Lots of regular apps dont work properly. Like Twitter app , doen't load profile pics and media links , whatsapp GIF stickers don't load, Google drive doesn't load . All these app's i use on a daily basis and doesn't load on the first time . I have to relaunch these apps several times , force stop, clear cache to get them to work properly . Then when i close these apps , they are back to non-loading state and i have to close, force stop, clear cache again. 

This is absolutely annoying for such a costly premium phone. Just to clarify my network strength is super strong in my laptop,desktops and other phones . And speed is 75 MPBPS. 

The other issues i have are , mobile newtwork strength always is 1 or 2 bars , where as my other phones have full strength with same network at same location . Battery also dont last entire day , without gaming or without any photo or video taking , its absolutely pathetic.
