Hey,
Not sure weather someone else has clocked onto this but I think I've worked out what is causing the problem with apps not opening (IE loading for a few seconds and then going back to the homescreen).
I thought I would share this because someone might be able to come up with a solution.
Ok so here's the problem:
- WP7 uses Tombstoning or SaveStates, whatever you want to call it.
- When an app crashes (which is inevitable on a new platform, Android apps still crash now) the system doesn't deal with them, instead the only way to stop the 'crash' is by pressing the homescreen.
- This then leads the system to create a "SaveState" of the crash.
- Next time you load the app, the system tries to restore to the previous state, restoring to the crash, causing you to go back to the homescreen.
- This is an infinite loop.
At the moment the only solution I've found is to reboot the device. Maybe there's some way that we can clear SaveStates though?
The OS itself doesn't actually save states, it's done by the applications themselves.
The problem is WP7, reboot the device.
i thought you can only access those saved states via the back button. If you try to open it anywhere else, it would trash the previous session and give you a new one.

This was my understanding, but that doesn't mean the app cant be coded to attempt to resume.
Also, this does not apply to the OS's inbuilt apps - if you open IE you still have all the previous tabs there.
I agree with the general theory - its usually started by an app crashing - but is impossible to fix in any way except restarting, due to the lack of any task manager or process control accessible to users.
So the cause, at this stage is irrelevant - cause theres only one solution - restart.
i had to reboot my phone once when t-mobile tv crashed on me. look like someone forgot to do some garbage collection after the crash and crap sit in memory until phone is rebooted.

Does anyone else have a lot of problems with the marketplace app crashing? It seems like every time I go to the App favorites and new list, after scrolling for a minute or two the program freezes and then goes back to the main screen and won't start again.
frankly I had this problem in the first few weeks, but now its totally dissapeared. I dont know what changes MS made(if any), but I havnt had Zune or marketplace crash in the past 2-3 weeks.

Well definitely it needs update.
Mine doesn't freeze but I usually browse free apps, so in my case Marketplace crashes after few installations. Always. Have to reboot the phone to make it work again.
1. Not starting and having to reboot phone.
2. Slow.
3. Showing updates for same applications every day which don't go away.
I don't have any of these problems but what the marketplace does need is filtering when searching.
I should be able to swipe left and right to choose search results that are Songs, Apps, Games etc not just one huge list that is mostly dominated by songs and albums.

i experience these with market place. for...
1. once the market place crashes, it won't restart, so yea reboot is required. i haven't worked out exact steps to replicate, but it happens after using the market place a lot.
2. it is slow just due to the amount of information it gets. but as you can see with the update they did for the facebook app, MS has figgured out the best way to speed up the processes.
3. this will happen with apps that are trials (unpaid apps that require payment). it is a bug in the system. if you want to update it, you have to uninstall the app completely, and reinstall it. i think MS will fix this in the update.
For some times now i've been trying to single out an app that was causing the random crashes, or hot reboot
http://forum.xda-developers.com/showthread.php?t=1336896
the problem seems to cause the whole front end of the OS crash and restart itself reloading every single app as if you had rebooted the phone, but there was no reboot involved.
in the end i noticed everytime i was messing around with the mount SD cards as USB storage, and right after is when it happens the most, as well as when i swap one SD card with another SD card
everytime something related to SD card happens the annoying Media Scan will run, and because i have TONS of files, it takes a very long time to finish scanning, so if something needs access to those files, it causes the whole system to crash and reload (not reboot), and then because it crashed, it starts the media scanning process again, and if you have many widgets that request files from the SD card then well.. you get the point, it kinda goes into an endless loop
END TASKING everything sort of helps, but it's not a real solution.
can some one remind me where or which system service i can freeze or remove to kill the Media Scanner?
thanks
PS: this sort of reminds me of the old bug on SGS1 when the Media Scanner runs out of memory when your library collection is too huge for it to process
Yes the only slowdown/crash I had (just once) with this phone was while media scan was running and I was trying to access Sd card for file copy. It does run every single time you do something on SD card which is annoying.
But would it cause more problems if stopped from running?
Hi AllGamer,
Have you figured out how to stop the media scanner?

