Samsung have just released their brand new Galaxy S8. This new phone is very promising and has caught the attention of many. It comes with an infinity screen, no buttons on the front, a fingerprint scanner on the back and an iris and face scanner. The S8 screen is a rather big 5.8inch and then the S8+ is a whopping 6.2inch. But they have said it does not feel too big at all. The 12MP camera is very fast and captures things as they happen.

Our team love the addition of the new personal assistant, Bixby. This is a rival for Apples Siri and Google’s personal assistant. Bixby understands speech, text and taps. He even recognises objects through the use of the camera. For example, if your camera shows a watch, then Bixby will search watch and will provide you with other images of a watch and will even take you to Amazon to buy a watch. Overall, it is looking to be a promising phone. Check out more about the all new Samsung Galaxy S8 here.

BMW HoloActive Touch System

BMW have unveiled their latest creation the BMW HoloACtive Touch System at CES 2017. This is an interface between the driver and the vehicle that acts like a virtual touchscreen. So for the first time ever, functions in a BMW car can be controlled without any physical contact with materials. Their system for the driver interface, which behaves like a virtual touchscreen means that your hands float in the air when gesturing to control the vehicle functions. The interior design of the BMW HoloActive is very open and has a living room feel to it. there are speakers within the head rest and each passenger in the car can listen to their own choice of music and films and they will not hear each others. In the back of the car there is a tablet enabled 4k projection screen.

Samsung Galaxy s8

The all new Samsung Galaxy S8 has just been unveiled

So as you may or may not know, Samsung have just unveiled their all new Samsung Galaxy s8. We have heard many leaks recently but they now have the final product ready for you. This is a very strong phone from Samsung.

The first very exciting thing that we are shown about the Samsung Galaxy S8 is the infinity display. While its not all completely screen, it is as close as it can be. It is the ‘biggest and most immersive screen on a Galaxy smartphone of its size’ as said by Samsung themselves. With the S8+ having 6.2-inch curved screen, and the S8 have a 5.8-inch curved screen this is the biggest smartphone screen on the market. However it does not feel unusually large. There is also no longer a physical home button on the front but a virtual one instead. The fingerprint sensor has also been moved to the back and it is located next to the camera. You can also unlock the phone with iris and face scanning.

According to Samsung, the camera on the new S8 and S8+ ‘captures life as it happens’. What this actually means is that it has a 12MP rear camera and an 8MP front camera which are very fast and can capture important moments with no delay. It has the fastest processor to date with a 10nm processor which is fast and increases battery efficiency. You can also expand the memory up to 256GB. With IP68-rated performance you can work through rain and dust. The Samsung Galaxy S8 can be immersed into 1.5 meters of water for up to 30 minutes. With high-quality 32-bit PCM and DSD64/128 playback you can hear music as it is meant to be heard.

The next development on the S8 in comparison to the S7 is the addition of the personal assistant Bixby. Like Apple’s Siri and Google’s Personal Assistant, Bixby understands talk, text and taps. This means that you’re never confined to one method of communication. However you do not even have to talk to Bixby. You are able to show Bixby something i.e. a watch through the camera and Bixby will recognise what it is and search for you. In the instance with the watch, Bixby will take you to Google and show other images of watches or take you to amazon so you’re able to purchase a watch.

The Samsung Galaxy S8 and S8+ were released yesterday for pre-order. Pre-order before the 19th of April and receive it up to 8 days early. The Galaxy S8 is priced at £689 and the S8+ is £779.

Wireless Charging Pad

How does wireless charging work?

So what is wireless charging?

Wireless charging is a way of charging your devices, this being a tablet, a laptop, a smartphone or even devices as large as an electric car, without the use of cables or adapters.

How does wireless charging actually work?

Wireless charging is extremely popular as you are able to just place your device on a wireless charger and it will begin charging, without the use of any USBs or plugs. However, the Wireless charger itself must still be plugged into the wall.

Wireless charging uses magnetism to transmit energy. It uses two coils of wire, one is in the charger, and the other is in the device. The electrical current coming from the power socket at the wall moves through the wire to the wireless charger, this then creates a magnetic field. This magnetic field then creates a current that passes through the coil that is in the charger, generating a ‘fluctuating electromagnetic field’. Then when the device is placed near or on the charger, the coil inside induces the current. This then charges the battery.

How can I get Wireless Charging?

