I shipped my HTC One in to the warranty center to get the pink tint repaired but before that I called and the guy instructed me on how to back up my contacts. I did it as he said and I specifically remember my google contacts have like 128 people or something and my sim had like 30. I plugged the sim into my old iphone 4s and I noticed that I didn't have some contacts and when I went to google contacts I saw that I only had around 50. My question is, what happened to my contacts? Is it because I went from Android to iPhone so it won't show up on iPhone but will on Android? I have no idea really. My only other question is would they factory reset my phone?
