El paquete llegó en perfectas condiciones, aunque con un día de retraso.

    Actualice mi samsung s8 por este modelo y la diferencia es masiva, seria el celular perfecto si todavia tuviera expansion con micro sd y jack de auriculares, pero al menos la menoria de 128gb es suficiente y los audifonos bluetooth han mejorado mucho, por lo que no extranio tanto estos faltantes.

    La version que tengo cuenta con el Snapdragon 888 que es un gran plus ya que la version Exynos es inferior.
