It’s called “Caffeinate” (I’m avoiding posting the direct link just so I don’t break any self promotion rules), I made it in the Android 7 days when the quick settings Tile API came out to replicate the similar tile that was available in CyanogenMod. It ended up getting way more downloads than I ever expected honestly - I just wanted to try the new API haha.
I know that Caffeinate itself doesn’t use up a lot of RAM (the only thing it does when its active is create a persistent notification and creates a wakelock in order to keep the screen active), but perhaps the lower end Samsung device models just have less RAM available, so opening a browser or such kills it.
I tried your caffeinate app. The last time I checked, it was using 32mb while running. Currently, using 11mb. Android says it uses an average of 143kb with a maximum of 7.8mb for the whole day.
It has been installed for the past 3 days, and I try it once a day from the drop-down tile. It hasn’t been killed or reloaded yet.
I have 6GB of ram with 6GB of ram plus enabled. I guess its low ram and cpu usage make it never likely to be booted off ram. Those users who complain must be using Samsung devices on older oneui and / or low ram like 3GB or 4GB.
Well I definitely am glad to hear that! Yeah the situation is just unfortunate, as there’s really nothing I can do for the users who are getting the issue - since as you’ve seen, Caffeinate is already really light on RAM usage (which would normally be one of the only ways to try to remedy the issue as a developer, from what I can tell).
In the end I just decided to keep it compatible for all mobile devices, though I did consider adding a “compatibility warning” type of banner to the app or a one-time notification for devices that had a small amount of RAM. Eventually the emails stopped coming in about it though so I figured either the problem ended up resolving itself as updates to the platform occurred, or everyone who was going to run into the issue already ran into the issue. I’ve pretty much considered the app to be feature complete now, short of any Android changes that break it (such as when notification channels was introduced, followed by full-on notification runtime permission requirements).
You said the app is feature complete. But, if you find the time and energy to spend. You can probably try to add a dark theme that utilizes the “follow system” theme setting. And later if desired material you theming support. Otherwise, it does the job and is good as far as it can go.