Many smartphones come with wireless charging built into them. The most common brands are LG, Samsung, Google, Motorola, HTC and Sony. If your phone does not come with the ability to charge wirelessly, you may be able to add in the functionality by using a different phone case.

What are the Advantages and Disadvantages of Wireless Charging?

As previously stated, there is now no need for many plugs and USBs which is the biggest advantage as this reduces clutter and makes charging very easy and practically hands free. Also by not having an area full of cables, you are reducing the risk of being shocked by a faulty cable. Another advantage is that by using wireless charging, there are no connectors required which may harbour bacteria, so therefore this is more applicable for medical instruments that need to be battery powered. Lastly, wireless charging really has no health risks, ‘the charger creates a field that is no more dangerous than radio waves, and isn’t strong enough to have any effect on the human body’.

However, there are also a few disadvantages of wireless charging. The main one being that wireless charging is not very energy-efficient. This is due to the fact that it produces a lot of heat. This therefore means that it takes longer to charge your phone.

What should I look for in a Wireless Charger?

There are some features that you should look out for when choosing your wireless charger. Some devices have specific chargers for them, so it is usually best to stick to these particular ones. However, there are many wireless chargers that are usable throughout numerous devices such as the GMYLE, Transparent Acryl Disk Qi Charging Pad which is compatible with most popular smartphone models such as Samsung Galaxy S6, Google Nexus 6P etc.

Something else to bear in mind is the amperage of the charger for the wireless charging pad. The more amperage that the charger has, the faster the device’s battery will charge.

So what is the future of Wireless Charging?

At the moment the most use that wireless charging is having, is by using it at your desk at work, or in your bedroom. However, looking into the future, you could possibly be seeing these wireless pads appearing everywhere. Already, Starbucks have begun introducing this into its coffee shops across the UK after great success in the US. IKEA are even putting wireless charging pads into their furniture.

There are still many developments within Wireless Charging. One of these being to look at the potential of having a charging pad that can charge at a distance. Whereas at the moment the device needs to be touching the pad, or in very close proximity. However, it is possible that one day you could just be in the same room, and potentially be able to charge your device.

Lastly, wireless charging really has no health risks. As the charger creates a field that is no more dangerous than radio waves, it isn’t strong enough to have any effect on the human body.



Tablet Computers

The Best Tablets for use in School

Tablets are becoming considerably more popular throughout schools. This is because students have been accustomed to the touch-screen smartphones for years. This is something that is familiar to them, they feel comfortable with and can use well. Tablets are a good way to capture the student’s attention, and keep them engaged whilst learning, due to interactive activities.

We have taken a look into some of the best tablets for use within a classroom.


There are quite a few Windows tablets to choose from. Windows tablets are not as widely known as the iPad or Android. Microsoft tablets are perfect for work use due to the ability of using Office. Apps for Windows tablets come from the Windows App Store, which supplies the most well-known apps such as Twitter, Facebook, Sky News etc. The last advantage of a Windows Tablet is the fact that you can now use Windows 10 in it, which is Microsoft’s new OS. Windows tablets come with pre-installed apps with Windows 10, these include; OneNote, Mail, Games and more.

Microsoft Surface Pro 4

Microsoft have completely revolutionised the tablet. They have made a tablet that can actually replace your laptop. This includes a 12.4 inch PixelSense screen, which gives a real-life picture quality. The weight is 757g which enables it to be extremely portable and you can therefore work on the go. You can work up to 9 hours uninterrupted due to the long lasting battery power.

The Surface comes loaded with the latest Pro Intel Core processors which make it more powerful than the previous Surface Tablet. You have options of either; m3, i5, or i7 processor depending on your budget. In addition, it is now a lot cooler and quieter when it runs.

This tablet runs Windows 10 and Office perfectly, meaning you can operate your desktop right from your tablet. Lastly, you’re spoilt with pre-installed apps on your tablet, legacy (i.e. traditional) Windows apps and those available from the Windows Store providing an almost limitless amount of apps to be able to use for all of your teaching needs.

This is priced at approximately £749.

Dell Venue 11 Pro 7000 Series Tablet

The Dell Venue is an atom-powered windows tablet. It has been called ‘The Ultimate Business Partner’. It is a laptop is disguise. It has an 11 inch full HD Display, weighs up at 712.14 g and has 10 hours of battery life. You can wirelessly stream HD videos and photos from your tablet to a larger screen. The Dell Venue 11 Pro 7000 series is now powered by Intel’s Core M processors. You have the ability to attach a keyboard to the Dell Venue 11 Pro, this therefore enables you to be able to turn your tablet into a laptop.

