Sony F5121 reviews

Xperia X F5121 32GB Smartphone (Unlocked, Graphite Black) is rated 4.5 out of 5 by 84.
Rated 4 out of 5 by from Great Phone I had to get a replacement after my last met its demise. I had the Z3 before this so there were quite a few changes. I love the size; i have small hands but this fit quite well. The issue I had before was the camera button on the side, it was slow before but now there is no lag when taking a photo. The resolution is clear, great videos and photos even the front camera has excellent quality. The power saving features are good. I was running really low on battery one day and it would adjust the system to battery saving mode. The only downside is the small apps that they removed even before the Xperia X. I really liked the screenshot feature from before where I get to edit before I saved. Overall great phone.

Rated 4 out of 5 by from Awesome phone! I love this phone for the most part. It's an awesome device, performance is great, no lags or stutters, the battery has gets me through a full day with no problem, and I love the new aluminum-back design. I just wish Sony had not disabled the fingerprint scanner in the power button for the US market. That really makes no sense, the scanner is still in there, they just chose to disable it on all American the units. It can be enabled, but the procedure is not for the tech challenged. It should not have been disabled in the first place, so for that I knocked off a star.

Rated 5 out of 5 by from Awesome phone overall, wish it had better battery. Things I like in this phone: Speed of operations. Cameras, both are amazing. The sim/memory chip slot, smoothness. The case is sleek and looks better in person then in the pictures. Sound quality of calls and music is amazing (probably the best). The screen quality is best and glass doesn't get fingerprints as easily as other phones. Things I don't like:(most are not a big deal or deal breakers) The power button has finger print reader but doesn't work on American phones. Battery life is short in performance mode. The button placements are in a way its hard to put the phone on a car mount.

Rated 5 out of 5 by from Great phone This is a great phone. It has an awesome screen with lots of brightness and color, it is very quick and doesnt lag, has good battery life, great camera, loud speakers, looks hella fresh, and makes/recieves call very clearly. I think i like android 6.0 better than 7.0 because I dont like the google contacts or google dialer app, but I understand they work together since they are both google products. just wish there was more functionality. I also dont like the fact there is no call log widget or the LED notification placement. Other than that Im happy. good buy overall.

Rated 4 out of 5 by from Solid Phone At A Great Price I own the Xperia X Performance and purchased the Xperia X for three of my children. They are all solid phones and there is no noticeable difference in performance between the two models. Same displays, same cameras. Only minor battery difference and upgraded chip in my Performance version. All screens are sensitive to smudges but that's the only con. I'm not brand loyal and research extensively prior to each purchase. This is our third batch of Sony phones and by far the best built to date.

Rated 5 out of 5 by from A very nice smartphone As SONY can do, this smartphone is a very cheap middle class smartphone, but elegant, and include all the main characteristics (3/32 Go, 5 Full HD screen 2,5D class, uSD memory card reader up to 200Go, hexacore processor, ...) and same functions (GPS/Glonass/Beidou, accelerometer, NFC, 23Mpx,...) than the top versions. Delivered with Android 6.0.1, but can be automatically updated to the last 7.1.1 version as soon as it will be connected on Internet. Fingerprint sensor is inactivate on this US version due to licenses issues, but very easy to find how to recovered it. This smartphone is compatible with the major mobile phone networks in Europe (included 4G/LTE), important for all the travellers... Very happy !

Rated 5 out of 5 by from excellent phone and dealer Turned phone on and connected to wifi and it started updating. Took a while but updated to android 7.1.1. Plugged in sim card, (using consumercellular) phone was recognized and software downloaded and was ready to go. Last phone was Moto G3; no comparison much higher quality and good size to carry in pocket.
