I'll break this down into a review of CEX first then the phone below;

Buying the phone was easy (as it always is when you are offering money lol) however CEX did cancel my order twice but I believe that was due to my poor mobile data connection.

Once my order did go through it arrived quickly and safely, included was a usb c cable for charging. No complaints to CEX they were quick and I got exactly what I ordered

As for the phone, what an upgrade!!! I finally had enough of my s10+'s awful battery life and sluggish preformance. Everything is better however I do miss the headphones jack and sd card slot, although the latter isn't so important with the 512gb of storage, my previous phone only had 128gb. The screen is really crisp, although has a few scratches but thats on me for buying a C grade. No other noticable damage on the phone or S pen. The battery is really good, I don't even have to think about charging it during the day so long as I charged it last night, I'd guess it could last me two days if I was careful but it charges quickly so no problem if I need to juice up in a hurry. The camera is a big improvement with up to 100x digital zoom, although I've found anything past about 17x is pointless as it becomes blurry but not unusable. The S pen is a fun little addition but doesn't have much use, I mostly use it for the ocasinal doodle, not that I'm much of an artist. The preinstalled drawing app "pen up" is very very good, my artist friend tried it out and was impressed, it has all the features found in paid drawing software and is easy to use. The speakers are clear and loud, you even get decent bass which surprised me, but I guess everything has come a long way in five years. Small thing but I noticed the touch ID is much quicker which is very nice. Not too sure if the flash gets much brighter than my s10+ but it's perfectly good as is. A few negitives to point out, no bixby key (which I had remapped to open the files app) which kinda sucks, also the volume buttons are on the right above the power button, I find this harder to take a screenshot which I now have to do with two hands unless I'm holding my phone with my left hand which I don't often do. The benifit to having all the buttons on one side is that you can rest it against a wall easier and if it gets pushed into the wall you won't push any buttons by mistake. Lastly not an issue for me but it's quite a heavy phone

Overall I'm pleased with it and would recommend to someone with an older samsung phone looking to upgrade

I am a woman with small hands and fingers. Yet, no matter how I have taken advantage of keyboard layouts or made adjustments, I get so many mistakes and have to do corrections literally for every few words that I type on the screen. The amount of stray characters and additional letters being inserted, even when I use the space bar between words. And what makes it worse is the terrible suggestions predictive text makes, or the mistakes it inserts! I used to be able to type on any of my BlackBerry keyboards throughout the years so fast with two or more fingers, without virtually ever needing to look at the screen or keyboard, and was able to produce text, long mails and even draft very long documents mistake free 99.9% of the time. The amount of mistakes that come up on my S23 Ultra keyboard is always voluminous and it is frustrating and a time vampire to keep having to reread every 3 or 4 words to make corrections, and then having to reread what I type over and over to ensure the corrections are mistake free. probably made in excess of 100 corrections while typing this.

I frigging hate this phone and get so frustrated, but the few phones with real keyboards on the market now are garbage.

Plus I failed to mention I get terrible shooting pains and pins and needles in my fingers, hands and shoulders throughout the day, on a daily basis from having to touch this screen to write messages, or use the net.

This phone would be awesome with a real keyboard. I really am so disgusted with this phone, but there isn't anything much different out there to resolve these daily anxiety producing issues.

I absolutely hate this phone. I actually was very happy with my Samsung Active 8, asnd I love to keep things until I absolutely have to make a change. At the time, Att was promoting the new Samsung 23, at no cost and I when to get that one, but I was talked into the Samsung Ultra by the very talented ATT person because my job requires me to take many many photos. I was told the storage capacity of the Samsung Ultra was a TB. About 3 weeks after I up graded, the phone began to it act up. When I was trying to take a picture the screen would suddenly shift right before I would tap the button. Other things were happening, but I was just thinking it was a new phone and I needed to just get use to it.
The phone is to large for my hands and it very very slick. It is a sleek phone gold trim and lavender body, but slips easily causing me to be nervous that I would drop the phone. I have purchased 4 cases with extra protection.
I did not realize that the screen going over the edge of the side of the phone was such a terrible feature. This makes holding the phone and using it very difficult because your fingers will touch the side a little too much and it interferes with texting or what ever I am doing.
The screen is very easily broken which is something I have never experience before with my cell phones. I had it in an otter box case with cover so the phone was enclosed in an otter box. The phone slipped from my hand slid down my leg and fell about 2 1/2 feet and landed on the parking lot asphalt right by my foot. So, being in an otter box, sliding down my leg and landing right by foot, I did not expect the screen to pebbled and shattered with little spider line cracks that rippled out.
I have been to Att 5 times related to the phone. I have been told that well, it's out of warranty, live with it, maybe Samsung would replace the phone but i may have to pay it off, and more.
As of Sept. 12, 2024 I cannot send nor receive text messages which is a big part of my daily work. Another visit to the local Att store and 3 1/2 hours later I left and still could not send or received text, advance support could not fix it, the supervisor of advance support could not figure it out. I let them know that I had sent our a large number of text the day before and they said that shouldn't be a problem since I have unlimited talk and text. It is Sept. 26, 2024 and I still cannot receive or send texts.
So I have a very expensive phone that has been nothing but a huge pain that I hate. It has a cracked screen because the design is such that it is susceptible to damage, that I pay for a plan with unlimited talk/text that I can not use that feature with my contacts. Oh, I can receive text from Att, and other companies, but not anyone on my contacts list. That shifts when I have lined up my picture causing blurred or repositioning. If there is any noise aside from my phone playing a video, or audio file, forget it.. I feel like a fool, I have tried but I don't know how to get this corrected. Did I say that I really hate this phone?

Product Quality:flagship
Best Feature:all around( s-pen, DeX, zoom camera, vaporchamber for gaming, personalization UI) though expect samsung camera software enhancing photos after shoot
Performance:i set battery at max protection, it lasts 1day

My order arrived after a week from order. I trusted the reviews here to check if they are legitimate store since the phone is much cheaper than authorized store in the mall. This is an expensive purchase after all. The box was delivered exactly as the seller packed it, thanks for their security tape around the box.
There's a lot of freebies which is great! All you need for a new phone:
phone case (clear and thin only),
tempered glass (1 pc. Mine was scratched after 1 week by a knife after a cooking mishap 😵),
charger (ITFIT is already all-in-one! it can wirelessly charge a phone, watch and buds plus it is a nightstand with digital clock, and has 30W charging block which you can you use for the phone),
Gobuymall free retractable cable - lightning, USB-C and old micro

I've added the phone in my Samsung account and it is indeed a legitimate and brand new one, but since it is purchased from different country, their 1-year warranty is not available. The box was resealed (opened to setup PIN) using their security sticker but the bottom is intact, same as store bought. Mine has a Spanish sticker so I think it might have been sourced in Spain or South American countries. They locked the phone with a pin so you have to chat them once it has been delivered, there's a slight delay due to their system said the seller.
I've been using it a week and I did not encounter any problems so far.

Thank you GoBuymall!🥳
