The first product of the "F" series, the Optimus F5 strikes the middle ground between the affordable "L" and the top-end "G" series. Not surprisingly, LG did not use the premium glass panel for the back of the Optimus F5 and instead throws in a removable, plastic back that sports reflective patterns. The overall finish of the Optimus F5 is decent, although the plastic back has notable flex. It is not particularly thin (9.3mm) or lightweight at 131.1g, but feels nice in the hands even though its slippery back can be a cause for concern.
Dominating the front of the Optimus F5 is a 4.3-inch IPS display with a resolution of 960 x 540 pixels. Other main highlights is the inclusion of a microSD slot (supports up to 32GB capacity cards) to augment the 8GB internal storage that bumps up the overall storage capacity up to 40GB . It also comes with a removable 2,150mAh capacity battery.
The Optimus F5 runs on Android 4.1.2 Jelly Bean and LG’s Optimus 3.0 user interface (UI). The Optimus 3.0 UI offers exclusive features such as zooming in recorded videos and the ability to run two apps simultaneously on the same screen via QSlide. This is the same set of features that was first incorporated on the top-end LG Optimus G as demoed in this video:-
If you've seen the video, you would quickly realize that QSlide is LG's answer to Samsung's Popup Play and Multiple Windows. You can run two apps simultaneously on the same screen. You could even set the transparency levels of the window to either bring it to prominence or not. For now, you can only choose two out of the five QSlide enabled apps. They are Videos, Internet, Memo, Calendar and Calculator.
Similar to S Memo on the Samsung Galaxy Note devices, LG also has its variant, QuickMemo. However, the absence of a stylus or pen input like the S Pen makes one truly appreciate the need for a stylus to be used in conjunction with such note taking apps.
Afraid that you may miss out on taking the perfect shot at the right moment? The Optimus F5 allows you to quickly snap five photos at once so that you can preview them shortly and decide which one(s) to keep.
