I have a Samsung galaxy A32.
It went swimming 2 days ago , and now there are areas on the screen that wont register touches or swipes. Scrolling and swiping is janky.
Do I need to replace the screen or some other component? See image from a touchscreen test app.
PS: On the first day, it was unusable (nothing worked) and had ghost touches.
I even unscrewed the back panel and left it out for over 24hrs. Seems permanent.
Pull cover, disconnect battery, now.
Pull as many ribbon connectors as practical.
Get some anhydrous isopropyl alcohol (>96%), 93% if 96% isn't available but not 70/30!!!
Gas dry can be used if it's isopropyl alcohol with zero methanol. Do Not use methanol, it's corrosion.
In a warm, DRY room...
Flush liberally with it. Use best judgment if it get between display and glass it will leave a watermark. Use clean, dry low pressure air if available to gently blow out the alcohol. Otherwise flick as much as possible out by holding and snapping your wrist/arm ie centrificule force.
Allow to dry in a dry warm/hot room for at least 72 hours with a strong fan blowing on it. Reassemble and see watch you got...

I dropped my phone into the ocean about a week ago. It's been in rice since then. I just took it out and it turns on and shows my home screen and gets data and is receiving texts and stuff, however neither the touch screen nor the four android buttons work. I searched and people were suggesting soaking the phone in alcohol for this. Is your any chance that would fix my problem? Maybe it could be as simple as replacing my phone's screen? Thanks for any help.
What I would do is take the phone apart (remove the backcover, battery and unscrew the screws) locate the digitizer flex cable and blow dry it. There may be water left in the component.
Refer this this video on the disasembly.
Probably a bit late but you want to clean it with de-ionized water or Isopropyl alcohol. To be honest i would have put it in a bowl of either of those instead of rice as soon as i got home. I've personally found the rice trick to be a myth,works just the same as leaving it out to dry. Sea water contains high amounts of salt and drying it will just make the salt crystalise.You need to "Wash" the salt out and the 2 ive suggested wont leave residue on the PCB (info from my mum who is an electronics teacher)
Hello guys!
I have a bit of a problem. My cell went down to the toilet and I almost instantly turn it off and sunk it on distilled water... waited some days in a zip lock with silica gel., then turned it on and it seems to work (although the battery seems to be damaged).
My problem is: between the LCD screen there is still water, then I sunk the phone in isopropilic alcohol, did the same but the humidity is still there. maybe vanished on a 1%...
I attached a picture of the screen.
Have anyone an idea of what could I try?
Wash again with isopropilic alcohol and use heater to evaporate the alcohol. At the end of the process you will still have some yellow spots and those you can't get rid off because they are between the layers of the screen

Thanks for replying! I will try that
The bezel on my S2 gets harder and harder to turn over time with just my thumb (or one finger) on one side, eventually getting to the point where I have to grasp it with two fingers to turn without my finger slipping on it.
This is because it gets dirty. Over time, sweat, dust, dead skin, general grime in the air, etc., works its way under the bezel.
The good news is, IP68. You can wash it. I was hesitant about this at first, because water resistance ratings are not as rigorous as we'd like to think. Further, there are issues of static water intrusion (sitting under water) vs. dynamic forced intrusion (a spray of water hitting the object).
Anyway, I've thoroughly cleaned the bezel mechanical interface several times since I got the watch without any issues. Just took the leather straps off, put the watch under running water, and gently worked the dial around, back and forth, over and over until it was moving very easily and smoothly 360.
Dry it off really well, and the dial movement is like new. Boots back up and works without issue.
My display damaged and i wanna to ask you smth guys.
How difficulty is it to change it by myself?
I watch this video "
" and i concluded its pretty easy to change it. But the only tool i dont have is the heatgun the other tools i can buy.
Tell me your opinion. Is it easy to do?
Can't tell if it's easy, but in other situations that I needed a heat gun and didn't have one, I used a hair dryer, which is way more common to have at home, or at least easier to borrow from a neighbor or something like that
Watch tear down and repair vids.
If a repair shop will let you watch them do it.
ESD, learn and understand what it is. Discreet components ie the display and mobo are very susceptible to it out of circuit.
Bare minimum protection is a bare wood surface to work on and a relative room humidity of 50% or better. A earth grounded ESD mat and wrist strap is best
Disconnect the battery as soon as possible in the disassembly process. Discharge below 40% if possible before starting.
Have all the drivers, picks, fine precision tweezers, and tools needed. Excellent light and a 2X or so optical visor be nice.
Inspect for additional damage*.
Have a set of OEM seals and now's a good time to replace the battery if it's performance has noticably dropped.
Take pictures disassembling if needed. It must be put back together exactly as it was.
Do Not over torgue screws... less is better.
Be very careful not to damage the ribbon microconnectors.
Take your time, no rush.
*any impact that can break the display or bend the frame can damage the mobo. High G loads or direct impacts can damage chipsets internally, fracture solder joints and internally damaged multilayered mobo PCB internal traces.
I did it three days ago, bc my mix 3 had contact with water.
Its kind of easy to do with a hairdryer and a small plastic tool.
The hardest part is to glue it back together.
(But I have to say my screen didn't work afterwards. The expert in the phone repair store said its maybe a problem on the motherboard)

