My hilarious battery drain issue - Galaxy S III General

So, I found the source of my battery drain over the last few days!
At first, I suspected that I had a bad flash for the CM9, because it started happening about the time I got the nightlies installed. After a few wipes, the battery drain continued to no avail. "Android OS" was consistently ~70%+ of my total battery usage by the end of the day.
I work in an office, and my phone has been randomly making this beeping sound that I couldn't put my finger on. It did it constantly. Again, I just assumed it was a problem with the ROM or the flash, so I didn't complain-- I signed up for bugs like that.
Then, yesterday, my NFC tags arrived. After several hours of having a blast playing with them, I had in my head the small beeping sound it makes when the phone picks up a nearby field but doesn't know what to do with the information. I thought nothing of it.
Today, back at work, I set my phone on my wallet (like I always do) and hear the sound. It instantly dawned on me: one of my debit cards use NFC negotiation! (Visa PayPass) I confirmed it right away by taking out the card and tapping the back of the phone-- there was that all-too-familiar sound.
LOL. For days, my phone has been picking up the NFC field inside my wallet. I couldn't believe it.
I thought I would share . You also never know who else out there is having the same thing happening to them.

Ahaha, nice one there mate xD

I actually have a Faraday wallet (basically a normal wallet lined with tin foil). This will solve your problems. They're pretty cheap now, you can even make your own with duck tape and tin foil! I'd say its also a security must for anybody with nfc bank cards.

Are they really?
I have a faraday bag that i use for cell phone forensics and it looks to have clear finish in some places

Its effectivly a Faraday cage, after skimming took off people wanted to protect their cards, so they lined thier wallets with tin foil. Now professionally made ones are leather lined with cheaper as effective alloys.
I've made a duck tape one before, its easyto do (and cheap). I'll test its effectivness when I get home.
It can have holes of a certain size (smaller than the wave size).

nice...i have a somewaht similar issue with my wallet setting off metal detectors when i walk into stores. Wonder if it's related

They're ususlly not metal detectors, they're rfid scanners. A nfc card might intefere maybe if you're close enough?

Wait? they let you walk through the metal detectors with your wallet in your pocket? Most places require you to empty your pockets into a basket

I don't think he meant to say metal detector . He's talking about the RFID detectors that look for radio and/or magnet chips in stores.

i had a similar thing happen once for two months straight. Anti-theft strip from the harddrive packaging was stuck on the bottom side of the laptop sleeve in my bag and it was triggering the anti-theft alarm going in and out. I didn't notice it until i replaced the bag with another

Pardon the production values but I cannot scan a nfc enabled card in it. All you need it a roll of duck tape and a roll of tin foil. Just google how to make a duck tape wallet, there are some nice ones out there. Instead of just sandwiching the duck tape to duck tape, sandwich a piece of tin foil in between the two pieces of duck tape.

Just messed up my screen. (w/pic)

I was putting on a screen protector and the water got to the screen now the lower part of the screen is very white. Still very readable. What do ya'll recommend I do?

Is the liquid damage indicator normal? If so, swap it out with your provider. If it indicates liquid damage then see if there's an out-of-warranty replacement option and cross your fingers.
You could try drying it out with rice or silica dessicant. It might take a few days. Got any picts?
Anyone know how many liquid damage stickers are on the device? I know the one by the battery is still white. What the hell do i say. I just woke up and it was damaged.
That happened on my G1 and someone told me to pull the battery and set it on top of the refrigerator over night.
I know it sounds weird but the next morning it was dry. Something about the warm dry air coming from behind the fridge.

Put it on anything that radiates heat, nothing extreme but something that is somewhat warm to the touch. Refrigerator works well, also a PC, DVD player left running, etc.
Leave the battery out for 24-48 hours and see if it dries up the moisture...
Dry heat will help but be careful in case there's something that produces humidity nearby. I wouldn't leave mine on an appliance in the kitchen. I'd opt for an actual desiccant like silica. If you have a new jacket or pair of shoes you can find a packet in there. It's a long shot but rice also works in a pinch.
If that fails I'd send it to the OEM and play stupid. I don't think there are other LDIs in the device but if there are, I don't believe your provider would charge you a replacement fee because you checked the only one that's accessible. Just check it out with the respected technical department you talk to before sending it on, or ask a retail rep if your provider has a store or kiosk at a nearby mall. Just say you normally keep it in your pocket or in a protective case and boom, screen got messed up.
Same thing happened to mine, def the computer or fridge is a great way to get rid of the water. But only dry heat!

