dropped my moto g7 and I put it in rice for a day

Hi,

Since you placed it in rice, I’m assuming that it was dropped into water, is this correct?

If so, the liquid causes corrosion and 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 continues until it has been cleaned properly

Rice is good to eat but does nothing to fix the problems caused by corrosion.

Don't Put Your Device in Rice. Here's Why...

First do not try to charge or to turn on your phone and then 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 99%+ (available from electronics parts stores) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that in general, 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. You will also have to remove any shields that are covering the components as water may have got under them as well.

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

Here's a link to a video which shows how to dis-assemble your phone, which may be of some help

If this process seems too daunting, take your phone to a reputable, professional mobile phone repair service experienced in liquid damage repair and ask for a quote for a repair.

If you decide to do this, do it sooner than later.
