Why is my S4 i9505 randomly rebooting after rooting? - Galaxy S 4 Q&A, Help & Troubleshooting

I rooted my phone a couple of days ago using cf auto root. I haven't flashed a custom recovery yet. I deleted 1 systen app which was the YouTube app so i could install a better version. Then my phone randomly did a quick reboot. It went to the spinning samsung logo and then to lockscreen. It took about 15-20 seconds. It skipped the samsung music that usually plays during boot and skipped the screen that says samsung galaxy s4 gt i9505. And, sometimes the home screen just freezes until i go to a different application (like settings) or holding the home button. Since i rooted, these random reboots hav happemed about 8 times. Today it happened about 2 or 3 times. I've noticed that is triggered when the screen is powering off when i press the power button or after a minute of inactivity when it automatically dims and then powers off. But it doesnt happen like this everytime. However, one of them happened was while i was talking to someone on the phone.
A couple lf people have said that installing the latest firmware on my phone will help. But isn't there any othet way to fix it?
Why is this happening? What is causing this? Will this problem go if i unroot?

S4 gone crazy. Please help.

Hello, I am Not a noob at all when it comes to android phone but i have this funny and weird problem. Phone starts to get to dock mode when i havent even connected it to dock.
Then after pulling the battery it. Is got stuck in the dock connected and disconnected loop making the phone unusable.
On the second restart I did, it then started playing music from my music player. Even when i close the app. It again starts to play the music automatically.
After that, the phone switched to vibrate. As soon as i preess the vol up key, it goes back to vol down and goes into vibrate mode
This is very frustrating as I have 0 rogue apps. No malware etc. I have the latest MG1 indian rom via OTA.
Anyone else experienced this?

As someone familiar with Android I take it you've already tried factory reset or re flashing stock firmware?

[Q] Note 3 hanged

Hi guys,
Anyone encountered your Note 3 hanged and you unable to swipe or press the back button.
The only way to swipe again is to press off and on and you be able to do that.
My phone is brand new and even after I factory reset it still hanged.
Same Hangups with me
The same happens to me with an unchanged Note 3 9005, Vodafone Germany branded; Suddenly the especially the screen freezes.
some buttons still work. Sometimes it works again, sometimes only a reboote works.

And i thought it was a launcher that causing this. Seems like I'm not the only one.
Note 3 hanged
I use the Nova Launcher ...
Anyone facing the same issue?
anyone? no one having this issue?
My T-Mobile Note 3 did it once, so far.
NOT rooted, stock launcher and browser.

Yes, same problem here with a completely stock and non-rooted international (Germany) Note 3. I have had the device now for a little over a week, and the problem occurs quite frequently several times a day. Very annoying, so any fix would be VERY appreciated!
German Unbranded LTE... Apex Launcher, no such issue so far.
Try cleaning your system cache in Recovery.
I get the same problem.
No response to back, menu, home or power button.
If I wait about 10-20 seconds, it will start responding again.
It happens several times a day.
Very annoying. Never had this problem with the Note 2.
N900 in Thailand, not rooted using Nova launcher.

I tried this yesterday, but I'm afraid it didn't fix the problem. A couple of hours after cleaning the cache partition I got the next hang.
I gave up on this and decided to ask for a replacement phone. Bummer.

My non-rooted N9005 crashed several times as described below. However I can't replicate them on purpose. It just happened randomly.
On boot-up, when the lockscreen is shown, the device keeps restarting on its on, non-stop. To resolve, I'll need to quickly unlock the phone when the lockscreen is shown. Sometimes it would just keep restarting before the locksreen is shown. When this happens, I'll need to remove the SIM card and the phone would start normally. Then turn it off, reinsert the SIM card, boot-up and quickly unlock the lockscreen. This occurs randomly, but when it occurs, the would keep restarting. Else, phone would boot-up with no issue.
Recorded a video and stopped the recording. Camera hang. From then onwards, can't use camera until reboot.
Enabled the "one-handed operation - use for all screens". Switched to one-handed mode. Not sure what happened, but camera was started when I exit camera, screen is reverted to fullscreen. It should remain in "one-handed" mode. Touch responded to area where the "one-handed operation" window should be. No response to area outside this area. To resolve, re-enter "one-handed" mode and exit.
Phone just hang when games are started which the audio loop playing repeatingly.
My Note3 got hang when I was using facebook...
I m curious it related with RAM... when I check the RAM (after it responds again) it was 2,4 GB of 2,66 (max available)..
After I clear the Memory, then problem stops...
Same issue here..
i'll be scrolling facebook or browsing and i cannot click on links or scroll
weird thing is i can press the back button to close the app or the home button..
there are some other major glitches as well such as Gallery opening VERY SLOWLY.. quick pic is my work around..
waking up the phone with the power button takes longer then expected as well..
coming from a Z10 with less specs and listening to people bash it.. the 3GB quadcore Snapdragon 800 chip with 4.3 jelly bean is deeming to be disappointing..
don't get me wrong i love the device.. just didn't expect so many glithces and slow downs and hangups
Same issue on exynos.

