I have the exact same model (Colour and storage)
I too used similar deal. Apptronix gave me 24k for my 3yr old iPhone X + 6k HDFC CC cashback. My wife used same deal to sell her iPhone X as well to get 12 Mini 64 GB Green and loves it. The 12 mini is ridiculously light and is not bad screenwise as I had some reservations about it. But wife was adamant and glad that my fears were unfounded. Rare case of (Wife is always right?)
I am an iPhone veteran. I have used every alternate iPhone model since original iPhone 2007. Here are the few things you must have in settings
- Disable autocorrect in settings
- Enable Night Shift schedule
- Enable Do not Disturb schedule
- Settings -> Contacts -> Sort Order -> First, Last
- Disable iCloud backup if you are not getting extra storage. It will get stuck due to original 5GB free storage limit as backups get bigger over time.
- Download Adguard content blocker from App Store. Then go to Settings -> Safari -> Content Blockers and enable all Adguard related settings. Then Open Adguard app and just choose Adguard Base filter and Peter Lowe’s Blocklist. Just the two. Maybe use Privacy filter too. Then enjoy adfree Safari browsing.
