Common Samsung Galaxy issues
No signal / SIM not detected
Reseat the SIM, toggle Airplane Mode, and check the preferred network mode in Settings → Connections → Mobile networks (e.g. 5G/LTE).
An app keeps crashing
Clear that app’s cache in Settings → Apps → [app] → Storage. Still crashing? Restart in Safe Mode (hold Power, then press & hold “Power off”) to check if another app is the cause.
Won’t charge
Use the official cable/adapter, gently clean the USB-C port, and try another socket. Fast charging needs a compatible charger.
Running slowly
Free up storage, close background apps, and check Battery and device care → Optimise now.
