My ATT S4 broke (just went dead and could no longer be started up despite trying different batteries--I hadn't change/flash anything. If I take off the battery and plug it in, on occasion it would show the bootloader for a few seconds but shutdown right after). Anyway, I have a T-Mobile international i9500 version lying around. I installed LineageOS on it and put in my SIM card. Data works (but no LTE because i9500 doesn't support it) and everything is fine, except the time/timezone is off by a few hours and is wonky.
On my ATT S4, I've always enabled using network time and network time zone without issues. I want to use these settings on the T-Mobile version as well for time accuracy and auto-account for daylight savings (does disabling network time and manually choosing the appropriate time zone also auto-account for daylight savings)?
If I enable both network time and time zones, it will most likely result in the time off by a few hours. Even if it's initially correct (which is rarely), it appears to change back to being off by a few hours. I also tried restarting the phone. I wish I'm getting consistent results--only thing that is consistent is that the time/timezone is off.
I'm not sure if this has to do with APN settings and/or ATT SIM card that works with LTE and is now having trouble on a phone that doesn't have LTE.
Any help is much appreciated.
