Pros: As others have mentioned, amazing screen... incredibly bright (Sony's default auto-dimming dulls it a bit much for my comfort IMO), and amazing color reproduction. Yes, as many external reviews have pointed out, viewing angles are not amazing, but then again, I tend to not expect 180-degree viewing angles on an LCD display... UNLOCKED HSPA+ and LTE are amazing to have... I unpacked this phone and put my T-mobile USA SIM card expecting to top out at HSPA+... to my surprise, I had a solid 2-3 bars of LTE signal right off the bat (I am in the NYC metro area, where LTE is supposed to be rather spotty, in a pre-launch stage on T-mobile's network). Commuting around the city on a regular basis, seems LTE is up and running quite solidly, and functions amazingly well on this phone. DC-HSPA+ also works quite well, pulling in connection speeds of close to and sometimes exceeding 8-15 Mbps down and 2-3 Mbps up with < 80 ms latency (LTE latency is solidly below 50 ms with around 20 Mbps down and about 10 Mbps up in most places I get it.) Sony's Android skin is rather mild, and quite to my liking. There's very little bloat to mention (I actually like the Walkman app for music playback). Most pre-installed apps have at least some utility (Really got a kick out of the included IR blaster app to control my TV and home theater audio system.) As to speed, the quad-core + 2 GB RAM and fairly bloat-free ROM mean a vastly lag-free experience. For those who really do want to rid themselves of Sony's ROM, Sony has always had excellent dev support (including git access to sources published in a fairly timely manner), and I believe there are already a few CyanogenMod ROM's cooked up for the Z and ZL, so suit yourselves. Overall, if you're in the US and want a good flagship Android that works with 2 of the major carriers on both 3.5G and 4G LTE (and don't care for Verizon's coverage), get this phone... Just beware that you do need to get a fake IMEI activated if you're on AT&T and don't already have the "true" 4G LTE data plan, otherwise the system will simply restrict your ZL to HSPA+ (Basically, you need to find a friendly store rep who can put the LTE plan on your account using a spare phone that is recognized as a 4G LTE handset by AT&T's activation system.) For me, having good LTE in major cities and DC-HSPA+ when on major interstates is more than sufficient, and having truly unlimited data + LTE on this phone is a must-have.

Cons: The viewing angles are somewhat a con for those who are into that I suppose..

Pros: - *Phone is very fast and hardly lags. Switching between screens is a breeze. *Super sharp excellent screen that beats most high end phones currently. *LTE, and can go either T-Mobile or AT&T *Doesn't come with a lot of installed junk. There is about 10-11 gigs of free space available when you first get this phone. *Remote control works great! I just selected my brand of TV, tested the controls, and it worked right away! This is both for my TV and top Cable-box.. it worked on both! *I love the extra bar that has popup apps *Was easily updated to Android Jellybean 4.2.2 as soon as I powered up the phone. It automatically asked me if I want to update as soon as I have it set up on my wi-fi network. *That little notification light at the bottom of the phone looks really sick (in a good way). *Takes excellent photos and videos. It has a dedicated button for taking pictures! *After updating to Android 4.2.2, it will now support 64GB microSD cards now too! Make sure you get a class 10 though. *Has stamina mode that works and saves you some battery power. *The phone charges pretty quick plugging it directly on a power source. From 50%, I got back to 100% in about approx. 30 mins or so.

Cons: - *The sound lacks depth and *boom* factor. Don't get me wrong, it can play loud but the quality isn't what I was hoping for. Maybe its just I'm so used to my surround system. I have a more pleasant experience using the earphones though as the audio sounds much better. *If you set the brightness high and uses a lot of apps that runs in the background, this will zap your battery pretty fast. *It comes with a pre-applied screen protector that is not meant to be removed. The screen protector it comes with is easily scratched so I suggest you buy another screen protector to put on top of it. Don't worry. Putting another screen protector will hardly degrade the quality of the screen as long as you put a good one. I used Skinomi on mine. It uses wet application method but I think this technique is easier than dry application ones. Just watch the vids online how to put it on. *Some might find the position of the front facing camera odd but this really doesn't bother me much. *If you are considering buying this phone, I'm sure you have read/watched reviews regarding its "bad" viewing angles. Don't pay attention too much to these reviews. The viewing angles isn't that bad. Sure it might degrade a little but not that bad at all. I mean, who actually does look on their smartphones sideways all the time? I showed pictures and videos to my co-works and they all can just see it fine and they're standing at my side. The screen is crystal clear and really sharp... and this with a 2nd screen protector on top of it.

