I have a Samsung Galaxy S4 I9505 Purple bought last September along with the extra battery kit. I've been changing the battery every day since September and came to notice today that the battery cover from the opening side has been torn about 1 cm.Does it mean the plastic use on the back cover by Samsung is poor quality or just low class plastic.
I've use note 2 before also with battery kit for a year and this didn't happen.
