Flash the Samsung firmware for your tablet via downloaded firmware from sammobile matching the model number and region of your tablet.

You need to do this with the tablet plugged in and booted to download mode. Instructions on how to do this are on every download page of every firmware on sammobile website.

This should fix your problem otherwise you need to do a factory reset probably.

But why did this happen after 18 mos of use? Mine is the same, 6 minutes of optimizing.

by

The only things I can think of are:

- Bad app installation

- Android System Software Update is not optimized apps properly.

Hi Ben, I have the same situation with a Samsung 6 (cel phone not tablet), do you apply same web link shown above?

by

Samsung Galaxy S6? Same guide applies to that.

This guide is for pretty much all Samsung Devices and tablets from 2011 and newer.

The better suggestion for me is located below regarding BATTERY USAGE of the offending application...

If you have Zedge, this is what is causing it.

I had also done other updates and thought it was Android System WebView as it started right after that had updated. Then I read it's Zedge and I've had that program for almost 2 years. I had restarted phone and was again stuck on "Optimizing", but for me each time it has been a good 20 minutes.

I uninstalled Zedge and it started right up, no Optimizing. Thanks for everyone who figured this out!

Full load your phone. Turn off, disconnect from AC. Start and wait for the optimization process to come to an end. Check settings>battery for app using most battery. Deinstall that and reboot.

Update (06/03/2018)

Solution is from crackberry forum.

This is accurate, and mine was not any of the apps previously mentioned (my fitness pal), but I checked the battery and it had the most use directly after starting. I uninstalled it and now my phone starts without any 'optimizing'. Thanks!

This was SMART...(worked for me and my tablet is an RCA, so should work for ALL TABLETS/PHONES)

I went into SETTINGS>BATTERY, then ignored SCREEN and ANDROID OS (which took up the most battery usage on my tablet. The next item on the list was HANGOUTS (which I don't think I ever use). So I went into SETTINGS>APPS and tapped on it, then clicked on DISABLE. When it finished, I rebooted the tablet and sure enough, the problem was solved. I then went back into SETTINGS>APPS and tapped on HANGOUTS again and ENABLED it. I then rebooted the tablet just to make sure the problem was solved and sure enough it was.

Thanks for the excellent suggestion!

The only thing that seems to help is uninstalling the Google update on the RCA Galileo pro, but I want the Google update. Everytime it updates even though I did a factory reset, we go back to optimizing. I don't know what to do
