Is there a way to hide "mail sync enabled long press to hide" notification using Mail for Wear in standalone mode?
 
New addition to the list fellas! Have a gander:

Big Font (Play Store): This convenient app allows you to change the font size to any size you want. It's available for in phone play store but can be side loaded to your watch and confirms working. Useful if some apps are giving you visibility issues but you don't want to run an ADB command every time. Highly recommend!

I found an app that can be side-loaded onto the Galaxy Watch 4 that helps will cleaning junk files, boosting ram, and even claiming to cool the cpu.

Galaxy Clean can be downloaded straight from the playstore and extracted with Wear Installer 2 to be installed directly onto your watch.

About Galaxy Clean (from playstore)
Is your phone always run out of storage? Always heated? Battery life always short? If so, Galaxy Clean will be a good app indeed. Keep your phone run fast and personal information safe.

----- Features of Galaxy Clean -----
Clean your phone junk
- Delete cache files, installers, temporary files

Speed up Your Phone
- Enhances mobile device speed by optimizing memory use

Save battery power
- Turn off useless background applications to save phone power

Mobile applock
- Applock that protect your private data

Manage notifications
- Help you deal with your notification easily

!! NOTE: I would still use Google Files Go to manage apps !!

!! This app is useful for clearing caches and boosting ram of watch !!



How to use Galaxy Clean on Galaxy Watch 4
1. When you open Galaxy Clean for the first time, give it the usual permissions it needs from the watch to clean your files.
2. The scale is kind of small with this app. Only features you need to work with are Junk Clean and Memory Boost. Click on either of these and Galaxy Clean will scan for files/caches to clean, and will boost ram by as much as 198mb (per my tests).
3. If you try to swipe/scroll upwards, you will reveal the CPU Cooler feature, which can be used to cool the watch's CPU down. (Tested this, and Galaxy Clean claims to cool my CPU down from 41°C to around 33°C)
4. All other features are pretty much broken on this build. But I still think it may be useful for the Galaxy Watch 4. :)

Download Galaxy Clean (Version 1.2.0)

speed up or optimiser apps, that claim to boost memory (randomly killing them) are almost universally a very bad idea

theres a word for them...snakeoil

I'm getting the Galaxy Watch 5 Pro (hopefully tomorrow with shipping times). Does anyone know if these same things work for the 5? I use G wallet with the bottom button almost every day, I'll miss that big time if I don't have it! Thanks!

Yeah it just won't open. Does the open animation then crashes back to the app drawer. The work around was to use adb commands, but that defeats the purpose of trying to do it with an app untethered.
okay I believe the problem must be the version you're trying to sideload. As mentioned not from me at the beginning of this topic the apk to work to the watch must be armeabi-v7a. I have bought the app and I can't share. maybe search somewhere else for older version?

While the feedback is appreciated, unless i hear feedback from others saying this does offer good results, we'll just leave it as a comment. As someone in an earlier comment said, these types of apps are like snake oil and you really don't know what you're getting or what they're really doing. On GW4 that suffers from poor battery life, I imagine this only worsens it.

Can you share what version the one you're using is? The one that works on watch.

    Wear Mail (Watch) (Phone): This is an older standalone/companion email client designed for Wear OS that's available on the mobile Play Store but not Wear OS Play Store. You'll have to extract the Wear OS apk from the mobile apk using one of the sideloading apps I listed below or download it directly from the Google Drive account I linked for your convenience. It's still the best email app available for GW4 and includes linking to all the major players (Gmail, Outlook, Yahoo, etc). It can do all the basic email functions you'd expect for an email app. Honorable Mentions: Wear Messages, Wear Photos, Wear Videos, Wear Calendar, and Wear Wifi
    Very pleased to have Wear Mail on my Watch 4 LTE, being able to use Gmail independently on my watch. Only thing I had to change is getting the phone apk from an independent app store, as regular install did not work for Samsung S21 Ultra. Thanks a million @bingblop

    Believe me when i tell you i tried everything, including paying for it...no bueno, and you will find others who went through similar hell
    There is actually a really good free app called fair mail
    that works really well. Can confirm that its standalone and requires you to sign in on the watch. I recommend using app passwords on your google account and use adb keyboard to input your email and pass via adb.

