HyperOS update broke mobile data on Redmi Note 15 Pro+ & unusable settings app
Recent update on my Redmi Note 15 Pro+ to HyperOS (3.0.1), completely broke my mobile data connection. While Wi-Fi works, cellular data fails entirely. To make matters worse, attempting to access Settings > SIM cards > APN causes the UI to crash/flicker and jump back continuously. Standard system functions like downloading the latest OS package from "About Phone" or launching settings activities are unresponsive or crash. The SIM card works perfectly in other non-Xiaomi devices, confirming this is strictly a corrupted OS update issue from Xiaomi. On top of this, trying to navigate system recovery or Mi Account recovery is unnecessarily painful and convoluted. Selling phones with buggy updates that break basic connectivity—and offering no simple in-system recovery mechanism—is unacceptable for a flagship-tier device. Would not recommend until Xiaomi fixes their software stability.
