I am developing an app and when I uninstall the phone kind of semi-reboots.
This is my old post:
I have a strange problem with my phone. I am using SAMSUNG GALAXY 5
(GT-I5500) with Android 2.2 on it (not rooted).
I am an android developer and I have been doing pretty advanced apps.
However, sometimes when I am testing and installing an application the
phone reboots.
I'm starting it trough Eclipse but I do not know what exactly what
causes the phone to reboot.
It is not heat for sure, as I keep my phone cool enough.
It is not from the app source itself as the phone doesn't reboot while I am using the application but on installing time
It is not storage I think, because I have 26 MB internal and 1GB external memory free and the app is no more than 2 MB.
So my question is what could cause the phone to reboot?
In this context I define "reboot" as the phone showing the initial SAMSUNG screen, like normal booting but without the prompt for PIN. This is why I conclude it is something like semi-reboot or I do not exactly know.
Having experienced the same problem, I found that deleting dalvik cache and formatting cache partition helped - I can't tell which one of those two did the trick, but I can now happily uninstall apps again, without the device spontaneously rebooting.
Both operations I was able to perform in recovery mode, using ClockWorkMod rescue system, and they are non-destructive. No actual data or apps are lost, only next reboot takes longer, due to dalvik cache being rebuilt.
Today, close to a month later, that problem showed again, so I was able to test which of those two action fixes it. Turns out it was erasing the cache. Dalvik cache was left alone, deletion was possible afterwars nevertheless.
I have this exact problem with my LG G4. Whenever I try to uninstall an app the phone will just reboot. Luckily there is a way to remove unwanted apps if your phone has an expandable memory option through micro SD. Just transfer the unwanted app on the SD card then remove the card. The app will no longer exist on your phone. You can then just delete the app from your SD card using a PC. This doesn't help resolve the actual OS issue on your device but at least it's a quick fix for anyone who's looking to free up some space. Hope it helps!
Spontaneous reboots under unclear conditions, one of the "fun" things you get for free with Android. Not on each and every device, OS version or combination thereof, but quite too often.
With the following instructions you will loose all your data on your phone.
Try this: Get into the recovery mode (adb reboot recovery or start the phone with pressing (and holding) volume down, then press and hold the center key, then power on), then wipe data/factory reset, wipe cache partition.
(I experienced similar reboots but not with an I5500, so I don't know if this will help in this situation. It helped with a Motorola Milestone/Droid after upgrading to Android 2.2.)
I was able to fix this problem by wiping the davilk-cache thanks to Deleted User's experience. However, wiping the cache partition was not necessary in my case. I'm rooted stock Android 4.4.2 KitKat on a Galaxy Tab 3 SM-T210R.

I've been trying to do this for 3 days now but i can't seem to get this to work.
So the gist of it is, I have an LG G6 running Android 8.0, with a 128Gb micro-SD card, I'm running out of internal space, and apparently LG and Samsung remove the adoptable storage feature from their android versions, I found a turn around to this which was to use ADB to partition the SD drive myself, and getting it to behave as internal memory, at first I had an issue with ADB even noticing my device, which I fixed by enabling USB tethering.
Past that everything seems to be going well, do the partition and reboot my phone,(speaking of which SD card is only detected after a reboot if I physically eject it and put it back in) all looks fine as per the screenshots

(I was told memory misrepresentation was normal) until I get to the migrate data option which ALWAYS crashes the settings app, on top of that when I plug my phone into my computer I can only see the default internal storage of my device without any added memory.
I've reached a dead end and would appreciate anything at this point, even alternatives if you'd recommend I do something else (rooting or other methods i don't know about). Below are the sources I followed for this process, thanks in advance and if I missed any info let me know.

