It's possible or not possible 🙂
Which charging animation do you want?
I have no animation
Hi, are you saying you're not getting the rapidly charging words and lightning bolt when you plug-in the charging cable? Are you using the cable and charger that came with the phone (when new)?
There is no option for OnePlus 7 I think but u can put screen saver like photos, clock and colours
You'll have to install 3rd party application
Your screen must be locked to see the warp charge animations when you plug - in the charger.
