The cellular transmission SAR values for the Samsung Galaxy A42 5G (FCC ID A3LSMA426U) are 1.11 W/kg (watts per kilogram) at the head and 1.25 W/kg when worn on the body. The hotspot/Airplay SAR level is 1.06 W/kg. The simultaneous transmission SAR values for Galaxy A42 5G (cellular plus Wi-Fi) is 1.59 W/kg at the head, 1.55 W/kg when worn on the body, and 1.59 W/kg when used as a hotspot simultaneously with other transmitters active.

SAMSUNG GALAXY A42 5G Safety Tip: Turning Off Wi-Fi and Bluetooth Reduces Radiation.
This SAR chart reveals how turning off Wi-Fi and Bluetooth on your SAMSUNG GALAXY A42 5G can significantly reduce your exposure to radiation. Our SAR comparison chart shows that by simply turning off these transmitters, you can lower the RF radiation exposure to your head by 30.2%, and you can lower exposure to the body by 19.4%, when considering these differences between cellular-only (Wi-Fi/Bluetooth OFF) and simultaneous use exposure (Wi-Fi/Bluetooth ON), a wise way to reduce excessive phone radiation is to tap off unnecessary transmitters when not in use. Additionally, when using your phone as a hotspot, turning off Bluetooth can reduce your exposure by up to 50% according to the FCC SAR report for device number A3LSMA426U.

Key Takeaways
Children vs Adults: Children have higher SAR levels due to thinner skulls and developing tissues, making them more vulnerable to radiation.
Wi-Fi Impact: Simultaneous use of cellular and Wi-Fi transmission increases SAR levels for all age groups.
Precautionary Measures: Using radiation protection products like QuantaCase can help mitigate these risks, especially for younger users.
By understanding these differences, parents and guardians can make informed decisions to better protect their children from excessive microwave radiation exposure, emphasizing the need for safer smartphone usage practices and protective accessories like QuantaCase.
The Specific Absorption Rate (SAR) of a mobile device measures the amount of radio frequency energy absorbed by the body during device usage.
The SAR values for the galaxy-a42-5g (FCC ID A3LSMA426U) are as follows:
1.11 W/kg when held at the head with cellular transmission only
1.25 W/kg when worn on the body with cellular transmission only
1.06 W/kg when used as a Hotspot or Airplay
1.59 W/kg when held at the head with simultaneous cellular and Wi-Fi transmission
1.55 W/kg when worn on the body with simultaneous cellular and Wi-Fi transmission
1.59 when used as a Hotspot simultaneously with other transmitters active.
FeaturesPixel Density (PPI) is refers to the concentration of pixels on a particular display, measured in pixels per inch (ppi). Pixel density is calculated by dividing the diagonal pixel resolution of a display by its diagonal size, higher pixel density better display quality.

CPUCPU (Central Processing Unit) mostly known as processors, CPU processes instructions in order to carry out certain functions that make your device operate properly. Processors are often described as the brain of computers, smartphones and tablets, Smartphones and tablets rely on processors to carry out their every task, Processors are an incredibly important factor in selecting any type of computing device, including your smartphone.
GPUGPU (Graphics Processing Unit) is a single-chip processor designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display, This includes things such as lighting effects, object transformations, and 3D motion.

Card SlotMemory Card Slot is a special slot for inserting a memory card. Memory cards allow you to expand the phone's built-in memory, A memory card (sometimes called a flash memory card or a storage card) is a small storage medium used to store data such as text, pictures, audio, and video, for use on small, portable or remote computing devices such as mobile phones, mp3 players, digital cameras.

SensorsSensors are electronic components that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure and location, The output is generally a signal that is converted to use in computing systems, a location sensor, such as a GPS receiver is able to detect current location of your electronic device.
BluetoothBluetooth is a wireless communications technology for exchanging data between mobile phones, headsets, computers and other network devices over short distances without wires, Bluetooth technology was primarily designed to support simple wireless networking of personal consumer devices.
