Help background apps problem

[Rajesh1ization]

My phone has 2 gb ram and mediatek octa core CPU. My background apps automatically killed even when i have 800 mb free ram . It kills all background apps except last 4-5 apps. Last night , i was using apps(new to old)-MX player,crome,setting, uc browser , uc mini, opera mini, playstore, PayTM, mobikwik....
I was downloading in uc browser. After 30 minutes uc browser and uc mini killed automatically. This is a problem from last 1 month. What should i do ?

Have you messed with "background process limit" in Settings, Developer Options?

This is already in setting . I had just enabled it some months ago.

Any app killer or memory manager installed?

That's cool I was worried you had limited background processes
As Quickaudi says do you have any ram optimiser, Battery saver, task killer type apps installed?

Yes, i have trustgo installed from first day. But problem starts nearly one month ago. Mx player also has no control over brightness. Today i had opened crome ,opera mini ,uc,uc mini, whatsapp (in order) opera mini and uc browser killed but not crome and uc mini did not killed because it was in foreground.

Trustgo seems just to be a security app rather than a task killer/ram manager.

Sorry to say but I'd try a factory reset (back up everything important first)
