Hey, i have been using my 6.1 plus for almost a week now and have encountered a series of issues. Firstly the some apps like Twitter amazon and some others are not working properly. I would refresh the twitter feed and it just wont refresh the feed, but am still getting notifications of new tweets, and when i click on notifications it shows cant refresh the tweet. Amazon app also same problem, the search just wont load up, it just shows a blank white screen. Its not wifi speed issue. Please tell me how to solve this issue.
