Samsung I9190 Galaxy S4 mini Audio and Communication

Audio and Communication

Sound quality through the loudspeaker was adequate, producing clear audio with voice levels recorded at 66dB, noise at 64dB, and ring at 75dB. The 3.5mm headphone jack ensured compatibility with traditional headsets, a feature cherished by many users. Communication features were robust: it supported a variety of network bands for both GSM and HSPA, with LTE support on some models. Wi-Fi connectivity, Bluetooth 4.0, and NFC (on select models) further enhanced its functionality. The inclusion of an infrared port enabled the device to be used as a remote control for televisions and other appliances.