Yeah, it doesn't seem that huge problem, just give it some time and warmth
Some people have heated the (electric) oven up to 40-50°C and put the phone there, but I would recommend that only if any other method doesn't help..
Dry rice or silica dessicant. Take out the battery and stick it in there for a few days and it will be good as new.
Don't heat it, it won't work any better than this method.
Well I let it dry on top if my cable box and I happy to report all but four very very little dots dried up. I've learned my lesson and will only be doing dry installs for now on.

Some of these clear body shields are wet-applicant. They come with a little thing of liquid adhesive that you apply first. I've been around phones long enough to know that they don't play well with water, so I've steered clear, but I know plenty of people who don't have issues with them.
For the record, every wet-applicant protection system I've ever seen explicitly states that you should only apply it with the battery out and leave it out to dry for ~48 hours (to prevent exactly this).
Yes but this is my only phone and there's no way I can not use the phone for that long.

Haha, very creative. I wouldn't even think to use a cable box as the heat source even though I've been running one of those laptop cooling fan bases upside down on top of mine to vent the heat that was killing hard drives.

When messing around with phones to the degree that most of us do, it's always a good idea to keep a cheapo backup around.

I would highly recommend picking up a cheap backup - you never know when you'll need it. Typically you can just snag the cheapest prepaid phone that T-Mobile offers, they usually have something for $20 or less. Toss the SIM it comes with and just keep it around for an extra. That way, if something were to happen with your main phone, you've got *something* to keep you going until you can figure out a replacement.

yeah, and if this is not your first T-mobile phone, you can just go back to the old phone for a day or two while you wait.
Mine had the same thing from a paper cup leak onto the table my G2 was sitting on. It didn't resolve with the rice/heat tricks but T-mo switched it out under warranty. No down time because they ship the replacement and you send the defective one back in the same box.
Get closet dehumidifier. It's at Walgreens in the hardware section. It comes in a plastic tub and you put it in your closet to remove moisture from your clothes. They're little white beads in a basket with a cup underneath to catch the moisture. Put your phone in an enclosed space with that.
If the water was clean it should leave no residue. If it was soapy then you will probably have marks left over afterwards

Conductive tape for better WiFi/GPS?

Someone on the inspire forum used conductive tape on top of their antennas to boost signal dramatically! Anyone know the insides of a500 know if doing this would help us cuz wifi sucks..?
Sent from my Inspire 4G using Tapatalk
Funny, I am going to be making some conductive glue in the next day or so. I was wondering what I should do with the leftover. I will consider putting some on the antenna just for kicks. maybe I can coat some paper and extend it a bit. If anyone has a good idea of how to implement it I might give it a shot. I'm certainly not a radio engineer type person, so I really don't know if there are any guidelines that I should follow. Like whether or not this will need direct contact with the core wire, recommended length/shape to match frequency, what matters, what doesn't, would a graphite conductor even work, etc. Keep in mind that the resistance will increase with length on this adhesive. I can double coat it and help some but there is no way to avoid this without embedding a wire. I already get a good signal but there's always room for improvement. And I need to open my case to fix a dented corner. Lucky I didn't break the glass when I dropped it on the pavement...
And if anyone believes that this is a bad/goofy idea please say so. I'd rather know not to try something and why than to waste the time.
I was thinking that you could use small strips of aluminum tape (the kind that is used to seal furnace duct joints)
It is very sticky and you would have to use some Goo Gone on a Q-Tip to remove the adhesive from a small strip where the antenna contacts the tape.
I am going to try this once my plastic opening tool kit arrives from China.

I thought you sold your 500?
Considering the 500 uses the same hardware manufacturer for the antenna, I can say I get good Wifi in my flat. Even in the toilet.
GPS though, I need to be within 3 meters of a window, but that's understandable.

