Dropped top half in water

Well, my MT4G was dropped in a cup of tea (long story) and the top half was submerged in water for maybe 4-6 seconds. I immediately pulled the battery, removed the micro-SD and SIM cards and put the phone in rice. The screen looked like there was water in it. At first I thought it was inside the screen protector, but it turns out it wasn't. How long should I leave it in the rice? Also, has anyone else had their MT4G fall in water? If so, did it function after drying it?

at LEAST 24 hours. Water isn't what causes issues with phones, its the corrosion and shorts it causes that are the problem.

i dropped my mt3g in a half full 5gal bucket of clean water. it ruined the battery, but after leaving it in a bag of rice for about 24hrs it was fully functional again. not sure how that will translate to the mt4g, but that's my history with water & rice. good luck

It seems like it wasn't damaged too bad considering everyone else whose dropped it have either submerged it or had it wet for a long time. Anyways, I hope it still works.

I dropped mine in a clean toilet with the led flashlight on at 330 am.lol it was pretty funny to see a toilet lit up like that! I pulled the battery asap and It was in rice 36 hours and all was good it did have a little discoloration in the screen first run but it cleared up after a few hours on. Hope you get as lucky as I did.

Thats it exactly. Considering what the phone was dropped in was not plain water, he will have major issues. I doubt just drying it out is enough. If the tea had sugar in it, the problem is worse still. The compounds in tea and sugar will be conductive and corrosive, that is bad, even if it was fully dry there will be problems.
You need to seriously clean the device now. Use 100% pure isopropyl alcohol or pure denatured alcohol to clean electronics. And it would be best to take apart the outside case and expose the circuits. Use a spray bottle and spray it down until it comes clean. The alcohol will clean the tea out and it drives off the water. heck, you could dunk the phone in it a few times even. Just let the alcohol dry for several hours in a warm spot, air movement will help as well. Alcohol is perfectly safe for electronics, it is all that I use when doing repairs. Isopropyl is what is used in rubbing alcohol, but that is not 100% isopropyl so do not use that.
First advice though, before breaking into the phone to clean it, check the water exposure sticker. If it is not discolored meaning that it was exposed to water, clean the outside of the phone with alcohol well, and send it in for warranty if it does not work.
Never really understood how the rice thing works, seems if it did draw out the water, you could cook rice by leaving it out on a humid day. Maybe in the closed system inside a sealed container, it evens out the humidity level and allows the water to evaporate naturally more quickly.

It was just water that had a teabag in it. No sugar. Also, where is the water exposure sticker?

Bottom half lol under battery it should be a white circle not red at all. Its possible it has an internal one but I'm not tearing in to mine to find out

I just took the phone out real quick to look at it, and it's been about 22 hours. I didn't put the battery in yet, but the screen still looks like there is water in it. In the top left corner, it looks like there is water there. If it's still the same after 22 hours, how much longer should I leave it in there? Also, the water indicator looks like it's white. I'll try and post some pictures later.

How long had it been brewing? If it was still mostly clear, you should be ok, but if not the compounds in the tea can cause issues.
With that much water, it could take a long time. The longer the water sits in the phone the worse it gets. Standing water like that is never good.

forgive my ignorance. but why 4-6 secs?
usually when a phone drops into water i would expect it to be pulled out within 1-2 secs..lol
but good luck, hope all turns out good for you

I turned the phone on and it works fine except for the screen which still has water in it. Here are some pics:

Any ideas on how to get it out? The rice doesn't seem to be taking the water out of the screen because it looks exactly the same as about 30 hours ago.

Mine had discoloration but not actual water as yours does. After I left it on and charging with stay awake checked it dried it out, after about 2 hours. Its best though to let it dry while OFF.

You may need to crack it open, water needs exposure to evaporate efficiently. If your cracking it open, it wouldnt hurt to clean it with isopropyl like I mentioned.
If worse comes to pass, get insurance on your plan, and make a claim.

I managed to get the water out of the screen but it left a water spot where it was. Is there any way to get that off without opening the phone?

