S5 Fingerprint Scanner Not Working After Marshmallow Update

Problem: After the installation of the Marshmallow update when I turn on my phone the fingerprint scan is not operational and i have to enter the alternate password every time.  This is not how it was performing before the update.  How can I get the fingerprint scanner to be active upon start-up?  thanks.

Related Problem: Since updating to Marshmallow 6.0.1 my fingerprint scanner is not enabled after a reboot of the phone, I get an error “enter backup password, fingerprint scanner not available after restart”  I thought it was just the first time but it has happened every single time and is quite annoying since I have to turn my phone off at work. Also, when I do get in to my phone, after restart, the SD card notification comes up and gives me the option to transfer files. everytime.

Solution: Whenever major software updates are installed on a device there’s a possibility that some old software data gets left behind. This data is the most likely culprit that’s causing this problem. What you need to do right now is to get rid of this old data. There are two ways of doing this. The first step is to start the phone in recovery mode then wipe the cache partition of your phone. Once this is done reboot your phone then check if the issue still occurs. If it does you will then need to backup your phone data then do a factory reset.

S5 Contacts Keep Crashing After Marshmallow Update

Problem: i recently updated my S5 to marshmallow and my contacts keep crashing.  i have tried what you recommended, other than master reboot, and no luck.  i have also removed the battery and waited, but problem still exists.  the phone seems to be working otherwise.  any ideas? thanks! p.s.  if i do have to do a master reset, how do i backup everything so i can reinstall and have my phone be just as before, except without the contacts problem, of course.

Solution: If you have already done our recommended troubleshooting steps for this problem except for the factory reset then I suggest you do the reset. Regarding your concern of backing up your phone data you can do this by using Kies or Smart Switch. This is a free software which you can download to your computer. Once you have this installed in your computer simply connect your phone using a USB cord to the computer and have the program running. Just follow the easy on screen instructions to backup your data.

S5 SIM Card Removed Error After Software Update

Problem: My Galaxy S5 said there was an update available for the OS this morning, once it updated it then spent a while optimising apps and then restarted. It now comes up with an error message saying ‘SIM card removed’. The only thing I can do is select ‘restart’ from the error message, I can’t open any apps or even power off. I’ve tried a soft reset but this hasn’t made a difference. Help!

Solution: Try turning off your phone then take out the SIM card and battery. Press and hold the power button for at least a minute. This discharges the phone circuit and clears out its RAM. Reinsert the battery and SIM card then turn on your phone. If the issue still occurs then I suggest you backup your phone data then do a factory reset.

S5 Unfortunately Settings Has Stopped Error After Marshmallow Update

Problem: I have recently installed the new marshmallow 6.0.1 on my samsung s5. Since the first time i turned on my phone, a window shows saying “unfortunately, the settings has stop.” Then i realise that the quick setting bar at the top of the notification bar doesn’t appear. So what do I have to do?

Solution: Since this issue occured right after you updated your phone software the best course of action right now is to do a factory reset. This will delete the old software data that could still be in your phone and is causing this problem. Take note that you need to backup your phone data first before doing this step as it will be deleted in the process.

S5 Invalid SIM Card

Problem: Ever since upgrading to Marshmallow I’ve had minor issues.  I get the error message “No action required.  ID will automatically retry.  An unexpected download error has occurred.  (Code 30)” every time my phone wakes up from a long sleep overnight or on restart, and now today I got an Invalid Sim Card message.  I have no idea what is going wrong or how to fix these things.  I also get an SD card message asking me to explore it or unmount it…?  Never received any of these things prior to upgrading to Marshmallow.  Can you help me with any of these messages?

Solution: Try wiping the cache partition of your phone first from the recovery mode then check if the issue still occurs. If it does, which is very likely, then I suggest you backup your phone data then do a factory reset. This is a highly recommended troubleshooting step when issues occur right after a software update.

Regarding the invalid SIM card error I would suggest you try using another SIM card in your phone to verify if the problem is SIM card related.
