Use the emulator that comes with the Android development kit. Cost: $0. The only point of testing with a physical device is if you want to check the compatibility and ergonomy of your application with a physical device: how it makes use of non-ubiquitous peripherals such as a fingerprint reader, how it interacts with manufacturer-specific software, etc. ...

The newly (August 2015) announced Motorola X Pure Edition costs $400, well below your price range, yet is a high-end modern smartphone. I think European branding is Moto X Style. 5.7" 1440p Quad HD display and front-facing stereo speakers (515 pixels per inch - better than Retina). 21 MP camera 3GB RAM microSD card (up to 128) This phone matches and ...

Look at Xiaomi (world's 4th largest smartphone maker) for reasonably priced phones with good specifications , they are often hard to beat price-wise. E.g. the Xiaomi Redmi 2 Pro Smartphone meet all your required specifications and costs ~130 USD: 4G LTE, 2GB RAM, 16GB memory, MSM8916 64bit Quad Core 1.2GHz, Android 4.4, 4.7 inch HD OGS Screen, Dual Cameras. ...

The Moto E is a low end cell phone priced at ~$120 USD for the 3G model (off contract). It has 1GB RAM, 8GB internal storage, supports up to 32GB microSD, and Android 5.0. The display is 4.5" qHD 540x960 245 ppi IPS. The 3G model has a 1.2GHz quad-core CPU (Snapdragon 200) and an Adreno 302 GPU (400 MHz). Also, if you order it from Motorola directly, you ...

General guidance for buying cameras alone can be applied here. There are several important aspects: Pixels This is the resolution that the image sensor is capable of capturing. The greater the number, the more detail you'll get in your image. This does, however, combine with the next point: Sensor size The bigger the sensor, the bigger the pixels can be. ...

Well, based on your preferences, I would definitely recommend OnePlus 2. One of my friends bought it, and it's really awesome with the best features and at a reasonable price. 13 MP with dual flash and of course laser-focused 4 GB LPDDR4 RAM Adreno 430 GPU Octacore CPU, good for gaming Comes at € 399. The only exception is you need to Buy with an invite. ...

The Samsung Galaxy S6 Active is essentially a rugged version of the Samsung Galaxy 6 with a better battery, so I think that would be well suited to your needs. A review of the S6 Active is here. If that is above your price range, apparently CAT makes phones now: http://www.catphones.com/ The S50 actually seems like a decent phone at a reasonable price, so ...

Just pick up a cheap prepaid/no-contract Android phone like the LG Optimus Exceed 2 or Moto E. The Exceed 2 frequently goes on sale for as little as $15-$20 and has a dual-core CPU and 4 GB flash. The Moto E often goes on sale for $40 and has a quad-core CPU and 8 GB flash. I bought one for $10 on Black Friday 2015. The camera is garbage but otherwise it ...

I found one additional phone which meets almost all your requirements (and is not Asus Zenfone 2 or Asus Zenfone Zoom or other Asus). Lenovo K80 CPU: Intel Atom Z3560 (x64 quad core processor, but only 1.83 GHz frequency. It's the same processor like in Asus ZenFone 2 ZE550ML.) GPU: PowerVR G6430 2 GB or 4 GB RAM (it depends which version) 5.5" LCD IPS ...

Your best bet is likely to be to get either a smartphone with interchangeable batteries and carry multiple ones, or get an external power pack. A limited sample size survey of a number of smartphones show that for web browsing, the best performer (iPhone 6) drained 35% battery in 150 minutes, which implies a 7.5 hour battery life for web browsing over WiFi....

I, and my son, both have Samsung Galaxy S4 Active and its survived all the things you were wondering about. You can get them at a very reasonable price on the worlds largest online vendor but make sure you get one that is compatible with your phone provider. You probably don't need the extra features that come with the S6 and if you manage to destroy a $200 ...

I recommend using a SanDisk MicroSD card. They're probably one of the most popular options, and for a good reason, too. They're very reliable, and not too expensive (Especially the 64GB one; The 128GB is newer technology, so it'll cost more per GB). I've used mine for years, and never had any problems with them. It might be tempting to buy a really cheap ...

