I use chomp sms in which i cant find a don't resend on fail option and and iPhone users messages sometimes arrive delayed i think it is when its a bad signal area but if i restart all of a sudden they pour in . i have a lg g4 which has the issue worse than my droid maxx. Any ideas to fix? I am also on verizon. When this happens people get about 9 repeating messages from me even though i only sent one. On a separate note i love Verizon's web interface for texting which stays logged in even on reboots on windows. I wish it would work on android chrome.
