Design and Build
The LG KU2100 is encased in a compact body with dimensions of 109.8 x 53.4 x 12.9 mm and weighs 121 grams, allowing it to fit comfortably in the hand. The physical design reflects the mobile trends of the early 2010s, with a straightforward mini-SIM slot supporting GSM and HSPA network technologies. Its sleek black finish imparts a classic look, although the screen-to-body ratio of approximately 43.7% reveals a significant bezel presence, characteristic of that period.
