These days, smartphones have so much packed into them its a wonder that their innards don’t burst open. Some of the more common components crammed into smartphones are:
- Bluetooth chipset and antenna,
- Cameras (front and rear),
- Capacitive touchscreen,
- Cellular antennae (one for each frequency),
- Flash memory,
- GPS receiver,
- SIM card holder,
- Wi-Fi chipset and antenna.
In the case of the Samsung Galaxy S, that’s a lot of stuff to fit inside something roughly the size of an iPod Classic. So, when it comes to listening to FM radio on the SGS you might expect it to work out of the box without the need to connect anything else, right?
Well, not quite.
A lot of mobile phones won’t actually include an antenna for the FM radio inside and instead rely upon the wires inside your earphone cable to pick up the reception. This is also why when you try and run the FM radio application on the SGS without earphones connected it will refuse to start audio playback. However, there have been mobile phones with an internal FM antenna such as the Nokia 5030 and other feature phones. Having said that feature phones are less sophisticated and space challenged compared to smartphones.
Maybe with the way that electronics keeps shrinking FM radio might become more of a staple without connecting your earphones unless digital radio or streaming over he web becomes the mainstream.
