Am using LG L70 white, I can't switch sdcard to default and system is running of out space
To adjust the default save location of downloaded browser data, tap the applications icon from the home screen. Tap browser, then go to the menu key followed by settings. Select the advanced tab, followed by storage. Select either SD card or internal memory. I hope you will understand these steps. Optional but check Lg Optimus L70 Manual for detailed step by steps instructions.
