It’s possible that Samsung are going to update the Galaxy S5 to Marshmallow (Android 6.0) this year, and there was even a leak when someone received an OTA update to a beta version of Android 6.0 on their Galaxy S5 but I wouldn’t hold my breath waiting.
If it ever arrives, that update will still come with all the usual Samsung bloat. Some of it is useful but honestly, I could do without it. I managed to get rid of most of that when I used a different TouchWiz based rom but it didn’t leave much free space in the internal memory of the phone.
Then a few days ago came news of a 3 year old Linux kernel bug that puts any machine running vulnerable versions of Linux at risk. That includes millions of Android phones. Most of those phones will never be updated.
With Marshmallow, Google are responding faster with dated “patch levels” so you know when it has been updated but that’s not much good if you’re still on an earlier version of Android or using an older phone that’s unlikely to be updated.
So, with my phone regularly running out of space, the prospect of more Samsung bloat, and a nasty exploit, I decided to go down the Cyanogenmod route once more.
It took about 3 hours to do, and most of that was because of backing up and reconfiguring apps. I had a head start as my phone was already rooted so first I installed Philz Touch Recovery using a handy app called Rashr that I found through this video. I skipped the first 12 minutes where he rooted his phone:
I backed everything up (nandroid, Titanium, SMS etc) and grabbed a nightly build of Cyanogenmod from here and with the help of the install instructions I found the right Google Apps package. Installation after that was a breeze, I just followed the instructions. (Boot into recovery, wipe, flash Cyanogenmod first, then Gapps).
There was one hiccup. I couldn’t get root access, even after enabling it in Developer Options. I had to flash CM and Gapps again.
The phone does feel faster, even with Facebook, Messenger and Google Plus installed now. Unfortunately Greenify isn’t hibernating them as it thinks they’re “working” but Marshmallow has it’s own doze mode that I presume is doing something.
I also have lots of extra space. With nothing else installed I had around 9GB free in the internal memory! Samsung software usually swallows the majority of that.
It’s a good thing I had that space, as Pocket Casts wasn’t behaving properly. I had it backed up so when I restored it I tried to point it at my podcasts directory on the external card. For some reason I had to set the “custom directory” to point at the directory, but then it couldn’t download new podcasts so I moved the files to the internal memory. Several minutes later and 5GB of mp3 files were moved. Luckily, when I checked the settings again, it had an “sd card” option, so I was able to move the files back toe the external card.
I had worried that bluetooth wouldn’t work but it works almost as well as with the Samsung software. Occasionally there’s a click sound, and once it disconnected when I turned on the torch.
When I first turned on the phone I used a new external sd card (just in case), and I was offered the choice of making it behave like internal memory using Marshmallow’s Adaptable Storage feature. I enabled it, but the phone said it would be slow (even though it was a HCI, class 10 card) so I reformatted it as portable storage. I then rebooted and inserted my original card.
I like to read books at night, so I use screen filter to make the screen almost completely dark. I also use Twilight to make the screen more red (Marshmallow has a feature that changes the colour temperature of the screen, but I prefer the look of Twilight). Unfortunately, and I remember this from my previous adventures with Cyanogenmod, the capacitive buttons on my phone light up whenever I touched the screen, not just when I touched the buttons. Also, the charging light would remain on when the screen was on. There’s an option to disable the notification light for app notifications when the screen is on, but not the charging light. Luckily I was able to disable both buttons and charging light in the settings.
The button light is an issue going back years so it’s unlikely to be changed. I think I had to use an Xposed module last time to fix it.
The only thing I miss from the original S5 software is the pedometer in Samsung Health, but I’ve been using Google Fit for some time now and that works just as well.
I really love the app permissions in Marshmallow. Unlike earlier versions of Android where you have to grant an app a number of permissions on install, you grant them now when they’re needed (well, except Internet access). When I tried to post a photo to Facebook up popped this message:
I still have a nandroid backup of my phone so if I wanted to go back to the Samsung TouchWiz world I can, but I suspect I won’t.
Oh yeah, They’re working on that Linux exploit too.
