Androids have electromagnetic sensors? Wha? - Epic 4G Q&A, Help & Troubleshooting

Why do our androids have electromagnetic sensors? I didn't even know of such a thing. I had recently stumble across an app and it really proves this is true.

I own several magnets to electric magnets also which I used to test this app. But anyway.. why do androids have this "sensor" in the first place?

Light leakage at bottom of screen

Anyone notice any light leakage on the very bottom of the screen? If I look close in a dark room when my four capactive buttons are lit I have a little light leakage. Mine is below the home button. This reminds me of the evo.

None here.

How can you have light leakage when the screen doesn't have a backlight?
It's worse than my evo :0

Let me make this perfectly clear. Abusive and derogatory posts are not welcome at XDA. Any thought otherwise will be met with infractions and/or vacations from XDA. This abuse is despicable.

Traded! Thanks for being here XDA!

I have a Motorola Photon 4g. Excellent Condition! Screen is PERFECT and has been in a case from day 1! Who wants to trade? I'm already looking on craigslist to find someone local but am getting impatient. In North Indiana.
I have the orig box, charger and like I said, comes with the grey and fake leather case that I bought from Sprint. I bought it straight from a corp. store.

NOTE: I'm only interested in trading the Photon and some Cash for an Epic Touch at this point.
wishful trading but most people are completely in love with their epic touch 4g, and you may have better luck putting this in the market section
Thanks! I did so we'll see.

I'm getting tire of this POS searching for signal in my home.
Thanks for letting me know!

Well if anyone wants the trade, someone better make the first offer. I have someone emailing me from the post I have up on craigslist just interested in trading the Photon for their Epic Touch, they don't want the touchpad.
Anyone want to trade?

How is the signal on the photon? I'm wondering because my wife and I use these phones for our work and in low coverage areas, so it might be smart for us to have 2 different phones just for diagnostic sake.
Sent from my SPH-D710 using xda premium
I've never dropped a call. People all say on the forums that the photon has one of the best radios they've ever used. I'm just bored with the phone, that's why I want the epic touch. I have zero complaints about this phone as far as call quality, and reception is concerned. I just want something thinner.

Well, according to the photon forums, it appears to be mod friendly as well which is primarily what I care about, and the touchpad would actually be highly useful for my business, so I'd do the trade.
My S2 has what amounts to some light rubbing on that bottom piece of shiny plastic... You have to look at it in the light at an angle to even see it. It had the anti glare screen protector put on in store upon removal from the box, and both it and the screen are flawless.
I can get some pics if you're interested.
Sent from my SPH-D710 using xda premium
I tried to include some pics of the photons light rubbing as well. Due to it being in the case since purchase, it has gotten a few scuffs on the sides. I'm assuming like yours, something you need to look for to see. You don't happen to live around Fort Wayne, IN do you? Also, the TP is a 32gb with the touchstone dock and i have an old iPad 1 case that it fits in and has 2 stands built into the case that work really nice. Tho after thinking about it last night, it's not exactly a fair trade so I was thinking either I'd trade my Photon and some cash for the Epic Touch or both my Photon and TouchPad for the Epic Touch and some cash. What do you think?

Doh, oh well. I don't get paid again for a week and trading the S2 for just the photon (cash doesn't sweeten it much, still left without the S2 in the end) doesn't work, was much more the touchpad I'd be interested in.
I can understand where you're coming from though, so good luck!
Sent from my SPH-D710 using xda premium
Well I'm still open to the idea. If you really want to trade, I don't care when you get paid... we work out a deal and swap phones ASAP... we can just work the TP deal when you get paid. It's up to you. I just think if I trade the TP and my phone for an ET, I'm getting screwed.
How much are you thinking in addition for the Touchpad?
Sent from my SPH-D710 using xda premium
IDK... $100. I think that'd be fair. The 16gb Touchpad is $99... the 32, $150. After tax, shipping, the case, and touchstone charger, I spent around $225. What do you think?

