Yesterday we received an email from one of our customers, confused by the blank screen when he took a dip and the phone fell into the bathtub. Unfortunately his S7 Edge is reclaimed, water-resistance can not work. We told him the solution and sharing it with everyone.

First you need a set of disassembling tool, drying the battery door with a blower until the temperature reach to 45℃~50℃(1521℉~1690℉), then you can separate battery door. The battery door is made of glass, not easy to cause deformation, but the force must be uniform, otherwise may cause broken. The other thing you need to consider is that: Take apart the phone is necessary, or the drop of water will stay in the machine and influence the normal using.

Second, dismantle the screws of battery door, that is easy but not all, we need disconnect Antenna and NFC Chip in case of permeation of vapor. We need to be careful as the material of NFC Chip is electric coil and graphite, if it is crooked, the sensor function of NFC Chip will be effected.

Third, remove the battery carefully and pull down the lines connected to the motherboard which are the main reason for blank screen.

Pay attention: the motherboard is not need to disassemble for the ventilator and the hot wind can blow in.

Then blowing hot wind around the motherboard for 5 minutes, next placing 1 minute, after that blowing cool wind for 3 minutes. That is just one process, to ensure your phone can power on, you’d better blow the motherboard above 20 minutes.

Finally, Connect LCD Flex Ribbon, Insert Battery and Test Starting Up. If everything is ok, you can test other parts, such as camera, WiFi, call, loud speaker, ear speaker and buttons, to ensure whether each part functions well.
