Ever aback Microsoft bought Nokia’s adaptable accessory division, the Lumia band of Windows Phones has been absorption on affordable smartphones that still accompany a lot of good-enough appearance with beneath compromises. This is apparently a adequate strategy, aback I’m abiding a huge allotment of the citizenry doesn’t charge an $800 iPhone for texting, Facbook, and Instagram. The Lumia 640, is one of the aboriginal Lumia smartphones to assuredly accommodate Microsoft’s own branding, and it removes abounding of the compromises you ability accept to abide on added bargain annual smartphones like the Lumia 5XX alternation and alike the Lumia 63X series. Read on to acquisition out about this new sub-$200 Windows Buzz 8.1 smartphone.
The Lumia 640 has a Quad-core 1.2Ghz Snapdragon 400 SoC processor with an Adreno 305 GPU, 1Gb of RAM and 8 GB of centralized storage. About bisected of that is taken up by the operating system, arranged apps, and your synced email accounts data. That’s not a lot of allowance for actual abounding 3rd affair apps, music, pictures, and videos, so thankfully a Micro SD aperture is beneath the array cover. You can add up to 128 GB of accumulator that way and what’s accomplished about Windows Buzz 8.1 is that you can now move or install apps to the SD card.
The phone’s admeasurement is a admirable 141.3mm x 72.2mm x 8.8mm and the weight is 145g. The awning is a ample 5 inch Gorilla Glass 3 ClearBlack IPS LCD console with a 1280 x 720 pixel resolution which translates to a book affection 294 pixels per inch. It’s got an ambient ablaze sensor, accelerometer, adjacency sensor, magnetometer, and SensorCore for excersize tracking. The 8 megapixel behind aflame camera on the aback has auto-focus and an LED flash, while the advanced adverse camera is alone 0.9 megapixels. It’s all powered by a 2500 mAh battery. This accurate adaptation is the one fabricated for Cricket Wireless, but there are additionally apart and dual-SIM versions.
Those are some appealing appropriate specs for smartphones in this amount range. The alone high-end things you’re absolutely missing are NFC, wireless charging, and a college end camera with added resolution and optical angel stabilization.
The Lumia 640 absolutely feels nice in the hand. It’s thin, it has collapsed edges that are accessible to grip, and it’s got a abundant attractive cyan dejected clear-cut array cover. It is actual agleam and glossy though, so you’ll be wiping off feel prints and duke oils appealing frequently. Aback it’s too thin, it becomes difficult to authority and use but the collapsed edges absolutely advice in this regard.
The 720 x 1280 pixel awning has affluence of pixel body for aciculate print-quality viewing, but its adverse fades a bit aback examination from acute angles. That’s apparently alone activity to be an affair if you’re aggravating to use it to watch a cine with 4 of your friends, but still the awning is actual tolerable. It’s absolutely clear outdoors as well, which is not so accurate with article cheaper like the Lumia 530.
On the appropriate ancillary there’s a ability button and an up/down aggregate control. The buttons are accessible to acquisition with your fingers and they’ve got abundant concrete feedback, but they absolutely don’t accept a exceptional feel. They’re aloof simple bogus buttons. A committed camera button is missing, which is acutely unfortunate. To barrage the camera, you’ll accept to pin its asphalt to your alpha screen, or add the camera quick activity to the Activity Center. Unfortunately, the activity center’s top-edge awning action is actual ailing placed at the top of the screen.
On the top is the 3.5mm angle jack and it sticks out a bit over the angled edges of the array cover. This is the atom breadth the clear-cut array awning absolutely looks the coolest.
There is a front-facing camera on the Lumia 640. Often smartphones in this amount ambit tend to lose out on appearance like that, but it’s abundant to be able to do video calls aback the charge arises. The resolution is actual low though. You’re not activity to booty abounding amazing selfies with this.
The Lumia 640 absolutely includes Glance Mode. This is addition alarming affection that’s usually begin on higher-end Lumia devices, but it’s assuredly accessible on article added affordable. Glance Approach shows some buzz advice and the time on your awning in a low-power accompaniment aback it’s in beddy-bye approach so that you can bound see some important being afterwards axis the accomplished buzz on. Unfortunately, this is the old adaptation of the Glance Approach software which alone shows the alarm and notification icons. It does not appearance any abundant cachet information, the date, or accomplishments lockscreen app data.
On the aback is the 8 megapixel camera and LED flash. It’s adequately alike with the array cover, but there’s a slight rim that you can feel with your fingers. That’s a adequate affair admitting aback you’ll be able to acquaint aback you’re affecting the lens and accepting feel prints all over it.
Thankfully, the array awning is disposable as is the battery. The array is a BV-T5C archetypal with 2500mAh capacity. Additional batteries of this blazon are difficult to find, but there are some on eBay for $27 with a $48 aircraft fee. That is abundant added big-ticket than the additional batteries you can get for the Lumia 5XX alternation (BL-5J) which you can get for $5 with chargeless shipping. Additionally begin beneath the array awning is the Micro-SIM agenda aperture and a MicroSD agenda aperture for accretion the storage.
You’ll additionally apprehension some bogus indentations abutting to the SIM agenda slot. This is breadth the Dual-SIM adaptation of the Lumia 640 would accept a additional SIM agenda aperture for enabling two adaptable carrier accounts at the aforementioned time.
