How can I fix my phone?

Hi Becky, that’s quite a series of unfortunate events. The lines in the LCD and it turning off after being dropped in water is not good. There is a chance the battery just shorted and that’s all it needs, but sounds to me like the LCD went out and the logic board shorted out in which case the phone is dead. Best thing you can do when a phone drops in water is turn it off (remove battery if possible) and take it to a repair shop immediately so it can be dried out. Rice does the same as leaving it out in the open.
