I have just recently upgraded my LG G Flex d959, service through t-mobile, to Android 4.4 kitkat. Since I performed the upgrade my device doesn't alert me when I get a text message. Most of the time it does, but every so often it is just like it's on silent. Any ideas what the problem may be?
Unfortunately, I don't have a solution, but my Galaxy S4 is doing the same thing after the "upgrade". I can have the phone in my hand when I get a text message so I'm positive there is no notification. I know it's not just a case of me not hearing it.
