I live in Brisbane, Queensland, where Daylight Saving Time (DST) is not observed, but my Samsung Galaxy phone automatically moved one hour ahead on October 5, 2025 when DST started in other states.
This caused my alarms to go off one hour earlier, and I ended up arriving at work an hour early.
My partner, who uses the same carrier but an iPhone, did not experience this issue.
It seems that the phone incorrectly detected a Sydney or NSW time zone while I was in the Brisbane area (Slacks Creek). Please investigate this as a system or time zone bug affecting users in Queensland.
Device details:
Model: S25 plus
Carrier: Optus
Location: Slacks Creek, QLD
Issue date: 5 Oct 2025
Please treat this as an official complaint and provide a written response or confirmation that the issue will be escalated to the technical department.
Its Optus. The same happened to me despite having location set to Brisbane. I didn't even get my s25 on their plan I purchased this outright and just have a prepaid card in there. Optus are so technically incompetent they can't explain to me why the MyOptus app has one number wrong as the account name, and so they can't fix it. Factory reset fixed it for 1 minute then it refreshes and shows wrong number again. I know I can 'name' it the correct number, but for the first month I owned it I was giving people the wrong phone number. At the time I was renovating, moving and was being told in emails they had tried to call. I Optus really ***.
