Security Updates

As of February 2016, the SlimRoms team has stopped updating SlimLP with security updates. I have decided to continue updating SlimLP, but only with Critical security updates from the Android Security Bulletins: https://source.android.com/security/bulletin/index.html. Please note that I am only updating Critical updates, not High, Moderate, or Low security threats. I am doing this by hand and may miss one update. Please be advised that this rom is not as secure as Marshmallow roms that are kept up to date. I am doing my best, but I may also be a little behind the bulletins. Please be patient. I decided Critical updates were better than none, but I can only do Critical updates, as this sometimes takes editing over 800 files per monthly bulletin.

Camera

Every now and then, when I use the built in camera app, it will take 2 or 3 pictures, and then the camera picture button will be grayed out, and you must exit and re-open the camera app to take more pictures. This does not happen with Open Camera app, which is available online or at the play store. Overall the camera seems to be working great, I'm not sure why the built in app sometimes has this issue.

GPS

GPS seems to take an unusually long time to get a fix, even outdoors in the open sky. It does work and stay locked for me, but I thought I would share, in the event others noticed this as well. [MENTION=4562849]redx64[/MENTION] has pointed out that you can speed up the GPS by downloading GPS Status and toolbox and use fastergps to update your GPS config file to your region.

Gapps or no Gapps?

For those who do not wish to install, or who are prohibited from installing Gapps, there are some great alternatives. Aptoide works really well in general, and I did take some time to test it with this ROM. As for my apps, Aptoide had all but 2 of the apps I use available, and many alternative apps as well. If you wish to forgo Gapps, but still want a login, app searching, automatic updating (or not, depending on your settings), user friendly tool, then you might want to give Aptoide a try.

The best way to use layers successfully with this ROM:

After doing some testing of the layers on SlimLP, I learned a few helpful tips.

1. The PlayStore Layer Manager App is too "new" for SlimLP. The 4.+ version available from the PlayStore will not let you undo the layers, and hense you cannot go back to stock. Use this older version (3.5) instead, which allows you to install, apply, delete, and undo changes:

2. The PlayStore layers themes are often incompatible with version 3.5 of the layer manager app. Don't worry though, there are tons to choose from here on XDA:

This Mega thread has tons of them to choose from. If you want these, only download the ones that are zip files for best compatibility. The zips should show up in your download folder, which you can move anywhere and use from the app.

The app has an option to "delete" layers, which actually means "undo" that layer, not actually delete the zip file.

If you still wish to use the PlayStore app and themes, keep in mind that you cannot "undo" your choice of theme. And sometimes themes have an undesired side effect. Two themes from the PlayStore that I have successfully used were BluSky theme, and Elixium theme, both of which worked well, with the exception of the systems -> battery settings chart looked funny.

If you use the themes, I highly recommend doing a TWRP backup first, to make sure that you can always go back!

Governors:

If you want to save battery life, I recommend that you use the "No-frills CPU Control" app and set your Governor to something like Powersave or SmartMax, and your I/O scheduler to Noop. This may affect performance slightly, but will save on some battery power.

If you want to increase performance, I recommend that you use the "No-frills CPU Control" app and set your Governor to Lionheart, Ondemand, or Performance, and your I/O scheduler to CFQ. This will boost performance slightly, but will have a negative impact on battery power.

Powersaving <----------> Performance:

Powersave, SmartMax, Conservative, Interactive, Lionheart, Ondemand, Performance.

Fast Charge:

To use Fast Charge, you must enable it in the Kernel Adiutor app. If you want to set custom settings, you will need to get another app from the Play Store, such as Device Manager or other apps that allow you to control the fast charge settings. Note that some fast charge settings apps do not change the appropriate values to function. The lockscreen may still say "slow charge" as the rom itself does not natively support fast charge, even though the kernel does.

Also, if you have any questions or comments (even if you didn't like it) about this ROM you are welcome to post them in this thread. SlimRoms is not for everyone, since it is rather "slim". No sense starting a Q&A thread for this ROM when we already have a thread here...
