Hello to all, I have an HTC ONE X, with Android 4.1.1 (but I had the described below issue also with previous versions of Android 4). For several months now, I have the following issue: Information disappears from my contacts! Peoples' phone numbers disappear (don't sure about other information), while other information, like: what's up and gmail accounts remains. The result is, that I can't call to those contacts (since their phone numbers do no longer exist under their contacts). If I click on such contact, I only can see its what's-up/gmail information (if there is such information). I can't say for sure, but I noticed this issue after installing LOOKOUT (a security application for android). Unfortunately, if I uninstall this application, I can't access my emails anymore, so I had to reinstall it.. It should be mentioned, that: (i) under contacts, all sources are checked (SIM, phone, google, what'sApp etc), and (ii) I didn't hack\crack my OS, I use the original Android which came with the device. I am helpless, and considering buying an iPhone.. Please advice, thank you.
