Verizon sent me a refurbished phone because the original one I purchased had a screen defect. Ever since I received the refurbished phone, it randomly rebooted about once per day. I wiped the cached, rebooted, etc. Nothing helped.
Now it's about 4 months later and it's much worse. The phone reboots about 5 times per day now, so I'm finally reaching out for help.
I have a feeling it might occur when it switches from WiFi to 4G, but I can't be certain.
What can I do next to troubleshoot it? Could it be a hardware issue?
(not sure if this is related, but sometimes I cannot turn on WiFi and Bluetooth. I tap the button to turn it on, it switches to the on purchase for a brief moment and then immediately reverts back to off without turning blue. The fix this by restarting the device)