[Guide] How to prevent scratches to your back cover

Ok so this is what I have been doing to my phones for a while now to stop scratches. Even a case can cause minor scratches/scuffs after time.
I'll get pics of the process later this evening(didn't think about it last night)
Just to note this is COMPLETELY reversbile is you do not like it(see below for removal info)
1) Head to your local Home Depot store.
2) Pick up a SPRAY can of a product called PlastiDip (located in the paint isle) - I recommend the black color
3) Next, take some newspaper (or anything to help catch overspray) and lay out on the ground/table (I recommend you do this outside or a WELL ventilated area)
4) Now remove the battery cover from your phone and lay down Logo side up.
5) Shake up your PlastiDip can very well(per instructions on can) and spray an area AWAY from your cover to get an idea of the spray pattern.
6) Now, cover the back cover in stages. Do a light coat of PlastiDip, then give it a few min, then another layer, then a third layer(each layer should be a light coat). Wait about 10-15 min after the 3rd coat and pick up the cover and inspect it to make sure you got all the corners/sides/top/bottom properly. If not, do another light coat(focusing on those areas you need to)
7) Now let it dry for ~30min - 1hour(at this point you can bring back inside)
8) Now put back on the phone and enjoy the new rugged rubberized back plate that will stand up to slight abuse(it can still peel is you manhandle it)
Now if you don't like it, just remove the back cover, and start at 1 corner and slowly peel the coating off. If is snaps, just lightly rub back with your finger to remove. Comes off clean and easy since it is just a spray rubber.
People have been using PlastiDip to cover all sorts of items, from tools, to car emblems, to even ENTIRE CARS!!!
Or u can buy an xtremeguard full body cover for like $3 or $4 and install just the back like I did.

And real tuners have been laughing for years at ricers like this! PlastiDip was meant for putting new grips on hand-tools, ricers have taken it to an entire new and awful level....
Paint > Rubber
you get what you pay for
if you really want protection on your phone, either put on a full body protector or just buy a new back cover, I bought a nice looking carbon fiber skinned one without any carrier branding on it for $15 shipped!
With plastidip you still fit in a case but it gets peeled off..
With clear coat only a few tpu cases fit.. Most cases are not going to fit unless ur rocking a bumper

It really is not that thick of a coating. You can lay it on heavy if you choose,but 3 light coats is really all you need.

Looking for magnetic car mount system for N4

I have seen some magnets that attach to the case of a phone then connect to a metal plate on the car or one that connects to the vents of the car. Does anyone make one strong enough to securely hold the Nexus 4 with a heavy duty case?

Yes, it looks like it sticks on with adhesive to the back of the phone.
Yes that is exactly how it works. The adhesive does not work on some cases so I have sometimes used crazy glue. I've tried a lot of systems for in car mounting and this is by far the best in my opinion.

X-Way is great for using vents as your mounting point, but if you want to mount it ANYWHERE you want, then get the FIX-WAY.
I have something simple and a lot cheaper, you might want to consider.
Cellet Magnetic Holder
Here's a youtube video which might explain it better:
http://www.youtube.com/watch?v=PpVahSd3PHU
I can attest that the magnet is extremely strong. The phone will not move at all through any bumps when driving. You stick the magnet to the back of your Nexus 4. I never took off the protective back skin that came with the nexus, so I didn't mind sticking the magnet to the back of the phone. On top of that I use the Diztronic protective case covering the back of the phone. Since that case covers the entire back of the phone, it covers the magnet and you can't even tell I have the magnet on at all. the magnet still works great through the protective case and still extremely strong.

From the reviews it is larger, but stronger maybe. I ordered one in case I can use them together or the other one is not strong enough.
I built a magnetic car dock for the nexus4 that I'm now selling.

Here's a video of one of the prototypes showing how it works. The production version works the same except the magnet is stronger and it has cutouts for headphones, mic, camera, and speaker.

There is a metal plate at the back of the phone or underneath the case....not a magnet...
Metal may have a better effect on inductive charging....rather than hampering it...but this is just my guess...it may disable inductive charging as well....

Anything metal or aluminum will run the risk in cutting down your antenna receptions. Meaning your phone, wifi, nfc, and wireless stuff may not work properly with "metal" backings.

That depends. If you make a metal rim with plastic/rubber to go near the screen of the phone you won't interfere with the internal antennas but as soon as you move down you will cause major signal degradation. It can be done. There just won't be much metal.
