I'm having three problems with my android phone (HTC Explorer): firstly when I try to open Google Play I keep getting the "No Connection" message; secondly in the Accounts and Sync area I keep getting the "Sync is currently experiencing problems. It will be back shortly" message; and thirdly when I try to open Facebook on my phone I keep getting a "Lost Connection" message. My sister is having a similar problem with Google Play on her phone and when she tries to open Facebook on it, it comes partly up with the arrow circling as through it's still loading but goes no further. I've tried clearing Google Play's cache and deleting it's data (on my phone) as per other forums' suggestions and I've checked the date and time but these are both correct. What else can I try?
