In FUTO keyboard you can customize whole layouts so you can add tab-space as well

Ok, I did test it.

1. I set up DNS server on my PC using Technitium.
2. I add zone a.local and add record with device A's IP.
3. I add zone b.local and add record with device B's IP.
4. On device A (Android 11) I go to Setting » WiFi and set DNS to PC's IP.
5. On device B (Android 13) I go to Settings » WiFi and:
   • Change IP to static
   • Change both DNS1 and DNS2 to PC's IP.
6. I ran some file served over http on both devices.
7. I visit http://a.local/ on device B ❯ A's Files accessed
8. I visit http://b.local/ on device A ❯ B's Files accessed

Everything works.

Note:

• it took DNS server about 1min to add the records (idk why).
• It seems devices caches NAME_NOT_RELOVED so if it failed it will be cached as such for at least a few minutes.

I believe that using ipleak.net [...] will not show you the internal DNS server you are using within your local network.

You're right. It won't show internal one. As I mentioned I don't have internal DNS server set up, so I only used it to check whether changing DNS in wifi settings will actually take effect, and it did. That's why I believe setting it to internal one should take effect as well.

I may try to setup custom DNS in my local network when I have some free time.

I visited http://ipleak.net/ to check which dns is used.
In Termux nslookup will use 8.8.8.8, but I suspect it takes it from Termux environment that doesn't sync with android settings.

I don't have a custom DNS server configured, but that's what I tested:

• Went to Settings » Connections and Share » Private DNS - made sure it is off (it takes priority when set)
• Went to Settings » WiFi » [My local network] » DNS1 and entered my router's IP

After that it started to use my ISP's DNS servers (preconfigured in router) instead of CloudFlare 1.1.1.1 (what was default on my android when connecting to WiFi

Not sure about e/OS but generally on android you can set DNS when connecting to Wifi.
So you should be able to change that in Settings » WIFI » [Your local network] » DNS

Is there a way to filter out system apps?

But you need to create account first :|

It's for modifying applications to remove or add some features. Like removing adds and suggested content or giving users access to internal storage of apps. All patches should be listed on their website if you are curious what it can do.

WTF. In the past I updated my tablet and after that it started to discharge within two days (not a week as it used to). The only way to fix it was to clear cache partition. And now they are removing that option.

I never had a need for such app, but I guess if you search for "CCTV" in the store you will find a few. That one looks promising for example.

Just keep in mind that videos quickly grow in volume, so you need a fair amount of free space to keep recording for the whole night.

I doubt it shows noise in dB, but you can try to start some app for measuring dB and record the screen instead (?)

Stealth Audio Player can do exactly that. There is "Activate for ALL APPS" option.
