New devices updated last week

Snapdragon Processors: Combination of features and performance.

Author: Encarni

Snapdragon is a system on a chip (SoC) product family by Qualcomm, targeted to smartphones or tablets. This company has long been one of the benchmark companies in mobile devices. Lately they have become a leader in producing SoC for mid and high end smartphone and tablet devices.

The use of the Snapdragon 410 (MSM8916) chip is still very high. During the last two years it has been one of the most popular processors in mid range smartphone and tablets. More importantly, big brands continue to create new devices with this chip. This processor has a powerful combination of features, performance and battery efficiency. These include integrated 4G LTE, the support of up to 1080p resolution, a 13 megapixel camera and the inclusion of an Adreno 306 GPU.

Last week 51degrees added different devices with Snapdragon processors.

API Version 3.2 Update for Developers

Details of features and release schedule for API updates

We’re always working hard to improve the 51Degrees APIs making them easier to use, consume fewer resources and provide new features. Version 3.2 combines many incremental changes. Highlights included in all API variants are:

  • New version 3.2 data file is 25% smaller than version 3.1. Data file size is no longer proportional to supported Device Combinations and Signatures. As a result V3.2 data files will grow at a slower rate than V3.1.
  • C APIs now join PHP, .NET and Java in supporting multiple HTTP headers, not just User-Agent. The developer no longer needs to consider which headers to use.
  • Cache structures are now all memory limited rather than time limited resulting in a more consistent memory profile.
  • Information relating to false positives such as rank information is returned more quickly.
  • Github is the master repository for all API source code. Mirrors will be maintained on Codeplex, Sourceforge and other locations.

Apple Standalone on Device Detection

Exposing the crippling solution used to detect iPhone and iPad models

Device vendors as varied as the mighty Samsung, to brands like Pantech and Micromax all recognize the importance of identifying different device models when accessing web sites. However Apple do not fully support this approach.

Some device detection solutions have tried to address the problem by artificially stressing the iPhone or iPad to determine how quickly its processor can complete iterative tasks. Understanding how the device performs under stress provides an indication as to the CPU available and therefore the model of device. The approach can yield more information but ironically at the expense of user experience as the page load time increases and the battery is drained more rapidly.

If every web site were to stress iPhones and iPads to gain model information the web would slow down for Apple users. This isn’t in Apple’s interest. However if Apple make a simple change the problem can be avoided.

Device Detection for Apple iPhone and iPad

Which techniques to use and avoid

51Degrees data analysis team stress tested a range of real iPhone and iPad devices, both old and new using all the major web browsers in order to determine if CPU stress testing is a viable additional method to identify iPhone and iPad models alongside User-Agent analysis and screen information.

The full results are available for download along with analysis of the differences for each device and browser.
