Recently i noticed wrong time after restart and the device didn't update it unless it's connected to Wi-Fi. I did some research and found that the device connects to ntp servers via udp 123 port. And most common issues is provider limitations on this port. Asked in provider's support forum and result is that is set some limitations and probably will experience issues with it. So for know solution is to find why my gt-i9505 forgets time after every restart? I own and HTC Desire Z (Vision/G2) as work phone without data plan but it keeps time correct. Both running CM11 (4.4.2 on DZ, and 4.4.4 on S4). Tried to uncheck "Automatic date & time" but isn't helping. Any ideas?
Just a guess - kernel or hardware issue. Maybe it is worth to flash newer or different kernel.
Here is some thread http://forum.xda-developers.com/show....php?t=1881827
Have you tried factory reset after problem occurred. I have searched in Google and there are lot of phones experiencing the same problem.
One says it is CWM problem (?strange), some do a factory reset, some re-flash firmware... So, start with most acceptable to you.
