Performance
The LG K4 is equipped with different chipsets depending on the model. The K120E and K130E variants use the Mediatek MT6735M chipset, while the K121 features the Qualcomm MSM8909 Snapdragon 210. The quad-core processors—1.0 GHz Cortex-A53 for the Mediatek models and 1.1 GHz Cortex-A7 for the Qualcomm model—are basic but can handle routine tasks without significant lag. The GPU varies as well, with Mali-T720MP2 for the Mediatek models and Adreno 304 for the Qualcomm variant. These are not suited for demanding games or applications but can manage casual gaming and multimedia playback effectively.
