my galaxy s4 - brand "new" (refurbished from asurion) - loses its data connection whenever it ****ing feels like it. i don't notice it till i send a text and NOTHING will happen until it fails. to fix it i toggle data, or airplane mode, or lose my **** completely and yell at it. this still takes about a minute to kick in after the toggle, and sometimes the phone needs a reboot before it fixes. when it does respond to the fix, it lasts for ten minutes, fifteen minutes, however long it ****ing feels like it, then starts over again.
verizon network, android 4.3, rooted
i imagine this is an issue with the radio. would a rom have different settings for the radio to keep the connection persistent?
any ideas? the phone is practically right out of the box. all i want is a consistently working device (or at least one that just sends sms and mms consistently without issue), and i have literally never had an android phone that did this.
would appreciate any advice