E-Cigarette Works as a Stylus

Hey guys, random thing I just discovered while holding too many gadgets at once and trying to smoke simultaneously. As you know, random objects (pencil, pen, popsicles.....) do not work on phone\tablet screens since capacitive screens use dielectric conductivity between the screen and skin. However, the electric cigarettes you see everyone using nowadays, do in fact work quite well. The bottom part of them, where the battery casing is, for clarification. Anyhow, never seen this mentioned anywhere and figured this is the spot for it.
Tested with an eGo SOV model, but I imagine the concept is universally applicable.
Yup eGo twist works

Attention!!! I have found a fix for signal problems!!!

DISCLAIMER I AM NOT RESPONSIBLE IF YOU RUIN YOUR PHONE. THIS WILL VOID YOU WARRANTY UNLESS YOU FOLLOW MY INSTRUCTIONS. I CANNON GUARANTEE THAT THIS WILL WORK FOR YOU. I'M JUST SHARING THE INFORMATION
OK so as you have probably read in the title. I have found a fix for signal problems on the E4GT! All you have to do is take the back door off the phone. No do you see those stickers on the back. Those are covering up the antennas peel those stickers off DON'T throw them away stick them to something so that you could reuse them and stick them back on the phone for issues if you have to take it to the Sprint store. I have mine stuck to the back of the back door mine still fits on bcuz I have the extended battery.
After you have peeled those off you should notice that you're already getting a bit better signal. You should get a lot faster GPS lock that's what I noticed and it stayed locked on.
Now the next thing you can do is your choice. What I did was get a piece of tinfoil and folded it a couple of times and then cut a place for the camera I'll provide a pic of what mine looks like.
Now stick that piece of tinfoil on there and snap the back of the phone back on and you should be good to go.
Ever since I did that it worked miracles. I no longer have that big of an issue with signal on this phone.
Sent from my SPH-D710 using xda premium
Genius. So you are saying pull off the protective elements of the antennas then short them all together with tinfoil!? For any other people reading you can destroy your antenna this way. They are fine tuned to pick up certain frequencies. Please do not do this. Putting tinfoil will not help. The same thing goes for those stickers you put under your battery. Placebo effect. Op while your at it try sticking a wire into those ports on the back of the phone. Im sure it wouldnt hurt. DISCLAIMER-STICKING ANYTHING IN THOSR PORTS WILL LIKELY SEVER THE CONNECTION FOR WHATEVER THAT PORT WAS GOING TO. ITS HAPPENED BEFORE. ALREADY TESTED DONT DO IT.
sent from my Provari with a mini rda!
Its not actually shorting them. They are protected ribbon antennas. What the foil more than likely does is direct the signal in a way. It may help direct the signal either to the phone or away. Either way, this is still not advisable to do. There are exposed components like antenna interfaces that could be damaged.

Gray are they protected when you peel off the black cover like he suggested? I havent had a need to pull that off. So I dont know if its bare under there or not.

Yep. They are like flex cables.

So does this actually work or not? I'm not gonna chance severing network connections with tinfoil if it doesn't lol
Sent from my SPH-D710 using xda app-developers app
It works just fine for me it will only sever the antennas if you take the back off a lot I've noticed a boost of about 3 bars
Sent from my SPH-D710 using xda premium
Oh and if it doesn't work you can replace the housing on the phone cuz that has the antennas in it. The parts are on eBay for like $12-$15
Sent from my SPH-D710 using xda premium
The housing is not a concern. It is the exposed antenna interfaces on the motherboard. If those get shorted in any way, you will never have a signal again.

These do not work, there's many webpages to see this info. They've been sold for years and years and none of them work.
The antenna built into a mobile phone is very carefully designed for optimal reception/transmission and small piece of plastic with gold etch on it won't help, it's more likely to cause issues.

The antennas on the Moto G appear to be bonded onto the back, top and bottom - remove the back cover and you can see a slight raised section on the top and on the bottom edges of the phone.
Seriously, these stickers only work when you stick them to your forehead so everyone you meet can save time finding out what an idiot you are.
