My iPhone had few issues lately like:
- getting hot when its charging with the USB connected to PC or when playing video songs or movies
- randomly the touch screen gets hung (especially when the phone is in lock state and when you receive a call and to answer when I slide the bar) and only hard reset is needed in order to get around this.
- the safari browser crashes for few sites and luckily nothing happens to iPhone but instead it goes to home screen automatically from browser window (good and bad: good in the sense the crash is limited to application and bad in the sense the Safari is crashing)
Up on contacting Apple customer service (1-800-My-iPhone) they decided to take my iPhone for testing as they thought heat is not permitted. Immediately next day morning I got the Apple Service 8GB iPhone as a lender phone and I shipped my iPhone back to Apple on the same day using the same shipping box. After 3 days I got my original phone back and nothing that Apple was able to fix nor they provided any kind of diagnose information to me to know what kind of tests they performed. Only thing that was mentioned in the letter was:The reported symptom(s) that is not reproducible:789/Unusually Warm Service
And after I got my phone, I kept it for re syncing and for charging. After few hours I noticed that the phone is hot…..not sure what to do at this time. I am still wondering why they did not perform any manual testing on this kind of issues or contacted me back on how to reproduce the issue.
