I plugged my phone in a car charger after that when i plug into normal charger it is not showing fast charging & also when i plug it into a fast charger it does not show charging or charge through a normal charger. Does anyone know how to fix this issue
Use original Samsung adaptors for car and home. If you want to use fast charging, make sure that fast charging option is turned on in Settings. If it's on then restart the phone and check. Also check 'Battery Status' and 'Cable charging' from diagnostics section in this samsung member app...
