I purchased Galaxy s4 i9505 (16GB) some months ago and the first day when i opened it for the first time, it asked me for system update
( from stock i think it had jellybean , and it went to lolipop 5.0.1 instantly )
i was waiting about 30 minutes or more, but finnaly my new phone opened with latest firmware.
the first problems arrived just 5 minutes laters, when i realized that the clock app was not working.
i didnt care about it, since i downloaded another one from play store to fix this issue.
my problem was that i had extremely bad battery life and in general the phone was lagging as hell.
so finall after all this months today i thought of rooting my device in first palce, to clean up somehow unused apps and install another ones.
i did it succesfully following this guide -> ops i cant post links but you can search on youtube for -> How to root Galaxy S4 (I9500/I9505) running Lollipop 5.0.1
it worked good but after 2-3 restarts, it started saying that UI had stopped working, and there are no taskbars etc ..
i tried wipe cache partition but no luck.
any idea?
Perform a factory reset.
Hi,
My N910F has recently been acting weirdly. It either randomly reboots itself, or just freezes for several seconds when switching screens or scrolling/tapping buttons. This started a couple of weeks ago on stock 5.0.1 (this version, I think) running Emotion kernel. This was running fine for a while; I didn't flash any new mods during this time, although I did switch between AEL kernel and Emotion once or twice without much success.
Thinking it was just one of those situations that called for a clean slate; I backed up my important stuff, booted into TWRP to wipe all partitions, then flashed stock 5.1.1 via Odin (this version, which I'm currently running). But even before I rooted it once again the phone was displaying the same aforementioned symptoms, both during and after going through the built-in setup wizard. This behaviour continued after flashing TWRP and AEL kernel v8.2, which I'm currently on at the moment. If it makes any difference I've also noticed that the lower my battery level, the more often it reboots itself. The battery level also "yo-yos" sometimes, usually at lower levels.
I've uploaded the relevant logs as advised elsewhere for anyone who can decipher them, as I otherwise don't know what to look for. This includes my last three kmsg dumpstate logs (just in case it's a slightly different cause each time), as well as my logcat and dmesg files (whatever they are lol) which I got using the SysLog app.
Any help would be appreciated, and if you need any more info please let me know.
Thanks .
*bump*
I have the same problem. Help would be highly appreciated. : )

[UPDATE]: Once or twice when it's crashed as above, it would try and boot again but then reboot into download mode with the following text at the top of the screen above all the other info:
Code:
Could not do normal boot.
ddi: mmc_read failed
If I then pull the battery and turn it on again, it boots up as normal (at least until the next crash). Is this something that can be fixed with a fresh flash in Odin (or some other method), or is my phone on the way to its death?
Got the same issue + loses Wifi password after random reboot. Sent the phone back to the operator I bought it from 1 week ago and they did a repair. They replaced the USB-flex, did a firmware upgrade(?? ..was already updated to latest) and sent it back. I got it this morning and at first the phone now works fine and no more "mmc_read fail". But after some time the random reboots started again. Not so often now but still 4 times over the day and twice the wifi-password is lost and I had to retype it. Now I'm on the fence and just waiting for the first mmc_read fail" to happen before I complain and send it back for a second repair. I can not imagine this beeing beeing other than a hardware fail coming from a weak spot on the phone. I got the impression many people has the same issue and it really comes to life after upgrading to 5.1.1.
I also think the problem at the service shop ist that they just do a quick system test on a clean wiped phone and can't find the issue and think the phone is fine. After reinstalling my 200 apps and setting up my phone all over again, the workload causes the issue to reappear and I now have to ask the service shop for a deeper check. They accepted this as a warranty fix all though my phone has a knox trip (0-1)x4...
I've also faced random reboots on Lollipop. How i solved that? Simple. I downgraded to Kitkat. Lollipop still having lots of battery drains and bugs even on 5.1.1
[UPDATE]
I've decided to go through my network provider to get a replacement sent out to me, which they were happy to do after going through their line of questioning over the phone ("have you tried turning it off and on again", "did you try taking out your memory card and see if that helped", "did you try doing a factory reset", etc). They say it will get here tomorrow so fingers crossed for the replacement.
The ddi mmc_read fail has not reappeared yet..
It's strange.. Lately the random reboots are not wiping my wifi passwords anymore, but now after every random reboot the multiwindow is enabled and I've got to untick it in quick settings..
Latest: It seems that the random reboot may come from heavy account sync workload. I did have 5 Google accounts syncing on my phone + 6 excange accounts and when i disabled syncing alltogether the phone ran a lot smoother and the reboots stoped. So i deleted all Google accounts except my main account and for now thing seems to be fairly stable. I've also uninstalled all for me unimportant 3'rd party apps, reducing 3'rd party app count from aprx 200 to 150..
If things develop further I'll come back with more

