    I'm looking for a case that blocks radiation coming from the phone. I know, who knows if radiation is really harmful or not but I'd rather be safe than sorry.

    Such a case though got me thinking, with all the radiation boucning around in the phone, maybe it would cause the phone to malfunction?

    Anyone know of such a case?

    If you block the radiation, it won't work as a phone, and won't be able to use any data either, including WiFi. That radiation is the radio frequency the handset uses to communicate, so if you block that, you basically have a media player, as long as the media is on the SD card or internal memory.

    There is nothing to worry about.

    Well, sort of. The danger is really that it's directed at your head, not that it simply exists. There was a recent release of an iPhone 4 case that is supposed to reduce the radiation that actually is directed at your skull by quite a lot. It still allows the radiation to go out the back of the case and thus make calls etc.

    That's a pretty simplistic and misleading comment.

    Mobile phone radiation and health - Wikipedia, the free encyclopedia

    There is no irrevocably proven cause and effect link between using cell phones and cancer or other health issues. However, there have been a lot of studies that indicate not only do we not understand this issue fully, but it's pretty likely that there is at least a small link.

    Your comment indicates that it's somehow unreasonable to be concerned, and it is absolutely not.

    To the OP, if you are concerned, consider using either a wired headset, or a wireless Bluetooth headset. Bluetooth signals are not designed to carry as far and are accordingly much lower power than a cell phone signal with correspondingly lower radiation levels. Even the new iPhone case supposedly only cuts it by half. Use Bluetooth, be hands-free, and be happy.

    Typically in the device there is a metalic divider/partition between the cell antenna and the speaker/screen.

    The DX is no different. If you note the SAR levels for the DX are not drastically different than any other smartphone. 1.38-1.41 IIRC.

    If you just want to yes use BT as its yet again weaker signal strength. Or use a corded headset if you really want to get away from it.

    BTW don't hold the phone to your head with GPS, WIFI and BT and Talking on the phone to your head if you are that worried. (yes I have seen people do that). Meanwhile also don't stand next to a functioning Microwave oven.

    Otherwise yes I agree there are radiation concerns especially back in the days of the early phones. Digital transmissions and newer designs have fixed much of this. I mean if it really wasn't a concern, why the rush to lower the power output of the cell devices to 6mW?

    And why is it SAR levels of 3+ are not allowed to be sold? (or at least I have never seen one)

    I don't think this is a good comparison for a lot of reasons. Microwave ovens have shielding around the entirety of the oven because they are designed to contain their energy, whereas cell phones by nature MUST project their energy. There is very little leakage from properly functioning microwave ovens. Actually, requirements state that they are not allowed to leak more than 5 mW at 5cm distance from the oven (source). Microwaves also decrease significantly over distance and we are not pressing the microwave oven against the side of our heads.

    Add to that the fact that most people spend a whole lot more time on the phone than they do standing immediately in front of an actively cooking microwave, and it's just not even in the same ballpark.

    The tiny little metallic shield in between the radio and the screen is clearly ineffective for protection, which can be easily demonstrated by laying the phone down on a metal table. Still got signal? Yep. The microwaves are still hitting the side of your head when talking on the phone.

    I don't think it's worth getting panicked over, but I don't think it should be dismissed either. If I spent a lot of time on the phone, I would likely spend most of it on a BT headset because it seems to me like an easy precaution to protect against something that is not entirely understood yet.

    The ONLY time I put the phone up to my head to talk is when my Bluetooth headset is either charging or I've misplaced it. I use the headset for 99.9% of my calls, especially at work as I work with my hands or in my truck where my hands are better suited on the steering wheel.

    Your last paragraph is exactly what I was getting at. Meanwhile you can't take much of a joke can you. :p

    OH and yes I know microwaves are supposedly shielded. have you ever used your phone while being 1 foot away from a functioning one? Ever get some interference, echos, etc. However, like I was saying remember your phone is designed to project AWAY FROM your head, the antennas are beam steering (on the better phones).

    So whilst there is some, its not alot.

    I like this one! Thanks everyone for your replies. I have both a bluetooth headset (that I can't seem to get working) and a bluetooth speaker for the car. I don't want to fiddle with the headset, wired or wireless, so that's why I was thinking of the case. I came from a Touch Pro that had a lower SAR rating so the x had me a little concerned but not enough to not get it.

    I never thought about not using the phone when you have GPS, wifi and other things active. that makes sense.

    I find the speaker phone works exceptionally well on the DX. On most phones when you put someone on speaker the other person usually asks, "do you have me on speaker phone"? But I put people on speaker phone on my X all the time and nobody's ever asked me if I had them on speaker. I don't know if it has to do with the 3 mics or what, but it seems to work rather well.

    Same here, I do it a lot simply because I don't want to hold the thing up to my head that long. speakerphone works really well when placed on a hard surface.

    You do realize phones today have their antennas at your jawline, where a bluetooth headset places a microwave emitter right at your ear canal.

    So, if you keep your phone in your pocket you've got the bluetooth sending energy right into your head, and your phone sending energy right into your nads. If you're a guy that is. ;)

    Hey ladius! I'm new to the forum and Androids in general, but I had one for my iPhone that was supposed to redirect the signal/radiation away from your head and thus did not reduce the signal at all, but spared you a lot of radiation exposure.

    What kind of phone are you using?

    Just saw how old this thread is! Not sure if anyone will see this. but in case that anyone is still looking for some radiation blockage I found a few via Amazon for Motorola and Galaxy (no S5 ones though). I believe they work well and they're quality cases in general.

    GALAXY S Nexus - Amazon.com: The Pong Case for Samsung GALAXY S Nexus - For Verizon and Sprint, Soft Touch Black: Cell Phones & Accessories

    GALAXY S4 - Amazon.com: The Pong Case for Samsung Galaxy S4, Charcoal Black with Gold Reveal -Verizon: Cell Phones & Accessories

    GALAXY S3 - Amazon.com: Pong Rugged Case for Samsung Galaxy S3 - For Verizon, Black with Gold Reveal: Cell Phones & Accessories

    MOTOROLA DROID X/X2 - http://tinyurl.com/okcqr7u


    I'll keep digging for a place to get one for the S5!

    And I agree. Using speaker works very well while the on a call. I try to keep the phone out of my pocket and away from me when I can, but I have some more peace of mind using one of these cases

    Welcome to the forums! :D Precautions are always great, but in this instance there really is nothing to worry about:
