@computersalat You miss the point, there was a port for it, but it was not complete, i.e. no sound and the porter couldn't resolve it for their reasons. I have a few devices that have UT ported to them but the port has failed, usually no sound (a bit of a necessity with a communications device), no modem, wifi and so on. Porting devices fail for many reasons, one of the main reasons is proprietary drivers (that require reverse engineering) and kernel issues which can take a lot of dedication to sort out...

@Moem Yes, I thought so too, and it matches the description in the wiki. https://wiki.ubuntuusers.de/Ubuntu_Touch/UT_Tweak_Tool/ In my tests, however, the opposite was true. There might be another reason for this. I’ll repeat the test with different scenarios and log the power consumption in sleep mode. -10 hours of standby (all apps with background suspension) -10 hours of standby (all apps without background suspension) In any case, battery consumption in standby mode (accessible only via phone calls and text messages + alarm clock function) can be reduced to a minimum. It feels like a Nokia 3210 with up to 260 hours of battery life, with the difference that modern smartphone features are available at all times.

@gpatel-fr the second one looks like it successfully wrote something to su and tried to run it, but the su contents was misunderstood by OS The mitigation should be the same as for desktop Linux: disabling affected modules completely in modprobe config: install esp4 /bin/false install esp6 /bin/false install rxrpc /bin/false install algif_aead /bin/false

take this guys really cool app https://forums.ubports.com/topic/12261/for-testing-radio-alarm-for-ubuntu-touch .....dude had to make a unconfined app for a alarm clock .....let that sink in for a minute with the security implication of app confinement .....the security is great but i think the execution needs for work ....also am i not understanding?? ....like i know content hub needs more completion ...so is this a task for content hub that just never came to be so im disgruntled not knowing thats where the doorway to capability lives?? or supposed to live?? but was never implemented??? maybe i need to learn more about the original history of design direction for UT

Updated the original post with new links, as I have added a tutorial, per Vladimir's great suggestion. [image: 1779060430118-tutorial.png]
