The cellular transmission SAR values for the Samsung Galaxy A12 (FCC ID A3LSMA125F) are 1.16 W/kg (watts per kilogram) at the head and 1.35 W/kg when worn on the body. The hotspot/Airplay SAR level is 0.92 W/kg. The simultaneous transmission SAR values for Galaxy A12 (cellular plus Wi-Fi) is 1.41 W/kg at the head, 1.49 W/kg when worn on the body, and 1.19 W/kg when used as a hotspot simultaneously with other transmitters active.

Samsung Galaxy A12 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 A12 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 17.7%, and you can lower exposure to the body by 9.4%, 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 29.3% according to the FCC SAR report for device number A3LSMA125F.

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-a12 (FCC ID A3LSMA125F) are as follows:
1.16 W/kg when held at the head with cellular transmission only
1.35 W/kg when worn on the body with cellular transmission only
0.92 W/kg when used as a Hotspot or Airplay
1.41 W/kg when held at the head with simultaneous cellular and Wi-Fi transmission
1.49 W/kg when worn on the body with simultaneous cellular and Wi-Fi transmission
1.19 when used as a Hotspot simultaneously with other transmitters active.
TypeDisplay Technology => A number of display technologies and types used in mobile phones => TFT (Thin Film Transistor), IPS (In-Place Switching), OLED (Organic Light Emitting Diode), AMOLED (Active-Matrix Organic Light-Emitting Diode), Super AMOLED (an even advanced version of AMOLED), Resistive Touchscreen (Resistive touchscreens contain two layer of conductive material with a very small gap between them which acts as a resistance), Capacitive Touchsceen (Capacitive touchscreen technology consists of a layer of glass coated with a transparent conductor)
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.

Camera
Main CameraCamera is able to capture photographs and usually videos, The most important characteristics of a camera are the resolution (measured in megapixels), lens focus type (fixed or automatic), higher megapixel cameras are known to capture higher quality photos, but not always a good measurement of the photos quality.
Selfie CameraFlash Light => There is commonly two types of flash lights are used in camera mobile phones, LED Flash (LED flash offers lower power consumption with drive circuitry that takes up very little room, LEDs can be strobed faster than any other light source), Xenon Flash (xenon flash produces an extremely intense full-spectrum white light for a very short duration)

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.
Wi-FiWi-Fi is a popular wireless networking technology using radio waves to provide high-speed network connections that allows devices to communicate without cords or cables, Wi-Fi is increasingly becoming the preferred mode of internet connectivity all over the world.
