My Samsung Galaxy Note 4, keeps restarting. Yes, I called Sprint in the Philippines and yes I called several times and yes I aked for supervisors and level 2 and 3 tech support. Yes, I went to Best Buy, they did a system upgrade and update. Yes, I have Ins. BB said I still have to pay $150 and additional shipping cost. (I didn't see it in the contract, its mixed in with other mumbo jumbo 😢) Yes, I removed the battery, soft and hard reset.Removed some stuff, cleaned cache, ran all anti-viruses, I keep them up to date. Help me?
