The system launcher on my phone has a data usage that is non-zero. I've already disabled background data for it.

I use Lawnchair2, but haven't tried to disable/uninstall the system launcher because I've read somewhere that it affects gesture navigation(Is it actually so?)

I know that apps like Netguard can help, but is there a more direct solution, other than rooting?

Are there any other adb commands that are useful, hopefully that are not too dangerous?

I've recently found
adb shell pm trim-caches 99999M
Clears all/most app cache, without having to install some cache clear or use Gfiles. I don't really use it often.

Along with this, does anyone know way to troubleshoot gmail not being able to download attachments on mobile data? I've not disabled background data for that.
Or should I make a separate post on it. Or would it be too tech-supporty?

I find it useful when I have to ask for files from another person without having to ask them to install the app.

Trebleshot has this option(screenshot attached) and I'm currently using it. But it's source seems to archived, so looking for an alternative if it exists.

Is android nearby share enough for this? Generally, I think that foss apps give me faster transfer speeds overy nearby share. Or is it just placebo?

I didn't see any paywall(uBlock?), but if it does spring up, then the link maybe useful

.7z seems to be good and I do recommend it to people, saying that it's better than regular zip. Have recently started using opus n webm files more.

I've also heard about jxl recently. Would be very nice to see it become popular, as it could reduce the size of my memes n screenshots folders. Faster webpage loading too.

Are there any other file formats that'll be useful to people, but isn't getting enough attention?

In the case of apps, Trebleshot seems to be good for android file sharing. I like it's web sharing option having an upload form. Helps me where I don't have to ask others to install an app to send me a file locally. Not sure about its encryption n security aspects, but I only have used it for local file sharing.

And what about other stuff similar to that, other than file formats or apps?

Recently have started exercising my neck. Not neck bridges and loaded things tho. Only safe n simple movements. Seems to be good, especially after using a monitor for some time. I think it's not much talked about, maybe because of the fear that people will overdo it?

I can download the same when I use wifi tho.

My phone is a Tecno Spark 8c, running Android 11.

Things I have tried:

1. Checked with different carriers. So it's probably not some block that my carrier has or my private dns settings being weird.
2. Cleared the data of the gmail app and ensured that it has access to media and background data.
3. Searched about the issue and saw people talking about clearing the data of downloads and the download manager. Have done that.
4. Reset the mobile data and app preferences in settings. No change after that too.

Related to this: I use Tachiyomi. Similar to attachments I never could download the extensions from within the app using mobile data(could get it manually from their site, so not an issue with their website). Recently the chapter downloads in the app have also stopped working on mobile data, displays No Network Connection available in the notification(have updated to Mihon).

I think it is some android bug. Or downloads or download manager or some other app having issues. I've disabled some bloatware on my phone and also have restricted background data to some apps.

Has anyone else dealt with a similar bug. Is there any fix for it(other than a full reset, if possible)?

Thanks in advance

The first one doesn't have a name.
Searching for the second one, TPMS, gave me results on Tyre Pressure Monitoring System. Didn't see any articles on android about it(Might be that I didn't search well enough too).

Is anyone familiar with these apps? What are they for?
Saw these apps on a Tecno Spark 8C, running Android 11.

Thanks in advance.

I have it installed on HDD, on a Lenovo Ideapad 3 gaming laptop, with a nvidia GTX 1650 Ti. I have windows installed, but it's on SSD, so it probably doesn't affect.

The battery life is not so good.

1. I have the proprietary nvidia drivers installed. In nvidia settings, I've set it to be in adaptive mode to save energy.
2. I've installed suse-prime and set it to offload. Setting it to intel doesn't get me to the graphical interface. Is there a way to fix that?
3. I use kde plasma and the effects and animations are turned off. I have disabled the cups.service, file indexing and other things I normally don't use.
4. Autocpufreq is installed and tlp is not.
5. I've also set noatime for root and home.
6. My screen brightness and sleep settings are kept low and I normally don't use more than 20% and at night only less than 5%.

I only get around an hour to 1.5 hrs of battery time on average. Are there ways to improve that?

Also my current boot time is around a minute to 1.5 minutes. Is it ok for hdd? Or are there things that I could easily try to speed it a bit more?

Thank you, for reading all this.