    Edit: BONUS its open source so u dont have to worry about the dev stealing your passwords

    I am not having bluetooth connection issues with either the Watch 5 nor the Watch 5 Pro so couldnt answer if it helps or not.
    The last time I had bluetooth issues was with the Watch Active 2, but I had my data backed up and did a reset and restore and all was well. Maybe try the same?

    In regards to the watch when removed from your wrist, yes that behavior is correct.
    For me I strive for the longest lasting battery possible without sacrificing the necessities of its use. Getting vibration patterns and dings will take battery life so kudos to samsung for this default behavior.

    When I take off my watch I am either charging it or am working in filthy situations and dont need the watch. I have worn the Watch 4 and Watch 5 while swimming, showering, in the pouring rain and other more concerning situations for watches from my time like the Swatch or a Casio Digital with calculator (LMFAO, I did own one and busted it playing with one of those static electricity globes at the museum).

    My favorite addition as well. Gmail not being available on these is ridiculous. Thankfully, despite being dropped by dev some time go, the app still operates with 100% functionality as a companion or standalone. Really glad I could help.

    It's too bad several of the other Wear Apps by that Dev either don't work or Googles Security Policy updates has barred using Google Account with it such as Documents, Photos, and Videos. Having Google Drive access in those apps would've been the full package.

    I wonder if anyone can disable the security risk blocking signing in on these apps? They're still the best if we can log in.

    I hope Meta moving a step on WearOS - the capability of taking Whatsapp calls on the watch from the 2.22.19.11 beta - can be seen as a step in the right direction of more to come. I also sideloaded the 32bit armv7a version of that beta onto the watch, run a newer beta on the phone. Being able on the phone to send up to 2GB documents nice side effect, but one has to keep up with new regular releases overriding the installed beta.

    SIDELOAD LIBRARY
    COMPATIBLE WITH GALAXY WATCH 5
    APKMIRROR
    Note: Considering taking down the GDrive links soon. They served their purpose and have been getting complaints about broken GDrive links. The apkmirror links are available here as well as the version numbers to do your own search for the APK if needed. Also, since Galaxy Watch 5 uses the same architecture and framework, everything here will be just as applicable.
    Google Assistant GO v2.8 (ApkMirror): It can do all the important functions you look for in a voice assistant such as phone calls, messaging, app launcher, smart home control, reminders, timers, alarms, perform searches, and is as good as it gets when it comes to answering questions. In terms of a workaround, it's really good and much better than the Wear OS Bixby which is essentially useless. This is the best option not just for GW4, but for all Wear OS given the current state it's in.
    OFFICIAL GOOGLE ASSISTANT NOW AVAILABLE FOR GALAXY WATCH

    Google GO v1.7 (ApkMirror): Best way to use this is as a portal to quickly perform Google Searches and open links in your default browser. It can display quick search results without having to open any links (Weather, Dictionary, Tracking, Etc). It's essentially a stripped down version of the Google App. Newer versions will open links using a Chromium style browser which will crash on your watch unless you also have the Chrome browser app installed (listed below). Older versions will launch links in your default browser app.

    Google Chrome for GW4 (XDA)(Google Drive): This version of Chrome is listed in the XDA Google Assistant for GW4 Mega-Thread. It works well Sideloaded but I'm not sure if it's just an older version or also modded to not crash on GW4. This is my go-to personally.

    Messenger Lite v18 (ApkMirror): Fully functional Facebook Messenger. If you use Facebook Messenger regularly, this app is a mandatory must have on watch!

    Facebook Messenger (Wear OS) (ApkMirror): This is the official Facebook Messenger Wear OS plugin that comes preloaded on some brands that use Wear OS (Not Samsung). It's extremely lightweight and offers a very nice interface designed for watches when you tap "Open App" from a received Messenger notification. It's a convenience that you can install and then forget... It's difficult to explain but I use this and the Messenger Lite app listed above since this is only a plugin that operates as a system app with limited functionality but it's the best at what it does.

    Facebook Lite v49 (ApkMirror): This version works exceptionally well. No bottom bar blocking screen and includes dark mode. It even has it's native Messenger interface that looks amazing and gives you the option to load Messenger Lite or stay in the app. You don't even need Messenger Lite if you have this app and don't mind a couple extra taps to get there. Includes Marketplace, News Feed, profile editing, and all the other features you care about without the ones you don't.

    YouTube Go v1.22.54 (ApkMirror): Found a YouTube app that's 100% functional and looks AMAZING! The version I posted works excellent compared to others I tried. It's almost like it was designed for round screens. Also verified that it has no problem playing videos.

