    Day 4 of use. Arrived as described. Bought Excellent condition 512gb unlocked. All true. Nearly indistinguishable from a brand new phone. Minor nearly unnoticeable tiny splotches on the back really can't see unless your looking for it.
    Absolutely flawless screen and brand new battery life.

    --Charging port is a little dirty
    --going from note 10+ (2019) they changed the emojis which i hate deeply but is not the sellers fault. Just something to note the emojis do get uglier if your coming from a older device.

    Only disappointment with this is price. It dropped over $100 maybe even nearly $200 just 2 or 3 days after I purchased it. And even now still sits at over $35 less then what i originally bought it for. I've noticed The price changes all the time up and down and is very inconsistent so if it's just ever so slightly out of your budget check back daily.

    Other than that it is what it says. As described.

    Phone is good. Bezel was quite scratched for something marked as "Used excellent", but in a case you can't really tell anyway. Had to replace the loud speaker as it was crackling and buzzing right out of the box. Luckily, the back glass came right off after just running my nail along the seam, no heating required. Speaker was 20$ here on Amazon. I didn't send it back because I wanted the 512Gb/12Gb Ram model, and it was a good price. Your mileage may vary depending on your expectations and experience.

    5.0 out of 5 stars Bang for buck, you'd be hard pressed to find a better Samsung S-series phone
    Reviewed in the United States on December 19, 2025
    Verified Purchase
    I was hesitant to upgrade my trusty S10 but it was my birthday and I was feeling saucy. For the price and the various reviews I read, this is THE bang for the buck. Compared to a S24, S25 or S26 there isn't much missing and some would argue it's one of the last of the breed especially with the BT S-Pen (the new ones don't have anymore or have lesser features). It STILL has "updates" life left and WILL get One UI 8.5 (any day now actually). This is noticeably faster and better in pretty much every way. I didn't know what real battery life was until now. I can go a full day without a charge; my other phone I was lucky to get 4 hours of my normal use and even then I was on high alert to where the nearest AC plug is. To go from 80% to 50% was scary but that 50% to 20% when the S10 would power down to safe mode was a constant source of anxiety. With this it's like time is on a different measure. I could watch the % tick down on the old one, on here it barely moves. A true game changer. The ONLY "gripe" I have is this beast is a big-boy. It's probably double the weight and dimensions in every way. I can absolutely feel it in my front pocket and if I wear my PJs it will pull the pocket down even. Due to that weight it will also pull the suction cup mount off the windshield of the car more often than not so I had to switch to a cup-holder style that's more secure. It is curious why Samsung didn't let it wireless charge their own Galaxy Watch Ultra (when I try the watch says it's "not compatible" when I thought it is just Qi charging?) That's a real shame; not huge as the watch lasts a couple days as it is, but would have been a nice-to-have given it's all their same flagship stuff from the same time-frame even... I thought I'd miss not having an SD slot (and kind of do in a way) but I went from 256GB to 512GB internal now. Similarly I used to have the ol' Bixby button on the S10 commandeered to launch Home Assistant. I thought I'd miss that, but literally last night I discovered that the "RegiStar" plugin to Samsung's "Good Lock" (yeah dumb name) has the ability to assign all kinds of things to all kinds of other things. So now my main power button long-press launches Home Assistant. BOOM!

    Overall "no ragrets" and almost wish I'd done it sooner.

    5.0 out of 5 stars Galaxy S23 Ultra Renovado: Potencia de flagship, precio inteligente y estado excepcional.
    Reviewed in Mexico on December 23, 2025
    Verified Purchase
    Contexto y Experiencia Previa:
    Como comprador habitual de tecnología renovada (vengo de un iPhone 15 Pro Max Renewed), adquirí este S23 Ultra para actualizar a mi esposa. Buscaba el equilibrio perfecto entre rendimiento flagship y valor, con la seguridad de la Garantía Amazon Renewed de 90 días.

    Evaluación Objetiva: Un equipo que supera expectativas.

