Hello, I have also had this issue before. I tried every way of rebooting. Have you tried rebooting by holding the power, home and volume down button for a while? If this doesn't work, it's likely your phone has a software issue. You will have to go to an android repair store or your service provider store and they should fix it for free.

Sometimes, whilst your phone is in your pocket, you can accidentally turn on silent mode. However, this is unlikely. The most likely reason is because at the time of them calling you, your device may not have service, therefore the call will not be received yet a 'missed call' notification will appear when it recieves service again. There shouldn't be any particular issue with your phone.

Hi there, 1. You probably shouldn't be shaking your MacBook Pro. 2. It's a 2011 model and quite old, little parts may have disconnected from general use over 4 years. 3. It's most likely the fan. How ever if the laptop does malfunction (software) you should book a Genius Bar appointment at your local Apple Store, as they may just replace it for you. Thanks! Will :)

I've just had the same problem. You simply need to factory reset your iPhone by connecting to iTunes via the USB port on a computer and restoring the phone. If your iPhone's 'Find my iPhone' is enabled you will need to use the steps below. (This method resets your iPhone instantly as long as you have it charged) "1. Go to the iCloud website. 2. Log in and click 'Find my iPhone'. 3. Click the ALL DEVICES drop-down and select your broken device. 4. Click the 'Erase iPhone' option." The Apple logo will appear on your iPhone's screen, and then it will install the basic software. Thanks :)