    Google News v5.5 (ApkMirror): Compared to what's available on the Play Store, this app has no competition. The display isn't perfect but you'll have no problems accessing all content within the app. Several versions don't work but I posted and included a version of Google News that verified does work.

    Google Translator (Google Drive): This is the old Translator app that used to come installed on Google Wear OS watches. It works perfectly. Very hard to find.

    Google Home v2.7.21.2 (ApkMirror): After extensive testing with various versions of the APK, I can confirm v2.7 is the best version currently for GW4. I was surprised by just how well this app integrates into GW4. If you use Google Home then this is a must have for your GW4!

    Google Files Go v1.0.19 (ApkMirror): Excellent file manager for your watch that includes an app manager, automatic junk removal, and cache cleaning. You will have to lower your DPI to dismiss the initial dialog upon installing the app. Newer versions work too with more features at the expense of performance and visibility.

    Wear Mail (Watch) (Phone): This is an older standalone/companion email client designed for Wear OS that's available on the mobile Play Store but not Wear OS Play Store. It's the best email client available Wear OS and includes syncing to Gmail and several others. It can do all the basic email functions you'd expect for an email app including sending emails from watch UI.

    Working Wear Apps By Appfour
    Cloud Access Disabled For All Apps Below
    Wear Messages
    Wear Photos
    Wear Videos
    Wear Calendar
    Wear Documents
    Gallery Go (ApkMirror): Lite version of Google photos for easy offline management and editing of your photos and videos. This does not sync photos between your devices. Only download if you store photos on your watch. Note: Wear Photos works better and is located within the Sideload library!

    Spotify MOL (Google Drive): A modded Spotify Lite version. I've tried several modded Spotify apps and this is the best one I've found. It can play anything from your Spotify premium account directly from your watch as a standalone. You don't need your mobile device at all.

    GW4 Remap (Download): This app is new to the scene by XDA user BigBoot93 and packs a huge punch that I think ya'll are gonna want. With the release of this app, we can now Remap the Bixby and/or Samsung Pay shortcuts to Google Assistant Go or Google Pay respectively. That's right! How it works is when you long press the hardware button, the app of your choice will override the built in app and launch over it. For the Bixby shortcut, it's highly recommended you change your settings to open the power menu instead of Bixby when long pressed. Then configure the app to launch Google Assistant whenever the Power Menu is shown. It's the best option for overriding Bixby hardware. This should help until Google releases an official version of GA for Wear OS 3.0. Update: Ultimate Alexa was just added to the list of configurable apps.

    Big Font
    (Play Store): This convenient app allows you to change the font size to any size you want. It's available for in phone play store but can be side loaded to your watch and confirms working. Useful if some apps are giving you visibility issues but you don't want to run an ADB command every time. Highly recommend!
    Recommended By: puredp1 - Thanks!
    Discord v40.8 (ApkMirror): Works good enough to use on watch but it isn't ideal for round screens given it's layout. This is fully functional if you're patient enough to mess with it.

    Instagram Lite v200+ (ApkMirror): Old versions crash. It doesn't look the greatest but it's fully functional. The problem is that the bottom status bar covers 20-25% of the display with blank white space for some absurd reason. Unless you use Instagram often there's no reason to bother with this.

    User Recommendations: Google Voice and Google Hangouts (Have not tried personally so I don't know).
    NOTE: You can lower your font size to optimum viewing by using the following ADB command: adb shell settings put system font_scale 0.80
    ---Can replace 0.80 with any number. Normal size font uses 1.00.


    Apps Used For Side Loading
    Bugjaeger (Link): My personal favorite. Good for any ADB related action that you could possibly need for side loading including bundled installation. Do not prefix commands with "adb".
    Easy Fire Tools (Link): Basically the same thing as Bugjaeger with a multitude of other features that could be considered useful or useless depending on the user.
    Wear Installer (Link): Good app for quickly extracting the companion Wear OS apk from the mobile companion APK since several outdated apps aren't included in the Wear OS Play Store. Can save the APK or install directly on your watch. No command input functions however.

