Oil spilled on phone,now I can't make calls
So two todays ago I accidentally spilled hair oil in my purse where my phone was. I was in class so all I could really do was take it out of its outter box and wipe it. It seemend to work fine so I didn't think nothing of it.later that day I tried making a phone call and all I could hear was my own echo when I use my head phones I can also hear my echo. The next day I opened the back and found a bit of oil that I wiped away and put it on oil all night,it still doesn't work and I can only be heard when making calls if my it is on speaker. What should I do I feel that the more time that passes the more my phones being damaged (if there is still unvisible oil) in phone.
Is this a good question?
