I modified my screen density to see if my tablet would act as a phone now all apps crashed. I need a stock build.prop do I can continue my use. I know noob mistake but it is mood night and want thinking that tablets aren't capable for phone's system wise. I realize that now and I hope someone can help me soon. I haven't been connected to Wi-Fi in weeks so my data is not backed up to Google and touchwiz does not work properly if I back it up do can someone help me please. I don't have time to browse the internet for hours searching for this. Thank you ahead of time.
