My wife is using Tab S3. And finds it a bit slow to respond. I am looking at the Tab S8 Ultra. I know the CPU is more than twice as fast. But does this translate to response speed ?

Since my device was unproperly shut down because the battery stopped functioning (the battery is getting completely discharged at a level higher than 1%), it is rebooting in loops even in safe mode (more exactly it reboots about 3 to 5 seconds after finishing booting). So it means a file or permission wasn’t properly written in /data. But in my case, the /data partition is on the sd card thanks to Magisk root, so I have full access to it. Using a computer, I tried to put an additional Magisk startup script which is executed at boot in order to stream kernel log to a file, but the result isn’t useful as the last line of the log file looks something like this : [ 72.480828] Ke **So which is the command to execute or file to write in /proc or /sys in order to disable automatic reboot after a kernel panic** so the kernel finish to flush the log file ?

Simple question but I couldn t find the answer anywhere. It is not part of ip informations and the information is not trivial when being connected to the Internet over lte. getprop | grep dns is returning nothing.

I just purchased a used Samsung Tab S3 which comes with Verizon network capabilities. I don't want to use cell capabilities, just Wifi. After setup, on the lock screen and in the notification center is a message from "Setup Wizard" that says "Activation Incomplete" and to call Verizon support to activate the device (which I don't want to do). Is there a way to remove this message without calling Verizon?

I would like to convert my android phone into a personal pcbx (being able to perform basic automated answering based on speech and who is calling and performs hang up). Something requiring the power of [Asterisk](https://en.wikipedia.org/wiki/Asterisk_(PBX)) (unless you know an alternative designed for android of course). There are a lot of tutorials on how to this through sip on rooted devices, but in my case, I want to do it using **the phone number of my sim card** which of course is tied to a provider that doesn’t give such option ([they gave sip credentials during years but this is something now terminated](https://www.change.org/p/xavier-niel-r%C3%A9tablissement-du-service-sip-chez-free)) in order to reach the public switched network without any additional fees. This wouldn’t be a problem on Linux as virtually every Linux compatible phone modules have a bridge for [Asterisk](https://en.wikipedia.org/wiki/Asterisk_(PBX)) . But for Android devices, I read (I fail to remember where) that not only the modules designed for android phones aren’t provided with an Asterisk bridge, but that almost all the drivers controlling them are so closed source that it’s impossible to compile a custom kernel using them (that building is still possible but without support for the modem) and that while everything related to telephony **is controlled by a daemon** (I don’t remember it’s name), it has to be patched by oem because the kernel interface exposed to userland is closed source too and undocumented. So that no apps allow controlling the hardware phone besides calling numbers and that even being root doesn’t change it. If not, how can I perform such advanced usage?

I chose to boot android on the from the sdcard in order to have more storage. So I dumped though dd the internal 32Gb storage to the 256Gb sdcard with the partition table included. By just changing the kernel command line and the ro.boot.bootdevice property, the device now boots from the sd card after loading the kernel from the internal storage. * I then put the sd card in a pc, fixed the partition table size to match the one of the sd and then set up the userdata partition (/data) to fill the remaining space. * Then I wiped the filesystem and performed a factory reset in order to hope it would create a 250Gb filesystem for /data. But [while data was mounted from the sd card and that the mapped block device was 250Gb large](https://superuser.com/a/1537505/282033) , it was formated using 25Gb instead of 250GB (the original size on internal storage). This means I have to grow the /data filesystem using an external computer. Now the question is, what’s the exact dmsetup command in order to create the block device for decrypting it for growing the ext4 filesystem using resize2fs? Given also I forgot which is the file containing the decryption key.

In my case, I don’t want to permanently root my own device and if possible, I want to modify the /data partition directly. In order to do so, I want to add a single file to the /system partition or even apply capabilities on a single executable. That means no apk ; no new apps ; no bootloader changes. But everything I found for creating my own ota for rooting explains how to use adb to apply it, not how to build such a file myself. Or suppose that I’m building for a firmware I designed myself for which I have the signing keys (whereas the aim is to do it for stock Samsung). So **how to create my own file‑based** (with the aim to modify file permissions to existing files) **ota zip file which can be installed through adb sideload on all devices as SuperSu does** ?

In my case, I would really be annoyed to no longer have phone/lte working because of the detection of a non Samsung firmware. So I’d like to root the device (or boot from the sd card) by modifying the current firmware (especially since an official Samsung update changed the bootloader along with the kernel last month). I want to dump full storage including the apps stored on /data. But so far, all I found doesn’t work on the latest Samsung or is for Windows only.

A well‑known workaround in such case is this *(and as you can see with those command this didn’t worked for me)* : C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell gts3llte:/ $ sm set-force-adoptable on gts3llte:/ $ sm list-disks adoptable disk:179,64 gts3llte:/ $ sm partition disk:179,64 mixed 50 gts3llte:/ $ sm mount private:179,67 gts3llte:/ $ sm list-volumes all private:179,67 unmountable private mounted null public:179,65 mounted 3531-1DC7 emulated mounted null gts3llte:/ $ reboot C:\Program Files (x86)\Minimal ADB and Fastboot> But starting with Android Pie, those commands [were moved from vold to Binder and as sm only affects vold some of the commands above are now dummy.](https://android.googlesource.com/platform/system/vold/+/11c2d380a786d9e304416be98881b90b74ff666d) . This also affects the way to do it with root. Though in my case, now that I did this, going to storage settings systematically crash the settings app. So how to use sd card as internal storage with newer versions of android ?

Everything is in the title It’s not about the bands currently in use but those my device can supports (my cell phone provider is refusing to let me access full of their supportted bands)… As I don t know the target region of my device, the only way to know is to find which ones are supported in practice.

I’m in a situation where even with forbidding motorway I’m ending up with a 110 Km deviation to the north or the south for driving straight to the east. I want the shortest path in Km even if takes way longer and burn more fuel (fuel economic routes also have such high deviation). The best way to achieve this is to configure for pedestrian mode *(I checked in that case the route is almost a straight line instead of a curve with car mode whatever the guiding software)*. The problem is I’m not find taking stairs with the car. So how to get the shortest path which excludes roads where cars can’t go through ?