Just wanted to share my experience:
Woke up much earlier than usual due to work, and dropped the phone in the toilet. I grabbed it out within a couple seconds, pulled out the battery, dried everything as much as I could with kleenex, used a vaccuum to get as much out as I could, then tossed it in a zip locked bag full of rice for 48 hrs.
Phone worked as normal afterwards. $$ saved!

on my first mytouch, I actually wanted to see how it would react to water. turned it on and left it in a sink full of cold water for about 15 mins. took it out and gave it a good shake to get most of the water out. then I just set it out on my desk, no rice or anything. after 2 full days, I put the battery back in and it booted back up just fine, no discoloration or water in the screen...no hiccups in performance or anything. I wouldnt recommend anyone to just go throw their phone in some water, but this is what I experienced

Z2 camera scratches easily

I have my Z2 so 2months and I'm beggining to see some scratches on the rear camera in direct light. There are no problems in making pictures tho. I'm really careful with my device too.
FIX:

Put a tiny drop of water on the lens and gently rub the corner of a credit card onto the lens. I had the same issue with my HTC One M8 lens and performed the same method and its crystal clear now.

I've got them too, mine is 2 months old.

6 months old and did not have a single scratch. That is anti ultraviolet coating. Wipe it out and everything is fine.

Its been there for an purpose.No hard feelings,but when its gone i doubt everything will be like it was there when its wiped out. I have the same issue and rly don't know how did that happened when i bought a back screen protector + case the same day.. I hope your words are true tho and this wont affect the lense. Havent noticed difference in the pictures in daylight tho.

Some people use toothpaste and it works good but..
Like someone said earlier it's there for a purpose. It's the anti-reflective coating and when you will rub it off the quality of photos will deteriorate in direct light, no question about that. It won't be that much visible but you should know about that before you do it, not after.

Any way sony could fix that for us? Or someone tried to give his Z2 to sony centre and get an replacement camera glass? (btw the picture u gave is zoomed only not taken with/without ar coating. And about cleaning it..im too afraid that i could scratch the glass itself.
Just read abit for that problem.It occurs to every phone with AR coating camera glass and the problem is that the lens is exposed to excessive amount of sun light of heat,the AR coating will start cracking itself cos of the hight temperature.Lots of users reproted that the AR coating started to flake off and their pictures began to get blurry.Cleaning the lense glass with alcohol will do the job and bring the sharpness to your pictures,but will affect the light influence in the pics. I will personaly try giving my phone for repair/replacement.

Sony doesn't want to repair this (they say it's a user fault - bad usage of phone) just like HTC (One M8 have a much bigger issue with this coating on One M8).
To repair this you need to replace back panel, lens cover is integrated.

That's not entirely true. Every good camera lenses have this coating. After long usage it may start to flake if it's poor quality. Another reason may be bad treating with chemicals.
In smartphone department quality of this coating is not as good (in most cases whole smartphone is cheaper than proper camera lenses). When there is some problem at manufacturing stage (like in One M8) or just very poor quality control (Z, Z1, Z2, compacts all have this problem) we see that this coating starts to flake very early. Sony and HTC should repair this, but they can say that you used chemicals cleaning your phone and destroyed it yourself and you can't do much about it.
Heat from excessive amount of sun light can be a reason too, but mostly in sunglasses left in direct sunlight for too long. In camera lenses (standalone or smartphone) destroyed coating is a result of bad manufacturing and bad usage, MOSTLY - not always of course.

I guess the only thing i can do is to wipe it off and deal with it than.No guarantee that if i get an replacement (which wont happen) the ar coaing wont flake off again. :silly: Strange is that i have an ZR as well - dived in salt water and stuff with it and the coating its perfectly fine..

I had the exact issue on my Z tho.

Ok.Just to share with you guys.Ive removed the AR coating (or what was left of it) and the glass is crystal clear now , as the pictures i made from now on.They are sharp without distorsion and noise or blury.It helped me alot.The only disatvantage is that if direct sunlight fell on an object that you want to snap.It will get abit blurry,shiny.But there is a fix for that too.If you want to focus that object,just zoom abit,step closer to it,or fix the exposure of the picture before taking it.These things will do the job perfectly.Cheers.

I used a dab of toothpaste and a cotton swab. Took the scratched and blurry coating off without damaging the camera lens. Rinse afterward. I would advise against using any harsh chemicals.

