[Q] HTC HD7 water death!!!!

Hi guys, I recently fell into the sea by accident and my phone was in my pocket and it got wet. I did not know what to do and i thus took out everything and wiped it dry and then plugged it into a power source. No response. After a few tries, it started vibrating madly and the light on top of the device started flickering. The phone started heating up like mad until finally i switched off the power supply. Now it is not giving any response. Please Help!!!

you fried the board.

In future if you ever get a phone/anything electronic wet, immediately remove the power source (battery) and leave it to dry in a well ventilated place for a long time (or a bag of dry rice, which can draw the water out). And when you think it's dry, leave it a bit longer still!
Don't be curious and try turning it on "to see what the damage is", as you will invariably cause more damage.
Unless it's tap water that's spilled on it (or it's been submerged in) you will likely want to wash it out before drying it - pure, deionised water is good for this. This might seem mental, but it's not - pure water is generally harmless to electronics unless there's current running through them. The residue from dried seawater or coffee will cause short circuits and damage the thing, so best to wash it off.

Seawater? Ouch. If anything salt will kill the motherboard faster than the water. But yes, you made a mistake by plugging it into a power outlet after drying it out. Next time (which hopefully does not occur), pull out the battery, dry it out, and stick it in a bag of rice or silica gel packets. Waiting a few days before touching it would also be a good idea. You may be able to try this now and to rid of the salt, soaking the phone in 100% rubbing alcohol (only 100%!) may clean out the internals. Good luck!
By the way, I haven't tried out the alcohol method but it was suggested by other forum members. The worst case scenario with the alcohol is that some of it seeps into your screen and won't evaporate, so try out the rice first.

It's a common misconception that water conducts electricity. In fact, it's salt water that conducts electricity. The problem is our skin has minute amounts of salt on it. It has been tested already making a completely water submerged PC as an advanced cooling method such as using cooking oil. The plus side is for circulating, water isn't as thick & flows faster plus it don't "go bad". The downside is you have to be very careful not to let salt get into the water & how hard it is to find "pure water".
P.S. DO NOT TRY IT YOURSELF. Even Mineral Oil can be dangerous to PC parts if you don't know what you are doing, plus Oil dissolves rubber & plastic parts over time.

Are you joking? Water conducts electricity. Distilled water (saltless) conducts electricity. Mineral Oil != water! And it does not conduct electricity (the pc cooling projects).

You may be right that distilled/Pure water conducts electricity, for that matter everything conducts electricity if enough voltage is applied. Even air as proof by Lightning. Computers run on 12/5 Volts though (except the Power Supply that turns 220/110 Volts into 12/5 Volts). This is not enough voltage (the 12/5 Volts) to pass through Pure Water. The point is people have tried it & it works. Would I recommend it to someone, NO. As I said, any contaminants will increase water's ability to conduct electricity. There's parts in the PC that can give off salt & other contaminants into the water. Our devices work on less than 5 Volts. If you take the battery out immediately & let dry out completely. You can save the device. I've done it myself & helped others save their doing this. The best choice for a advanced cooling system is this 3M liquid, but it's extremely expensive.

Excuse me, Distilled water has no free ions which are found in normal tap water (minerals, K, Na, Mg, F) that's why it won't conduct electricity, but as " drkfngthdragnlrd " said at extreme voltages not currents, it totally can and that's what's exhibited in stun guns for example where air itself connects..

How water resistant is Mi 9 Lite really?

I noticed that my Mi 9 Lite has a rubber ring around the sim tray and in a teardown it seemed to have some rubber around the type-c port too. Would it be okay if I wanted to wash it? Would rain hurt it? tyvm

Even if it did have an official IP rating (which it doesn't), I would strongly recommend against washing your phone. No phone is %100 waterproof, and even if everything seems fine at first long term exposure to water can (and probably will) cause various problems down the line. If your phone is dirty try wiping it with a microfiber cloth dampened with a few drops of isopropryl alcohol, or use one of those wetwipes for cleaning glasses.
Your phone should be fine against light rain and small splashes of water, but always practice common sense when electronics and moisture are concerned. Remember that no warranty covers water damage.

