One UI 8.5 Update Bug/Software Issue

Send a error report though the support section of the members app, bottom right next to the community tab.

The issues described, including audio failure, unexpected reboots, and SIM manager errors, are consistent with bugs found in the One UI 8.5 beta for the Galaxy A55 5G. [1, 2]

Troubleshooting steps suggested in community forums for similar post-update issues include clearing the system cache and checking for further stabilization patches. [1]

If the device is on a beta build, reporting these issues directly to Samsung through the Members app is recommended to ensure they are addressed in the final stable release. [1, 2]

That sounds like an absolute nightmare of an update. What you are experiencing is a severe system-level breakdown, not a standard bug or app conflict. Because these issues persist in Safe Mode and involve completely different hardware systems (audio processing, cellular modems, and Bluetooth), it points to a catastrophic failure of the core Android services.

​What is Happening Under the Hood ​The Audio & Media Crashes: The Android processes responsible for handling sound (audioserver and mediaserver) are crashing and hanging. When the phone says the mic is "being used by another app," it means the system server itself has locked up the hardware and cannot release it. Playing a video forces the system to call these broken servers, resulting in a kernel panic and an instant reboot. ​The SIM Manager & Wi-Fi Drops: The phone's baseband modem — the chip responsible for all cellular and Wi-Fi communication — is failing to handshake with the OS. This is why the SIM manager is completely inaccessible and your eSIM is offline. ​The Battery Drain: Your processor is maxed out because it is caught in an endless background loop, constantly trying (and failing) to restart these crashed system services.

​This leaves two possible culprits: a deeply corrupted firmware installation where the One UI 8.5 partitions didn't write correctly, or a physical hardware failure on the motherboard (often the baseband or audio IC) triggered by the intense heat generated during the prolonged update process.

​To isolate whether this is software or hardware, step through these fixes. Order is critical here.

Sounds like a major software bug with the One UI 8.5 / Android 16 update. Since the issues started immediately after updating, it’s likely something in the system is failing — especially since audio, Bluetooth, SIM Manager, Wi‑Fi and even Safe Mode are affected.A few things you can try:
• Clear the cache partition
• Reset all settings (not data)
• Check for any new patches or hotfixes
• Run Samsung Members → Error reports so Samsung can log it
• If nothing improves, a full backup + factory reset might be the only stable fix until Samsung releases a patch

Since my wife updated to UI 8.5, her mobile signal has dropped it tries to connect to 4g after a minute reverts to E connection. After speaking to samsung support tried all troubleshooting and sent error report. Installed e-sim from another provider stills showing slow connection, will there be an update to 8.5

After updating my Samsung S23 to One UI 8.5, my Samsung Account keeps signing me out automatically and will not stay signed in.

I also do not have OneDrive installed on my device. No matter how many times I sign back into my Samsung Account, it eventually signs me out again.

I have already cleared the Samsung Account app cache and reinstalled the latest version of the Samsung Account app, but the issue still persists.

Could you please assist me with resolving this issue?