Thanks fot starting this thread Jointfcfan...i am using 910P and have same issue of your post 1 and 4!!!!
Loosing hope on Samsung, it is really frustrating...
Tried cleaning cash, dalvic, reboots, on latest 5.1.1 k version...frozen all not neede games and apps ...only 1 google and 1 exchange account no auto sync
At next stage while rebooting it sometime going an error stating kernel panic and i have to pull battery to restart
Replacing USB-flex board at service shop has cured the "ddi. mmc_read fail" boot issue for good.
So to me it seems that when many people experiences this, the USB-flex board may have a built in design flaw making it a weak spot on the Note 4.
Also I found that the phone works A LOT smoother if using Nova launcher instead of TW. Random reboot count is way down and phone works almost normally. Still some lag, mostly when unlocking screen, but reboots happens only 2-3 times a day now. Still random rebooting enables "multi window" option every time..
I've also rooted the phone now using CF-autoroot. I've flashed Philz CWM recovery and using it to install Wanam Xposed. So now I can run Greenify properly in Xposed mode and automaticly hibernate apps including system apps..
NB! Be aware, flashing root and custom recovery trips Knox counter 0x1 permanently and MAY void warranty
I have also mailed my operator asking them to take in the phone a second time for check/repair, alt. replacing the phone. I guess when they did system check 1st. time without issues after replacing the USB-flex, it was done when phone was reset to factory and under no significant workload.

Try wait little more time. I must wait 20 minutes but with another situation and it boot up. Give also information about rom and kernel which you use (build version too of both) will be easy.
Did a wipe cache partition which didn't help, later wiped to factory reset via recovery mode which helped to regain the device access.
How ever the device was running on stock android on android 6. It just rebooted automatically and never came up. Though as said about factory reset helped.
The optimization took me more than 30min. I just left it and did my jogging.

Hi, recently, I wanted to download the Xposed Framework. Everything turned out to be fine until I rebooted my phone. Based on the last step, it states that it might take longer than usual (10-20 min). Well, my phone ran on for about half an hour on the screen that says Samsung Galaxy S5 and so I decided to reboot it by taking out the battery. The same thing happened and I retried it a few times before one of the tries managed to go past the Samsung Galaxy S5 Screen and showed the Samsung icon. I thought everything was alright and let it run. It ran on for about 2 hours before I decided I had did something wrong. I wiped off all my data and of course, when I rebooted it on TWRP recovery, it states No OS installed. I decided to take this chance to upgrade my OS to 7.1.1 Nougat. Right now it is still downloading and I would like advice on what to do next. Thanks in advance!
P.S Since this is my first post, i am unable to provide the link in this message, if there is a need to, I can provide it in the chat.
Hi!
First: Sorry for any miss spelling.
I successfully installed Marsmallow on my device with a weird way, but I have a problem with it.
It turns on well and I can use it (no bootloop or freeze on HTC logo).
After a random amount time, it seemingly freezes and exactly 10 secs after, it restasts itself from the HTC logo.
First, my way of installing 6.0:
I experienced the 25% error when I first tried to install 6.0 with the legit OTA software upgrade with my Europe version M9 plus (I Don't remember it's original build number, but this is a European modell). So I started the trial/error way of upgrading.
First thing was, bootloader unlock, and factory reset through recovery.
Second was finding here on xda a RUU collection for this device here
And I downloaded this one:
0PK7IMG_HIAU_ML_TUHL_L50_SENSE70_MR_HTC_Europe_1.85.401.6_Radio_1.1506V24P21.2005.0505_HT[W.T]_release_446584_signed.zip
I renamed and installed it with download mode.
I barely set it up, knowing what is my goal, and started OTA from there.
In short:
3 security update popped up for Lollipop, and then the first Marsmallow update.
It got through the 25% error, and installed without any problem, and with many update reboot.
After it booted, I checked if any more update was available and a second (security/bug fix) update popped up. (More on that later)
I did not updated thinking I got this far I might as well set it up (it is my daily driver).
I started to download my apps, but in the middle of it, freeze and automatic reboot.
I though it was okay, I continued the downloads and got into the settings to set that up... random freeze and reboot.
These happened random , not related to anything
I started to worry so I did that update.
After that, the problem remained, but less frequent and still seemingly unrelated.
What I tried:
Safe mode - nothing changed.
Factory reset - nothing changed.
First setup, then cache reset - nothing changed.
Keeping the phone's temperature low and monitoring it - nothing changed except it was cooler a bit of course.
Tried to block every possible app (even some system apps) without root access and using it a bit - nothing changed.
I tried these with the first 6.0 update as well.
This is where I need help. Any ideas what is the problem? I can post screenshots if needed.
I really like this phone despite the negative reviews and the lack of custom roms.
Thanks for every question and answer!