Question Emergency help need to recover my phone

Hi guys
My phone was dropped in the water. I gave time to it and make it dry by hairdryer and put it in rice to absorb its humidity. Then I opened the back panel and made it drier. INow when I press the power button nothing happened. Just when I connect it to the charger, the charging logo and then start screen appear and shows 1 percent charge, is charging and then disappear. it repeats without starting normally. What is your remarks folks?

Something is shorted, just send it to someone to fix it and tell them it's water damage.

Disconnect the battery immediately.
Rice does nothing.
Get some anhydrous (99%) isopropyl alcohol* and liberally flush the entire phone with it to absorb the moisture.
Use low pressure compressed dry oil free air to blow out as much of the alcohol as possible.
Do it in a dry room and it is flammable.
After you get it as dry as possible allow to dry in a warm, dry room with a fan on it.
Let it rest for at least several days.
Reconnect the battery and see what you got.
* never use isopropyl alcohol or any solvent around an LCD display, it will poison it. Should be safe for AMOLED displays. Try to prevent it from getting in between the display and the glass if that can happen.
Use your best judgement.
The more you can safely disassemble it before flushing it out the better. Be aware that individual assemblies like the display and mobo are sensitive to ESD damage when out of circuit.
In a dry room handling them is risky if you disconnect the ribbon cables. Unfortunately this is exactly where water tends to get trapped.
If you disassemble to subassemblies level raise humidity in the room to 50% and use a plain wood surface, or earth grounded ESD mat to work on. A ESD wrist strap is highly recommended.
It may be best not to remove the ribbon connectors other than the battery, flush it well, and allow more drying time.
Either way you want to dry the assembly in a warm dry remove to remove all residual moisture; it must be completely dry before powering up again.
If any corrosion formed as a result of the water exposure especially with the battery connected it will not be salvageable.

Lol, that sounds more complicated than having a heart transplant.

Well once you get a device wet, speed and appropriate actions make the difference between a paper wieght and a working device.
At least I gave known good advice*. Manufacturers won't even attempt to salvage them because experience has shown it's not worth it.
*dropped my Buds case in a full coffee cup (cream/sugar). Immediately pulled it out and apart. Flushed first with RO water to dissolve any sugar then flushed with anhydrous isopropyl.
A day later it was charging again. 2 years later it still works. And that was with the battery in it.
The coffee was still drinkable too

can a brand new phone ip68 phone get Water damage ( xperia 1 ii )

so i just got my xperia 1ii today, i was wiping the screen with a bit of wet cloth before sticking on the screen protector, then i saw mist on the front facing camera, next thing i know it screen starts to flicker and turn green, then it died, it was a sad day for me, is it possible for water to get in an ip68 phone when brand new?
it was also kinda my fault for using wet cloth, but like all my other ip68 phones this never happened to me T _ T

WYSIWYG... yes it's possible.
Never assume the seals are intact. Protect from water exposure at all times is what I do.
Will Sony warranty cover it???

I am not sure about Sony's warranty on user error.
There is nothing in the box stating anything about warranty. I bought it online but there is a physical shop that I collected the phone from.
I left it in a bag of rice for 10 hours but the screen still turn up black screen with some odd lines and shut itself down, I feel so dumb for causing this, I usually do the same way of installing screen protectors for my Z3+,Z5 and XZ and water never got in, I feel so embarrassed and unlucky T_ T

Rice Doesn't Work!
The phone needs to be powered down and the battery disconnected asap. Otherwise it will likely be destroyed if it isn't already. It needs to then be completely dried out.
-or-
Battle it out with Sony.
Obviously the first option is incompatible with the second option. I'd send the mess back to Sony, they may or may not suck it up easily.
Sony is a pain to deal with...

Sony is hard to deal with, ya so I've heard, too bad stores are not open today or tomorrow need to wait till Monday.
damn it I bought rice for nothing.

