Phone lost settings & device id??? - Galaxy S 4 Q&A, Help & Troubleshooting

I've been running Phoenix ROM v7.3 on my I9505 for a few months now. In the last couple of days it's started acting strangely...yesterday the home button stopped responding (it would turn on the screen, but nothing else). I tried rebooting a couple of times but it didn't help.I also noticed that some of my sound settings had changed without any intervention from me - phone ringtone, notification sounds, sounds when touching the screen. This morning I ran Titanium Backup and it told me that my device id had changed, and asked if I wanted to restore my previous id (which is what it did when I first flashed the ROM a few months ago). I answered "yes" to this, and let the phone reboot, and now my home button seems to be working again.
I know the obvious thing to do is wipe and reflash, but does anyone know why this sort of thing happens?

got a htc phone and my phone keeps freezeing i need to take the battery out then put it bk in to get my phone it keeps happening alot. took it to a shop and they say they reflashed but it didnt work any body got any ideas thanks
First of all, while the phone is working.. BACKUP all data.
Then try this...
Hardreset (I don't see any other solution).. then RESTORE data.
If the above post doesn't work, then maybe you should have that unit replaced while it's still under warranty (I assume)...
I also experienced the same a while ago. All of a sudden, after 2 weeks of using, it hung. The only thing I did was having it a day connected to the internet and loading 150 emails into the newly created account. I experienced a slower operating system, though, and the hanging of the Jade could be linked to this full inbox.
Btw. no additional software installed or tweaks. At that time, I only had NoData installed and TomTom.
For some reason, when the backlight went off, the wake up hard button on the Jade didn't function either, so I had to take out the battery every time to make a call. Rediculous...
The solution for me was indeed to hard reset. Soft resets or configuration chagnes didn't work. After the hard reset, no problems anymore...

Phone hard reset itself after hanging!

The phone hung a couple of days ago (nothing new) so i pulled the battery as I didn't have a pointy thing for the reset button. When it rebooted it came up with a red scroll bar on the windows splash screen. It then asked me what network I was on and had to be set up as if it was freshly hard reset! It had lost all emails and settings, but kept all the texts and programs, although it kept asking me if I wanted to run various component of these programs in case they were malicious!
Has anyone else experinced this?
I can't believe how unstable it is, even before this happenned I was soft reseting it daily when it hangs, usually trying to wake the phone after a text or missed call, or on the music player screen. Honestly, when it works I love it but more often than not I want to throw it at a brick wall!
Come on HTC, give us a ROM we can use day to day, this is a joke!

my HD2 did a hard reset on its own...

i had a weird problem today; i was in a restaurant and got my phone out of my pocket, and was scrolling the tabs when it suddenly froze (which never happened to me before) and became very slow.
then right after that the wallpaper disappeared and when i scrolled at the music tab it didn't show my tracks so i thought it was the SD card so i soft reset but it stuck forever at the white startup screen.
but after a few attempts it passed it (took a veeeeery long time) but the weird thing is, it didn't start the system but took me through the initial setup steps as if i was starting my phone for its first time...
but strangely it kept my email accounts (didn't keep youtube or twitter)
after it started, sense didn't launch and it kept asking for my permission to run "cht-wall" and other stuff but nothing happened afterwards...then it shows that .NET is missing...also it didn't detect my network and it set itself to vibrate!
so i cannot go to home screen but i can open and scroll start menu and go to lock screen, and all my programs are still there (haven't tested if they work though)
also, i get an error report saying that cprog.exe had an error and the message won't close...
i did a hard reset and everything was solved, but i'm confused cuz it never happened before or even heard about it. also worried it might happen again.
can anyone tell me what happened?
sorry if i wrote a long topic but i wanted to be as detailed as possible
ROM: stock WWE 1.66.415.4
radio: updated from 2.06.51 to 2.10.50 a couple of days ago
thanks in advance

Phone crash after battery died!!

my battery was running low, (and coz poor battery issues with JPY), i didnt notice when it switched of. normally i use the power button to turn the screen on to unlock, but instead i realised the phone had been off as it was now booting up...it booted up fine went into the homescreen and then vibrated once and powered down.......now it was powering down for a long time and occasionally there were vibrations and the lights on the home keys were constantly on. the screen was black. i got home and tried to charge it but the progress bar showed no progress on charging, i tried to switch it on but it would go to startup screen vibrate cupla times and power down. so eventually had to do a hard reset in recovery mode. tried every option but in the end had todo it by wiping data.
now the thing is, is this supposed to happen? if ur battery suddenly losses power ur whole fone will screw up?
for future ref if ur battery dies dont try to switch ur fone on until u got some charge in it and use the home key to put screen on..
Sounds like it could have been faulty firmware .
JPY does not have a significant battery drain problem per se .