Sony does repair it! Got my back panel replaced with a new one, got my phone today only, it's as good as new!
I had the same problem, took it to the service centre, they submitted it and gave back an almost new (with back panel replaced) phone in just 6 days. So please don't reach any conclusion before you try the proper way.
Thanks.

In Poland Sony doesn't repair it and it didn't repair in Z or Z1 as well. In most cases at forums people have problems with warranty repair this too so maybe you are the chosen one?

Had the same thing & had some kind of stains that i think were caused by water, even ruined the quality in daylight :\ fixed it by rubbing shampoo on the lens "sounds silly but it actually worked "

The same for me and maybe worse.. BUT THEY DISAPPEARED AFTER FEW MONTHS LATER!!

Issues after using phone under water for less than 2 minutes

Hi guys,
I received my GS7Edge right before a trip to Hawaii so I took it with me. For the first 4 days it was all great,
i set up Samsung pay and worked at every place I used it without issues. The car rental I got had Android Auto and it worked amazingly, even when we had no signal in certain areas. But on Saturday morning I tried to take a cardboard pic under water and that's when trouble started.
At first it was going a little bit crazy, thinking I was touching the back button or the home button while under water and I wasn't able to take the picture so I took it out.
once out of the water I tried to turn the phone off but the power button was unresponsive. So I kept trying (around 15-20 times within 2-3 minutes) until I was able to finally turn it off. and of course I started getting worried...
When I got back to the car I plugged to the car and now Android Auto wont work. so I restart the phone again and now I get this message saying that there was an error with Samsung Pay and asked me if I wanted to send a report to the developers. The email said something like this:
"SamsungPay Exception Report[3/6, 20:44]
etc, etc etc...
The information you provide will strictly be used for troubleshooting purposes only, in an effort to improve Samsung Pay. We appreciate the time you have taken to help us isolate your issue. To help us improve your user experience, please take a moment to fill in the table below:
etc etc etc...
FATAL EXCEPTION: main
Process:com.samsung.android.spay, PID:****
java.lang.NullPointerException: Attempt to invoke virtual method 'int android.content.Ur*********r.match(android.net.Uri)' on a null object reference
//////////////////// Spay Stack Trace ////////////////////
etc, etc etc"
So after seeing that error I checked my Samsung Pay acct and all my cards are deleted.
I also noticed that the phone stopped charging. So I just turned the phone off and used my LG V10 instead (that I luckily took to the trip... just in case).
So yesterday I turned the phone on again for few moments late at night and I got the message about the Samsung pay error mentioned above and also another one saying that moisture was detected in the USB port. but when I plugged the charger it was charging normal, however, no Android Auto.
Sorry for the long post, I was just trying not to leave details behind. But after seeing other videos in YouTube about how good the SGS7Edge handles water, its disappointing that mine with a little bit of water went coo-coo
Should I send it back to T mobile or should I just wait and maybe once it dries completely (idk how long that would take) it will work like its first 4 days.
Thanks!

Wow, didn't expect that.
Wait a day, if it doesn't work, send it back.

Hawaii.... Pool water or ocean water?

ocean water is bad for electric devices, even "water proof" ones.

it was ocean water. i used the xperia z4 in ocean water multiple times without issues so i thought this time wouldnt be a problem:crying::crying:

I don't understand why people are so eager to dump their s7 or s7 edge In the water. It's water resistant, not water proof. It was given that to save you're phone from minor accidents, not meant to go full blown scuba diving. I know I'm exaggerating a bit, but still

I think that phone is done even if it did come back to life for now. Besides the moisture present issue, if it was compromised and had water intrusion especially sea water, the corrosion is just starting.

stick the phone in the rice for a couple of hours and rice will absorb the water from the phone

Might even consider washing it off with tap water to get the salt out, then stick it in rice. Salt water even eats boat motors over time. Cell phones, water resistant or not, don't stand a chance.

