I'm having problems installing apps?After a software update, I keep getting an error message when I try to install new apps.
回答“Crack on the screen”A small crack is typically okay to leave as-is as long as the display is working and the touch screen is responding. Even if the crack does grow, as long as it is just the glass and nothing underneath is damaged, it is okay to continue regular use.
回答“My device is working too slow”Try restarting your device. If that doesn't work, try deleting unwanted/unneeded apps and files/photos. Your device memory might be full.
