This was unfortunately a regrettable purchase, but I was thankful that I bought it through Amazon because the return process was smooth, as has been my experience with most unsatisfactory products purchased through Amazon. First and foremost, I'm an iOS user of 10 or so years, but have experimented with usage of Android on multiple occasions (once with a Note 9, another time with a Note 20 Ultra, and just recently with the S23 Ultra). I have no issue with admitting that Android triumphs in certain areas where iOS is very lackluster, but also feel the same way in reverse in thinking that iOS wins over Android in many areas as well. I suppose if I had been an Android user all along, these issues would be minute because I would be accustomed to them. So, I will give a few reasons why I have come to the conclusion that the S23U was not for me and why I switched back to iOS (and went with an iPhone 14 Pro Max): - My biggest gripe was the battery life. I chock up many of the positive reviews (both here on Amazon and on other websites containing reviews that I used to influence me to buy the S23U in the first place) to not knowing any better, and potentially being lifelong Android users. Within a couple of minutes of removing the S23U from the charger, battery life began dropping. This is after extensive viewing of YouTube (or Google) tutorials for advice on what settings would best be used to preserve the battery life and make it last longer. Every potential setting that could be altered to make battery life more satisfactory on this phone was applied, but to no avail. I am your average social media doom-scroller and will snap a photo here and there, but never had any intention of heavily using this phone for, say, classroom note taking or anything similar. So, when I took the phone to work for a 4-hour shift and it was down to half its battery life by the time I left, even though I'd hardly touched it other than maybe throwing on a music playlist, it was a pretty big blow. Throughout the time I had this phone I was mortified at the thought of getting into an accident with this thing on hand in the event that the battery died on me, but just didn't really feel like I should I have to prioritize the idea of carrying a spare phone charger around with me at all times. With an iPhone and its already built in settings, I could take it off of the charger, doom-scroll for an hour and would *maybe* lose 1-2% battery life in that time. - Secondly, I had a heck of a time with notifications and particularly, text messages on the S23U. There were multiple instances where I would miss text messages because the phone never once notified me that someone had texted me. Again, I took to Google and found out that an additional app (Glimpse Notifications) can be downloaded to remedy this issue, and it luckily did, or that I am aware of. No one should have to download an app (also using up unnecessary space on their phone) in order to ensure they receive something as simple as text messages and see them on their lock screen. - Your average joe-schmo photos came out incredibly beautiful....that is, so long as using the zoom function was not imperative to whatever you were photographing. Even 3x zoom proved a massive disappointment as whatever you were taking a photo of was incredibly grainy and blurry. I have a friend who is a lifelong Android user (who also told me I would never want to go back to iPhone and would be incredibly satisfied with the S23U) whom I sent sample screenshots to, and he was shocked at how disappointing the photos were. Like I said, if you're just taking the average photo of something close up to you, it's a very pleasing sight, but if you're trying to take picture of an animal around 12 or so feet away and need a little bit of zooming...prepare for disappointment. Facial recognition was testy, to say the least. It didn't recognize my face half the time (even though I reset it, then set it back up again anew), so I just got fed up and decided to do away with it and go with the fingerprint scanner. All in all, I spent the majority of my time owning this phone navigating the settings menus or downloading apps to try and get basic functions to operate correctly. There was little enjoyment from it. For the money that I spent, it just wasn't worth it to me, personally.