This tablet is priced at approximately £463.


iPad’s are probably the most popular form of tablet. When people talk about a ‘tablet’ they generally think of the iPad.

The iPad is loved by both the students and the teachers. It delivers so much opportunity for a memorable learning experience. With an app store that holds over 500,000 Educational Apps, there is something for every lesson taught, all delivering at different levels to cater to the student’s needs. Take a look at our previous blogs: a complete list of Educational iPad Apps, and our favourite educational iPad apps.

The most popular type of iPad for use within in a school is a close contest between the iPad mini and the iPad Air.

iPad Air 2

The iPad Air 2 was released in mid-October 2014. The original iPad Air was 7.5mm in thickness, and now the new edition is even slimmer at 6.3mm with a weight of 469 g and a screen of 9.7in. The iPad Air 2 now has an A8X processor which is still 64-bit and has a new M8 co-processor. The newest feature is the Touch ID button, just like an iPhone. With 10 hours of battery life, this iPad will not need to be charged regularly.

The price of the iPad air 2 is approximately £399.

iPad mini 2/ iPad mini 4

The iPad mini 2 is the most common iPad mini, although there has been a 3 and 4 since then. The iPad mini 2 and iPad mini 3 are almost identical. The only enhancement in the 3 is the use of Touch ID.

The iPad mini 2 has a 7.9in retina display screen with a weight of 331g. With 10 hours of battery life and an A7 chip with 64-bit architecture. The benefit of the iPad mini 2, is the price. Starting from £219, it is one of the cheapest, yet still delivers just as well as the mini 3.

The iPad mini 4 took quite a change. It is considerably lighter at a weight of 299g with the same sized screen. It has an upgraded A8 processor, colour-rich retina display, better cameras and it supports split-screen apps. The use of the Touch ID and the full laminated display has the upper hand upon the mini 2.

This iPad mini 4 is priced at approximately £319.


There are more Android tablets around now, due to Google’s Android OS making it inviting for many manufacturers to make an Android tablet. Android tablets have really been enhanced and improved. Android is popular due to its price and you have over 1.3 million apps in the Google play App store. Google’s Android has ‘Google’ voice integrated in, so you can speak to your tablet, and receive help.

Samsung Galaxy Tab S2

The Samsung Galaxy Tab S2 has an 8 inch screen, is only 5.6mm thick and weighs 265g. Just like the iPad, it has a Touch ID. With the Samsung Galaxy Tab S2 you have to capability to insert a microSD card slot on the frame and this can boost the 32GB to 64GB.

As a bonus with this tablet, you get “Microsoft Office and 100GB of OneDrive free for two years.”

The price for the Samsung Galaxy Tab S2 is approximately £319.

Google Nexus 9

The Google Nexus 9 is an Android tablet designed by HTC. It has an 8.9in screen, weighs 425g and is protected with gorilla glass. There are front-facing “BoomSound” speakers which enables the music and audio to be richer. Due to the 64-bit processor, it is easy to watch videos, check email and tweak documents.

The Nexus 9 has Android 5.0 Lollipop, which is a version of Android OS developed by Google. The Benefit of Android Lollipop is that a refreshed notification system has been introduced, and battery consumption has been improved.

The price for this is approximately £189.99.

Wireless System

Something to think about before ordering 30 tablets to be used in a single classroom would be your current Wireless System. When was it installed? What is the speed like when browsing the internet or streaming a YouTube video? If you think the speed is slow when you’re the only one using the wireless, how do think your 30 pupils all trying to access online content at the same time are going to find it? Chances are, if your wireless system was installed more than 3 years ago, it’s going to struggle with the demands of a modern day classroom.

Luckily, this is where Coretek can come in to save the day. We can carry out a survey of your current wireless system, which will provide an in depth report evaluating your system as it stands and showcase our recommendations for a new Dell SonicWALL system.

The approximate price of a Dell SonicWALL 802.11AC Wireless System with 10 Access Points is £6000.

So these are a few of our chosen tablets that we feel are best for use within Education. They all supply a wide range of apps that will cater for any lesson, but each tablet is completely different to the next. There are the Windows tablets that are great for the use of attaching a keyboard to the screen, therefore transforming it into a laptop alternative. Apple tablets have the most extensive app store, having something for your every single need, and they are very lightweight. Then lastly, the Android tablets are very reasonably priced and there are a whole variety of Android tablets.