Commands i entered by order as requested:
adb shell
sm list-disks
sm partition disk:179,0 private
And yes 179,0 IS the disk name on my phone as far as i can tell
I think that after the sm partition disk there is one thing that you didnt do. That is, sm set-force-adoptable false
After this jsut restart your phone and its gonna work most prob.
I've Samsung S3 (GT-I9300) with Omega v60 ROM (Android 4.3) and Boeffla Kernal 5.8 (3.0.101).
I was using SuperSU and in the one of it's updates, it messed with the ROOT so my device now went from ROOTED to NON-ROOTED.
My device was working normally today, and sometimes when it's loaded, the phone feels like it restarted when actually it didn't restart, and Boeffla notification says that I'm missing root which is obvious for sure.
I didn't wait for the phone to finish it's frozen status and make this restart-like thing, so I forced restart it by long-pressing the power button.
The device was stuck at the loading screen for two times until I removed the battery for like 5 minutes and then re-inserted it and powered on the phone to see that it's behaving like I've installed a new fresh ROM.
I had a long list of To-do in my GO Note widget and now I'm not able to recover this list.
Is there any way to restore the GO Note widget list ?
I was thinking that since I did't format or anything, I may access that list in a form of RAW data.
When I try to add an account as maybe I had cloud backup or something, it gives me an 403 error with disallowed_useragent error so maybe I can work my way from there.
Thanks in advance.
I have a custom android tablet and we have created an application which is used for home automation.I have installed the application in it and it works fine. I got the comments from the client saying that the tablet restarts by itself at night. I tried to catch the log by connecting it to eclipse but it didnt happend here. Will the tablet restart by itself under any circumstances ? , The tablet is a samsung ARM with 512mb ram and 4gb sdcard in it which runs on android version 2.2.
You have not provided any code, which leads me to assume the following. Unless you have the permission of PowerManager, you app has no control over the device's off/on state.
You also mentioned, on testing, you were not able to pinpoint the issue that the client talked about. This is very important information, and it helps strengthen my conclusion. Again, if the above criterion is correct (you don't have powermanager) then, it could be the clients tablet is just messed up...
The reebooting is actually a common problem:
http://forums.androidcentral.com/samsung-galaxy-tab-pro-8-4/453390-why-my-tablet-randomly-rebooting-resetting.html
Here, user B. Diddy states:
It's hard to say. Random reboots can happen because of problems with
the firmware, but can also be due to some app you installed that is
making the system unstable, or perhaps some bad bit of data that is in
the system cache. A corrupt SD card can also cause problems. Here are
some things you can try:
Unmount your SD card in Settings>Storage, remove it, and reboot. Use the tablet for a while (like a few days) without the SD card and
see if the random reboots recur. If they don't, plug it back in again,
and see if the reboots start again.
Boot into Safe Mode, which temporarily disables all 3rd party apps: Safe mode: Samsung Galaxy Tab 4 | T-Mobile Support. (I couldn't find
steps specifically for the Tab Pro, so I'm assuming the steps for the
Tab 4 are the same.) This might not be an effective troubleshooting
method if the random reboots don't occur very often, because it's hard
to expect anyone to use their tablet for several days in Safe Mode,
thus being unable to access any of the 3rd party apps you installed.
Boot into Recovery Mode and wipe the cache partition, which doesn't erase any personal data. Follow the steps in this video, and make sure
you select Wipe Cache Partition, and not Wipe Data/Factory Reset.
So, let me know if your app uses the PowerManager permission. If it doesn't you're good to go, and it is probably a faulty tablet.

I've used A2SD script to move the dalvik cache to a special partition on my SD card in order to use it as an extended internal memory. However I did it under a beta release of ICS on my HTC Desire, which does not officially support a2sd. Now I have several usability issues and I would like to move everything back to the internal memory.
Is that possible through a terminal emulator (I have SU credentials on a rooted phone)?
I've tried APP2SDGUI from the market hoping that it has reverse option, but it says it cannot start for some reason.
I know I am messing with stuff that's not supported or even tested, but if anyone knows any script / command I would like to try them out.
P.S.: Here's a link to the script I've used
Try hard reset (pressing power button and upper volume key simultaneously at the time of booting the mobile) and chose factory reset.I hope this should solve your problem.
I'm developing with Phonegap+Sencha and decided to compile the example apps to test out speed.
Anyway because I compiled with the whole library in there the app ended up being about 30mb. I'm not sure how far it got but then my computer crashed for a different reason before it finished.
I now have 128kb free on my phone previously having 23mb but no new apps or caches I seem to be able to clear.
How can I reclaim the space?
The easy, and unpleasant answer is to try a factory reset.
Another option is to use a file explorer app or the DDMS tab in Eclipse to see what files are actually present on the device that you may not see in your app manager list. You may need to be rooted for this to work.
It also wouldn't hurt, if you haven't already, to turn off the phone, pull the battery, put the battery in and turn on the phone and see if anything changed.
