Have a Galaxy S5. As of early July I've been unable to send calls without it getting dropped. People who call are sent directly to voicemail. To top it off, I can't retrieve any voicemails, unable to log in. I've tried restarting the phone but that doesn't help. Tried deleting or stopping apps & deleting or transferring unneeded photos.
The only thing my phone is good for anymore is sending and receiving texts, though sometimes that is hard because the "send" is "pending." But that's another matter.
Any ideas or should I send a help ticket? I'm ready to switch, both the phones & carrier.
