Browser keeps refreshing tabs I have a LG V480 (1GB RAM; LG Lollipop 5.0.2), when switching from one tab to another tab which was loaded before, it will reload it. 

Example: 3 tabs with 3 websites, everytime i switch tab it will reload the tab i switch to.

Its very annoying, if i had written this question on the tablet and for some reason i clicked in another tab, when returning to the question, i had to write all over again! Its not multitasked, its time/bandwidth wasting. Also tried to set to default the tablet, but the issue remains.

Tried with Chrome (preferred one), Firefox, Opera, some others browsers, and all behaves like this, some better, other worse.

How can i solve this issue?
Definitely those tabs are just getting killed. Remember that in Chrome, page renderers run in separate processes for security. Once a renderer process has been put into background, the system is free to kill it. According to https://code.google.com/p/android/issues/detail?id=98332, the issue with over-aggressive process killing should be resolved in the 5.1 update. Hopefully, LG will release this update for V480 soon.
