Unrooted Samsung Galaxy S5 running Lollipop 5.0 randomly reboots Since I installed Lollipop on my Galaxy S5, my phone is trying to reboot itself randomly approximately once a week. But it gets stuck on the boot-up logo screen then, only showing the word SAMSUNG there.

If I don't do anything about it, the display is lit up with the logo, until the battery is completely emptied (the battery-graph will show a gap for that time later, not telling me what could have happened). This is especially very annoying at night, since I use my phone as an alarm-clock ;)

Does anyone have suggestions about it? Anything to disable that may cause these spontaneous reboot-attempts?


The phone is not branded
I did not root it
I already tried to 'factory-reset' my device
Everything worked fine prior the Lollipop-Upgrade
After several weeks of trial and error, I might have found a workaround or possible solution:

If you can get on without certain compulsory-apps, that came to your phone with Samsung's Edition of Android, you should consider disabling the following services in Android application manager:


S Health
S Voice
Samsung Account
Samsung Galaxy
Samsung Link Platform
Samsung Link Platform Connectivity
Samsung Push Service
Unified Daemon



  Note, that if you disable 'Unified Daemon' and 'Samsung Push Service', 'Samsung-Account' and other Samsung-features also won't work properly any more. Keep in mind, that 'Geo News' also depends on the 'Unified Daemon'! Samsung's backup-/restore-features are negatively affected, if you disable one of the 'Link Platform'-services, but Android's features still work as expected!


The list above contains apps/services, that (for me) are highly suspicious of causing the described problem, but for the sake of completeness, here's the complete list of apps/services, I have disabled (not uninstalled - since this would require root-access):


ANT Radio Service
ANT+ Plugins Service
b2b.hrs.android.lib
BlurbCheckout
ChatON
de.pizza.lib
Group Play
S Beam
S Health
S Planner
S Voice
Samsung Account
Samsung Apps
Samsung Billing
Samsung Galaxy (I don't actually know, what this one does, but the phone does not need it to work properly)
Samsung GALAXY Apps Widget
Samsung Link Platform
Samsung Link Platform Connectivity
Samsung Print Service Plugin
Samsung Push Service
Smart Remote
TalkBack
Unified Daemon


In the last 3 weeks, the problem never occurred again - and I'm not missing any of the features above. As a positive side-effect, there are no more lags or hangs on my phone any more...
