Hello Guys, I heard that ISOPROPYL ALCOHOL can clean the dirt inside the Phone, I watched on the YouTube how to fix it but they have to separate the board. Now my question is, it is Ok to submerged the whole phone on the ISOPROPYL ALCOHOL without separating the board and camera? and Mic also?... help me please. thank you very much.
Most definitely not .
From my personal experience, once the phone has water damage, it's impossible to fix it.
The best thing would be to completely disassemble the phone and pack the parts in a bag of desiccant for a few days.

Hello
I put the phone on spilled beer. It quickly turned off and after 2 days it looks like this:
Is it possible to clear the display?
Something similar happened to me, allbeit without the beer, was in my pocket and got wet. Could still see and use the screen. After a few days the "blotcheness" cleared up, been fine since.
you should disassemble it and clean with electronics cleaner or isopropyl alcohol ..

As easy as that eh? Try not to destroy your bonded LCD and touch screen layers in the process....
Hi,
I accidentally dropped my cell in water, touch sounds and ear piece stopped working but i blowed some air in headphone jack so it started working. But i think it will give some problem in future as water makes its way inside everything.
Any idea how can I do some proactive steps like using hair drier or apply some heat blow????
DUDE. You should put it in a sock full of uncooked rice or bigas over the night. That's the best way to drain the water as uncooked rice absorbs water.

I dropped my old phone in water once.
I opened the back, took the battery out and put everything in rice.
A few days later it started working again.
With the Nexus 4 however, since it is completely closed, it may be a harder decision to make what to do.
I think things like a hairdrier or excessive heat may damage the phone if not done properly. Rice actually imbibes the water.

Take it apart and rub all the circuit boards with rubbing alcohol, that's your best bet, I saw in another thread where it fixed this guys phone
Sent from my Nexus 4 [NEO @1.836 GHz] on [PSX v4.1 4.3]
So my lg v20 took a dive into some water. Now it boots up but I have no touch screen response. Also when I turn the screen off then back ok again I only get a faint back lighting. I've replaced the screen and digitizer and factory reset with no luck. Any help?
I'm afraid you'll have to do more than just replace the screen and digitizer...
there are probably dry water residues all over your mobo circuits too... which cause malfunctions at best, but soon could end killing your device for good.
you should send it for repair... personally with old electric stuff I would take it apart, piece by piece, and wash it with isopropyl alcohol (if it's jsut water), but again, this isn't something I would do on a new device, actually I have never tried it on a smartphone...
I'm afraid you will have to ask some professional to fix it

This guy gets it. Just get an eyeglass kit from a dollar store, the screws on the back of our device are phillips theres 20 something of them. Watch a tear down video and take it apart and buy the purest isopropyl you can and wipe it down. My cats knocked water all over my girlfriends mouse and i took it apart and cleaned it and let it dry for a day or two and its sort of functioning, 100% at times and others at 60%. Good luck mate. Try telling LG its bootloop issues ;P
Thanks for the help guys. I'll give it a shot!

water, gravity and concrete are the v20's nemesis.

Im planning to replace my battery because its 2 years old by now.
Last week my display was replaced under warranty by Samsung, and a new back-cover (with adhesive i guess) was also placed.
Samsung did not replaced my battery, but im planning to do this by myself. Repair guides are easy to follow, so that wont be the problem.
However, in these guides i cannot find anything about adhesive. So my question is, if the backcover and battery comes off, do i need to replace both adhesive layers (backpanel and battery) if i reassemble the phone?
Hi,
This is highly probable. I know some people are extremely careful while removing the back piece and the adhesive stays intact. As for me, I had adhesive tape glued to new backplate I have ordered so all I had to do was to remove any residue left on the frame and put everything back together. The phone is still waterproof.

Well for me its just the battery i need to get replaced. I ordered a battery, but no adhesive. So if i remove carefully, is it mandatory to also replace the adhesive?
If the backplate survives and you ARE careful you should be good. Warm the sides with hair dryer and push it hard back so it won't separate. Not sure about the waterproofing though.

Don't really care about waterproofing. However, What do you mean with "push hard back"? Just like hair waxing and then pulling?
So the used adhesive sticks back
Does anyone knows if the battery cycle count using this method resets with every rom install (clean flash), or is the state of the battery itself?

