Mobile Technology

  • HDR Photography: An explanation of ‘High Dynamic Range’ photography – giffgaff
    Recently, I’ve been having a lot of problems taking good quality outdoor photos with the camera on my smartphone. The problem is primarily due to the low-lying winter sun which casts a long shadow. It also gives extreme levels of contrast which are difficult to capture on the small sensor of a cameraphone. On a recent trip to Scotland, I found the only way of taking good-quality photos using a smartphone camera is to enable the ‘High Dynamic Range’ (HDR) feature in the camera. It gives slightly false-looking images but you’re at least able to pick out details in the final image. In this guest blog post I wrote for giffgaff in April, I explain the concept of HDR photography.
  • What to expect from smartphone hardware in 2015 – Android Authority
    A nice round-up (although fairly technical) about the things to come from smartphone hardware in 2015. Key developments include a next-generation processor from Qualcomm which will support faster download speeds with LTE-Advanced technology. There could also be more power-efficient components and a greater amount of storage on Android-based devices.
  • Touch ID LogoBiometric Security: Fingerprint sensors, facial recognition, voice recognition and more – giffgaff
    Since the iPhone 5s introduced a fingerprint scanner for extra security last year, mobile biometrics have grown in popularity. Biometric security is likely to ship on most high-end smartphones in 2015 with key technologies being fingerprint recognition, facial recognition and voice recognition. This guest post, written in March 2014, reviews the current state of mobile biometrics and compares the pros & cons of each biometric security method.
  • Optical Image Stabilisation: Technology to reduce camera shake & to give clearer photos – giffgaff
    The iPhone 6 Plus and Galaxy Note 4 include a clever technology known as Optical Image Stabilisation (OIS for short). OIS gives you clearer and sharper photos especially when using the smartphone camera in low-light conditions (e.g. when indoors or on an overcast day). The technology automatically compensates for shaking of the human hand by moving the camera lens in the opposite direction. I’d expect OIS technology to make an appearance on many flagship smartphones in 2015. This guest post will show you how the technology works.

Mobile Networks

  • Mobile internet: How many GB do you really need? – Ken’s Tech Tips
    Median Average - Mobile Webpage SizeSmartphone tariffs have become increasingly data-centric. The question of “how much data do I need on my smartphone” is commonly asked by readers of this site. At the start of 2014, I carried out an in-depth analysis to work out how much data consumers really need. Part of this study involved analysing the download size of 5,000 of the world’s most popular websites. I’m hoping to repeat this analysis again in the future so we can continue to provide the most up-to-date information in our guide to mobile data. In the mean time, I hope last year’s article will still prove an interesting read.
  • Pay As You Go networks: minimum call charges, per-minute and per-second billing – Ken’s Tech Tips
    A key trend over the past few years has been Pay As You Go networks stealthily increasing prices through the back door. Mobile network operators can quietly increase the prices they charge by adding a minimum call charge or by switching from per-second billing to per-minute billing (i.e. by rounding up the length of your phone calls to a complete minute before charging your account). Last month, we published a comprehensive guide on how UK Pay As You Go networks are charging for their calls. We hope this article will bring some transparency to this rarely-discussed element of Pay As You Go pricing.

    Every year, a large number of people will buy a Pay As You Go SIM card so they’re able to use their phone in emergency situations.

In this article from October, we shine a spotlight on Pay As You Go inactivity and highlight the policies you’ll need to adhere to in order to keep your Pay As You Go account active.