The Nokia Lumia 640 ships with Windows Buzz 8.1 Update 2 as able-bodied as Nokia’s “Denim” firmware. You can apprehend added about the operating arrangement in our Windows Buzz 8.1 analysis as able-bodied as our Windows Buzz 8.0 review, but there are a few new things in the adaptation of the operating arrangement on the Lumia 640 that we weren’t able to analysis in our aboriginal review. For example, there’s a new affection breadth you can bifold tap a bare breadth of the basal toolbar amid the back, start, and chase keys and that will put the buzz into beddy-bye mode. Combine that with the double-tap to deathwatch affection and you don’t absolutely charge the ability button anymore. The settings are additionally organized differentlly and there’s a chase acreage for bound award the ambience you appetite to change. Bluetooth keyboards and Miracast affectation wirelessconnectivity are additionally now supported. This Cricket branded archetypal additionally includes a brace appropriate apps for use with the Cricket service.
The “My Cricket” app shows up on aboriginal cossack appropriate in the boilerplate of the alpha screen. This is a appropriate annual administration app for the Cricket service. It lets you administer your service, appearance abstracts usage, pay your bills, add/remove annual features, set up / administer Autopay and acquaintance chump care. It additionally has a alive tile, so that’s nice.The blooming “Wi-Fi” figure abutting to it is addition Cricket app that lets you chase for adjacent Wi-Fi admission credibility that you can affix to as allotment of your Cricket service.
The 8 megapixel camera on the aback of the Lumia 640 is absolutely a cogent advance over the Lumia 630’s 5 megapixel camera. For one, it supports Lumia Camera 5 with alive images and affluent capture. Affluent abduction can be actual useful. Instead of aloof some canned HDR mode, affluent abduction does a agnate affair by demography 2 or 3 photos (maybe one with the beam on) and amalgamation them. However, you can accept “edit affluent capture” afterwards the actuality and change the way the images were merged. That agency you can absolutely change the lighting altitude of your photo afterwards you’ve already taken it. It’s acutely cool. Additionally clashing added HDR modes, a aeroembolism antecedent book with the aboriginal JPGs is accessible in the phone’s memory.
In the aloft 100% crop sample we can see how the Lumia 640’s 8 megapixel angel compares to the BLU Win HD LTE’s 8 megapixel angel (which is addition Windows Buzz in the aforementioned amount range). The Lumia acutely has some bogus cutting clarify activated as you can see by the light/dark edges forth the buildings, but the advance in the lower larboard is absolutely clear and there seems to be actual little noise.
Take a attending at the abounding resolution camera samples below. The aboriginal two use the low resolution advanced adverse camera and you can acquaint that the affection is severly lacking, but it’s bigger than annihilation at this price! The abutting 7 samples are ablaze alfresco shots and the Lumia 640 does absolutely able-bodied with those. It’s not 41 megapixels good, but with alone 8 megapixels to assignment with, they’re absolutely acceptable. The aftermost two are low-light photos, while the aftermost one uses the LED beam forth with “rich capture” mode. The LED beam is acutely not actual adequate at lighting up a room. It’s apparently alone activity to be alike accidentally advantageous at about arm’s length.
The Lumia 640 denticulate 245.07 in WPBench, compared to 218.14 on the Lumia 630, 169.25 on the Lumia 521, 234.73 on Lumia 928 or 232.11 for the Lumia 925. The Lumia 640 absolutely performs bigger than alike some of the beforehand high-end Lumias in the benchmarks.
In WP Bench’s array activity analysis beneath connected CPU stress, the Lumia 640 lasted for about 3 hours 57 minutes. That’s an hour added than the Lumia 630, and in absolute activity with three or so advance email accounts added you’re activity to aftermost able-bodied through a day and maybe 1.5 days. As mentioned earlier, the BV-T5C archetypal array with 2500mAh accommodation is difficult and big-ticket to acquisition replacements for though.
Voice calls complete about boilerplate on the Lumia 640. The apostle buzz approach doesn’t assume to be as loud as the beforehand Lumia 520. As for the LTE performance, we got about 4.7 Mbps download and 3.34 Mbps upload (Cricket is basically active on AT&T’s network).
The Lumia 640 is alone $129 from Cricket Wireless with activation. That’s a lot added than the Lumia 635 which is additionally accessible on Cricket for $49, or the Lumia 530 which is $29 with a $30 rebate, but the Lumia 640 is absolutely a far bigger buzz again either of those. Personally, I anticipate the Lumia 640 is appealing commensurable to the iPhone 5c that’s accessible on Cricket for $299, too. The apart adaptation can be begin in the $240 range, and we apprehend otherversions will be advancing to added carriers.
The Lumia 640 has all of the appearance you would apprehend from a smartphone that’s alert the price.It’s got 1Gb RAM, a appropriate 8 megapixel camera, front-facing camera for video calls, a aerial resolution awning with about book affection pixel density, the processor is fast, and it alike has a (somewhat limited) adaptation of the accomplished Glance Mode. It’s absolutely a footfall up from the Lumia 630 and 635 as able-bodied as the 5XX series, and it has a few things that put it advanced of the similarly-priced BLU Win HD LTE. Overall, for the price, the Lumia 640 is a appealing nice deal.
