LG Quantum Optimus 7Q Preview


Unlike its famous cousin – the LG Optimus 7, the LG Quantum or the LG Optimus 7Q hasn’t been in the limelight much before its release. Not many details about it were leaked, but we did know that LG was going to launch a QWERTY slider smartphone running Windows Phone 7.

On October 11, Microsoft officially unveiled the LG Quantum (Optimus 7Q) along with 8 other phones. Most of the phones share similar hardware specs, and the LG Quantum Optimus 7Q is no exception. It has a pretty standard touchscreen slider form factor and a stylish design. It sports a nice QWERTY keyboard and a 5 MP camera.

The LG Quantum has a standard horizontal slider form factor, nothing new about it. The design is more functional than stylish but the phone looks quite good. It has a 3.5 inch TFT capacitive touchscreen display with a resolution of 480 x 800 pixels, the standard display resolution for Windows Phone 7.

Below the display are the Back and Search keys and a Windows key. The horizontal QWERTY keyboard slides out from below the display. The keys are nicely spaced out and the keyboard is very usable. The LG Quantum (Optimus 7Q) is a bit bulky with dimensions of 119.5 x 59.5 x 15.2 mm and it also weighs a bit high at 176 gms.

User Interface

The LG Quantum runs the new Windows Phone 7 OS which was launched recently. It has a new UI and is very different from iOS or Android. It’s a very promising OS, but only time will tell whether it can compete with Android or iOS. It will have about 2,000 apps and games available at launch at the WP7 Mobile Marketplace.

It is powered by some powerful hardware which is common across the spectrum of Windows Phone 7 devices. It has a 1 GHz Qualcomm Snapdragon processor and comes with 512 MB RAM. It offers 16 GB internal storage and doesn’t offer support for memory cards.


A 5 MP camera seems to be the new minimum, at least in Windows Phone 7 phones. The LG Quantum also has a 5 MP camera with an image capture resolution of 2592 x 1944 pixels. It comes with autofocus and LED flash. It can handle 720p video recording at 30 FPS.

It supports video playback for the following formats – 3GP, MP4, H.264 and WMV. On the audio side, it can play MP3, WMA, WAV and eAAC files. It also has a stereo FM radio with RDS built in.


The LG Quantum has all the standard connectivity options that any other smartphone has. It offers GPRS, EDGE, 3G HSDPA, Wi-Fi 802.11 b/g/n with DLNA and Bluetooth 2.1 with A2DP connectivity. You can also connect it to your PC using the microUSB cable. It also has a built in GPS transceiver with A-GPS.


The LG Quantum (Optimus 7Q) is a very good smartphone which is packed with features. It runs the new Windows Phone 7 OS which seems to be quite promising. It will be launched for $199 on AT&T’s network in the US.
