I have a lot of outside applications installed in my previous os. And I have downloaded most of them from the internet. Some apps are very hard to install. I have a limited one-day data pack to 2 GB so again installing those apps will take around the time of a whole month or more than that. Installing all that apps again will be a very big pain for me.
Is there any way to backup apps?
(I think you can understand my problem.)
