Unboxing and tour of the new AT&T Microsoft Lumia 640 XL

Starting late last week, those on AT&T were finally able to get their hands on the Microsoft Lumia 640 XL. The phone features a rather generous 5.7-inch display and by all accounts it is a winner. We managed to pick one up and figured we would unbox it and give you the full tour.

We already reviewed the Lumia 640 XL for Europe. However, this one has LTE on board and obviously works on the AT&T network. Retailing for $249 off-contract or just 99 cents on, I have to admit that this is a really nice phone. Indeed, the 5.7-inch display seems to be the sweet spot between typing and carrying it around.

  • The rear camera shoots in raw, yes?
  • Nope, that is a PureView thing only. It may get it later on, but so far it does not have that (unless it's in the Beta app).
  • The camera is not good enough to justify saving in raw anyway.
  • Yea I bought it and I love the front facing, the back, ehh its no pureview that's for sure, but outside with lots of light its ok
  • I wanna see one of these in the wild... I need to prep my hands fir a 5.7inch device. I had a quick play with a friend's Note 4. Practiced taking it in and out of my pocket. I think if MS had gone for the 418 (or whatever it is) or the 615 Snapdragons then these would be perfect. They look really nice.
  • Prep for a tiny 5.7" device.... Lol❕❕
    ....
    I didn't even have to prep for my 1520, and it's at a perfectly normal 6".... 5.7", give me a break.
    ....
    This device, and the two rumored high end devices, are terrific, and 5.7" is great❕
    But, a lot of us are really hoping MS has some sense, and the balls, to give us a real 1520 replacement... We need some 6"-6.5" super Lumia's to replace our current 1520's.. Anything smaller is just.... Meh.
  • I'd like to see some 6" or 7" options but I want Microsoft to add some features to take advantage of the larger screen. Give me full landscape support throughout; more apps with two-pane views, maybe even split screen apps; stylus support. Or just give me a 7" Surface Micro.
  • Exactly.
  • Quick question: how did you resolve the 1520 touch screen issue. I got mine used and am only thinking of the 640XL because the touch screen issue bugs me to no end. Because it was used, I couldn't "return it" by the time I learned it wasn't just me or my usage habits but a real problem with the screen.
  • Most issues have been resolved with updates back in 2014.....
  • Not sure which updates or how I missed them. I purchased the device used in April. I've gotten every single update that I am aware including the one pushed out from AT&T just recently. My issues haven't been resolved. A swipe still registers as a tap 50% of the time and Tap to Wake is also 50/50. And since the AT&T update, even "Hey, Cortana" stopped working.  As much as I love the camera on the 1520, those "quality of life" issues are bugging me and making me seriously think about the 640XL.
  • Have you tried turning screen sensitivity down?
  • Thanks for responding.  Turning down screen sensitivity was my first step. It helped some, bringing it down to 50%. I understand it was later devices that didn't have that problem but from the research I've done, people have sometimes had to go through several (or gave up and went to another device) before hitting that magical "later batch" where the issue was resolved. Since I purchased mine used, I didn't have that luxury. 
  • I hadn't thought of that.  It is helping me a lot now.  I think it might be enough to tide me over until a real 1520 replacement is available. Thanks!
  • 3 here that NEVER got fixed. Sold them all.
  • Eh. That touch screen issue was a nightmare.
  • NOT EVERYONE HAS BIG HANDS LIKE YOURS. So stop making fun of the commenter.
  • What are you talking about❔
  • Was really hoping for a 15xx, but with the 940xl's removable battery and 5.7 screen, I'll manage somehow. :) I really hope WP OEMs pick up the removable battery scheme now that Samsung has dropped it in the S6. Glass looks nice, but its disheartening to seen all the OEMs moving to exclusively monobody builds. Device batteries just aren't good enough to last more than 2-3 years without significant depreciation in power storage.
  • Are you saying the companies we buy our phones from are taking out the ability to simply spend $50 and have our phone good a new? Rather than purchasing a $600 smartphone? Inconceivable!   I'm just being sarcastic =) But at the same time it wouldn't surprise me if that's exactly how these companies think! Granted when all anyone every talks about is "I want thinner!" there are only so many place to cut down on thickness, and a removable battery is one of them.
  • Isn't there going to be a 940xl something that is more in line with 1520 size and specs?  I hope it will be available soon because I'm starting to have problems with my 1520 display jumping around and phantom touches.  I can clear it by locking and unlocking the screen but it is starting to get really annoying.  What is the latest on the rumored 940xl please?
  • It's nice to know I'm not crazy, my 1520 started doing that as well to the point where it became unusable.  Jumped back to an iPhone 5s until I see what the new flagship is going to look like.
  • @Cy, I'm really thinking of jumping to the 640XL, while not unusable, my 1520 is getting on my nerves with the touch screen issues. I keep asking around because I hear later batches of the 1520 fixed the problem but I've yet to get any confirmation or which model number to look for.
  • It looks horrible.  So much wasted space and that casing showing at the front is just horrible.  Ugh I hope their new flagships don't look this bad.   I think the 930/830 are the best looking phones released for Windows phone thus far.  Even the Blu Win HD one looks pretty decent.  I played around with them in Microsoft store.  Heck the Yezz Billy looks better too.   The rear side does look decent, I'll give it that much.
  • In its defense, it looks like a 600-series Lumia. They've always had this design and shape. It may not be the fanciest look out there, but it still is a budget phone.
