• After 15+ years, we've made a big change: Android Forums is now Early Bird Club. Learn more here.

This place hasn't been the same since...?

I remember when it was a joyful chore to meet and greet all the new members nightly when I got home from work. Twenty five to thirty five new members nightly needing assistance. Most needed help with their new Android phone and many were new to interacting on a forum format. It was a privilege to direct them to the correct area for support or to assist them in the intro section. Katie bar the door the week following Christmas. We were always slammed with questions that time of year. It was a hectic and sometimes frustrating time but we all enjoyed it... admit it. :) It would not have ever worked if not for all of you and your assistance. It seems like a great time to say Thank You. You have made these forums.


You are really welcome olbriar :)

HELP

Listen...
  • Flash the correct factory firmware (NOT TWRP or ROM) and you should be able to access the FRP password section.
  • Enter the correct pswd and boot to main OS.
  • Go into Settings-Accounts-Google and remove the account.
  • NOW ya should be able to flash TWRP and appropriate ROM..
You cannot bypass FRP until you've installed the correct FW and entered the correct pswd. Period.

One last thing: You CANNOT install TWRP or ROM in any USA model Galaxy S7 due to the fact that they are ALL bootloader locked! You actually need the International version with Exynos chips to do so. If you're on any Verizon Wireless device, just hang up any possibility of custom ROMs, even if it's a Google Pixel phone. That's just how VZW is on that..

Edit: Derp Lol.. Just seen you have the "F" model.. = Int'l

Input pixels normalization for image recognition app

Thank you for kind invitation! :)
It is important for neural network model, because pixels are input data for it. My custom network can do class predictions using inputs as numbers in range of (0..1). So, I need to divide every pixel in RGB format by 255 to get pixels value in range (0..1). Then pixels would be forwarded as input data to neural network for subsequent recognition.
Device isn't important.

Factory reset wiped SD card?

If there are no files on your card, where you actually even using it as supplemental storage before?
As for the DiskDigger app, if your query is whether it was supposed to write any restored files to your card depends on it actually being able to find any photos in the internal storage to begin with. If you went through any kind of restore steps and getting it back into a usable state, that greatly reduces the chance of getting your photos restored as a lot of them may or may not still even exist. Also, note DiskDigger is very, very limited in restoring deleted files on non-root devices so there's also that caveat. Read through its features listing in its Google Play Store page, they really should make this a much more featured warning but at least it is there.

Things don't bode well in recovering those photos. But be sure to implement some kind of backup solution so you don't lose anything from this point on. As @ocnbrze suggested, look into installing the Google Photos app, it includes an automatic backup & sync function so your entire photo library co-exists on your phone and in your online Google account.

If for whatever reason you don't want to have your photos to be auto-backed up into the Google's cloud, think about using Samsung's Smart Switch. Install it on a local computer and then you use it to manually back up your S7's data. Smart Switch will also allow you to a full backup so if the need arises it makes doing a restore much easier, and if you upgrade to another Samsung phone it makes migrating your data a lot less of a hassle.

Help with game development

This is also my first time using android forums so is it appropriate to ask questions concerning topics like this?
Welcome to Android Forums! :)

Yes, it's perfectly fine to post such questions.

One thing you might want to do, though, is use our handy-dandy Android Development board. There you'll find lots of people seeking and giving help specifically about development.

Take some time to explore the rest of the site, too, and feel free to jump in and participate wherever you're interested.

Getting word out

we do have a forum where you can post your apps here.
https://androidforums.com/forums/4/

Already done that: https://androidforums.com/apps/just-a-map.16435/

This one is nothing special (I made it mainly for myself), so I kinda get it, but with all the apps on that forum it seems like almost anything would get lost.

I'm looking more at marketing strategies and the like. I've got a couple that I can't see much if any competition, and there's a few games I'm working on that are actually new concepts. But even then, with so many others out there, how to you separate your app from the rest?

It almost seems like you have no chance unless you're one of the big publishers anymore.

What Android networking protocols/encryption actively in use?

Given you have doubts to the contextual info on the encryption schemes the WiFiAnalyzer (Open Source) app is showing, you might want to use other utilities to confirm or disprove your suspicions. Try installing the popular Wireshark utility on a computer connecting to the same local network as your mobile devices, it's free, with a very reputable, long history, and available for Linux, Mac, and Windows.
https://www.wireshark.org/
Install and configure Wireshark, and do a scan on your home LAN, making sure one or more of your mobile devices is awake, and preferably actively doing something that's online. Following these directions you should be able to at least get some corresponding data on the encryption scheme in use:
https://wiki.wireshark.org/HowToDecrypt802.11
You might also want to install the GlassWire app, it's a network monitor and firewall utility that you can also use to correspond with the information from the WiFiAnalyzer app and Wireshark scan results.

A last suggestion is to try to crack your own home WiFi network and see if it is or isn't as openly vulnerable as you think it is:
