[General Questions and Answers] DiamondJohn:
I have a Pixel 4a 4G as my daily, running A11. I found and purchased a cheap used one to use it to test an upgrade to A13, as I have a few deal-breaker apps / config that are getting old and may or may not work on A13; and since TWRP for this device is not really working, a Nandroid backup-restore on failure, is not an option.

I have tested a few apps/widgets so far, and they work (some aren't even on the playstore anymore). One of the apps I use is a custom launcher. This app is NOT available to install on A13. I can copy the APK from my daily and it installs on the A134 device, however, it is a paid app that has some tricky validity check with your playstore account (that you have purchased it) before it unlocks the premium features; which is what I need to check.

In the past, I have had no issues upgrading devices, logging in to my main account, and having the premium features auto-enable.

Now, to check the premium features on my A13 device, my plan is to turn off the A11 phone, log into my main PlayStore account on A13. And hopefully, that will enable the premium features. The possible failure points of this plan are:

1. The fact it is not enabled for download & install for A13, the Registration/Purchase check will fail for the A13 device also

2. What worries me more, is that the switch to A13 device, by first turning the A11 device off, and then relogging on with the other A13 device to my daily account, the playstore purchase check will see it as an attempt to scam the purchase by installing to two device, and lock out my A11 daily when I switch back. First powering down the A13 device before restarting the A11 device; ie one device at any one time logged in to my main account.

Am I being overly concerned or does the playstore handle that sort of tap-dance ok? I know in the past I have upgraded & downgraded devices when trying out new ROMs, but that was always on the same device. This launcher is a show-stopper to me.

PS: "Lightening Launcher", allows you to resize, rotate, skew, 0-100% transparency widgets that do not have any of those features built in. And you can add code so click and long-click can do different things and change icons to random images, have folders in folders with widgets in folders, [n] folders deep etc etc etc the list is only limited by your imagination and your commitment to spend the time to set it up. Since I have been using the launcher since Gingerbread, I have slowly developed/built my home screen to "Just how I like it" and use my phone; many years of commitment to this feature packed launcher. But it hasn't had an update for a few years, so I think its abandoned, and hence not ready or knows of A13. I have never seen any other launcher that even comes close. But I stopped looking a few years back, so is there any new kid on the block? And no, I am not asking for "your fav launcher", its the features listed above (and more) I want, and last time I checked, "Nova" and ilk just do not cut it[/COLOR]

WHOOPS! My bad, there is a setting (that when I restore from a backup gets set automatically, for the past 5 years) where you can switch between "Standard Mode" and "EXPERT mode", which enables the (what I thought) were the paid-for/premium features, when in reality were simply turned on in the settings. :oops::whistle: and to add further insult (to me), its the very first setting!! Normally I dont go into settings, as I have been stable in the way I have it set up. Well thats my excuse....

And I did a further search for an alternative, and since its no longer updated, the dev has done the very honorable thing and open-sourced the code onto github! :love:
