YouTube has a dark mode. Here's how to turn it on...
Paint it black.
Google is rolling out a dark mode to its YouTube mobile apps. Last year, it added the previously hidden ability to change YouTube's background from white to black to YouTube on desktops and laptops. Dark mode is available now for iOS and is now rolling out to Android devices, XDA Developers reports. 
Here's how to enable it on iOS:
Launch the YouTube app and tap your account icon in the top-right corner. 
Tap Settings. 
Tap to toggle on Dark theme.

The process is similar for desktops and laptops: Click your account icon in the top-right, click the Dark theme line directly above Settings and then click the toggle switch to turn on Dark theme.
For Android, you will find the Dark theme toggle switch by going to Settings > General. If you don't see it there, check you have the latest update from the Play Store, then try closing and opening the app a few times, as Redditors suggest here. That worked for (at least some of) us.
For both mobile apps and desktop site, YouTube remembers your light or dark preference for future visits.

Three has just announced it has begun to roll out its 4G Super-Voice technology in the UK making it easier for customers to make calls, send texts or go online in places that had previously had poor or no signal reception at all. While Three is calling the technology 4GSuper-Voice, US readers may be more familiar with it under the VoLTE moniker.
Three’s 4G Super-Voice already covers most of Edinburgh, Birmingham, Exeter and most of London, with the continued rollout of the low frequency 800MHz signal allowing for improved indoor coverage, fewer blackspots and better quality call connections.
The technology is busy rolling out in Manchester, Liverpool, Cardiff and Bristol, with the aim of covering 65% of the UK by the end of 2015. By 2017, Three hope that upto 5.5 million customers will have access to the 4G Super-Voice technology.
Full Press Release: 
Three UK tackles indoor blackspots with latest network enhancement in the latest enhancements to its network, Three is introducing a new technology, named 4G Super-Voice. 
*.One million customers to benefit from increased indoor and rural coverage by end of year 
*.Up to 5.5 million customers with access to 4G Super-Voice by 2017 
*.Three UK first UK operator to launch VoLTE – (4G Super-Voice)In the latest enhancement to its network, Three is introducing a new technology, named 4G Super-Voice.
Based on a roll-out of low frequency 800 MHz spectrum it allows a mobile signal to travel much further into buildings and extends its reach to more rural areas, removing many of the current coverage ‘blackspots’ across the country. Customers will be able to make calls, send texts and get online in places that previously had poor or no signal.
4G Super-Voice is made possible by the addition of the low frequency spectrum to the Three network, that will enable its 4G network to carry voice calls using VoLTE technology as well as texts and data. Three is the first UK operator to launch VoLTE technology.
The combination of both lower and the higher frequency spectrum (1800MHz) which Three currently uses means customers will benefit from the advantages of each, meaning improved indoor coverage, less blackspots and better call connections.
The enhancement is the latest initiative in our drive to improve indoor coverage which includes adding new sites to the network and launching our WiFi calling application, Three InTouch, last year.4G Super-Voice already covers 50% of the UK population for indoor coverage and more than three quarters of London, Edinburgh, Exeter and Birmingham.
 This is combined with our 3G network which already offers 98% outdoor UK population coverage.Three has also begun rolling out the technology in many other towns and cities across the country including Cardiff, Manchester, Liverpool and Bristol.
By the end of the year it will extend to 65% nationwide, meaning millions of our customers will soon benefit from improved coverage indoors, in rural areas, and on public transport.
By 2017, we expect up to 5.5 million Three customers could have access to 4G Super Voice, subject to device compatibility and take up.  Director of customer strategy, Danny Dixon, said: “Not being able to use your phone as and when you want, no matter where you are,is one of the biggest pain points for customers. 
Today’s announcement is the latest step in our efforts to offer customers a quality experience on what is already the UK’s most reliable network.”  Bryn Jones, chief technology officer at Three, added: “By the end of the year, one million of our customers will have access to better indoor coverage and be able to use their phones in more places than ever before. 
We are proud to be the first network to roll this out across the country.”Customers require a compatible handset to access the new technology which will be available on the Samsung Galaxy S5 at launch. New devices will be added regularly including recent iPhone models later this year.
The customer simply needs to update the software on their compatible device to the latest version to access 4G Super-Voice completely free of charge. When the update is ready for a customer’s handset an alert will be sent, notifying them to update their operating system, by following the on-screen instructions.
