Hey, I’m using a Nothing Phone (3A) (Indian variant) running Nothing OS 3.2 on Android 15.
Before the latest September patch, I occasionally had random notification delays on WhatsApp, Messenger,etc. I’ve already disabled all battery optimizations, sleep modes, and background restrictions. Haven’t used ADB shell mode tweaks yet.
After the update, the issue actually got worse — notifications now arrive with about a 3-minute delay. It’s still random, but this 3-minute pattern keeps showing up again and again. It happened to me thrice within a day. I’m truly at loss here about what’s causing it.
