Apps getting minimised by itself on my Xperia Z1+ general querry related to Xperia Z!

[kaslokesh]

Since last few days when I'm using my phone, application are getting minimised by themself without me clicking home button. Be it Walkman app... whatsapp... or temple run or asphalt 8... anything... its occuring with every app...

By the way on many of the forum topics here it is suggested that use of antivirus or any RAM booster  or similar apps should be avoided... then PLEASE suggest me how to keep my mobile RAM free and way to empty cache memory as they are the main culprits behind phone hanging... i guess...

PLEASE also tell me what to do to avoid virus affecting my mobile...

In a nutshell... PLEASE give tips to keep my mobile performance at best at same time security also not affected..

It seems that you have answered your first question, you have those apps, that is most likely the cause of your issues, as for RAM, Android will free up RAM as it need it, you don't need to do anything 

as for antivirus, its debatable, antivirus apps slow down your phone, drain your battery and create other issues, so its up to the user to decide if its worth it or not. 

My suggestions, stay away from taskillers, task managers, antivirus, ram apps, booster apps; download apps from the playstore and double check the app permission, if a simple wallpaper require access to your contacts avoid it (that's an example)

Yes,uli gave you a great advice,viruses on android are not known,actually,their action is unknown,what they will do for your files.So keep away from 3rd party apps mentioned above and restart the phone regularly.

Problem still persists... I've no ram booster, battery saver, antivirus kind of app...

I'm having "my Xperia", "X-Alert for Xperia", "Enterprise services" activated as device administrators... android device manager is there but its not active. are these apps causing any problem??

I don't think those apps make you trouble.You could try disabling them,but I think it will not make any difference.

[kaslokesh]

this is strange... I'm not getting any apps which may cause minimizing of apps... 

I'd like to reiterate/ reclarify my problem...

actually problem is that apps get minimize and when opened again... opens at same place/point where it got minimized..

[kaslokesh]

Please also tell me how to remove LINE app... i dont use it... useless crap for me.

[_alexdon_]

Settings-apps-all-look for the app,see if you can remove it.

[kaslokesh]

no option to uninstall... i have uninstalled its updates and disabled it.

pls try to solve my main problem...  i.e., apps auto minimization......

It is a default app,that is why you can only disable it(you need to root to totally remove it).Are you sure you are not pressing home button?
