Recently I remember someone had made a post asking about apps that "unlock special things" on android, and this post is for all of you who want to unlock your android device to the max!
I wanted to share the link to the repository for each app but besides I'm tired of writing, there are apps that have migrated to Gitlab (like Droid-rec) and then back to Github and I really can't find the link to their repository and I really don't want to create a mess of missing links that don't work and apps without links to their repositories! If someone has time and manages to find the repository of each app please add it in the comments and I would really appreciate it. If you have Droid-ify make sure to enable Izzy's repository and you will be able to see absolutely every single app in this list.
AutoMute: Have you ever been sent a moaning video or opened a noisy video/audio and forgot you had left the multimedia audio on max by mistake? AutoMute allows you to mute your device's multimedia audio after a certain amount of time, and has different settings to customize.
Droid-Rec: Droid-Rec is undoubtedly the best app to record your screen on android, besides being considerably customizable it has the great feature of being able to record the internal audio of your device, unlike other apps that you need to use the microphone of your device for that and the audio ends up being disgusting.
Coffe: Have you ever needed to keep your screen on for a while but going to your system settings is a pain? Coffe allows you to change the automatic timeout of your screen with a single click from the tray (the buttons that appear where the notifications are) of your device, you can even make it never turn off at all.
RethinkDNS: RethinkDNS is an app that works as a VPN to provide a system level firewall (meaning that if an app has ads and you have the filter to remove ads, you may not see them anymore). Besides having functionalities to work as a proxy and a DNS changer, RethinkDNS has the absolutely great function to see the logs or pings of each app by IP, absolutely useful if you suspect that an app is doing something weird, and you can even cut its access to the internet in one tap.
OpenContacts: This app is an app that may not really fit in this list but it has a functionality that I'm sure many will love! Have you ever wanted to send a message to someone on Whatsapp or Telegram without having to add them to your contacts? OpenContacts is simply an app to manage and make calls but it also allows you to open phone numbers in Whatsapp or Telegram without adding a number to your contacts!
Termux: A simple shell for Android, basically a terminal emulator to execute commands. For me it is especially useful in different scenarios, for example, using ffmpeg to edit a video or using yt-dlp to download videos without needing a GUI.
URLCheck: URLCheck is an extremely useful app that opens automatically when you open a link, it allows you to shorten links or skip link shorteners, detect dangerous sites (you need a VirusTotal account) and even redirect your links to privacy related front-ends, like Piped.
Shizuku: Shizuku can be defined as a kind of "root" that uses the Android debugger mode to use adb commands without any kind of modification to your phone!
(IMPORTANT: To use some apps from the list below you need to have Shizuku or adb)
Droid-ify: With Shizuku active, Droid-ify (an F-Droid client, note that this one doesn't need Shizuku) allows you to activate the "Shizuku Installer" which allows you to update apps in the background or install them without interaction, just press "Install" and that's it, just like in the Playstore.
Canta: Canta is a special program in my opinion. Canta allows you to uninstall any app from your OS and gives you labels telling you if it is recommended to uninstall it or not, and also most apps have a description about why it is recommended to uninstall it. In my special case using a Samsung device I got rid of all Samsung bloatware and I can swear that my device is at least 30% faster overall.
aShell: aShell is an app that allows you to launch adb commands directly from your phone without the need to connect it to a PC, very convenient in my opinion.
LogFox: Have you ever had an app that crashes indescribably and you don't know why? LogFox allows you to save and record the logs of your whole system, including the apps you have installed and you can even set filters to save logs about a specific app and share it with its developer (you don't need Shizuku either, but you need adb and with aShell you can access it).
SystemUI Tuner: This app is an absolute gem that I never heard anyone talk about! It allows you to customize parameters of your android that your manufacturer doesn't let you, for example and for me the coolest: Move apps to SD memory.
SaverTuner: This app allows you to customize the battery saving mode of your device with different saving modes that really save a LOT of battery.
(Like logfox, you need an adb command for this app)
Shizuku opens your device to a wireless install. Sure the default mechanism requires a confirmation of pairing, but this is a vector of attack. Additionally, you will have a small server running, potentially 24/7.
Regular users should NOT be using this!
Yeah, Shizuku opens up a massive attack surface through ADB. ADB can do a lot to your device without you even realizing it in a lot of cases, and you're basically giving ADB access to Shizuku itself and any apps that use it (which could be exploited) at all times, so its very risky. Its pretty dangerous and definitely best to avoid an app like this.
