- Through standard settings, if you can boot Android.

- We simultaneously press the power, volume up and menu buttons.
- When a dark window appears, use the volume buttons to go down to the “hard reset” option and perform a reset.
Checking charging capability
When the device does not respond to turning on after charging, this may indicate loose contacts or a malfunction of the charger. To check it, just do any of the following:
- Check the memory on another smartphone. If it starts charging, then the problem is in your Samsung and you need to pay attention to the contacts inside the micro USB connector.

The Samsung Galaxy S7 and Galaxy S7 Edge are waterproof, but after spending your hard-earned money, you shouldn't be surprised if submerging these devices in water affects their core functionality.
As we already know, Samsung introduced these two smartphones during the Mobile World Congress 2016 and announced that they are IP68 certified, which means they are completely dust-proof and protected from continuous immersion in water.
The Korean manufacturer also shared information that the Galaxy S7 and S7 Edge can be taken anywhere: in the shower, in the rain or in the pool (swim with these devices at a depth of up to 1.5 m for 30 minutes). In addition, it was stated that Samsung has done a great job of sealing the internal components of smartphones, despite exposed headphone jacks and micro USB ports.
Without a doubt, the dust and water resistance of the new Samsung flagships will definitely attract many customers who like to take their phones outside or take underwater photos.
However, it seems that the Galaxy S7 Edge will not charge if this smartphone is set to USB port moisture is present.
“I took an underwater photo this morning and placed the S7 Edge on the table. Four hours later, I plugged this smartphone into a wall outlet via a fast charger, and the display showed the error message “Moisture detected in the charging port” and the phone would not charge,” complained the owner of a Galaxy S7 Edge on the XDA Developers forum.
This person was advised by other visitors to the above forum to dry the smartphone with a hair dryer or put it in a rice bag to remove moisture, which is what the owner of the S7 Edge did. However, the device still did not want to charge.
“The behavior of the smartphone in the first 30 seconds after immersing it in water is very annoying, and this despite the fact that it has an IP68 protection class. Frankly, searching for a hairdryer or rice bag every time this device gets wet negates that high level of moisture protection,” adds a Galaxy S7 Edge owner.
Some other users also received this message, although it did not appear until about an hour after removing the device from the water, and the phone charged without any problems.
Note that, despite the fact that the Galaxy S7 and Galaxy S7 Edge have IP68 protection, the charging port of these smartphones is not covered, and water can penetrate into it.
Many of us will be interested to know that the charging ports of the above devices have humidity sensors, which can be called a useful addition to Samsung phones. In addition, such sensors protect both the device itself and its owner from damage and short circuits.
Various reports also suggest that the possibilities wireless charging are not affected by the emerging problem of moisture in the charging port. However Galaxy owners S7 and Galaxy S7 Edge are not recommended to be placed on charging mats when wet.
If your phone's battery isn't charging properly, don't think it's just the battery or the charger that's causing the problem. Based on personal experience, the problem and its solution may be much simpler than you think. If your smartphone or tablet is charging poorly or not charging at all, then check out 10 ways to fix these problems.
Why is the device not charging?
Problems arise to varying degrees. Either the phone doesn't want to charge at all when it's connected, or the process is too slow. Here are some solutions for you.1. Poor contact
Very often the metal coating inside the USB port and micro USB has poor contact, either through a manufacturing defect or through wear and tear on the cable.
All you need to do is turn off the device, remove the battery if possible, and clean the contacts inside with something like a needle or toothpick. Do this very carefully and carefully, then insert the battery and connect the charger again. 9 times out of 10, that's all you need to do.
2. Clean the charging port from dust and foreign fibers
Do you keep your phone in your jeans pocket? If so, then fibers could be the culprit: we've lost count of the number of times fibers in our clothing have caused faulty charging.
You can also return the charging connector to normal condition by blowing it with compressed air.
3. Try a different cable
The most fragile part of the charger is the cable. It constantly bends, which can damage it over time.
The easiest way to diagnose a damaged cable is to take another one and see if it works properly with your device. If yes, you know that the original charger wire is faulty. If not, then you need to look for a solution further.
4. Use a different adapter
You have ruled out problems with the cable, then you need to check the functionality of the charging device itself. This is much easier if you can pull the wire out of the adapter. We've encountered many chargers where the USB ports have become worn out due to endless plugging and unplugging of the cable.
Also check the charging/wire functionality on other phones as this will help rule out the possibility that it is a problem with your smartphone. In addition, you must make sure that the outlet is working properly.
5. Remember - safety comes first
Do not charge your device near water or in extremely hot or humid conditions. Do not keep the device connected to the charger for too long. Don't leave it charging overnight when it only needs 2-3 hours. This may cause damage hardware.If you want to replace the charger or its cable, be careful: cheap adapters third party manufacturers quite dangerous. Recently, there have been many cases of mobile phones catching fire due to them.
The video below captured one of these cases:
6. Replace the battery
Life battery does not last forever and after a few years of use it loses its capacity. The more often you charge and discharge it, the sooner it will deteriorate. Of course, if the battery stops working after six months of use, then you need to contact the seller for a warranty.
Some defective batteries can be easily identified by appearance. If it is swollen, then it should be replaced immediately.
7. Charge from the correct source
Charging from a wall outlet will always be faster than from a computer because its USB ports have too little power. Thus, the phone charges much faster from a power outlet.The problem may also be that you are using an adapter from another device, for example, from a Bluetooth headset, which is not intended for your gadget. This adapter does not supply enough current. In the case of the latest high-end smartphones, you may have a device that supports fast charging, but the adapter is not suitable.
8. Update the software or roll back to the previous version
Updates software may degrade battery life mobile phone, especially when the old device gets a fresh one Android version. Newer smartphones and tablets are often optimized for benefits latest version BY.
If this happens to you and you can't find a solution, try rolling back to a previous version. Of course, you can try first full reset, as recommended by manufacturers, so as not to compromise the data on the device due to old version Android.
Likewise, sometimes autonomous operation smartphone can be significantly improved with a fresh update.
9. Try turning it off
Using heavy applications while charging affects the duration of the process. For example, if you are chatting on Skype or playing games, the device will take longer to charge.Therefore, charge the device in the off state or in airplane mode.