I think that some really sound advice. Salt water is highly corrosive

I think your s7 may be defective, IP68 means complete submersible in water. I know salt water is worserererer than fresh water, but not when talking in minutes, its worse over hours due to corrosion.
im no expert but my moto defy never died with all the beach swimming i have exposed it to, it later died a day after, from lying in a pool of cold rain water over night inside a camping tent, mostly bcos it did not have internal waterproof coating and you can clearly see you condensation.
I will definitely be testing the s7e at the beach and in rivers and will update if it dies

salt water? then you are f*cked.. never put a phone in salt water.

S7 don't have waterproof coating though. It only have seal prevent water from going inside.
Salt water is quite corrosive whether you put it in for a minute or hour
Ocean water also contain not only salt water but other chemical as well even in small amount.

none of these geniuses know what they are talking about. Give it a few days to dry out, due a factory reset and off you go. It is IP68.

so where is it confirmed the s7 is not waterproofed from the inside out? as in, there is no nano type coating? i have the impression it was designed with multiple waterproofing layers from the inside out... anyways, the IP rating is an international rating and I'm sure samy have made the s7 to meet those standards.
guess will just have to wait and see

S7 Edge NOT water resistant - Overview/Recent Tasks button stuck "pressed"

After a short dip in water well within the IP68 specs of the Edge, the phone died and I couldn't boot it for a few days. Definitely not water resistant, let alone waterproof. After 5 days, I pressed Volume Down + Home + Power and it finally booted, with the Home button not registering fingerprints. A day later, that problem fixed itself, but the Overview / Recents button keeps being "stuck" (as if I was pressing it all the time), so it triggers the context menu in any app that supports that (e.g. in Google Maps is brings up the side drawer menu, in Chrome it brings up the overflow menu) every 3 seconds, making the phone basically impossible to use.
Any ideas on how to fix this? I bought the phone on eBay, so I doubt Samsung will honor the warranty.
More about the water encounter: 10-15 minutes in my swim trunks pocket, pool with slightly salty water, depth of ~2-3ft of depth - well within the IP68 specs of the Edge (1.5 meters for 30 minutes).

Salt water. Corrosive, a good conductor and if the water evaporated, you can get salt deposits which can block anything and everything.
I've just read Samsung's literature and it warns specifically against salt water, and you should try and rinse it out with fresh water immediately after exposure to salt water.
Afraid this is your fault, not Samsung's.

Cool story bro.

I've seen Xperia Z2s get water damage easily enough. There is no such thing as a fully waterproof phone. Water resistant. Samsung's adverts show people in the Rain not swimming with their phones. Over time the seals won't be as fresh as they were when you first bought your phone. All that changing temperature and flexing.

Water under the Overview button
After a closer look, here's what probably happened: water entered around the Home/fingerprint button under the Overview button, and it intermittently triggers it.
Any idea how to fix it? So far I've tried leaving the phone overnight in a ziplock back with ~1 ounce of silica gel, then leaving the Home button area on a running vacuum cleaner for 15 minutes. The water is still there just as before.

Hairdryer. Be careful to not make it too hot, but heating it up with a hairdryer will dry it out.

I aimed a hairdryer on "warm" at the bottom of the phone for about 15 minutes, but that didn't help. The overview button still triggers randomly.
This teardown video suggests it's impossible to get to the buttons without damaging the screen and this other video does show how the screen gets damaged.

dude be patient 15 minutes of everything isnt going to help,that silica thingy should be done a few days the same goes for rice, the hairdryer method should be done like an hour at a minimun,all the components have to heat up not just the outside of the phone...be patient it will work

Phone off, place on radiator on top of a soft cloth. Not for too long though.

You bought it second hand, who knows what the phone had been through had that point. Maybe the previous owner had a screen replacement, maybe the home button was somehow faulty. Doesnt say anything about the water resistance of a phone bought new.

From the image it looks dry and that is salt residue correct?
If its the salt water thats damaged the buttons, my best guess would be to submerge the device in fresh water and attempt to have the salt cleared.
then dry and see if its any different.
I have submerged in the bath and used my device many times in the bath and never had a issue.
I have event split a stupid amount of coke (Not the powder substance chaps) and various alcohols. Device still works perfectly.
The only issue i experienced was after coke / beer was split on the device quite badly the volume buttons got stuck a bit, but after a long shower with the phone it was as good as new again

I will agree that it takes time. Unless the internal electronics are damaged, the hairdryer should dry out the phone and solve your problem but the area has to heat up substantially.

