OK, here's just a few of the best apps I've found over the years. Apps you might like or that are really useful.* This is the Good Stuff, honest. No crapware in this list. Not gonna touch games - not a gamer. So in no particular order...
AquaMail - if you ever have an urge to try another email app, you gotta try this. The best.

Google Voice - add a second line, yes, a second phone number, to your phone
for free. My wife and I have used this for business numbers for years, it's terrific. Keep your actual cellphone number private. More than just a second number, Google Voice can do lotsa stuff a ordinary cell connection can't.

Google Voice - the app, does visual voicemail, etc.

Voice Choice - automate how Google Voice dials certain people or groups. Very cool app if you use Google Voice.

Nova Launcher - There's dozens of launchers but none are better than Nova. Fast, stable, it kills. Really a must-have.

Firefox - my go-to browser.

Some Utilities:
Gotta have a good file manager. Here's 2 to choose from:
X-Plore - the best. But the 2-panel UI takes some getting used to. Free and no ads. Add access to cloud storage, networking etc for a small charge.

FX File Explorer - also very good and you might like the UI better than X-plore.

FX Plus adds access to cloud storage, networking, etc.

Clipper - super-handy clipboard utility. Clipper+ is a nice upgrade.

Google Drive - you have 15GB free storage on Google Drive included with your Google account. You might as well have access to it.

And to sync files between your PC and Drive:

System Panel - gives a lot of good information about what's going on with the phone. The free version is good.

WiFi Analyzer - analyze your WiFi network so you can setup your router to use the strongest channels with the least interference. Maximize speed of everything that connects to your WiFi.

Network Connections - utility that lists all the connections the phone is making to the internet. You will be amazed. Tap on a connection for more information, including a map. Cool just to fool around with and can be very useful too.
https://forums.androidcentral.com/e...id=com.antispycell.connmonitor&token=fgKO6OgK
OS Monitor - similar to Network Connections above. An alternative, some difference in functions.
https://forums.androidcentral.com/e...tails?id=com.eolwral.osmonitor&token=C7antSbM
PortDroid - another utility that can be useful but is kinda fun just to fool around with. Traceroute is cool, will show a map of where your connection goes to reach its destination. Amazing to see the crazy routes and number of hops it takes to reach a destination.

LTE Discovery - Good mobile network utility.

Backup Utilities:
MyBackup Pro - one of the first Android apps, tried and true. No PC needed.
https://forums.androidcentral.com/e...om.rerware.android.MyBackupPro&token=DNsUcrlw
Helium - another very good backup utility. Can backup more stuff than MyBackup, but it requires a PC.

Advanced Call Blocker - nice if you have trouble with junk calls or texts.

Other stuff:
TheScore - I just like this. But it does have ads.