    Using ADB Commands To Sideload

    Change DPI
    adb wm density xxx
    Display Current DPI
    adb wm density
    Reset DPI
    adb wm density reset
    Install App
    adb -e install <filename.apk>
    Uninstall App
    adb pm uninstall -k --user 0 <package_name>
    Customize Font Size
    adb shell settings put system font_scale x.xx


    OLD vs NEW
    The Best place to download various versions of ANY apk is ApkMirror. Some APK versions have multiple variants available. Only armeabi-v7a "Arch" types work on Galaxy Watches. The reason newer versions of apk's developed for mobile phones don't work is because most newer versions use armabi-v8a arch types for compatibility with newer models. However, Galaxy Watch 4 doesn't support v8a. For DPI, use nodpi for best results. Super old versions of an APK have a high likelihood of no longer working with any device due to outdated files, authentication, or security protocols. Test it on your phone first. Just bounce around the hundreds of available versions available for most major apps until you find one that works. Newer versions have more features (which may or may not work), but older versions have a more fluid and visible interface on watches. If you're trying to use an app that uses WebViews or Chrome Custom Tabs, it will crash on watches unless you install the chrome browser app I listed above which gives your watch the ability to use Chrome Custom Tabs.

    DISCLAIMER
    I did not create or develop any of the application content within this thread, nor am I in association with any of the developers that did. There is absolutely no monetary compensation for myself regarding anything in this post. My intent was to create a free public library of available content for Galaxy Watch 4 because I knew it would be useful. Everything here has been tested by myself by searching high and low for the best apps I could find and testing each one extensively on my own GW4. I experimented with various versions of each apk to confirm the best compatibility. I'm simply putting together a library of what I confirmed works good enough to sideload. If you know any other apps that aren't included in this list, please share below!

    List of additional APKs that can be Sideloaded to your watch by Appfour developer (Extracted from the phone app version). These apps are wear apps but were removed from the wear side of the play store.

    Wear Messages: Syncs to Default sms and Facebook messenger.

    Wear Mail: Provides standalone or companion access to Gmail and various other emails. Full email functionality.

    Calendar for Wear or Calendar W: 2 of them included. Both can link to Google or Samsung calendar account. I prefer Calendar W.

    Wear Photos: Standalone or linked app that can view all the images from your phone.

    Wear Video: Standalone or linked that can view all the videos from your phone.

    Wear WiFi: Great Standalone Wi-Fi manager. (This app is available on both play stores, no need to sideload).

    Those are all the appfour apps that I have installed that WORK. All the other ones don't work so I didn't include them like the YouTube or Document viewer.

    I highly recommend the Email if nothing else.

    Note: Wear Mail was too big to import at 7mb so I had to zip it first.

    Also: I attached the old Facebook messenger addon that wear OS used to have installed. It can't open messenger directly but when you receive a messenger notification on your watch, there's an option to "open app" which will then open a messenger interface that is designed for wear OS with full functionality.

    I had to get an account for XDA because I could not go without thanking everyone here for making my galaxy watch 4 something I am satisfied with. I love the hardware of this watch, but the lack of some applications left some to be desired. I really appreciate you all!

    I have tried to install different versions of GO Assistant with no success. The 1.x versions do not even start (the loading circle remains). The 2.x versions start but then he doesn't "hear" me when I speak (even if from the interface it is listening and I obviously gave permission for the microphone).
    Which version have you installed successfully?
    For me it was 2.8

    "wm density reset" to go back to default value. You're right , it is 340. I did a reset and used " wm density" to display it
    Thanks, this is the key info I had been missing. (I was too scared to try and adjust the resolution from other threads because it wasn't complete enough). I already had BugJ installed on phone from when I sideloaded Go. Process below (I omitted the part where I validated the default was, indeed, 340, before I changed it).

    Turn off bluetooth (connections menu)
    Turn on wifi (connections menu)
    Turn on ADB debugging in developer options menu
    Turn on debugging via wifi
    Back out of that menu
    Go back into developer options to get IP address
    Go into BugJ and connect to that IP address
    In BugJ go to the first tab (commands)
    Click on the "+" icon at top
    Add a command that is "wm density 200", name it something like "wm" and save it
    Go back to first tab, scroll to bottom to find command added (wm) and "play" it
    Go to watch and activate Assistant Go, see tiny text, click on blue box, then again on next screen, this will dismiss that junk on the bottom of Assistant Go.
    Go back to BugJ, edit the command to be "wm density 340"
    Play that command
    Go to watch, activate Assistant Go and confirm screen res is normal.
    Exit BugJ
    Turn off Debugging on watch
    Then turn off wifi and turn on bluetooth

    Celebrate!
