There is a lot of problem of charging error in Samsung mobiles. If your Samsung M02 or A02 mobile is not charging or is repeatedly showing charging error, then this guide is for you. This is a very permanent solution. The problem is mostly seen with the charging board. There is no need to change the charging board, it can be repaired in this board itself.


Cause of charging error
If some resistors near the charging port in Samsung Galaxy M02 / A02 get damaged or the voltage starts dropping, charging problems occur, especially the 1.8v line gets affected.
Solution
- Check the 400k resistors (1.8v line):-
This resistor measurement is important
If there is voltage drop or the resistor value is wrong, then it needs to be replaced
If there is voltage drop or the resistor value is wrong, then it needs to be replaced
- Replace the 100k resistors:–
This resistor often gets damaged causing the charging line to stop working.
Replace it with a new 100k resistor

Fine result
After applying this solution, charging becomes completely fine in both Samsung M02 and Samsung A02 and the mobile starts charging normally.
