Jelly
Jelly 2
Do not confuse with Jelly Star (below).
Advantages
It’s really small.
Android 11.
Even if you tell people, they might not consider it as a normal smartphone and will except it easier as a exception when phones are normally not allowed.
Disadvantages
Recommended only for experienced loopers (some settings are not recognizable, you have to know from experience with a big Android AAPS phone, how and where what is located. Some AAPS buttons are hard to touch with a lot of feeling, but not with stubby fingers.)
Can only be used as LooperPhone. It’s better to have a normal smartphone in your pocket.
Battery life optimization
The Jelly 2 comes with strong optimization features that must be disabled for AAPS (and other DIY apps like BYODA, xDrip+, OOP2, Juggluco, etc…).

You can leave Intelligent assistance enabled, but it must be disabled for DIY apps.

You can enable NFC for Libre sensors.

Jelly Star Mini
Features
Android 13
8 GB RAM
Battery life optimization
To avoid interference with AAPS, the Jelly Star ‘battery usage’ should be disabled by selecting ‘unrestricted’ (and other DIY apps like BYODA, xDrip+, OOP2, Juggluco, etc…).

Intelligent Assistance and App Blocker
Like with the Jelly 2 (above), the Jelly Star should have ‘Intelligent Assistance’ disabled for DIY apps. Similarly, ‘App Blocker’ under ‘Settings’ must also be switched off to avoid disruption with AAPS:

Google Play Protect
Remember to disable Google Play Protect.
Remote Connection for Weak apk
For certain smart watches, like the Samsung Galaxy, ‘Remote Connection’ under Samsung Galaxy’s Advanced Features must be switched on to use the Jelly 2, Wear.apk & AAPS remotely via wifi.
