I have SE W810i. I find that when the phone is idle for a few seconds, display goes blank.
Can this be avoided i.e. I wish to see the display though I won’t be touching any keys. I couldn’t locate any suitable option in settings that would relate to this.

AFAIK there is no option for it, maybe a vkp patch is there. im not sure though.

i dont think there is a vkp patch there 4 this....but search.
