My phone gets disconnected most games. If I don't get disconnected,there is terrible lag. Is this just a problem with my type of phone? Or does it happen to more people?

I get crashes and freezes on galaxy note 10.1 WiFi running android 5.1 crashes taking me back to the home screen of the note. Freezes being that the note freezes entirely. This usually is happening when I. In a tank just as I fire on either occasions. Maybe its just happening on Samsung devices? On the latest dogfight update.

It's happening on my kindle fire...that or internet connection issues

If you are having issues with an update, un-install the game, re-boot your device, then re-install it. To solve connection issues over wifi, turn off your router for around 30 seconds then turn it back on.

If you are playing over 3G or 4G connection, use a cookie cleaner app to free up your device memory. I recommend an app called CCleaner, it is available on most platforms and is easy to use and a free version is available. It also has a cleaner in the menu which will get rid of parts of old files that have been left after un-installing programs in the past. Look in the menu for the registry cleaner and run it. You will be surprised how many registry issues you will be able to sort out in the space of a month! This will free up available processor memory making your device more efficient and faster. I find that CCleaner can really help get your device back up to full speed, no matter what platform you are on or what connection you use.