I know Sony well, as I have torn into them multiple occasions. They are rotten to the core.
That however doesn't mean that a loose chainsaw can't find an artery
I'm one of the few customers who's gotten a refund check and spoke with a VP in Teterboro NJ. They are slime... the VP's are the worst; a midlevel manager is more likely to help you if you slip through one of the cracks in customer support.
If they take back without trouble, fine.
Otherwise better buckle up Dorothy, it's going be a rough ride.
Did you use a MC or Visa to make the purchase? If so you got leverage...
Send unit back for refund of replacement and do a charge back through the bank.
Do you want another? If not be clear you want a full refund.

Here's the thing I live in Malaysia, I bought it online, and these guys are a small retail start-ups.
They Imported the device from Hong Kong cause we are kinda short on phones that are price above $600. Malaysians don't really spend much on buying new phones hence the difficulty to find high end phones locally, especially Sony, not a popular pick in recent times.
Visa here doesn't even provide any leverage hahaha.
would try to send it back to their local store tomorrow.
I would actually like to get replace to be honest, but some how I have doubts in my mind saying that its gonna be super thought ride.

Have the rear cover removed, disconnect the battery*. Is there visible water in it?
Get out as much as possible.
You need a warm, dry room. Lay on side with a high volume fan on it. Let sit for a couple days.
If you can get anhydrous isopropyl alcohol** carefully flush with that to remove the water. Use care as if it gets between the glass and display it will leave a water mark. Then dry as above.
All connectors, everything must be 100% dry before you reconnect the battery. The room must be dry, heat drives out moisture; use a hot box if you must. Keep temperature under 110F. This may save it...
*the sooner the better.
** never use methanol or isopropyl that isn't at least 96% alcohol. Never use any solvent including isopropyl alcohol with LCD display, it will poison it!

I don't dare to remove the back cover, wont that void the warranty?

I think water got in the LCD connectors, cause last time I turn it on I has weird flickering and turns green with vertical lines.

Yes it might.
That's a AMOLED display not a LCD...

I got some silica gel put in an air tight jar, its been sitting over night since yesterday, hope it turns on tomorrow, or else I am gonna feel so awkward when I bring it to their store.
Damn I've never brought a Xperia phone or any phone in for water damage or any sort of claim warranty before, its giving me the shakes.

That will do nothing. Do Not power it up.

[UPDATE]
So I brought it to the store, there was a bit of resistance there, but in the end they allow me to bring it back in for a check.
They say hopefully there is no red on the water damage sticker, cause if there is, they cant help, but if its just faulty they can replace the phone.

Heat drives out moisture. You need air circulation as well for best results. With a sealed phone that isn't going to cut it.
First any free standing water needs to be dumped out... that's sort of funny, but true.
If you every dealt with flood damaged cars the magnitude of the problem becomes clear. Powered on circuits can be damaged irreparably in a short amount of time. A lot depends on the conductivity of the water and how long it sits there. If the battery was disconnected the car may be salvageable.

Heat can help but the point is to make the air inside the bag extremely dry. Air readily absorbs moisture, which eventually evaporates. Very true about keeping everything turned off; while deionized water is non conductive and won't bother anything, most accidental spills and drops are in contaminated water which not only can be conductive, but may leave behind trace elements as it evaporates.
Still, I've had quite good success with desiccant rescue bags.