Tried hairdryer for 1 hour and a half, nothing

I bought it new from eBay, it certainly looked absolutely new, and was waterproof for 9 months in far worse conditions than in that pool.

I will agree that it takes time. Unless the internal electronics are damaged, the hairdryer should dry out the phone and solve your problem but the area has to heat up substantially.

Left he hairdryer on warm pointed at the bottom of the phone, about 20 centimeters away, for about an hour and a half. It's also been a week... I no longer see that residue at the edge of the Overview button, but it still triggers several times a minute.

I had severe water damage in my s4 while kayak fishing. I just pulled the battery out and had a desk lamp with a 60watt bulb in it turned on hovering about 6-8 inches away. Flipped the phone over every 30-45 minutes while I did other stuff on my PC. Took about half a day or so but it work perfectly. Phone is back to normal. It's now just a back up phone since I now have the s7 edge.

You shall try disabling the recent touch button for a while. The device needs to be rooted to do this. Meanwhile you can have the soft buttons at the bottom like nexus and moto phones using some apps out there. Few Edge apps also have the back, home and recents soft buttons.
Leaving it disabled for some days may fix it. May be you can give a try!

No need for root - the Buttons Remapper app worked just fine to disable the task switcher button.

Nope, no luck. 6+ weeks later, still not fixed. The task switcher button presses itself randomly and very often.

The characteristics of that IP certification is that there is plain water used and salt (sea) as well chlorine (pool) do not apply as well as anything else there might be with the water. Especially those two mentioned ones are rather aggressive materials.
The problem is whatever happens and if you even get your phone running afterwards there will be damage to your phone which may bring up faulty behavior sooner or later (corrosion is the most common reason).
And the disadvantage of the certification is as well that as difficult as you get water in the more difficult is it to even get it out. Pretty much there are only two ways - flowing downwards or steaming upwards. Any edge, corner, obstacle will keep some portion of it inside.
In your case you can try to check with Samsung (it doesn't hurt you) if they can help you. As long as the phone is designed for your region and the eFuse is not triggered (Knox Warranty must be 0x0) they will have a look. The further outcome will be depending on what they discover (if they find any residues they may refuse, either).
Aside of that you can always check with a qualified repair center and ask for a price estimation.
Btw compared to Xperias the S7 keeps the water really good out (my experience).

Any ideas on how to fix this? I bought the phone on eBay, so I doubt Samsung will honor the warranty.
More about the water encounter: 10-15 minutes in my swim trunks pocket, pool with slightly salty water, depth of ~2-3ft of depth - well within the IP68 specs of the Edge (1.5 meters for 30 minutes).

I have 'repaired' a number of water damaged smartphones (2x iPhone and 1x Galaxy Note 4) by putting them in an electric oven at 70'c for 20 minutes (powered off) then allow to cool for another 20 minutes.
If that is too extreme for you, putting your handset inside a bag totally covered on all sides with dry uncooked white rice can do the same job but takes days or even weeks to do the same job as an oven at 70'C
However this works well for clean water damage... not tested with sea or swimming pool water.

XZ2P camera lens cover scratched

Hi,
Basically the camera lens cover of my XZ2P is getting scratched more and more (idk why). My question is that are the scratches on the glass/plastic cover or is it on a coating covering the glass/plastic. If the latter is true, that would mean, I could potentially remove the coating and the camera cover would be unscratched, right?
Going to a service center is not an option as in my country they do not offer assistance with the XZ2P.
Please help.
Thank you

Hello,
If your scratch looks like this: https://i.redd.it/os2d7mzo2o621.jpg then is the coating. My camera started scratching out of the blue, i tought it is the glass but it was the coating.

Thanks for your reply! You helped me out a lot. Yes, it is the same thing only worse. What I do not understand is that even though the coating is getting messed up, the pictures are still coming out decent/normal. I am however concerned that if the coating gets totally ruined, the pictures will be messed up. I have seen some videos where people have taken their coatings off using spirits/alcohol but I am still unsure if I should do this since there will be no protection left!
Thanks again bro!