  • Go show us a $249 off contract phablet that is available in the U.S. that has great styling. I can say that I'm really impressed with my new 640 XL. Sure, it's not flashy, but it does everything well. The 740 and 840 will probably add at least SD 410 or possibly SD615 with 2 GBs of RAM. The question, of course, is what will MS charge. Unfortunatetly, the 840 will probably go for $399 which will be too high. Finally, It's reasonable to assume that MS had to stay committed to the Nokia styling up through the release of the 640. It's possible that the 740 / 840 will continue along this track with the real departure in terms of styling coming with the 940.
  • I'll give you one that should be 249. The iphone 6 plus hehe
  • now you are talking
  • Not better than the 8X
  • 930/830 were OK, but IMO the edges were too sharp. 640's are too curvy like the iPhone 5C. The 92X and 1020 really nailed it on edge curvature;nothing was too sharp or overly rounded, and the device could stand up completely.
  • My locoal AT&T store had a display model on the floor the same day it was released. Even if you don't buy it from them, at least you can visit a store and play around with it.
  • Just wait for the 949 XL (it also packs a 5.7 QHD SCREEN) it has much higher specs then any other windows phone.
  • i haven't watched the video yet since i'm at work, but if you haven't, can you show a comparison in terms of size with the 1520?
  • It's just a little smaller than the 1520. I mean you need them next to each other to notice.
  • 1520 is just a hair taller, but it is thinner than the Lumia 640 XL.
  • wow this thing is a beast for a 5.7" phone then if 1520 is 6" screen.  i hope the new flagship Lumia with 5.7" screen is more compact
  • Well that's why it retails for less than half the price of the 1520... Among other reasons.
  • If you've ever used a Note4, and a 1520, then you know that .3" is not just a little smaller...
    ....
    On paper it sounds like not much, but in reality it makes a big difference... Don't listen to anyone who doesn't like larger devices, and has never used on... Of course they wouldn't think it's not that big a deal, and I hate it when the dismiss the fact that nothing is like having a full 6" device, but a full 6"-6"+ device... We should be going higher, not lower...
    ......
    Nevertheless, I do like the idea of a 5.7" device, and I think it is necessary... But, I hate the one size fits all BS mentality... We also need 6"+ Lumia's..
  • I have to agree with this. I have both the 1520 and the 640XL (Dual SIM). The typing experience on the 1520 is just so much better. And as Daniel mentioned above, the 640XL is certainly chunkier than the 1520 which make the latter somewhat easier to handle counter intuitive though it may seem. But I have to say this - the 640 XL is a fantastic device in its price range and I do like using it a lot.
  • Yeah 6.5" is the sweet spot for me. I used a friend's xperia z ultra for a while and it was great.
  • I would like a 32" Lumia with a decent camera
  • Sometimes I run a 46" one, lol.
  • I picked two up on Friday. After a weekend of use, my wife declared that she loved it. We went with the next 12 plan since it's cheap and next summer we can move to a new flagship phone while saving some money in the meantime.
  • att best windows phone right now aside from 830.
  • Better as the AT&T 830 *still* hasn't the full denim firmware updates. Great little device, but Argh!
  • i wish they would hurry up and release the 640.....
  • Not going to happen on ATT.
  • I bought one for my mom over the weekend. I personally own a 635, 830, 930, and 1520, and I'm still jealous of this phone! Easily one of the best values in the Lumia lineup yet.
  • I have the international version of the 640XL LTE that works fine on AT&T network. Belongs to the wife. She loves it! Good phone at a great price.
  • Windows phone is probably the only UI that can get away with that low of a PPI and still be "acceptable". That's kinda rough though. But I can afford better, many can't, so... I'm sure they'll love it. Posted via the Windows Central App for Android
  • It would be less noticeable with OLED, but it is a budget phone after all...
  • Hmm. I might need to make a trip to the Microsoft Store and see these first hand. I was mighty impressed when I got a hands-on with the Lumia 640 at the local Cricket Store. Maybe if this fills the couple little holes I found in the 640(which is only really the camera), I might consider grabbing this outright and switching to Cricket. Only thing is I dig T-Mobile and Legere's fight and cause more. It would be hard to let go of T-Mobile... Maybe I should just wait for the Lumia 940 (or whatever they call it).
  • For this phone, the popular option I've been reading from T-Mobile users was the dual SIM unlocked version. I just got an email from Expansys today stating that they've dropped the price on it to $220. Might be an option for you. :)
  • No WiFi calling and VoLTE on non T-Mobile phones though.
  • I've seen people who bought the unlocked version from Expansys post that TM Wi-Fi calling does work with the dual SIM version. Model #1096. 
  • Hey I'm not disputing that but don't you have to have the Tmobile WiFi app? I use a note 4 and would love a phablet to replace my ATIV S Posted via the Windows Phone Central App for Android
  • The only two issues I discovered is 1) using MS/Lumia Camera it takes 2-3 seconds to save and 2) using rich capture, when I try to edit in th Camera Roll under Photos, the option is not there. I have everything set to save to SD (64gb san disk XC Class 10).
  • yeah, Rich Capture is painful with this processor.
  • I'm on att with a dual sim unlocked. I picked it up about a month ago at Overstock and love it! Got the orange and picked an extra cover on eBay for $10 bucks in black OEM
  • I still thinking that this is a sidekick to my lumi 1320, stil running smooth. So i am in the wait for something bigger. Good