Overall Review: This phone is more than enough for my needs at the moment. I just want a reliable and powerful phone. I didn't get this phone for gaming or reading. This is meant strictly for making/receiving calls, texting, and occasional web browsing. I also have some apps installed like organizers and reference guides to help me with my job. For gaming, I have a dedicated device for that--the NVIDIA SHIELD. I'm planning to install a lot of emulators and games on this device. This will strictly be for portable gaming. For reading and web browsing when I'm not at home, I have the Nexus 7 (2nd gen). It will be nice to have a one device that does everything good. But for now, I think these 3 have me covered pretty much. For hardcore gaming.. of course.. nothing beats an uber PC. I hope this review helps in making your decision! ;)

Pros: I went from a Samsung Galaxy Nexus to this and boy what a big difference going from a mid range phone to a flagship model. Unlike most reviews that I've read online about the screen washing out and bad viewing angels, I feel that they are way off. After using this for several weeks, it's my summation that those reviewers must have been paid by Samsung and Apple to write less than pleasing reviews. As for battery life, I've been testing the "Stamina" mode and must say that I can go about 2 days without charging. Now granted, I'm not a heavy user and don't look at my phone every 10 minutes. The stamina mode turns of the wifi and data radios to conserve battery life *WHEN* the screen is off; the phone is "sleeping". Phone calls and text messages still function without a miss. When you wake the phone up the radios turn on, emails and other data required items work without missing a beat. I really like the tactile feel of the back. I gives an anti-slip feeling unlike the all glass back Z model. As for price, some think it's too high, well, it is Sony's flagship phone and some manufactures would charge $100 to $200 more.

Cons: I haven't come across anything as of yet.

Pros: AMAZING Screen - Seriously, don't listen to reviews you have to see it to believe it. FAST - It seldom lags, if at all. COMFORTABLE - The phone just feels so great in the hand, the back cover is a rubberized texture that allows your hand to just relax and the phone ain't going anywhere. It's also the smallest 5" smartphone you can buy, period. AUDIO - This phone has something called ClearAudio+, which is similar to Beats but without the gimmick. It truly adds depth and clarity to music, especially with earphones. LED NOTIFICATION - This little detail makes me giggle with joy at how clever it is. When viewing photos or playing music, the light will change to the color of the image or pulse with the rythm of the music. It's also really big so you won't miss calls/emails/texts. There's more, but it would take up at least 2 paragraphs.

Cons: VIEWING ANGLES - Okay, I will admit the phone has bad viewing angles. HOWEVER, they are not as bad as reviews make it out to be. If you are expecting to read emails and texts while the phone is 3 feet away from you while tilted, then yea this isn't the phone for you. HEAT - The phone doesn't get too hot, but it does get warm when watching movies or playing games. Add that to the rubberized texture and I found my palms getting sweaty.

Overall Review: While this phone isn't perfect (no phone is), I do find myself liking it more than the HTC One. That phone just seemed to have way too many problems and HTC has burned me in the past so I'm done with them.

Pros: Smaller form factor with 1080p screen. For my needs, this phone has it all. It's fast, has plenty of memory, supports SD card expansion, battery life is above average, supports all protocols/frequencies for T-Mobile. If you don't like the giant size of today's premium android offerings, but don't want to compromise on features/quality this is a pretty good way to go. Just ordered my wife one too.

Cons: Non-removable battery, as others have stated. Not much of a con for me.

Pros: -LTE support for ATT and T-Mobile -IR blaster works wonderfully -Dedicated camera button -Beautiful Screen -Small form for a 5" screen

Cons: -As other reviews online state, poor viewing angles -Battery seems to drain quickly when not using power save mode

Overall Review: The 2 cons really didn't bother me at all and I knew to expect this prior to purchase. The Xperia apps are good and Sony's skin for android looks pretty good. Word of caution for people wanting to use this on ATT's LTE network. You will have to call in to customer care and provide an IMEI number for an ATT phone that can be provisioned with ATT 4G LTE or have previously used a phone that had a LTE data plan.

Pros: The screen\dislpay is beautiful also viewable in daylight better than my s3 Well made device. IR port, has remote control software so you can control your TV, tuner, satellite, cable etc. With the smartphone :) Size you can actually use this 5 inch device with one hand unlike the Z and many 5 inch devices. Very responsive nothing lags, battery life is no issue especilly if you use the built in battery saver modes.

Cons: Removable battery, more cases that don't cover the IR port

Pros: Very fast and smooth, I work outside and the screen in the sun is super. Great phone ++

Cons: None
