Screen won't turn off - Android Q&A, Help & Troubleshooting

I have an ASUS Zenfone 4 (ZE554KL), but I don't think that matters.
Recently my phone came into contact with a bit of water, but I quickly dried it off. After a few minutes I got a notification that the charging port was hotter than normal; I imagined that maybe some water was still in it and causing problems, so I shut off my phone to put it on rice overnight, but as soon as it turned off it turned back on, and now the screen won't stay off anymore. Every time I press the power button to turn off the screen it immediately comes back on.
I booted into TWRP to re-flash my phone (yeah I was out of options), and while in TWRP, the screen was able to turn off completely, so there's definitely something I can do software-wise. Any ideas?
Also: while in TWRP with the screen off, my battery still drained quicker than normal, so maybe the CPU is always awake aswell? God damn.

Must be some water/moisture shorting a contact somewhere inside. It may have moved or evaporated as it got hotter when you used TWRP.
This can be very tricky, especially with new sealed phones. Hopefully you can get back off a can of air could blow it away & then let it dry out 100%. Else turn off & try putting phone in a sealed container with rice (or the moisture absorbing desiccant if you can buy it) for a week ... or two. (turning on & warming it up & putting it back in for every few days might help)

Hmm I don't think I can open this phone, but I'll google it. My phone already spend 5 days on rice, no difference yet; should I keep it more time?

[Q] Random turn offs.

Helpp!!!!!!!
Dropped my xperia mini and it got very slightly wet.
It didn't turn on when i tried.
I took out the battery, wiped it and put it back in.
Then it booted normally. After a while it shut down.
And it didn't turn on. Then I started charging it after about 15 min of not responding it turned on. It was charging till 20%. Then when i started using it for a bit turned off. Now waiting for it to turn on.
What should I do?
Should I get new phone with warranty?
Or is there solution?
Thanks in advance.
Had two incidents like this, the first incident shorted out my phone (just one second in the water), the second one I wiped dry, wrapped a piece of cloth around it and put it in a sack of rice to absorb the moisture (googled it).
Moral of the story: Never turn on a wet cellphone immediately (even after wiping it dry) lest you want a shorted out unit.
Dunno if doing the latter will make much difference seeing as you turned it on and charged the unit. If it is still under warranty you can try to have it fixed, just don't mention the water incident (though there is a possibility they might find out even after it's dried, dunno really)

Thanks my friends told me not to turn it on straight after i wiped it so am getting it fixed.

[Q] A situation after using rice on water damaged Vibrant

It happened two days ago,i did the rice thing and left it for 48 hrs,
today i did a test and i figured the following :
when i hold the power bottom,the battery icon appears (as empty) for a second and then disappears, at first it was a loop, right now it does this for one time.
when i connect the phone to a charger,the phone starts the (charging state) and the battery appears to be full,at this stage i hold the power buttom and the phone starts perfectly and smoothley,i dissconnect the phone from the charger and phone is working with no problem and the battery is full as i left it before the water damage situation.
Is it the battery or the phone itself...???
do i have to leave the phone back on the rice for a while..??
'The Rice Thing' Whats that, urban legend?
Rice will not work. It is an urban legend. The back of the phone has to come off, not the battery cover, the phone back (7 screws). Carefully pry around the back of the chrome bezel and remove. Blow it out with canned air (the phone not the back cover). Soak in denatured alcohol for 5 minutes. Blow it out again. Leave it alone in a warm place for 3 days. Put it back together and fire it up. If it does not work you may have shorted a component on the motherboard. If so, sell it on eBay and cut your losses.
Trying to use a phone that has not been dried out properly will ruin it eventually. Even just leaving a charged battery in it will ruin it as well even if it is not on.

Samsung Galaxy S2 - Wont turn on.

Well back again with new problem.
Have just had my phone back after it was repaired only a week ago by samsung; they repaired the software, replaced screen, battery and USB port. Now my unrooted phone, with only usual apps, has again failed on me. Was on the home screen, nothing else running, and it turned itself of. After a minute turned itself back on, held at the Logo, and then turned of again. Now it wont turn on what so ever. Its not got hot, its not got cold, its not been in a room with steam, its been sat in a decent zenus case, in a house with radiators etc on.
I seem rather unlucky with phones, my old Nokia 5800 went into repair 6 times, until I gave up and brought a £10 phone, that I'm having to use again now.
I have tried charging, despite the fact it was still 62% full when the phone went of. I don't do extreme sports with the thing, I barely use the phone, yet it still keeps breaking. Disappointed, because the phones pretty decent, but starting to feel like I don't do well with them.
Rant over.
Update: Just tried after 30 minutes to turn it on. It turned on for about 15 seconds, got into the unlock screen, unlocked, went to the menu screen and it turned itself of. I put the charger straight in, was charged up to 59% anyway, but thought maybe might be battery... But doesn't seem to be.
Wont turn on/Charge again. The phone is fine temp.
What you're describing could be a phone with a drained battery.
So check the battery with a voltmeter and check the charger. One (or both if you're really unlucky) of them could be busted.
Edit: You can check the charger by plugging your phone to your PC and charging it from there. If it works then it's the charger if it doesn't then check the battery.
Is all else fails return the phone to a service center.
Try this-
Take out the battery, then press and hold the ON button for 7-10 seconds (the longer the better). Reinsert the battery, then press ON button to start it. This is a soft reset, and wipes the temporary memory and empties all remaining power in the circuits. This helps on many phones and even laptops that won't start properly or show anything on screen.
If this does not work, try the next step. Again, do as above. But after inserting the battery, do not turn the phone on, but press and hold the ON button and the HOME button at the same time for 7-10 seconds. This is a hard reset, and works best if done after a soft reset. Just be sure the battery has at least some juice in it and isn't empty. If possible, try with another battery if this does not work.
I read earlier about a similar problem and it turned out to be a loose fitting battery. They put some foam or something at the bottom of the battery so that it would stay tight and retain contact.
You could probably test for this by removing the back cover and pushing the battery upwards while powering on.