Mine is all gone and the picure quality does not seem to be afected. Did some tests in low-light/outside light/artificial light and the pictures are just fine. It is strange that 1000 usd phone is scratching so easy..

In Poland it's look like this:
My Xperia XZ2 Premium problem start with two small spot. Now it is one big blur. I send the phone to Sony's authorized service. I received the following information:

I'm having this exact same issue with my XZ2P. Delamination of the camera glass coating. My issue occurred within 3-4 months of purchase. I have been without the phone for 2-3 months now while I argue with Sony UK and SBE (the authorised repair centre) about the fact that it's a defective materials issue and not physical damage as they keep claiming to avoid a warranty repair. They continue to refuse their contractual warranty obligations. They are demanding I pay an inspection fee to have it returned to me without the issue even repaired.
So frustrating that Sony expect to charge so much for a flagship device like this but not stand by and repair it when it's defective within months of purchase.
I've always looked after the phone, it's been in a case since opening the box and never dropped or had anything near the camera glass to cause a scratch. There's not a scratch on the thing. Just this frustrating blemish on the camera glass from the defective and delaminating coating.
No wonder Sony had to retrench from the world market with poor quality from a flagship device like this followed up with no support what so ever.

Thankfully there is a decent support staff member on the Sony mobile support forums that was finally able to resolve this dispute for me when multiple support staff at SBE UK and Sony UK refused to listen. Phone repaired under warranty and I'm now awaiting it's return.

Unbelievable but also not surprising, only had my XZ2 Premium back for a month post camera glass coating repair, and it’s already delaminating on the replacement housing. What a joke! How did Sony let such a bad design on an expensive flagship get through R&D? I’m glad I didn’t have to pay for the repair given this second materials failure in a short period of time. I’ll not be bothering with another warranty repair given the debacle last time. I’ll be stripping the coating off like others have done once it gets bad enough. So disappointed with Sony.

So the camera glass coating wore on my XZ2 Premium so badly in just a few months that the camera couldn't take a photo without being blurry with a white haze. I tried stripping the coating off with rubbing alcohol but it made the haze worse after completely removing the top layers. However I can confirm that polishing the camera glass with a fine cerium oxide compound removes all of the faulty coatings and binding layers from the glass so it's clear again. My XZ2 Premium can now thankfully take decent photos. It's a bit ridiculous that I had to go to such an extent to repair the phone myself to make the camera actually functional again. I certainly wasn't interested in fighting with Sony UK over a second warranty claim for such a poorly manufactured flagship device.

Hi,
This has happened to my XZ2 Premium and I'm not sure what to do. I have experienced Sony's/SBE's warranty repair process on a previous device and it was not a good experience so reluctant to send them my phone.
Can I ask how you used the cerium oxide? Does it need to be used with a small polishing wheel on something like a Dremel?
Many thanks in advance.

I guess you could contact the relevant Sony support email for your world region and explain the defect and the issues that other users have faced and see if they can guarantee a repair under warranty for you device and push the issue prior to sending it in for repair.
Failing that, I used the cerium oxide with a Drexel and felt polishing disk. I purchased carpro ceriglass as it’s a gentle formula you can use by hand on car windscreens. It did a good job, very minor surface swirls can be seen under the right light so I could go one step further with and ultra fine cerium oxide compound but the camera looks and works just fine. To protect the metal trim and glass back of the phone, I covered it with masking tape and used a clean sharp blade to cut out the hole around the camera glass before polishing. Makes clean up easier also. You need to keep working it a little bit at a time and keep the slurry wet and reapply as needed until you reach the result you’re after.
You can also up a replacement oem back housing from witrigs for a reasonable price. It’s a fairly straightforward swap out if you watch their repair videos, you just need to purchase the finger scanner sticker and lcd supporting frame sticker to put the phone back together properly with new adhesives.

Hi,
Thanks for your reply.
I have submitted photos of the defect on my device to Sony UK support and awaiting their response.
Failing that I'll have to consider the cerium oxide option as replacement back covers in the uk are nearly £100!
Many thanks

This happened to mine, and it was accepted for repair under the warranty.
