My tips for today: 1.) Always make a backup – save your files to another medium, just to be on the safe side. 2.) The next device you buy could be an outdoor smartphone – drop-proof, waterproof and dustproof. 3.) If your mobile phone comes into contact with water: switch it off, take it apart and place the individual parts in rice. The rice will absorb the last bit of moisture. DO NOT place it on a heater, DO NOT blow-dry it, DO NOT shake it...