Thank you very much MichaelAmrs. you saved my Galaxy S2
Awesome Advice
Thanks MichaelAmrs
I have had some serious trouble with my GS2 not working and the latest has been it not turning on. I stuck my battery in the freezer and then did what you suggested and it worked like a charm. Instead of getting it to boot I tried putting it in Download mode and was able to install the Stock ROM on it and hopefully now it will last. But if nothing else at least it is turning on again.
Good luck.

Dropped phone into water, weird battery issue

Hi,
So as the title say, my battery act very weird.
At first, it refused to charge through the charger. Took out battery and waited 10 min, then it charge, until 100%, unplug charger, and it still charging , never stop.
Took out battery again, waited 10 min, put it in, battery charging icon appear on screen with the little yellow triangle inside, cannot turn on phone. Then I plug charger in, now I can turn on the phone, but battery level now show 80% and notification : charging paused, voltage too high.
Could someone help me?
Thanks
P/s: It was happened last night, leave it over night and I can use the phone normally this morning though.

Oh. Good. Lord.
10 min is NOT ENOUGH TIME to let the thing dry after you dropped the whole thing into water. You probably screwed the pooch on this one.
If the phone is dropped in water, most people recommend taking the phone apart and putting all pieces into a bag full of uncooked rice and silica packages for at least a few (preferably up to 5) DAYS before attempting to reconnect battery.
Because you've reattached battery already after less than 1 hour TWICE, I'm betting you have shorted your mainboard beyond all repair.
Water + electronics isn't necessarily the kill factor. Water + electronics + electrical current (connected battery) BEFORE DRY = dead electronics.
You should leave the battery out of the SGS and put both in a bag with much rice or cat litter some days in a bag. No hair dryer or something like this.
It wasn't a good idea to connect the loader and to leave the battery in the mobile.
I have a friend with exactly the same problem, his daughter put the GS2 phone into water and then he put the battery out for ONE night only... now the phone says is charging when it's unplugged and sometimes the "car mode" activates by his own (i don't even know how to activate the car mode on my GS2) ....
we started to think that the problem will stay forever

You got lucky if yours isn't showing any ill effects after such a short dry time. Yours is an exception.
ometimes the "car mode" activates by his own (i don't even know how to activate the car mode on my GS2) ....

Well, i did have the same selfactivates problem like you for few min,It even turn it on after i put the battery in, without any action. But it gone now. The problem is that it keep saying charging and the notification keep pop up. I can overcome it by install AOKP or CM9 Rom which dont have that kind of notification. But still, my concern is how long can it take till it really dead?...

Start looking for a new phone now.
If you already shorted it, it's not going to go away. Electronics don't just heal themselves over time.
A repair shop may be able to replace parts with shorted components, but if many have shorts, it may not be worth it to fix, and may end up being more expensive to fix than to replace.
You should have left the phone to dry atleast for a solid 24 hours in a rice bag!
I put my old Sony Ericsson in the washing machine once (was in a pair of shorts) lol.
Of course I don't expect it to work... but I opened it up and took out battery etc... left it out to dry in the sun for few minutes (making sure it doesn't get too hot), then put in a nice dry place with dehumidifier. After a couple of days it worked again.
Now that is just lucky and it probably wouldn't last for long... but luckily I was going to buy a new phone at the time anyways.
Moral of the story... phones, or any electronics, are not waterproof unless stated that they are. You have to be more careful people... or get something like Invisible Shield.
do you think that the problem will go away if I got a new battery ??

How can you be confused about this? The issue is a short on one of the electronic components in the phone. Probably the mainboard. Getting a new battery won't address that.
Why not bring it in to some service center (or even some night market telephone tech guys) and have them check it out? Then they can tell you what needs replacing or if you're better off getting a new phone.

Possible Irreversible Water Damage?

Water got into my phone(obviously) and I tried turning it on because of water resistance. It didn't respond. So I tried charging it. Tell my why the phone's battery screen flashed? NVM that, I tried the ol' bag full of rice trick. I left it there for about 12 hours. I tried again, and I got into recovery, but with a reddish tint. Well, I tried re-installing my ROM, hoping that it was an easily fixable issue. When the rom was installing, I unplugged my phone, instant power off. And my phone was at 100% before the install. I panicked, and knowing that I had to use my phone soon, I did probably the stupidest move ever, and put it on AN ELECTRIC HEATER. I left it there for 5 minutes, because that heater gets so hot that the air in my whole house is dry after ~30 minutes. Now sometimes when I turn it on, if the charger isn't in, the apps initialize, then power off, other times I get nothing. If I put the charger in, I sometimes get a white-ish triangle with a red thermometer(I'm guessing temperature warning?) and sometimes the battery flashes periodically. Please help, because of family health problems I need to be able to use my phone.
EDIT***: Phone WILL turn on now, condensation on both cameras, and battery temp too low to charge, so now there's a broken thermometer.

This phone is not water resitant. So trying to turn it on, before it dried completely was not that great of an idea. You could still have someone disassemble it, clean the board in alcohol and replace the battery. I think you just overheated the battery and you might have several shorts on your "mainboard". So please stop using it, until someone cleaned the board at least in some isopropanole or even better isoprop in an ultrasonic device. Dont just throw it in completely, but the "mainboard" only.
