In my previous post, I showed you how to install CM 13.0. Now here’s a mini review.
CM 13.0 is fast. And not fast* with an asterisk used for phones that only stutter every now and then, but very fast. Even loaded up with apps, this thing screams and is very responsive.
On TouchWiz Lollipop my S5 was routinely outpaced by my Nvidia Shield K1. With CM 13, the K1 doesn’t remotely keep up.
Android Lockscreen Bug Finally Fixed
CM 13 finally fixes a bug that’s plagued every Android device I’ve ever owned: the Motorola Droid 1, Samsung Galaxy Nexus and Galaxy S5, and the Nvidia Shield K1 tablet. Across 3 OEMs every Android version from Froyo to Marshmallow, waking an Android device from the lockscreen has been a major PITA.
First of all, the power button might not wake the screen, or the lock screen may take a while to appear. When it does appear, it may simply not respond to touch input for a while, or be so delayed at doing so it messes up pattern unlock. Finally, the delay between a successful pattern entry and the lockscreen clearing is often multiple seconds. Sometimes the device will fail to wake entirely and has to be rebooted.
CM 13 is the first Android build I’ve used to NOT have this issue. I can’t help but wonder how CM managed to get right but Google, Motorola, Samsung, and Nvidia couldn’t.
No More Lockscreen Privacy Violations
TouchWiz Calendar will plaster your lock screen with event notifications even if you set your lockscreen to not show any notifications. Even worse, the fullscreen notification reveals other app notification icons (thankfully not content).
CM 13, on the other hand, actually respects lockscreen privacy. No notifications means no notifications show up, PERIOD. Which is exactly how it should be.
Pattern Unlock Now Displays Lower on the Screen
Not sure why no other developer thought of this before, but putting pattern unlock smack in the middle of a 5.1″ display was never a good idea. CM 13 mounts the pattern in the lower half of the screen so you no longer have to stretch your thumb or fumble with the phone to reach it.
Seriously, why didn’t anyone consider that before … it’s baffling.
About the same or less than TouchWiz Lollipop, but RAM consumption is largely irrelevant on Android anyway.
I had 10.54 GB of 16 GB free after CM 13.0 installation and 5.21 GB free after 100+ apps installed. IIRC TouchWiz leaves you with barely 8 GB free and then even that fills up rapidly, probably due to some combination of Samsung’s custom ART implementation and the fact that TouchWiz duplicates apps in the system.
This is isn’t totally surprising; bad things generally happen when hardware OEMs develop software and Samsung is no different. For all of TouchWiz’s great features – most of which have some CM equivalent – its performance on the S5 was never this good.
Samsung (and LG and Sony) lied to us. There is absolutely no slowdown from using adoptable storage IF you move your data to the SD card but keep your apps on eMMC. As shown in the previous section, there’s plenty of space on the latter for at least a couple hundred apps. Used in this manner, adoptable storage is the phone equivalent of keeping your Program Files on an SSD and moving your document libraries to a slower HDD in Windows.
Samsung and every other OEM that denied us adoptable storage for performance and user confusion reasons lied to us.
Excellent Root Implementation
No futzing with SuperSU here. Root in CM 13.0 is managed by a simple, self explanatory toggle in Developer Options. You literally couldn’t ask for a better setup. It makes you wonder how/why the feature isn’t a part of stock Android.
Word in forum threads is that this is bad, but I’ve had zero problems with it so far. Bluetooth functionality and call quality is excellent.
Much longer than stock – like “Go make a sandwich” long – though this may be due to me having adoptable storage enabled. The OS also takes a longer time to detect and initialize the SIM card during boot, resulting in a “No SIM card” error being displayed in the notifications. The error goes away once the radio initializes and before startup is complete.
To put it mildly, if you use your phone primarily as a camera (I don’t, and I rarely take pics) CM 13.0 will be a huge disappointment out of the box. The native Google Camera absolutely mangles pictures and can’t seem to focus on anything properly.
That said, Camera MX takes pics that are pretty close – if not absolutely as good as – stock.
Nearly 4.5 years later, audio volume is apparently still an issue with AOSP-based ROMs and Samsung hardware. You can boost the volume in apps that have that feature, such as Player FM, but speakerphone during calls is low enough to make listening outdoors with passing traffic a struggle.
I don’t use my phone for calls much so I don’t find this a dealbreaker, but if you depend on your speakerphone in noisy environments you might.
It’s unclear as to whether this works, but AFAIK it’s only possible with other Verizon or AT&T users who also had phones supporting the feature. None of the people I talk to frequently fall into that category and call quality is excellent otherwise so I don’t mind its absence.
As far as I know, there’s no way to change the display mode, so you may be stuck in the oversaturated Dynamic mode.
External Downoad Speed
Seems slower. Not enough to make the phone unusable, but definitely enough to be noticed. LAN file transfer speed, however, is unaffected.
CM 13 is worth it for the mindblowing performance upgrade alone. I cannot overemphasize how much faster my S5 is with it compared to TouchWiz. If you were considering replacing your S5 because of the latter, CM might give you a year or more of phone usefulness. The only flagship shipping with an OEM ROM packing features equivalent to CM’s is the nearly $700 HTC 10, so CM will save you quite a chunk of money too.
There’s so much here that makes the OS a joy to use and will make you fall in love with your device all over again. CM is absolutely the best mobile OS I’ve ever encountered. Install it as soon as you can.
