Ha a security nem gond, akkor google-nak sem:

"What do I do if my device is not certified?
If your device is not certified, we have not ensured basic security features or apps from Google and the Play Store can work as intended. Please keep in mind that your device may not be secure and may not function properly.

We recommend you contact your device manufacturer or retailer to ask for a fully tested, certified device."
