When i put my phon to charge xperia sp my led start to flash first grean then change colors an then back to green ? when i disconect it from charger it stop to flash nead hellp ?
Check if you have any notifications, this is an issue of the rgb picker system in the bar i think, like the diode has to make a color from 3 colors; green, blue, red and it just fails at one color or displays for ex.. White onstead of green
To say shorter, if its software failure (wrong colors displayed to make one color) just factory reset.. If hardware, then warranty/fixing the diode will be the best shot