If the battery isn't promptly removed and especially if it's not immediately powered down the current can cause corrosion and short out circuits. The power section is particularly vulnerable. Try again, inspect mobo and the ribbon connectors for signs of corrosion and moisture. Use bright light and magnification.
Is it completely dry? A good soaking with anhydrous isopropyl will help remove hidden water. Again dry completely afterwards. Getting the underside of BGA chipsets dry is imperative.
The micro connectors tend to trap moisture too.
Careful use of compressed air can be very useful but the key word here is careful. Don't stick a nozzle with 100 psi an inch or two from the mobo! Either use low pressure clean, dry air or back it up for high pressure air.
Use your best judgment... it's a bit of an art.
After you dry it as good as possible let it sit in a warm, dry room with a fan on it. Complete drying may take days without disassembly.
Thank you for the tips! I will try it like you described
The same is true with flooded cars, promptly pulling the battery can limit the damage even save the vehicle.
Be wary on flood damage vehicles for sale now, always check for water lines/marks
Most will suffer impossible electrical problems forever. Brine water always kills...
So I didn't get the insurance for my wife's Pixel 4a and it (and my Pixel 4) were submerged in water at Busch Gardens for about 5 minutes at about 3 feet deep. My Pixel 4 works fine and hers is dead. They were both in a plastic "protective" phone bag that was fully sealed. Somehow water got inside the bag, maybe a tiny pinhole I couldn't see. It's currently sitting in a bowl of rice as I don't have any silica gels at the moment. It's been in rice for over 12 hours but still won't start and I can still see condensation inside the camera lenses. She is currently using my old Pixel 2XL so we're good there. I am hoping I can bring this back to life. Any ideas?
Hardly would you be able to sort that out. I have managed to get mine out with rice but that was before the damage became irreversible which is your case I guess.
Please keep us updated.
So did drying out the phone work ok?
Forget the rice... voodoo would work better.
You need to take off the rear cover asap and disconnect the battery to avoid permanent damage.
The clock is ticking Mr Wick... tic-tok...
Use anhydrous isopropyl alcohol* to absorb the water. Flush liberally but make it fast. Displace as much as the alcohol as fast as possible next.
Low pressure (10-15 psi) compressed clean air can be used. Best done in a dry room to prevent condensation. Remove as much as possible.
Allow to dry in a warm dry room with a fan on it for at least 2 days before connecting the battery.
You could forego the isopropyl alcohol and just use this last step extended to a week but no water can remain. I reccomend using the isopropyl for large amounts of water. The BGA chipsets have their contacts under them, these must be 100% dry... you can't visually inspect them. All switches and micro connectors must be dry. No water at all in the phone when done.
Next time double bag in zip lock freezer bags... better yet, don't bring phones.
* it is flammable... don't get stupid. Take care not to get it in between the display and glass if this possible to do as it would leave a residue.
Use your best judgment.
