YSK: you can setup pihole on any old rooted android (5.0+) device
I just discovered this and it works fantastically on any old / unused android device you might have lying around, I was shocked at how easy it was, all the instructions are there, once you have it running all you need to do is set your router DNS settings to your pihole IP address and presto! Ads and trackers are gone!
Most mobile devices won't work without batteries. The best way to work around this is to supply it with 4.2V (anything between 3V and 4.2V will do) over the battery connector.
This could be a long shot but if it's a Samsung Galaxy Tab S, the battery connector solder joints kinda die after a while, which can either be fixed by reflowing them or by applying pressure (I have a tablet with that issue). You could try pressing on the battery connector and see if it works then.
I looked a little closer at the battery connectors and when pulling the battery out I must have yanked the little wires out of the clip just ever so slightly (I could see a little bit of them reflecting on one side) I carefully pushed them back in and avast! There is life again! Thank you kind stranger!
Yeah I briefly tried installing advanced charge controller, its a magisk module that let's you stop the charge at a certain point but it didn't take for some reason, that's when I decided to remove the battery which I fear was a mistake as now it's dead as a dodo, that said I do also have a redmi note 8 that is possibly better equipped for the task (much stronger CPU and up to date OS)
Is there any modern day android phones that work without the battery. I feel like they'd probably run POST checks to make sure there's a battery inside. Maybe fairphoness?
The FP3 requires a battery at least. Ironically the device will actually still turn on and be usable if you removed ALL the modules besides the display module 😅 and of course the mandatory battery
