I was online chatting with ATT for 2 hrs yesterday trying to get a manually pushed OTA update for Android 10 installed on my S10. Nothing seemed to work. Tried booting into safe mode, wiping cache partition, clearing the data in the Google Framework app, moving the date on the S10 forward by a few days. The ATT supervisor finally gave up and suggested I contact Samsung for hardware support since the OTA wasn't going thru my phone.
I then chatted with Samsung tech support who kept telling me that they have not released Android 10 for the S10 yet. I gave them a link to the ATT website that clearly shows the release of Android 10 for the ATT S10 on Dec 17th, 2019 but the Samsung tech person kept saying they couldn't see that reference from the ATT website. After discussing this for 10 mins it was clear that this tech support person just wasn't getting it. Now, I'm questioning if this update is truly available for my ATT S10... Totally frustrated with this entire process.
