Black Screen with Time & Location Temperature. Unable to use.

Hello!

I have been looking for this information, but I can't see anyone with the same issue.

The day before yesterday I got my phone very wet. Everything except the microphone and speakers worked - inclusive of the screen, headphone jack and power point.

Today, the alarm I set last night worked - but the phone is stuck on a black homescreen. The screen is fully black, but has the time (working) and the location and temperature of what I was last.

I have tried a number of re-boot options, but none are getting me past this screen. I would love to get the files off it before trying a factory reset, but I cannot access the files as I use a Mac and you need to unlock the screen for Android File Transfer to work.

It would be great if someone can either help me to fix this issue, or help me get the files from my phone without the use of Android File Transfer.

Thanks in advance.

Holly

Hi,

As you now know, water and electronics and electricity are not a good mix.

The minerals in the water cause corrosion and the water also provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion process starts immediately and will not stop until it has been thoroughly cleaned away

First do not turn on your phone and then you need to with the phone turned off, remove the battery as soon as possible from the phone to minimize further damage.''

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% or less and is not as effective. If you do check the label to verify the amount

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a link to the Ifixit repair guide(s) for a Huawei P9 that may help you

If this process seems too daunting, take your phone to a reputable, professional mobile phone repair service experienced in water damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
