I would like to keep this post to track all the software updates Galaxy S20+ is receiving in the Philippines:
7-Jun: As of right now I have received the June software update though I've been reading some contents over the internet that the Exynos variant has been receiving the June update already. Any insights?
20-Jun: I haven't received any updates. Yet I see in other countries they have already received 2 updates for their S20.
25-Jun: It's almost end of the month but I still haven't received the June update. What now, Samsung Philippines?
25-Aug: One UI 2.5 update is here and it comes with the August security patch. It is available for all Samsung Flagship phones starting on S9 series. For non flagship phones, stay put for the updates! Update is aroun 1096MB for S20+ with build number ending on BTH5
No updates yet for August. I'm still on July patch. In your case, I would suggest to clear data/cache of all the software update related apps in your phone. You can go to Settings > Apps (then on the three-dot menu above, Show System Apps) and search for 'update' and you can see all the software update related apps. If this doesn't work, you can reset your phone or go to the nearest service center for them to update your device.
