experienced the same problem one month ago.I tried many methods including resetting the phone which didnot work at all.But,for me the below described method worked out.

Solution or fix:
Revert back your android OS to older version or burn your android OS rom once again.You no need to root your phone.You can download and install an official rom version.If you are installing an older version,after install you can upgrade to the latest OS version any time.For example,if you have a samsung android smart phone,after installing an older OS version,you can make use of the Samsung Kies to upgrade to the latest version available.For installing the custom rom you can use Odin multi downloader.