i have a good idea how, but i need time to dig out that information from the old i9000 section, and i'm very short in time with all the soap opera going on
The below is long winded, but I believe in giving as much detail as possible, as well as it's still an ongoing process for me where I believe I've resolved the problem, yet I keep forcing it accidentally and not yet exactly pinned down my issue entirely.
I just got this phone, set it up, and was running into a similar issue where media scanning would initiate and continually initiate over and over while reloading dash and not loading all widgets. My actions the other night prior to this happening were making a backup in clockwork mod, installing setcpu, setting up setcpu, copying media files from old SD card from previous phone into new external and internal SD cardm then restarting the following morning after waking up. This baffeled me, and through google searching I came upon your threads, I saw ICE Music 4.0x or IM+ apps where your issues, however I have neither app.
Traced my steps back thinking what I did before sleeping and after backing up. I started deleting media files (pictures, movies, music) off the SD cards. After rebooting, this did not resolve my issue. I then rememebered I did SetCPU. I was able to successfully uninstall the app from my phone by dragging it to the trashcan before media scanning restarted. I rebooted, however, this still did not resolve my issue. I restored my backup prior to all this since my issue was unresolved through these means, and media scanning was fine. I've not been using SetCPU the past day and everything is fine.
My analysis is that using SetCPU is fine, I was using it the other night after backup, but prior to rebooting phone, however if SetCPU is set to run on boot, then Media scanning goes all fubar. Even if you uninstall SetCPU app through the android menus or dumping to the trashcan, something still seems resident in the booting process or initially something is modified that does not become unmodified. I've yet to try manually loading and running SetCPU each instance after bootup without having setcpu set to start on boot.
Hmm maybe I spoke too soon. Since that time, I've restored approximately 10k sms messages with SMS+ Backup app, sent a sms in handcent, backed up sms with SMS+ Backup, believe I received a sms, updated AdAway app, and started/updated AdFree app, and however I don't see it now.
Now, the adfree app gave me a menu I had no recolection of on my Nexus One, where I had two options. One option I don't rememeber, but the other "Boot Normally", I remember and chose. SetCPU is not installed at this moment, and after doing just those couple things from the 1st sentence, I rebooted. I noticed that the display at the bottom would show Adfree granted superuser permissions, and then I would get a freeze and reboot of the dash. I may have setup Adfree the night before along with SetCPU (It was late and I had been up 24hrs the previous night). I've frozen AdFree with Titanium Backup and removed it from superuser permissions, but I'm still media scanning crashing again. Unsure if the boot normally option in Adfree modified something in the booting code. I'm going to try restoring with Clockwork Mod again, then do my sms restore, and see if that narrows the issue down. If it appears finem then I'm assuming it has something to do with apps that modify boot coding like SetCPU or AdFree, if they actually modify it that is. I'm not good at coding. I'm at work, unable to do much playing around, however, I hope some of this is of assistance with resolving this issue.
Got a chance to test it. My issue with media scanning appears to be too many sms messages saved. after restoring about 10k in sms's, it just media scan loops.
Hi everyone,
I have a rather sticky problem. A few hours ago I decided to disable a few of the services that I wasn't using on my phone in the hope of some more free memory and battery saving. The services where things like Stocks (including it's widgets and tools), weather, some pre-installed apps like Sound hound and a few others. As far as I could tell none were critical system services. After finishing I rebooted my phone to check the outcome....and it was not pretty....
Phone boots and everything seems to be loading fine (interface, startup apps, notifications), but my desktop is blank, none of the three soft buttons work and the only thing that works is the power button (to reboot). ah, actually the main menu (sliding from top) works, it slides down but whatever I select from it, the menu closes and nothing would happen. I assume I disabled a service that was in dependency with HTC Sense service and now that service is failing to load...?, correct me if I'm wrong.
At this point I have no clue as to what to do except to try to see if I can root the phone again, any ideas on how I can fix this without rooting the phone?
(I have no backup, no version info...nothing..., I wasn't expecting anything like this to happen while messing with non-critical app services so I did not go through the "backing up everything" procedure... sadly... )
My Fire Phone has developed an odd issue. I am hoping something more knowledgable on such matters might shed some light on what to do.
It started occurring a few weeks ago. Many apps would crash a few seconds after opening them. I figured out it appeared to only be apps that have some relationship to Contact data. SUch as WhatsApp, all contact apps, all phone apps, dialer apps, etc. Apps with no association to contact data are fine.
I ended up factory reseting the phone and starting from scratch. Installing GApps, etc., as per originally.
The issue seemed to be fixed. Sigh of relief.
Today I used the phone in the morning, and it was fine. I pick it up to use some hours later in the late afternoon, and the default launcher (which was Arrow Launcher) would crash every two seconds. I couldn't get access to the phone. Rebooting made no difference. I discovered I could still use the double-click on the home button to pull up the carosel, and there could click the system settings. After trying many things, I eventually used that method to uninstall the launcher. I had a few lunchers installed already, so I picked another launcher. The other launchers are all fine, so I thought the problem was solved. BUT when I open any app that accesses contact data it was back to the same old story... it crashes in a couple of seconds. I suspect the Arrow Launcher itself has some feature whereby it access contact data, and that's why it was also crashing every 2 seconds.
I found one other person posting what sounds like a similar issue, back in March. https://forum.xda-developers.com/fire-phone/help/crashing-apps-t3575127
Doesn't indicate what he/she discovered or did to fix it.
Can any suggest how I could trouble shoot this? I am resisting going through the lengthy process of resetting the phone again, and getting it all set up, because I already did that, and the problem spontaneously returned.
Reinstall your rom, search on amazon website
Hi everyone, I hope someone here can help me.
I'm experiencing a bug on my phone that's bothering in several situations.
Apps in landscape mode switch to portrait and come back to landscape (or not):
http://imgur.com/gallery/vfgSCPn
Voice notes in WhatsApp get interrupted:
http://imgur.com/gallery/yXIlFbI
(you'll see that the navigation bar briefly goes white)
I've factory-wiped my phone, gradually reinstalled the apps and double-checked that there are no weird or potentially dangerous apps.
The tricky part here is that I can't find a pattern, as it randomly happens (for instance, my keyboard went down when writing this actual post).
Has anyone else experienced this problem with their phone? Any idea on what I can do? It's really hurting my experience with Samsung.
Thanks!
You might try another Android version.
Clear system cache on the boot menu.
You can try a hard reboot as well.
Test the sensor(s) that controls that (it could be an intermittent failure, the worst kind to diagnose).
Does manually locking it to landscape mode stop it?
If it's a brand new phone, get it replaced as this is not a normally seen glitch.
Reloads generally don't cure settings or hardware issues and useless it's an old load or has a worm, trojan, etc are generally a waste of time.
As invariably the original issue just gets triggered again... eventually.
