Motorola Defy :: Deletes Contacts Randomly / Delete Pictures From Facebook

So I've had this phone for about 5,6 months with different problems over the course of my time with the phone.Was wondering if anyone has had the same problems and if there are any solutions. So first, sometimes my phone will randomly delete contacts from my phone and place them in the "hidden" folder. I haven't hidden them, but I've gotten text from people and be unsure who it is,but then find out it is someone that I know and who has been in my phone.Also, since my contacts are synced with facebook,it will randomly delete the FB picture to my contact so instead of it showing their default picture on facebook in my contacts, it just shows the blank face. In the past it has deleted the picture and will eventually come back after a coule of days or weeks but currently it has deleted multiple of my contacts pictures and has yet to come back. I dont know if I am accidentally hitting something or if there is a way to prevent this but it is aggravating. Also, sometimes if I go to send a text message, say for instance to Sally Sue,I'll click Sally Sue, send the text but then in my messaging folder it does not show the name "Sally Sue" nor does it show their picture, but just the phone number alone as if I texted someone who was not inputed in my contact list.It eventually goes back to showing the name but it still annoying nonetheless.The last issue is with the gps sattelite that will not shut off and for whatever reason prevents me to use facebook on my phone.I've read that this has been an issue with others in the past and tried some of the suggestions people offered.I have uninstalled FB, reinstalled in, callibrated my phone, taken out the battery, turn on/off, etc and nothing works.Under settings in the securty tab, it is always checked next to GPS Satellites on. I will uncheck it, but it never stays that way, it will always go back to being checked and I can never use my FB app as it will open for like 2 seconds then cut out.
