Phone get wet? Heres a way to fix.

post #1 of 12
Thread Starter 
This is cut and pasted from another thread. I thought it would help alot of people so I created a new topic for it:

It's not the water that hurts the phone, it's the corrosion that happens inside after it gets wet. If it's saline water, it can happen in an hour. (DO NOT place your phone inside an oven, or use a hairdryer to dry it. This will destroy your phone for ever.)
Let it air dry for 2 days, with the battery out and the back off. 1 day, if you place a fan on it.

Corrosion inside a phone looks like white powder or mold/mildew on the PCB. You can actually fix this by takin a very light amount of TECHSPRAY (contact cleaner. 80 percent alchohol or better) on a toothbrush and scrubbing it off. It will prolong the life of your phone, and/or if broken due to water damage, its possible it will fix it. Due to the high quality contacts, corrosion happens near instantly after immersion. Most people think the damage comes from shorting out the phone. This isn't true. The battery itself can short, but that happens very very rarely. even after sitting in a pool for a couple hours.

Very quick way to tell if your battery is bad is if it's swollen. Not a large amount, but feel it. Does it feel swollen in the middle? This can happen when a battery goes bad. Due to #1 age, #2 overcharging with a car charger and #3 water damage.
It's hardly noticeable. I can tell by eye from experience, but when I first started we had a tiny level that we could see if the middle was raised slightly...

The achohol used has to be very strong because the higher the alchohol percentage, the less water and other fluids are included. Techspray is contact cleaner. Pure alchohol basically. This is what you want.

It's what we use to fix waterdamaged phones (when possible) at verizon... Hey, since I'm a cell phone tecnician, could this be counted as a FAQ? I'd like it to be. If more info is needed, I will certainly supply it. Anyone know whats required to be considered a FAQ?

EDIT: I guess this could apply to motherboards as well.. if someone spilled something into their computer... However considering the voltage running through, liquid damage CAN short out a computer rather quickly versus a cell phone which is almost impossible to short out.

IMPORTANT: This is a little deceitful but on the battery or behind the battery on the phone itself is either a white circle sticker looking thing, or on a battery, a white piece of paper with some red lines on it. If your phone gets wet, these change color. The battery indicator is like litmus paper and will bleed the red lines out, turning it pink. The white circle found on most motorola phones and other brands has ink underneath that will bleed red if comes into contact with liquid. It will void your warranty if any tech sees this, or you try and send it in for repairs. So buy a new battery or remove the sticker before letting any tech see this. They don't always turn color when they come into contact with liquids, depends on severity, luck etc...

Huh, interesting, I always thought it was usually the shorting that wrecked phones. And this "techspray" is new to me as well.

But my fix when I wash my phones is to take off the water void sticker and ship it back to Verizon for a new phone...LOL

Good info though, rep +

My water-void sticker is recessed in and sandwiched in the casing.

My phone made it though the wash once. All I did was 1) NOT TURN IT ON and 2) open it all up and aim a hair dryer at it for a long while. Then turned it on the next day. Good as gnu!

Of the phone or battery? I've never seen an indicator that couldn't be removed. And well, I've worked on every phone from startac's to prototypes not released yet that idiot beta testers screw up...

Yeah, it's not the water that hurts it... the corrosion inside your phone will cause it to fail maybe tomorrow, maybe 6 months from now. I'd suggest opening it up and cleaning it out.
By the way, you got lucky with the hair dryer, those can kill a phone and is worse then water damage. Never let your phone get above 120F for any amount of time.. even seconds could cause LCD failure, solder to leak on the pcb crossing connections, which WOULD short your phone out... Water + phone = Bad... Heat + phone = Worse

The solder inside phones is very weak to heat. They use weak & light solder to keep the phones light, and cheaper to make. So you don't need a soldering iron to melt the contact points. A hairdryer gets hot enough to melt the solder inside the phone.

Yeah, I used the cold setting. I completely un-sandwiched the phone and dried it out.

Aww lame.

On my LG VX8300, the sticker is in th battery compartment.

And I believe there may be one on the battery itself. Its easy to remove.

Just wanna add my I've literally fixed thousands of cell phones, that's what I do at work (when I'm not on the forum ) and have easily come across hundreds if not thousands of phones with liquid damage. Once a phone gets wet there's so many possibilities as to what can happen. No two wet phones are alike. 9 times out of 10, when a phone gets wet it's never gonna be 100% functional again. Symptoms include no reception, power cycling, white LCD, camera flash always on, keypad malfunctioning, battery over heating, phone thinks it's charging with no charger attached, and the list goes on and on...

However, if you prevent corrosion you have a better chance of the phone being somewhat usable. If the corrosion is in an easy to find places and can be scraped off with a brush I have seen certain problems go away. Example, on the keypad of a Sanyo 3100 corrosion builds up from what I think is when people spit into the mic area. This will cause the keypad to not function. Well I've scraped off corrosion from that area on dozens of phones and got the keypad to work again.

Again, it doesn't work everywhere. If you have corrosion say on an LCD ribbon cable it's gonna be very difficult to scrap between all those tiny pins. In that case, you're screwed. Long story short, if you have a good tech who knows what he's doing then there is some hope. But not much when you get your phone wet.

Edit: Can you please prove a link to the original thread and give credit to where credit is due? Thanks.

This happens to all my friends. It happened to me once. I just let it air dry in the sun or next to a window with lots of light. A big mistake I notice is people trying to turn it back on to soon, like after it just happened. Just be patient. Most phones I've seen this happen to ( and I mean completely sumerged in water ) works after you let them dry out.

Actually it was my own post, I just made it's own topic, but I had orginally mentioned it in my watercooled phone thread here:

I'm also a cell technician, been with Verizon 3 years now. Before that I sold them for a few more years... Meeting quota's, decrease in commision led me to go tech since I wanted to stay in the field. You mentioned a Sanyo, I take it your a tech for sprint? I sold for them as an agent (along with a few other carriers) at the time they had a rocking employee plan...
