The issue I am facing:
Is when I installed Termux on the android 7.1.2 Lineage OS running on Debian Buster 10 problem is when I install the setup screen is working typically after at some point after choosing the privacy mode (FTL) it does not show signs of installation complete use the DNS etc. (Chosen with admin web interface however it doesn't show on the assigned IP even with port: 24 removed)
For my system's local IP 192.168.0.134 on the DNS both primary and secondary it doesn't work instead my internet just stopped working.
There's no problem with the ram and Pi-hole terminal somehow is still functional.
(Uses WLAN0)
Details about my system:
The Hardware I'm running on is Samsung SM-T116NU however Lineage OS changed it to SM-T113NU instead with Armv7l architecture and was able to run Pi hole with only 1gb of ram the system uses 467mb including Termux itself and plenty for Pi-hole to eat.
What I have tried fixing:
I tried changing many options using the Curl installation DNS server, IP address, Default gateway, Terminal commands, and Reinstallations multiple times.
Suggestion
I'd suggest to make a Pi-Hole server app because many people got old Android phones/tablet those are unused and wasting money on a Raspberry Pi Zero W especially when sometimes some people doesn't want enable 2.4G which the cheapest Raspberry Pi device can offer with wifi. Android are however is built from Linux maybe use that advantage.