Hello,
my Redmi Note 7 fell in the water of our harbor and it took ~15min until we were able to find it. The water was ~1 meter deep.
I put the phone in rice for 4 days strait away. At some point the phone started but was discharged the next day. After that the phone did not start or charged anymore but showed a battery symbol.
We took the phone apart and cleaned everything with pure alcohol. We replaced the battery too. I took a few measurements: There is 5V on the battery test point and 4.8 V too.
At some point the phone showed 80% while it was off and attached to a charger today.
At the moment the screen goes on for a very short time ~1-2 sec. when powered on but does not charge when connected to a charger.
What could I do to bring it back to live?
I mean there are working parts in it as it looks like.
It's DOA.
The only way to save it was to pull the battery asap (in salt water even that might not be fast enough), disassemble, flush liberally with warm RO water, flush, flush, then flush with anhydrous isopropyl alcohol to absorb the water, dry for at least 2 days with a fan in a warm room.
Water is the best solvent for brine...
What has happened is water/alcohol insoluble corrosion has formed on contacts and any exposed conductors. BGA chipsets, flat pack ICs, power circuits and PCB traces may be shorted out completely especially V+/ground rails. Once this happens it's beyond salvage... sorry.
You could try a pulling all connectors and dumping the whole lot minus the battery and frame into a mild acid bath for an hour then rinsing throughly with RO water, then isopropyl alcohol, drying etc. Which acid, concentration, and time? Probably very diluted sulphuric acid. It's a mix of copper, silver, tin and more alloys you're trying to clean.
That's the only way to remove the corrosion if present. The acid could easily destroy exposed (no conformal coating) fine pitch PCB traces. As long as any corrosion remains it will continue to corrode.
I don't give it a good chance of working...
Oh man that sounds bad. I thought there would be a chance as it was more sweet water than salt water and the phone worked after the incident for a short time.

Disconnect the battery.
You can try disassembling it again. Pull all ribbon cables and connectors. Place in warm/hot RO water, clean contact surfaces the best you can with a toothbrush or a ultrasonic gum cleaner if you have one. Try to get some water flow under the BGA chipsets.
Replace the RO water at least 2 times and leave in it for a couple hours*.
Inspect contacts, surface mount devices, traces, etc with good light and a optic aid for signs of corrosion damage afterward. If none if seen proceed to the 99% isopropyl alcohol flush and dry completely. It might work....
*water may get in between the display and screen. If so it will leave a residue upon evaporation. This must be purge before reassembly. A vacuum drying chamber can be used. Use your best judgement how the proceed with the washing phase depending on this issue.
If it's sealed, no worries otherwise you may wish to modify the washing phase to be less invasive by limiting time and exposure to the display.
The contacts on the display is what really needs to be cleaned...
Today I found the phone is alive indeed. After lots of cleaning with alcohol it came back to live. Everything work.
The only issue I have is water (or alcohol) in the display now. This causes little clouds of brightness and the many random touch events.
Its there something smart I could do to get rid of this last bit of water except a vacuum chamber. It might vanish if I heat up the phone for several hours near/on the heating with a towel in between (not to hot).

It's never a good idea to clean everything with solvents such as isopropyl. It can weaken many of the adhesives used in electronic devices, and it will ruin your display panel. If you have access to a temperature chamber, you can try removing the battery, putting the device in a bag of rice or desiccant beads, and let it heat soak for about 2 hours at +60c.
Chances are your display and touch panel are ruined, however. NEVER soak a device in alcohol or any other solvent.
Well the alcohol "everywhere" was an accident and bad luck. It happened while I cleaned just the last parts and connections. I will try to remove the battery and put the device with rice somewhere warm with a thermometer to check the temperature.
Thanks for the help. I will report what happens next.
I am able to get the few messages and photos from the day it fell in the water now. So I am near a 100% data (backup from ~2am + current backup) rescued scenario very soon. I am very happy to have reach this point so far anyway.

The accident was dropping it in brine water... without through rinsing it be a goner. Even with rinsing it still may eventually die.
Rice does not work. Heat does*.
Be patient.
Warm dry room with fan on it.
The problem now isn't drying but the residue left behind as the water/alcohol evaporates. Try using centrificule force to move the water although capillary may prevent this.
Try drying on end.
Careful use of a shop vac might work in a dust free room but could destroy the display. Use best judgement. At the worst if you just let it dry it probably will leave some water marks, maybe not.
*raise heat to 110-120°F if it's not drying after 2 days. Heat displaces water ie hot boxes used in tropics.
The phone worked perfectly with clouds of water in the display.
After I put the phone in a warm place to get rid of the last few parts of this moisture the screen was black and stayed this way.
Now the lowest part of the phone gets very hot when switched on. Its hot enough to burn your fingers. The funny thing is that with "scrcpy" I am still able to reach the screen and the OS works perfectly as normal. I guess the lower PCB with the USB-C is the part which gets this warm.
I am angry for myself as I could have lived with the few clouds in the display as a reminder to keep water and smartphones away from each other.
Better than broken ribs...
You would need to carefully separate the display from the glass and clean both. Probably bonded with a heat adhesive.
The hot running suggest the phone isn't completely dry or has damage. Pull the connectors off the port pcb and inspect both them and that board for visible corrosion damage.
Reexamine the mobo's power section for same.
It's all probably academic as it likely will fail completely in time. Rust never sleeps.
