The menu you get when you press the shutdown key should give you a list of options including Shutdown, Restart etc. If it doesn't, your phone's manufacturer might have left it out of the ROM.

Use the app Quick Boot to restart your device (a rooted device). Answer seems to be given partially here: I've rooted my phone. Now what? What do I gain from rooting? Use the app Quick Boot to restart your device. Start the Quick boot app and choose 'Reboot' and there you go.

I'm not sure about logging but, safe mode disables many system services during boot. On some systems it can bypass the security pattern or pin. I haven't found any additional features. It seems to be more for reducing features for the sake of diagnostics. Windows has a similar feature. I've posted a link on starting safe mode on a variety of devices for ...

I had a similar random-rebooting problem, and after one such reboot, I hooked up the phone to my laptop and ran "adb bugreport" on it. I got what looked like useful information, and attached it to the bug. So I think at least some log information survives a reboot. Here's the bug, btw: http://code.google.com/p/android/issues/detail?id=24118

Regarding your first 2 questions (reboot / suspend) : No this is not normal, however, as a lot of software from a lot of different vendors are running on your phone, it's inevitable that under certain conditions certain apps can cause your phone to "crash". In an ideal world, no piece of software should be able to crash the underlying OS and the phone, ...

If it works like other "hot boot" apps and functions, then it basically restarts the Android GUI processes/threads. There was an XDA news post a while back after someone made an app for it where the app author described it as such: Hot reboot by rebooting only the graphical Android shell. From what I know it's sort of equivalent to restarting your X ...

Engadget has just reported that the Nexus S is having issues with random reboots (http://www.engadget.com/2011/02/15/nexus-s-suffering-from-random-data-loss-reboots/) and apparently fixes are coming. To see the log you can get the following app: aLogCat

Simple, really: Android is safely shutting down vital parts of the run-time, broadcasting intents to notify apps/services to gracefully shut down, which in turn flush their caches for data and shared-preferences, save what-nots to the sqlite database, etc. In other words, apps and services are given a chance to do their clean up systematically. The ...

Force stop is a one-off action, not a thing you enable or disable. Force-stopping an app doesn't prevent it restarting any time it would normally start: when you launch it from the apps menu, or through a share action, or automatically via an alarm, broadcast, or on start-up. The question you link to talks about whether the button is clickable (enabled) or ...

As pointed out by my other answer, and confirmed by the OP for the given device with reference to a blog article on the Z1, most devices with non-removable batteries have other means to "disconnect from power", usually "reset buttons" or "reset holes" to be poked with a pen or similar object. This should remedy in situations where the device freezes in a way ...

The volume up + power option also works for the Samsung Galaxy S. You have to hold for about 10 seconds before restart, but it works.

Press (volume up + Power) at the same time. It will reboot the phone. Tested on Galaxy S Captivate.

I finally found out why! :D When the phone boots - at least if I use go launcher - if the sd card is not completely mounted apps "get lost". I've completely solved the problem activating my phone card pin code. I turn on the phone, wait on the pin code screen without entering it for a minute and then I enter the pin: everything is perfect. I think the ...

If it was working before, try uninstalling the app(s) you put on it most recently. They might be the problem. After that, the first thing to try is probably a factory reset. Edit: OK, so basically your ROM is totally screwed up. I would just replace it. Some official firmware is linked in this XDA post. Download whichever you prefer, then use Odin as ...

Pressing and holding the phone's power button for a few seconds might do the trick. It switches off my Android phones.

Have you moved them to or from the SD card? My app icons disappear from my home screen when they are moved.

Logs are written even when logcat is not connected, although I believe the logs are limited to a certain maximum size. They are, however, cleared on reboot. You can try using an app such as aLogCat to persist the logs to files, and hope it can catch whatever is misbehaving "in the act".


3

Do a factory reset (here are instructions). Grab the update from here (dead link) and re-flash it. You may need to put it in the /sdcard folder and name it update.zip, or use Fastboot through adb (you need to install the Android SDK on your PC).

I read similar reports lately, related to Titanium Backup.. When it runs, it kills apps to back them up, causing the phone process to restart. If you aren't running something similar, I would recommend using USB debugging and the SDK to capture log data.. Known as "logcat" in the Android world. Oh -- Here's an easy way to capture and review log data on ...

There's an app for, well, turning off the sound on shutdown and then back on at startup. As I've got Tasker I no longer use it, but you're looking for Silent Boot by Anton Weber.

I have uninstalled TaskKiller as I read that these types of applications can cause stability issues on Android 2.1 and 2.2. So far so good...

Android is pretty resistant to faults resulting from sudden power loss, but there's always a risk of data corruption/loss, depending on open apps and files at the moment. Have you tried holding the power button longer, for about 15 seconds (until the screen goes black and the normal startup screen appears)? On my Galaxy S this triggers a hard reboot, ...

The first thing I would try to do is to retrieve the logs of the errors via ADB, and/or crash dumps. Retrieving the logs is tricky, since the log cache gets erased on reboot. If the phone reboots even while sitting on a charger, try running adb logcat continuously (you will need Android SDK and USB drivers installed and configured on your PC.) When the ...

I would unlock the bootloader, and flash a new image... You can find all the information you need on this page: http://forum.xda-developers.com/showthread.php?t=1392310 Hope you found my answer helpful :)

You shouldn't need to restart after freezing an app. Once you freeze the app, it should disappear from the apps drawer.

You can't change this. Simple solution: Don't shut down your phone any more (except when it runs out of battery). If you switch off your screen only, your phone will go to sleep and won't consume much power. If it still eats too much battery, consider disabling wifi, background data, sync or even switching to airplane mode. As noted in the comments the logo ...

The reason it does not work properly is this: The init.rc script resides in within the RAMDisk attached to the boot image. Hence the init.rc script that was edited and pushed across is now overwritten by the boot image's own script upon reboot - effectively changes are lost! You need to extract the boot image, using every boot image has the kernel and ...

If you can connect using adb (usb debugging), you can simply use the command "reboot". If you're rooted and have a terminal emulator installed, "su reboot" will do the same thing. The reboot command will also accept arguments of "recovery" or "bootloader", which will reboot you into the recovery or bootloader respectively.

You could start by not overclocking the device. That's a common cause of system instability even in ROMs that are usually stable. If it's still unstable because of that, it could just be instability caused by (bugs in) the ROM you're using. Try flashing back to the the stock HTC ROM. If it's still unstable after flashing back to the stock ROM, it could be ...

If the device freezes, usually you can long press the power button. Depending on the configuration of the device, it will either turn the device off completely (e.g. Nexus 7, HTC Butterfly S) or make the device do a restart.
