back to article Police turn to extreme-sport mobe sucking

Mobile forensics company CY4OR is offering police silica-lined bags, into which they can drop waterlogged phones in the hope of extracting the water, and therefore some useful data too. The bags have been knocking around for a year or so, under the Bheestie brand and sold to those who think they might drop their phone in the …

Mobiles and water

My wife once dropped her Motorola clam-shell phone into a bath full of water. It stopped working (the phone that is). After being left to lie for about 2 days on the table it started working again. It worked for at least a year afterward (until the upgrade came through on the contract and she chose another phone).

Maybe not water ...

> drop his phone in a glass of water making it impossible to read

but there are many, many corrosive liquids readily available to even non-master criminals that will do the trick.

Nope.

Cola aint that strong, what-ever urban myth might say.

Coke or Pepsi

It's not the acid, it's the sugary crap crystallising on things and generally gumming stuff up.

ah but

the sugar crystallises on the surfaces when dry, affecting the electronics where water evaporates away, often with no real residue

Sugary coffee

I used to come across users who had spilled stuff in their keyboards years ago and most of the time, a good rinse under the tap and careful drying would sort it out. Sugary coffee however, if it wasn't washed off more or less immediately made a right mess, eating into the copper tracks and gold leaf. Nasty.

If It Fell In The...

...ocean, a good rinse with distilled water might be a great help.

Water is not particularly damaging to electronics, an hour in the sun revived my GF's waterfall dropped camera. But a single drop of ocean water rendered another "unrepairable."

As to killing phone chips, keyfob memory, etc., methinks a minute or two in a microwave would be quite irreversable.

211 seems to wipe my memory, just not for long enough.

$20 Seems a bit steep

For a ziploc bag with some silica gell in.

Esp. as sitting on a warm radiator for a couple of days normally does the trick.

Inexpensive Alternative

Immersing the item in a bowl of dry, uncooked rice would seem like a less expensive and equally effective alternative.

@Mobiles and water

Could have been useful a couple of weeks ago when my son dropped his iPod touch in the bath ... fortunately a week in a box of rice on a radiator seems to have recovered it. However his (fortunately fairly old) mobile wasn't recoverable when a month earlier he'd left it in the pocket of a pair of trousers that were destined for the washing machine!

Washing machines....

Yeah, washing machines are a pretty good iPod killer - as i have found to my cost!

[this is me checking my coat before washing it form now on!]

Motorola Clamshell...

Scuba diving off the coast of Southern California and found a Motorola clamshell on the bottom at 45 feet. Took it into work and dried it out and we were able ti power it up. Had been on the bottom for ~30 hours. Original owner was very surprised - He had dropped it into the ocean while fishing.

Welcome our new "top tips" masters. For myself, I've got enough of the 'do not eat' stuff saved up to fill a bin bag.

small boys in the park... phones for goal posts

And then a thunderstorm... and then forgetting the phone completely -- which then starts calling the mum... Small cries, indeed.

Anyways. a bag of rice for a couple of nights did the trick.

A side note: if you put rice kernels in your salt shaker to keep salt from caking... what do you use in your bag of rice?

Mucking About With SPOC

The handset might give up its information without mucking around with a Single Point of Contact officer, but I don't think officers will want to be doing that too often..

Unless it's a life and death thing, I believe bobbies are generally expected not to bugger about with phones they find, for A) there are privacy, surveillance and data protection issues; and for those who don't believe the police concern themselves with that sort of thing, there's B) the understanding that evidence may be lost if untrained people just mess around with devices without any guidance.

Bureaucracy

Not just evidence lost, but made unusable in court.

This bag is something that could be part of a written-down procedure. You put the item in the bag and do the usual marking and signing of the bag, and then it goes to the experts.

Whether you can have something such as washing in distilled water done at a preliminary stage, I'm not sure. It protects the electronics, but how often would that be needed?

Checking a phone for a contact number is becoming a routine thing for such people as ambulance crews, so there must be some slack in the evidence requirements.

USB keys + salt-water swimming pool

I've taken my car-key alarm fob and attached USB keys swimming twice now. The USBs have long since lost their little snap-on covers.

An hour in the sun and they're as good as gold.

Apply slow heat.

boring but true, and hopefully useful:

if you get your phone soaked, first thing is to take the battery out immediately - its voltage on the PCB tracks which accelerates corrosion 100x.

the phone can then be dried out at leisure

if its a li-ion battery, be careful to tap any trace of water out of the contact area - there is always a tiny battery protection PCB which is permanently powered and will corrode - if this happens you will need a new battery but the phone should be OK. you can try blowing the water out witha straw, or using a hair dryer - but be careful not to get the battery too hot. .

what's wrong with...

What's wrong with just dismantling it and sticking it in the airing cupboard for a day or two? always worked for me!

If it's something nastier than just water than a quick wash with purified water prior to a drying should sort it as long as it's not been submerged for a long time...or in acid =p

Thats nothing

We found an old nokia out in a field in Arkansas USA (where extreme weather events are normal, -20c in Winter +40c in summer, lightening, hail, long frosts, and bugs etc).

We powered it up and called the owner thinking it had been there from the previous day when a brush hog had been out there - it turns out they had lost it there 18 months previously!! I doubt my iphone would survive the same.