    1. Rendimiento y Funcionalidad (Impecable): ★★★★★
    · Potencia Pura: El Snapdragon 8 Gen 2 es un monstruo. Cero tropiezos, calentamiento o reinicios inesperados. Multitarea, juegos exigentes y productividad fluyen sin esfuerzo.
    · Sistema de Cámaras Profesional: Probé todos los lentes (0.6x, 1x, 3x, 10x) y modos de video. El zoom, la estabilización y el enfoque son excepcionales. La cámara es una herramienta de creación, no solo un sensor.
    · Conectividad Total en México: Completa compatibilidad con redes nacionales. 5G funciona perfectamente con Telcel y es compatible con ALTAN Redes. WiFi 6, Bluetooth, GPS: todo verificado y funcionando al 100%.
    · SPen y Software: El lápiz es preciso, la pantalla Dynamic AMOLED es espectacular y el software es fluido. Todas las funciones probadas operan perfectamente.
    2. Estado Físico y Componentes ("Excelente" que cumple): ★★★★★
    · Condición Física: Llegó en un estado que puedo describir como cuasi-nuevo. Tras una inspección minuciosa, solo se aprecian leves signos de uso compatibles con "renovado" (micro-marcas en el marco visibles solo bajo luz específica). No hay rayones en pantalla, golpes, abolladuras ni desgaste evidente. Supera ampliamente la expectativa para la categoría.
    · Batería (Dato Clave): La salud de la batería reporta un valor nominal excelente (cercano al 100% según diagnóstico del sistema). Este no es un equipo con batería desgastada; la autonomía es la esperada para un flagship nuevo. Carga rápida e inalámbrica funcionan perfectamente.

    Análisis para la Comunidad: Por qué esto merece 5 estrellas.

    La confusión nace de no separar las categorías. No se debe juzgar un "Renovado - Excelente" con la vara de lo "Nuevo Sellado". La pregunta correcta es: ¿Este producto cumple de manera sobresaliente y honesta con lo prometido para su categoría de reacondicionado?

    En este caso, el S23 Ultra no solo cumple, supera la expectativa de "Excelente". Su funcionalidad es perfecta, su estado estético es muy cercano al nuevo y su batería está en estado nominal. Redondear hacia abajo por no venir en una caja de retail original sería un error que desincentiva la oferta de productos renovados de alta calidad.

    A los compradores: Si reciben un equipo que sí cumple como este, déjenlo claro con su calificación. Si reciben uno que no cumple, usen la garantía de 90 días sin dudar. Ese es el sistema funcionando. Las reseñas deben reflejar el resultado final, no solo la frustración inicial.

    Conclusión y Recomendación:

    Veredicto: 5/5 Estrellas. Una compra excepcional.

    · Ideal para: El usuario inteligente que prioriza el rendimiento, la funcionalidad y el valor por encima del empaque original. Para quienes ven en el teléfono una herramienta de trabajo y creación de primer nivel. Personas que, respaldadas por la garantía, toman una decisión financiera y ambientalmente sensata.
    · No ideal para: Coleccionistas o quienes buscan únicamente la experiencia de desembalar un producto virgen. Para ellos, la opción es pagar el precio completo por uno nuevo.

    Sugerencia a Amazon:
    Un sistema de gradación más transparente (ej: fotos reales del equipo, rangos de batería específicos para cada categoría) incrementaría la confianza y reduciría la fricción en el proceso de compra de renovados.

    En resumen: Este S23 Ultra renovado es la prueba de que se puede acceder a la tecnología de punta, en estado extraordinario, de manera responsable y económica. Mi esposa está encantada con el salto desde su S21+. Una compra altamente satisfactoria y recomendada.

    The phone I received was in flawless condition and everything worked as expected. The only minor niggle is 'Factory unlocked' to me means Samsung firmware (no carrier bloatware). Mine came as Verizon but was easily flashed back to Samsung native firmware (XAA) with a modified Odin flash tool. Overall, very happy with the purchase

    1.0 out of 5 stars Not Factory Unlocked – Locked to AT&T, Bricked After Seller Error, No Resolution
    Reviewed in the United States on June 22, 2025
    Verified Purchase
    I purchased this Galaxy S23 Ultra from Big Box LLC on June 17, 2025, based on the listing clearly stating the device was “Factory Unlocked.” That turned out to be false.

    📅 Timeline of What Happened:
    June 17 – Order placed and shipped same day.

    June 18 – Inserted SIM and discovered the phone was locked to AT&T.

    June 19–20 – AT&T confirmed the device was under an unpaid installment plan and ineligible for unlocking.

    The seller provided an incorrect unlock code, which they later admitted was missing a digit.

    After multiple failed attempts, the device became MCK locked — a high-level lock that makes the phone completely unusable.

    I spent over a week trying to get a valid unlock or MCK code from the seller. They kept stalling.

    June 28 – Seller admitted they couldn’t obtain the MCK code and instructed me to return the phone.

    ⚠️ Why This Matters:
    A factory unlocked phone should never require an unlock code — and certainly not end up MCK locked.

    I made 8 trips between T-Mobile and AT&T trying to resolve this.

    I lost 15+ hours of professional time, and the phone was bricked because of the seller’s incorrect information.

    After all of this, the only resolution was to return the phone — which I did under protest, with the entire incident documented.

    I’m grateful that Amazon support has been helpful and professional, but buyers should be extremely cautious with this seller. A device tied to a financing plan should never be sold as “factory unlocked.”

    If your time and peace of mind are valuable, look elsewhere.