I tried something new today, I've been clearing the Ram memory every 15-30 minutes of constant usage and every time I start using the phone and it seems that I haven't had that problem yet. Makes me think it is related to a process.

[Q] Annoying bug - short press home key and long press power button not working

Hi,
I've encountered an annoying problem with my SM-N9005 (UK SIM unlocked - 02) running firmware XXUDMJ7 (not routed - no mods).
Periodically, the short press of the home key will not return me to the Touchwiz home screen. Long press of the home button will still bring up the task manager. When this problem occurs, long press no longer brings up the Device Options dialogue. A short press will blank the screen and holding the power button down will eventually reset the device.
Following a reboot, the device will work normally for a while until it reoccurs. I can't correlate this with a particular application being installed or used, and it occurs frequently enough to be seriously annoying.
I haven't yet done a factory reset as installing all apps will be a major waste of time. Has anyone encountered this problem and found a resolution?.
All tips or help gratefully recieved..
Regards,
Alex

No joy... overwrite with the same firmware doesn't change anything. I can't trace this to specific app to unintelligible (or not reinstall) without a few pointers.. any ideas?
Thanks,
Alex
I also have this exact problem and until I read this thread I had to keep pulling the battery every day or so to reset. At least I know I can hold the power button to reset now!
It usually starts when Com.phone.android crashes after ending a call but has also happened when the youtube app hangs. Sometimes the only way to make the screen come back on when this happens is to plug the charger in when it goes into this buggy state.
Any ideas would be great as this is annoying
Same problem here on the device of my girlfriend today. Never had this on mine (both phones snapdragon version).
Thinking of exchanging it.
Happened to me yesterday. No idea what triggered it. A reboot made the problem go away.
Maybe it's a coincidence, but my internal storage was beginning to run out due to a weird problem with the Samsung index service creating huge files for no apparent reason.

It's happened to me as well and I I'm stock not rooted. It didn't happen with my first device. But has happened with this second one. I've had freezing, crashing, blank home screen, power menu not coming up, screen not locking and few more issues. This phone on both my first and second have been so buggy I've thought about another phone altogether. So glad it's not just me. Tired of constantly monitoring RAM and closing out apps. I haven't even installed all my normal apps due to so many problems. My S3 was 10 times more stable than this phone. Note 2 definitely never had this many issues.

I'm running a MJ6 stock ROM with MJ4 baseband. It's a Three UK branded one. Unrooted.
I had quite a lot of apps installed at the time. I also had a couple of Home screen replacement apps, namely Apex Launcher and Nova Launcher, and also Toddler Lock. I enabled Nova Launcher to see if it was a problem with the TouchWiz Home app, but the home button still wouldn't work.
In addition, I couldn't get the power menu to appear. I unusually prefer to do a soft reboot via the menu whenever I can, but on this occasion had to do a hard reboot by holding the power button.
I wonder if this is related to that old Sleep of Death (SOD) issue that other Samsung phones have had. That's happened to me on at least one occasion with with phone.
I'm guessing this is firmware related. I would happily try a custom ROM to see if it solve change anything rather than bombard Samsung with tech support requests, but since they've introduced this Knox nonsense, I have fewer options to try and fix things myself. Perhaps if everyone on XDA were to adopt a policy of calling Samsung's helpdesk every time we experience a software problem, Samsung might find themselves so bogged down with issues that they would realise that allowing users to install custom ROMs probably saves them a fortune in tech support costs. (Sorry about the rant.)

Stock, Sprint MJ7. 2nd phone, last one had bad screen. The last 2 days the clock app stopped and the alarm didn't go off and then I had this behavior.
Go to settings/controls/auto adjust sensibility. Set it out and on. Problem is resolved.
I got a solution.
After a lot of beating around the bush, I called Samsung care. Explained them my inability to operate the Home Key short/single press to go to home screen. I was advised to back up the phone and do a factory reset. I did so and WOLA...... The single press on home key works now.

Galaxy s4 i337 startup time

I'm on 4.4 and unrooted. My phone has the longest startup time ever. It used to be fast and I haven't done anything out of the ordinary to have probably caused the issue. It boots normally, but then when the att logo appears, it does the little animation but then vibrates once slightly, then usually follows another slight vibrate some seconds later. This usually occurs for about 45 seconds to a minute until my lockscreen appears. I factory reset, and I tried powering off and on right after the reset. It was back to normal. However after I downloaded all my apps again and reinstated my settings, the problem reappeared. Is it simply because of the number of apps I have? I don't remember this happening before the update. I thought it was because I had downloaded and used zooper widget, but I uninstalled that app and tried the booting. It was the same duration (1 minute on att screen)
My bad. I'm on Android 4.3 *