Black screen, vibrations and no boot after restart
Hello! I had almost the same experience (Black screen after reboot and occasional vibrations) only mine refused to boot even after memory wipe and after flashing new roms.
Was your phone rooted? Because I think rooting a 2.2.1 rom (XWJS3) was the beginning of my nightmare. keep in mind that the phone was working like charm for two months. This was the second time I had a problem. The first time the phone started after performing a factory reset by itself!
In case this happens to you next time and for every non experienced galaxy player (like me) reading this:
Don't panic! Blank screen, vibrations and no boot doesn't necessarily mean a hardware problem. Finally I managed to fix it flashing eclair and repartitioning with pit512. Now I'm a happy XWJS8 user
And a question for the experts: Any clue why this happened? Is it really a rooting issue? Can a cheap Chinese battery from ebay cause this?
everything was stock on mine, no root.......maybe thats why i could recover it??!!
Maybe! and I hope the reason is faulty firmware as JJEgan says. If this is true, your phone will be fixed by the next update.
I was very urge... the same happened again. It's been a month of smooth functioning and now after a simple restart, the device doesn't boot for absolutely no reason (Stuck on black screen constantly vibrating). Since my phone wasn't rooted, and I haven't seen many people talking about a problem like this I suspect:
1. Faulty hardware (for a few devices including yours and mine)
2. A Bad app.
Contacts Vanished
Hey Everyone
Im having similar problems, i updated my sgs to the js7 version of froyo, then rooted it with oneclick method. this was as i got the phone a month ago. Its been smooth sailing since then. But last night the phone powered down and wen it loaded up it had no contacts, my sms where still there but all the apps had a force close issue none worked. so cleared the cache in recovery. Still nothing so i did a factory reset and once loaded up. i formatted the sd and internal within the settings option. So the phone was now clean. I then connected to pc luckily had backups so installed titanium restored all my apps n settings. Using kies restored my contacts n thanks to an app called sms backup i restored those.
So all was well and worked again. I didnt restore the apps i had installed within the last week to make sure it was not a faulty app. I was happy, but now tonight it did it again. No contacts again.
Pls help
Any suggestions
That's exactly how it started for me. One month after rooting froyo 2.2.1 Suddenly everything force closes and the device hard resets by itself. I reinstall all the apps and then after one month and performing a simple restart, it refuses to boot. Stays in a black screen and vibrates every some seconds. I flash a new rom but does the same. Problem solved after repartitiong and flashing original eclair with pit 512. Reflashed a 2.2.1 rom and everything works perfect (the phone now is unrooted and with a nice clear stock rom). But then after one month again (!) I realise that some videos refuse to play. Trying to restart and craaash. black screen, vibrations and no boot. Did the same again (repartitioning and flashing) and now I wait for another month to pass and lose an hour of my life to do the same again. No idea why this is happening. Is it possible that rooting messes with something that stays faulty after restoring the file system? is there an app that we all installed and caused this mess? please this is the most serious problem I've red in this forum and still a mystery. I believe this thread should be sticky and we all share similar experiences because this looks completely random!

Strange app locking and radio resets. Anyone else?

This has happened twice in the almost 2 weeks that I've had the phone (most recently today).
I'm on T-Mobile and rooted using the GS3 Toolkit v1.0 and the "ALLINONE [Flash Insecure Boot, CWM, Root phone + Install Busybox]" option. I can't remember if the first time it happened was before or after this, but I think before.
So, most recently, I opened Contacts, scrolled down, opened a contact, then the phone became unresponsive. After a about 5 seconds, the screen briefly went black, back to the home screen, and mobile data was along with cell signal. Those came back up after a couple seconds and everything worked fine. At no point did I receive a popup about an application needing to close.
Anyone else experience anything like this with their GS3 or another phone? Just wondering if I need to get a replacement or just ignore. Or maybe flash a new ROM if it's software and not hardware.
