People, people, think of what you are doing by putting paper or dollars in your phone! This is like putting insulation in the phone. The result is that it will make the phone hotttttttt. Don't complain when your phone overheats and fails. Remember that the battery is being charged and a hot battery makes the operating system fail.
iv been doing this for a while until i got an id and dl and needed a wallet

If you put money in the back of your cell phone and you lose it or someone takes it, you have just lost two things of value, not just one.

when you lose 90 dollars worth of phone, a dollar bill doesn't really matter

You paid $90 for a pile of Samsung ****

I see you were hood winked. I had the misfortune to take on a contract phone that was a Samsung P200 and it was a constant pain and money drain from the dropped calls, miss billed and charges applied for roaming when my provider was "In Area" and so on. I then switched to a Sony phone and have had no problems with it and it didn't require "Software" to allow the phone to charge via the USB socket of a computer. One thing Samsung phone look for when stuffed in to a USB socket is if the machine is Windows, under Linux the P200 charged no problem but under a M$ operating system it would simply declare that USB charging was not available. Install the Samsung suit and what do you know, USB charging is suddenly available...

A lesson to the wise, aware and privacy conscious... Most products that "Require" software to perform the most basic of functions should be treated with suspicion and especially where your device holds personal stuff like contact lists, etc.

I have to say the newest sony phone I have appears to have gone down that route yet the old sony phone which is about 2 years old now works a charm and charges from any USB without the requirement of software.

and anyway, this phone is prepay... I only ever get charged for texts and calls. USB charging and stuff doesn't need software, you just plug it in and it comes up as a USB storage device. i think mine is an sgh-b520v so its probably different

Resorting to rude comments about ones mother who has been deceased some 15 Years is not funny and shows you have the maturity of a 6 year old.

I don't have any instruct-ables as I don't believe in reinventing the wheel, most of what I would have instructable'd on has already been done, done again and over done by some other person.

When you sweep away the kiddied building Kernx / lego crap and FLUNKERS like this, as well as all the illegal stuff like dumpster diving, it is illegal as is using power from a telephone socket and other dangerous or downright stupid stunts guised as instruct-ables... you begin to see some truly ingenious inventions.

Its time waster posts like those that make this site look trashy and less appealing than when it first started.

I now prefer to use eHow sites as they are more "Educationally" geared and better structured.

I come here to keep up to date with any changes in some of the projects that are on this site that are truly worth the time to spend.

So go play with your lego or kernex or whatever the latest whiz bang toy is the sliced bread of the moment.

Maybe a sheet of Nitroglycerine will be better if you are trying to kill yourself.

Its an explosive. This method is extremely dangerous, I suggest another hiding place.
Me too! this is awesome!

YET another "FLUNKER" posting a "FLUNK" which is a term that describes pointless posts on sites like these where you find that people with too much time on their hands post utter drivel like these items.

grear man like the idear but what happans if you lose your phone or your friend taks it
One. (author)  skoolerror25 years ago
 umm, i dont know. i guess you're screwed if you lose it, but wouldn't your friend give it back if he took it?
i gess so
That was pretty anti-climactic.
Not really a "secret compartment". It just a compartment. And it's a pre-made one; you didn't give any instructions on how to make anything etc.

This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!
