So when i try to add a payment metod on google play it just crashes.I tried restarting my phone and deleating and making another google account.If it also help my phone is a samsung galaxy note 2.
Is this a new phone, or one you've been using?
What country do you reside? Is Google Play Store available where you reside?
Are you on a stock or custom rom?
What version of Android are you on?
I would first make sure you are using the most recent version of Google Play Services. If this doesn't work, a factory reset may be needed. Before resetting, make sure you back up any important data. Keep us posted.
