Exporting my key as a PEM file

Thanks, Brian, but no thanks. :)

I not only don't disable root, I set up all my computers to allow root log-ons. And I allow su - which I use frequently.

My passwords are strong, from the ground up, i.e., starting with my router.

Please don't think your suggestions are bad or anything like that. It's just that I've used *nix since 1985--with ZERO security problems, and off-site backups--and kind of know what I'm doing. :D

I haven't run a linux-based PC yet, but my servers (that I've been running for ~15 years) have root enabled - but direct login to root is limited by key, so only a handful of computers under my control can log in. It would pretty much require stealing one of them to get in. (that said, I won't claim to be a linux expert...)

Keeping Teamviewer active on phone

I'm using the TeamViewer Host. Do I need a particular version? Thanks for the advice!
It could be a matter where the app is going to sleep or your online connectivity is going to sleep.
Check that in your Settings menu that the TeamViewer app isn't being 'optimized' in the Battery settings. Also check on your Settings >> WiFi menu for any 'Keep Wi-Fi on during sleep' option is enabled and/or you might need to enable your device's Developer options menu and enable any kind of 'Cellular data always active' option. (this cellular option will vary depending on your phone model)

Help...

I dont know thats why I'm asking it's my music I created that I'm trying to download on to my phone
So what is this rights problem exactly? If you created it then how did you get it into Samsung Music and why won't it let you download it again (and what do you need to: surely you have your own copy)? Or do you mean something different and it won't let you upload? It's not completely clear what's going on.

Help How to free up internal memory on Galaxy J5

I'd be cautious about choosing such an app though. SD Maid is ok, though when using it you should think about which of its suggestions you actually want to clear: it's a powerful app, and you know what Spiderman's Uncle Ben said about great power...

But a lot of these "system cleaner" apps contain actively undesirable features: task killing/ram cleaning (different names for the same thing) which are not only not needed since about Android 2 but are often actively counter-productive. And of course some of these come from companies whose business model is to steal data from your phone and sell it to whoever will pay (Cheetah Mobile are thost infamous, but far from the only guilty parties).

New Friends Connect

I've an enquiry about your app:


What do I do if my new friend's phone doesn't have NFC in it?

Usually me and my friends(new and old) use Wechat, and that exchanges contact details via on-screen QR codes, and just about every smartphone has a camera in it. Perhaps QR codes could be added to your app?

FYI
I didn't implement QR scan at this moment, but the app now supports sharing via bluetooth. :)

Help Overheating if plugged into charger 24/7

Ok. Problem solved.

I bought a tp-link smart wi-fi plug as Ivt suggested and alternate it between two hours off and four hours on every 6 hours, just in case leaving the phone plugged into the charger 24-7 could potentially cause any damage.

Also, with regards to keeping the phone display switched on all the time, I downloaded an app that wakes the screen when I double-tap it, and since the harmony app is open when the phone auto-sleeps after 1 minute, when I unlock the phone by double-tapping the harmony app remains open. This way I could avoid the screen burn-in issue as MoodyBlues suggested and I can use the screen on full brightness and not worry about the phone overheating if I was to leave the screen on 24-7.

Thanks a lot of your help.

Couldn't have solved it without you.

Rendering graphics in android

Hi everyone. im relatively new to android specifically but i have 20 odd years in differnt programming languages.
For my third attempt i have tried to build an android version of a windows that is like google maps that stitches map tiles together and then rotates it if needed.
I creates a new class extends surfaceview and implements runnable to draw the map. if you just load and draw its laggy and adding rotate on the completed map just cripples the performance to being unusable.
If i then use google maps or other drawing apps like games, it is super smooth and renders fast.
Is there a trick i am missing with android that allows it to render or draw faster?
I have removed all the object creation from the draw loop. removed all the strings and just stripped it down to drawbitmaps and rotate with matrix.

Help I want to update my phone to Pie using SamFirm & Odin. How do I find the CSC/REGION???

An overriding issue with your model (SM-G965U) is with AT&T manually upgrading can be problematic. AT&T is apparently notorious for being resistant in releasing ROMs to consumers for their phones. Looking through other valid Samsung ROM repository sites, while there are typically a lot of ROMs for different carriers available, AT&T ROMs just aren't as prevalent. So unless you do get an OTA upgrade, being able to manually upgrade your device will be more of an issue.
Just some examples:
https://www.sammobile.com/samsung/firmware/SM-G965U/
https://updato.com/firmware-archive-select-model/?q=SM-G965U&exact=1&r=&v=&rpp=100

But I'm also a bit confused as you've stated this is an AT&T branded phone but you're going to use a Metro PCS SIM in it? Isn't Metro PCS now a MVNO tied to T-Mobile?

.... and just to add, yes it's easy to brick your device using Odin when you don't follow instructions and don't use the correct ROMs, which is basically true for any method or utility you use to flash your device. Just be sure to a) always have a safe backup solution and b) thoroughly research what you're going to do. Flashing your device just a whim is taking a gamble.
