My Galaxy S3 was in my jeans pocket when I leaned over to pick something up that I dropped under the table. A few minutes later, when I took out my phone, I saw a long diagonal crack from one side of the phone, straight through the middle of the screen area and all the way to the further edge of the phone. Thankfully everything still works.
My question is, is there anything I should do about it - i.e. replace the screen, layer it with transparent tape - or just leave it and everything will be fine (i.e. it can't get worse)?
