How do I perform a hot reboot on my device using the Terminal Emulator? I do not have busybox installed, but my phone is rooted. EDIT: I am looking for a solution to perform a hot reboot(see https://android.stackexchange.com/questions/174952/quick-question-hot-reboot-android) using the terminal emulator/shell.

I'm pretty sure my Samsung Galaxy A20 reboots daily, at around the same time, showing the usual signs of a reboot: sounds some kind of notification it's rebooted, takes a few seconds to find the SIM and reload the weather widget, asks for the password instead of a fingerprint to log in ("after a reboot"). However, Settings/About Phone/Status/Uptime says it's been up for weeks. What's going on with it? Is it just reloading part of the OS? Is this normal? Why is it rebooting daily?

Does it only trigger some kind of "shutdown -h now"? Or are there any hardware mechanisms involved? I want to know, what happens, if I shutdown the smartphone such as you can do with holding the "start" button for 10 to 20 seconds in most cases. More concrete: What happens, if I press the power button on my Huawei P20 for 10 seconds? What steps are taken exactly?

I can't even see the caller ID on the screen, when my phone soft reboots. It began when I did factory reset 2 days ago. No software installed besides system default apps. Phone: BLU Life One X (2016) rooted with Android Lollipop (5.1) This is what I get from logcat when there's incoming call.

I have Samsung Galaxy S2 GT-I9100, I had purchased new battery three days before and charged until it's full, after an hour I found my mobile switched off. I would like to know the how to rectify this issue.

I've got a pretty severe bug that results in my phone soft rebooting every time I try to make a phone call or a phone call would be coming in on the main number. What I did to try to fix (no luck): 1. Downloaded latest snapshot: https://download.cyanogenmod.org/get/jenkins/158646/cm-13.0-20160418-SNAPSHOT-ZNH0EAO2NL-shamu.zip 2. Downloaded latest gapps for 6.0: http://opengapps.org/ (ARM 6.0 Stock package) 3. Wiped /system, /data, dalvik cache & /cache 4. Installed #1 and #2 5. Wiped /internal storage 6. Updating radio/bootloader to latest available What's going on? This just started manifesting after I did a cm13Nighty (4-11-2016) > cm13Snapshot (4-18-2016) upgrade. I would've thought the reset would fix it at least? ---------- Other things I've tried with no luck: 1. Disabling/enabling WiFi Calling 2. Booting into Safe Mode 3. Deleting com.android.providers.x folders in /data/data & wiped Dalvik/cache again (This fixed WiFi calling consequently - *dysfunctional again after soft-crash* - *interesting...*)
