Within the last two weeks my son's and daughter's screens have cracked on their new S3s. They are college students. My daughter is extremely careful and has had only two phones since middle school without any damage. She did not have a case. My son has a case and still the screen cracked within one month of use. They have had many handheld devices for years without replacements for damage (ipods, phones). Now that I have replaced both phones under the insurance plans from t-mobile should I have them switch them out for a different phone?
