Just when we thought LG was done with its Optimus L-series for the year, the Korean company surprised us with the LG Optimus L9, which replaces the Optimus L7 at the low-end range. The L-series devices are positioned as LG's stylish yet affordable line of entry- to mid-level phones, so they definitely don't compare to the company's quad-core offerings like the 4X HD or the Optimus G. Instead, the L9 runs Android 4.0 and boasts a 4.5-inch qHD display along with a dual-core 1 GHz TI OMAP 4430 processor and 5-megapixel camera. At $79.99 with a two-year contract on T-Mobile, it's designed to appeal to shoppers on a budget. But is it a good buy? Let's find out.
