TechNow: LG G3 cases go on sale, reveal curious back design 24 April, 2014

Alleged cases for the upcoming LG G3 have surfaced and are currently on sale at wholesale retailer Aliexpress.

The holes on the cases give us a pretty good idea of the phone's port and button layouts. LG will be keeping its rear-mounted Power/Lock and volume rocker keys with the rumored 13MP camera on top. Interestingly, there are two adjacent square cut holes on its left and right sides. Almost certainly one of them is going to be for the LED flash, while the other could be for either a secondary LED flash or some kind of a sensor (heart rate monitor or a fingerprint scanner are some options that sprint to mind). The main speaker is below the rear-mounted controls.

At the bottom left of the cases, there's room for the antenna of the DMB-H-equipped Korean version of the phone, the 3.5mm jack is at the bottom next to the microUSB port. What seems to be a cut hole for an IR blaster is at the top, while the left and right sides are bare of any controls.

The leaked image of the LG isai FL

Recent rumors claim the LG G3 is going to be based on the recently leaked Japanese LG isai FL. The Japan-only smartphone sports a quad-core Snapdragon 801 SoC, clocked at 2.5GHz, a 5.5-inch LCD rumored to have 2560x1440 resolution, 2GB RAM, 32GB internal memory with microSD support, 3000mAh battery, and an IPX7 rating, which means it is water resistant.

The LG G3 puzzle is slowly but surely coming together, as earlier in the week we received screenshots taken from the phone. They're from the brand new Optimus UI running on top of Android 4.4.2 KitKat and shows the new design direction in which the company is taking its user interface.
