I have a Meizu MX5 and I have an issue with the mobile data connection. Every 5-15 minutes I have a connection blackout. During this blackout I can see the H+ or 4G symbol on the status bar, but I just can’t upload and download data (I cannot even send/receive whatsapp messages, browser not working, can’t play online games etc…). Also, the speed indicator goes down to 0 kb/s. To restore the correct connection I have to disable mobile data and enable it again, otherwise I have to wait about 60/120 seconds and the connection is re-enstablished spontaneously.

Any idea on how to fix this? I’m about to sell the phone due to this problem.
