LG G4: Be careful while fingering this leather-clad smartie pants

Removable battery, micro SD expansion? Walk this way...

Smart goals

The Quad HD 1440x2560 display has been improved, delivering deeper colours. The blacks are eye-poppingly black – the kind of black black you expect from AMOLEDs, but on an IPS panel. The outdoor legibility has also been improved, I thought.

All the smarts...

The UI (UX 4.0) has also made tasteful incremental improvements over last year’s, blending the stark austerity of Lollipop with LG’s rather busy notifications quite well. And there are thoughtful additions. “Smart Actions” is a little like Motorola’s er, “Smart Actions” – settings change based on location, time or whether a connection is active – but more limited in scope.

The default set is merely things that happen “at home”. By default you don’t get a notification to remind you the settings has changed. I found it impossible to tell the phone that it was in my home location. So the feature went untested, although this was a pre-production model, so I presume this will have been ironed out on retail units.

...but some Smart features work better than others

Swipe right at the home screen and you get LG's portmanteau app in the same place HTC puts its HTC Sense web2.0rrhea app. I found this one to be more useful than I expected – it includes sub-panels covering calendar, settings, the IR remote QRemote, and LG Health and help. You can turn any or all of these off. The two most attractive UX features – knock to wake, and the not-exactly-secure knock to unlock – debuted in the G3.


The camera was top notch. A wide (f1.8) aperture and LG’s laser rangefinder give colour-blasted images with plenty of detail, and near-instant shot-to-shot time. The exposure balance is excellent and performance in low light is more than impressive.

Optical image stabilisation is included, and 4K shooting and Raw (DNG format) images are also supported. I really wouldn’t want to call it between the cameras on the Samsung, Apple and LG flagships without substantially more testing. With the exception of HTC, it’s a vintage year.

The LG came out slightly – not massively – ahead on battery performance. Last year’s G3 was the first mainstream flagship with a power-guzzling Quad HD display, and despite packing a larger battery than rivalsthe display demands took their toll. I’d say the G4 is average. LG dodged the bullet by opting for the slightly slower Qualcomm Snapdragon 808, rather than the faster but thirstier 810.

Samsung's own chipset in the S6 wins out on those rare occasions you need raw speed, but in long-term use I've found the S6’s power consumption is appalling unless you turn on the power saver. Neither comes out well next to the iPhone 6 Plus, and in Android land Sony reigns supreme for battery life. Largely because it's much more aggressive about turning down background tasks by default.

    It's coming. Microsoft is preparing to start shoveling the latest version of Windows 10 down the throats of refuseniks still clinging to older incarnations.

    The Windows Update team gave the heads-up through its Twitter orifice last week. Windows 10 2004 was already on its last gasp, have had support terminated in December. 20H2, on the other hand, should be good to go until May this year.

  • Throw away your Ethernet cables* because MediaTek says Wi-Fi 7 will replace them

    *Don't do this

    MediaTek claims to have given the world's first live demo of Wi-Fi 7, and said that the upcoming wireless technology will be able to challenge wired Ethernet for high-bandwidth applications, once available.

    The fabless Taiwanese chip firm said it is currently showcasing two Wi-Fi 7 demos to key customers and industry collaborators, in order to demonstrate the technology's super-fast speeds and low latency transmission.

    Based on the IEEE 802.11be standard, the draft version of which was published last year, Wi-Fi 7 is expected to provide speeds several times faster than Wi-Fi 6 kit, offering connections of at least 30Gbps and possibly up to 40Gbps.

  • Windows box won't boot? SystemRescue 9 may help

    An ISO image you can burn or drop onto a USB key

    The latest version of an old friend of the jobbing support bod has delivered a new kernel to help with fixing Microsoft's finest.

    It used to be called the System Rescue CD, but who uses CDs any more? Enter SystemRescue, an ISO image that you can burn, or just drop onto your Ventoy USB key, and which may help you to fix a borked Windows box. Or a borked Linux box, come to that.

    SystemRescue 9 includes Linux kernel 5.15 and a minimal Xfce 4.16 desktop (which isn't loaded by default). There is a modest selection of GUI tools: Firefox, VNC and RDP clients and servers, and various connectivity tools – SSH, FTP, IRC. There's also some security-related stuff such as Yubikey setup, KeePass, token management, and so on. The main course is a bunch of the usual Linux tools for partitioning, formatting, copying, and imaging disks. You can check SMART status, mount LVM volumes, rsync files, and other handy stuff.
