In my phone (Moto E2 running on 5.0.2) while I'm using facebook, I found a frequent reloading issue.
The problem happens only when I go to an external link to read some articles and after switching back to the app it shows only a white background and it load from the top, previously it used to show from where I left off, first I thought it may be bug in facebook app, then I noticed all my apps are having such a crazy reloading problem, another example is google plus, but luckily after reloading it show from where I left off..!
It can be a virus issue or a setting issue, so before I reset my phone I would like to know if there is a tweak or solution for this...
