The Optimus as a phone

These days, even entry-level smartphones get all of the connectivity they need to keep you in contact with the outside world. The Optimus has 3G, WiFi and Bluetooth, although we found the second of these a little tricky though. There were no problems to report with 3G.
During calls, the handset performs as it should: you can easily recognize the other party, and apart from a quiet background whistle, there was no distortion. There is however a small problem with the way the software works. You have to find an icon onscreen to bring up the numeric keypad to dial a number. It would have been much easier if you could make a call straight away as soon as you pressed the physical 'call' button.
As with all Android phones, the Optimus has great integration with all of Google's services, including, of course, Gmail. LG's push service should in theory mean that you get your e-mail at the same time as it arrives on the server, but in reality, we found that it sometimes took several minuts before showing up on the phone.

Until recently, LG hasn't been a particularly big player in the world of Android smartphones, but it has announced big plans for the year ahead, with several models running Google's mobile operating system in the pipeline.
After the popularity of the GW620 at the end of last year, the Optimus GT540 which runs Android 1.6 is designed as an accessible smartphone giving easy access to social networks. So: is the Korean manufacturer's second attempt at an Android handset, which has more than a passing resemblance to its Viewty Smart, any good?
The Optimus does remind us of the Viewty, and its combination of curves, a relatively slimline from and a reasonable weight (115 g) make it a pleasure to handle. The whole thing is made of plastic, but the brushed aluminium effect looks great. At first sight, the Optimus looks like it might seduce plenty of users ...

The back has an attractive brushed aluminium style finish
But after using it for a couple of weeks, we changed our minds because the screen didn't manage to stand up to spending a while in the bottom of a large bag. It was covered in scratches but the rest of the case was still in perfect condition. We dread to think what it will look like in a month's time ...

Ouch!
While we're on the subject of the 320 x 480 pixel touchscreen, LG has once again used resistive technology and it's quite frankly mediocre. We've seen both more reactive and more accurate screens elsewhere, which is a big problem when your phone has an all-touchscreen interface. The colours and contrast really couldn't be worse. There's no point even trying to look at it if there's lots of natural light, as you won't see anything. The majority of smartphone screens—apart from a few notable exceptions from HTC, Samsung and BlackBerry—are hard to use in bright sunlight, but the Optimus is the perfect example of how not to do it.

The resistive touchscreen makes you tap each letter carefully with a fingernail,
making the onscreen keyboard hard to use.
Using it: the Optimus doesn't go the extra mile
The interface is only very slightly different to the default Android look and feel. It's nothing like the practical, visually attractive software layer that HTC, amongst others, has developed for its Android phones. Navigating through the menus is easy enough and you can even use several handy shortcuts, but we've seen better all-round solutions on other phones. At the end of the day, though, for an entry-level phone, it's not too bad.
Responsiveness varies according to what you're trying to do, and overall it's easily done, but you have to make do with some slow downs here and there.
Multimedia is a strong point

With a 3 Megapixel camera, the Optimus isn't quite at the top of the table for cameraphones. What we can say is that to grab a few shots here and there that will end up as MMS or on a social networking site, it's a decent enough pocket-sized solution. You'll have to make sure that there's enough ambient light, of course. The options are as we've come to expect by now for this phone—minimal.

On the subject of media features, the Optimus can play DivX files, has an FM radio and decent quality audio. For browsing the web, you'll be able to do a little occasional surfing, but not with anywhere near as much ease as on a HTC Desire or Legend or an iPhone.
Finally, the Optimus has a battery life of a day and a half.
Pluses
-
Stylish
-
Interface with seven homescreens
-
Decent photos for an entry-level phone
-
Supports DivX video/FM radio
Minuses
-
Push e-mail is slow
-
Resistive touchscreen has poor brightness and contrast
-
High SAR index
-
Onscreen keyboard is slow and inaccurate
-
Camera has no flash
For an entry-level smartphone, the Optimus GT540 is not at all bad at multimedia. It's a shame the resistive screen is so poor, because its lack of brightness makes writing texts and e-mails hard. If you're a fan of writing to friends on your phone, look elsewhere.