I've cleaned thousands of circuit boards over to remove the flux. Sticking them in a sealed container with dry air is one thing I never did to dry them. Anhydrous sopropyl alcohol is an excellent cleaning/drying agent for most electronics, but needs a dry room to avoid condensation as it evaporates. Dry warm/hot air with high air flow is best for both isopropyl and water. Most times I also used compressed air to knock off the solvent/water beads then dry the pcbs. A high air flow blower of a large shop vac was another favorite for drying them.
Heat drives out moisture ie hot box. Hot boxes have been used for over a century especially in humid climates to preserve surgical instruments, camera equipment and electronics. Works regardless of the outside humidity. The box or cabinet is sealed but not completely air tight.
The surgery room at Pennhurst actually had it's surgery instrument cabinets lined in the back with steam heated radiators, circa about 1900.
They had large glass doors.
You could vacuum dry it though as this be very effective but again the cover should to be removed at the minimum. It's easy to make a small vacuum chamber, the vacuum pump doesn't need to pull a high vacuum to work well at a warm temperature.
Desiccant bags are best used to keep sealed items dry rather than to remove water per se.
I use them to protect lens.
As for the conductivity of the water it's a crap shoot. It could be mixed with sweat, be acidic, or otherwise contaminated.
I used RO water to flush my Buds case when it fell into a full cup of coffee, cream and sugar. The RO water to chase the sugar, then anhydrous isopropyl alcohol to chase the cream and water. Allowed it to dry in the sun and in a room for a day with the spot welded battery in it. I had the case torn apart and flushed within 5 minutes. 2 years later it still works normally. I drank the coffee after I cleaned the case, perfect day

Silica gel works to a degree on my phone, the screen was able to turn on with the start-up logo but as soon it turns on it restarts itself.
I guess two day wasn't enough, especially on phones that are partially sealed, but I guess its true, not all phones are made equal when it comes to waterproof, I remember my XZ was completely waterproof, the swimming pool kind of waterproof.
Its like buying a lottery when you get a phone that fails its waterproof.
still waiting for update from the seller hahaha.

Phone was fallen in to the water and wont turn on. Need help!

My Samsung mobile phone has fallen into the water because of my fault. But soon after I took it from the water I turned it off. Since I have never faced a situation like this before I searched for some instructions using the internet on my laptop. While searching on the internet I found some directions to solve this and save my phone. But after following those steps still, the phone won’t turn on. To fix this phone,
Soon after I took the phone from the water I put it in a rice bag to remove the water inside it (Nearly 24 hours).
De-assembled the phone as I can (It has a non-removable battery)
Put the phone inside a rice bag for 6 hours and tried again.
But the phone won’t turn on. Is there any other way I can fix this phone? Or should I take this to a repair station?

Rice does nothing.
Pull the battery asap. The phone must be completely dried before connecting the battery again. Pull the rear cover, disconnect the battery and place on side in a warm/hot, dry room with strong fan on it. Give it at least 3 days.

You disconnect the battery via it's ribbon cable.
Even when powered off there are circuits that have power going to them. This current exacerbates the corrosion and destruction of key circuits.
Anhydrous isopropyl alcohol (>96%) can be used as a drying agent. LCDs displays can be poisoned by any solvent, do not use on LCDs.
Flush liberally with isopropyl alcohol then get as much as possible off the assemblies as fast as possible in a dry room. Isopropyl alcohol is very hydroscoppic and will grab moisture out of the air, it also cools as it evaporates, attracting any moisture in the air. It is flammable...
After doing this allow to dry for 2-3 days as described in previous post.
Avoid getting the alcohol between the display and glass as this would leave a residue stain. Use best judgment... only use anhydrous isopropyl alcohol not methanol!

Bare in mind there are BGA chipsets in this phone as in most. Water can seep under the chipset and will take longer to dry. The connectors can also retain water and take longer to dry. Place on side to help in draining.
Low pressure compressed dry oil free air can be used as well, but carefully. A shop vac blower... carefully. This can also created an Electro Static Discharge hazard though. Don't touch the phone and nozzle or vac at the same time. Dry air raises the risk of ESD damage. Earth ground yourself before touching the phone; a ESD mat and wrist strap are preferred. Be aware of this hazard. Generally in circuit assemblies are relatively well protected. Points on the mobo can lack input protection and it's best not to touch them.
Heat drives out moisture ie hot boxes that are still used in humid climates to provide a dry environment for humidity sensitive equipment. Up to 120F is perfectly safe for drying. Don't expose the display to direct sunlight to speed drying though. Good luck.
