Google Nexus 4 vs. Samsung Galaxy S III: Fan favorites

Connectivity

We usually don't specifically cover connectivity in this kind of comparison articles, but the two contenders here call for an exception.

Both phones have quad-band 2G connectivity and quad-band 3G connectivity with HSPA. The Nexus 4 supports DC-HSDPA, which doubles the download speeds if the carrier supports it.

It doesn't have LTE, at least not officially. You can enable it, but only one band is supported and (depending on your region) it might or might not be the right one. So, you shouldn't take LTE for granted when buying the Nexus 4 - most likely it won't work.

The I9300 Galaxy S III does not support LTE, though there's a dedicated I9305 version that does. It's tailored to support the networks in region where it is sold and if ultra-fast mobile data rates are your priority might just be worth the extra investment.

Local wireless connectivity is almost identical - dual-band Wi-Fi a/b/g/n, Bluetooth 4.0 and NFC are all supported. Both phones offer more advanced features too - DLNA, Android Beam (file transfer over NFC) and Miracast, a wireless TV-Out standard. Miracast requires a dongle that hooks up to the TV though newer TVs might have it built-in.

Both phones support HD TV-Out with the proper dongle.

The Samsung Galaxy S III also has USB On-The-Go support, which means you can connect various USB peripherals - mice, keyboards and USB storage. The Nexus 4 doesn't have OTG, it seems to be a hardware limitation (it worked on the Galaxy Nexus).

Both phones also do TV-out via the USB port, though they use different technologies. The Galaxy S III has an MHL-enabled USB, whereas the Nexus 4 uses a SlimPort USB.

Winner: Tie. The Galaxy S III has USB OTG, while the Nexus 4 has rudimentary LTE support. Other than that, the two phones are too similar to pick a definitive winner.

Audio quality

The two contenders are pretty evenly matched in terms of audio quality. They both have nicely clean output and equal volume levels.

When used with an active external amplifier, the Galaxy S III has a slight advantage, but you'd probably need to do lab tests to detect it. What's more important is that both are doing pretty great, with no weak points whatsoever.

Very little changes when you plug in a pair of headphones - the two smartphones still deliver great results and this time the Nexus 4 is even closer to the Galaxy S III.

Check out the numbers and see for yourselves.
