Why is my phone freezing, rebooting, draining my battery, and/or slow?
One common root cause of concerns such as freezing, random restarts, battery drain, sluggish or random actions, unexpected errors, or other unexpected behaviors are 3 rd party apps.
Safe mode prevents 3 rd party apps from initializing, allowing devices to be tested without 3 rd party interference.
Step 1 – Unmount the Memory Card
Similar to 3 rd party apps, corrupt, damaged, or performance-impacting memory cards can cause freezing, random actions, etc. The first step in the Safe Mode Experience is to unmount the memory card and retest the device.
Remember: Samsung strongly recommends the customer use a class 10 or newer memory card for best results.
Step 2 – Retest in Safe Mode
Once the memory card has been eliminated as the root cause, using safe mode will help eliminate a 3 rd party app as the root cause. If the concern doesn’t persist in safe mode, the root cause is a 3 rd party app.
Tip: Safe mode doesn’t pinpoint which 3 rd party app is responsible. Test by removing any recently added or updated applications and retest.
Step 3– Reset All Settings
Once the memory card and 3 rd party apps have been eliminated as the root cause, reset all settings will be beneficial for testing prior to a factory data reset.
Tip: Resetting all settings and/or resetting network settings may delete saved Wi-Fi connections, Bluetooth pairings, etc.
