I want to keep my lockscreen on longer than the few seconds it does now by default. I don't see any settings to change this in the menus. Is there a way to keep it on for 10 minutes or even permanently?
OS: 4.1 Phone: S3
i guess what you are trying to say is that you want the screen to stay for a longer period of time after getting locked.
If that's the query then it has a very simple answer.
Simply go to settings>display. Now there you must see something like 'Screen timeout'. Just tap on that and choose the time you want to keep the screen awake.
Now it'll also keep the home screen awake for the selected time. This is because there are no settings for changing the screen timeouts differently for home and lock screens.
What you can do now is simply press the lock screen button at the top right. Once the screen gets locked press it again such that the lock screen appears. Now it'll say for the time you selected. :)
Hope it helped. A positive vote is always appreciated. :D
just maybe I've got the answer to your second problem too!
OK so here it is, head over to Google play store (link here- https://play.google.com/store/apps/details?id=com.chemdroid.screentimeouttoggle&hl=en&referrer=utm_source%3Dgoogle%26utm_medium%3Dorganic%26utm_term%3Dscreen+timeout+toggle ) and download this app called Screen Timeout Toggle.
Now open the app and tick 'Always Active'. Now the screen will never time out. Now what you must do is lock the device's screen manually by pressing the lock button. Now if you slide down it must say 'screen must stay on'. If it doesn't show that then you must tap on the toggle option. This would make it start. Now lock the screen again and there you have it. It'll never time out.
There's just only one problem, and that is that the developer says that 'Now it works for 4.2 also' . So I'm just not sure that whether it'd work for you as you said that your device is running 4.1 . If it worked then please let me know. Positive vie is always encouraged :D
