  • Same, but also for TrackPoint. I have the touchpad disabled. I don’t need to move my hand away from keyboard, I can endlessly scroll through pages at varying speeds just by finger pressure, and even cooler, I can scroll sideways just as easily. Oh, and I can also scroll both vertically and horizontally combined, to just easily navigate in the 2D space, pretty cool.
    Although I also use the touchscreen a lot. I don’t want a regular laptop anymore. Unfortunately the 360 ThinkPads seem a bit rare when trying to find a used one.

    Let me check what I could get if I tried to buy it new.
    ThinkPad L13. Intel Core Ultra 5 125U, 16GB LPDDR5, 512GB SSD, 1920x1200 IPS, WiFi 6E, plastic body. €1,398.76 with 3% student discount. That seems overpriced, at the very least for my use case.






  • I achieve the same by disabling VoLTE and VoWiFi and setting the phone to LTE only in *#*#4636#*#*.

    I love these service menus. *#*#3646633#*#* has so much stuff to permanently screw up on some MediaTeks. But also some useful ones like selection of frequency bands, or even specific frequency and cell id.
    But yeah, some settings can persist factory reset, and some may even be illegal like Tx tests (verified that it does transmit garbage on selected frequency with SDR) or IMEI change. Not all settings are on all devices, and they may even be partially broken.

    But yeah, these settings are don’t touch it for the most part (some are just huge lists of undocumented variables). Some don’t even seem to be resettable from the menu, I mean menus where you select one option, but by default they are unset. And the band mode selection on Moto G54 5G was… interesting. Rather than a nice selection menu, you can type in a number and select to add or remove it from a vector variable for 4G and 5G. Of course, nowhere does it list valid options or give a reset button.

    And lastly a thing that serves me as a warning for future, when I was playing around with a leaked service program for some Realtek Ethernet adapter, I found out what eFuse memory is. There is no going back.











  • For quick graphical management I use FX File Explorer because it keeps the timestamps when moving files.

    For something more I use… Termux. I like to sort things based on timestamps as well, but often I like to set some custom modification time, or copy modification time of a file being replaced (e.g. replacing old 128kbps MP3 for FLAC), and I don’t know of any other way than touch.
    Similarly I don’t know what else to use for syncing directories other than rsync.
    Plus, I can run SSH in Termux, that means Rsync-ing between PC and my phone is pretty easy.
    And it also means I can mount the phone over SSHFS (granted KDE Connect already takes care of this).
    I can also use GPG for encryption and decryption of files.
    And Vim works fine for me for text editing too.
    And now since I already have that, say I want to access some files on any computer. It probably has a browser, and Termux has NGINX, coupled with FancyIndex it gets pretty nice for file access. I like the Material theme.

    Now, a bit of a disclaimer: BE CAREFUL WHAT ADDRESSES THE PHONE IS LISTENING ON
    I set them manually rather than the typical default of all interfaces. Unfortunately, Android seems to have no firewall. I can easily reach things on my phone connected to mobile data thanks to IPv6. This may or may not be desired. Oh, and NAT isn’t for security either, so don’t think you’re safe because you only use IPv4. Perhaps devices behind same NAT aren’t isolated.

    Edit: Example of the WebUI with Material theme (sorted by date because I was able to set the file timestamps):
