Developer Tools

Hi Roy! Is it OK to say that I love you? Here is the deal: Samsung A5 2015(2016) mobile non-upgradable to the 7.1 version of android. Lots of space in the SD card but no "Developer Tools" possibility in my Settings. Internal memory constantly hitting the 96%-97% because I was crazy enough to set WhatsApp to back up 5 days rolling. Other "move to SD" apps installed before, but they would not touch Apps built as "non-movable" - such as WA. And there you come with this jewel. It will still not touch the useless core apps (for me) such as Samsung Health, Samsung Pay and Word, but it does a hack of a job on all the others we have downloaded ourselves and which developers had not been so kind to set as movable to SD. So all that "beginners" as myself need to know, is that they should tap Developer Options once the Developer Tools App is open, scroll all way down to "Force allow apps on external" and then they go to their Apps management windows in Settings, pick app, storage and see which has the change button available. And move them to SD. WA tested and works perfectly. So now just going down my list. Thank you. <3 this has been a hard one to crack for a while.

Not sure why, but got forced an update to 2.1.0 on androidTV v8 (api26) and ofcourse now it is incompatible and nolonger opens? Any chance for dev to put previous gen version up as a separate app? /// edit: v2.0.9 (os9 api28) apk that i found seems to open fine on this os8 api26 tv... oh and why os reports the 4K display as 1920x1080 ? YT & NF seems to get it is actually 4K screen, why not any sysinfo apps? (4K screen is also reported correctly when connected to Windows PC with Nvidia drivers)

LOTS OF TOOLS to use, but puzzling to me. I'm EXTREMELY INVESTED and eager to understand the process after becoming an android developer Eg. What devices can be used, what apps to download and what not to download, I'm Trying to learn Android developer tools on my phone ,NOKIA C30 1. what's the best device to use if I don't have a laptop?(can I use my android phone or my androidtv?) 2. What's a cheap yet powerful android box for 2022 to develop on? Can I flash a new OS on my phone just using tv?