I'll keep this as short and as on point as possible: Get the Samsung Galaxy S4 because it is a great android phone with awesome specs, but in a tight budget of under $180(may go a little over). Typically $130-180 unlocked second hand, $150 on a quick amazon search for Straight Talk. New for $208. Apparently $150 new at Walmart for Verizon. It ...

The general list of features you should consider has been pretty well covered by others, I will tackle this from a slightly different angle: Just how important is the camera to you? Is it more or less important than the phone features, or the phone OS for example? There are options that prioritize the camera over the phone, like the Samsung Galaxy S4 Zoom. ...

As mentioned in the comments, some Android phones will come close, especially if you root/modify them afterwards. There is an alternative that has not been mentioned, from the Mozilla organization: Firefox OS. I have only used one of these phones briefly (for a couple of hours) personally, but I know others have used them successfully and enjoyed the open ...

Practically the only android phone I can think of that's got a keyboard these days is a blackberry. Specifically the priv. It runs newer versions (6.0 is coming soon(, and flagship specs - it runs a Qualcomm 8992 Snapdragon 808 Hexa-Core. Not the latest and greatest but reasonably solid, 3gb ram, and seems to have some privacy centric addons.

If you have an Android it's very simple, you don't need any apps or external devices. Just go into the call settings, and scroll all the way down. There are the Internet call settings, where you can directly log in to your VoIP provider and answer calls wherever you have an internet connection (make sure to check the Receive incoming calls check box). I use ...

There are several great brands that make Micro SD cards, including, but not limited to SanDisk Lexar Samsung PNY Kingston I read here that Samsung and SanDisk tend to make the best micro SD cards in terms of performance, but the difference is not much to look into. Realistically, they will all serve you well, so if you do find a really good deal on a ...

Sony's Xperia Z3 Compact and Xperia Z5 Compact are about the same size as the iPhone 6 (not plus). They also seem to be the only (as of beginning of Oct, 2015) high end Android devices with screens under 5 inches. Sony's Z3 and Z3 compact have some very excellent battery life compared to other Android manufacturers. The Z5 compact is expected to be released ...

As said in the comments, if you care about the battery life then look at the number of mAh the replacement battery has. The Samsung original battery for Galaxy S4 Mini is 1900 mAh so you want something higher, e.g. Zerolemon Samsung Galaxy S4 Mini 5100mAh. Beware that some batteries are too thick to fit in the original phone case, so they come with a thicker ...

I personally ordered the OnePlus Two, but to be honest I would go for the ASUS Zenfone 2 (version: ZE551ML, that's important!) if you can live with some bloatware (not that much) because: It costs 300-350€/211-255£ and it's sold on Amazon. It has 4 GB RAM. That's plenty of RAM for gaming The processor (Intel Atom Z3580) is quad-core clocked at 2.3 GHz ...

Blueproducts has a great product line, I guarantee they will have a design you like. There are so many to choose from so I won't go into much detail here. I personally have the Blu Studio 5.0C which is a bit older now but when I bought it brand new a year ago, for $125 plus shipping, it exceeded all expectations. Android (4.4) 5.0 inches 720 x 1280 pixels ...

For development it is a good idea to get a high-end phone. The nexus 5x is a high-end phone for a great price. It has a front facing speaker, 5.2 inch display with a 1920x1080 resolution. The CPU is a Snapdragon 808 and has 2GB of RAM. The phone is running android 6.0 and will continue to get updates for the next 2 years. A good reason to get a nexus for ...

In my opinion Xiami RedMi 2 Pro is much better choice than SGS4. Below I present pros for both phones: Xiami RedMi 2 Pro it's new it has LTE it has DualSIM it uses MIUI OS which has regular updates SGS4 better screen (AMOLED 1920x1080) better camera it's cheaper CPU and GPU are similar in this models maybe a little better in SGS4. The biggest advantage ...

The new Blackberry Priv runs Android and has a physical keyboard, 4K display, Snapdragon 808 and 3GB of ram (so it should not be slow). Its the closest thing from what you are looking for I guess.

Oh my, a question targeting my hardware experience AND my more than passing interest in cognitive science! I have a friend who is currently dying from Muscular Dystrophy. In the end stage of this disease, he is barely able to move any part of his body. He and I investigated several consumer-grade EEG devices as a means of him controlling computers (none ...
