I learnt this today. Hope it helps others learn a little more about using their iPhones.
On the desktop I can easily create the Omega symbol by simultaneously selecting option + z, but this is not possible on the iPhone. So here is what I learnt.
to include the Ω symbol as a keyboard choice do the following:
1. go to your iPhone settings/general/keyboard/text replacement
2. Tap the + sign at the top right corner
3. Copy the Omega Symbol Ω
4. Go back to text replacement settings and paste the copied symbol in the “phrase” field
5. Then type omega (or ohm) in the “shortcut” field
6. Now the Ω symbol will be offered as a choice for selection in the text whenever you type omega - I use ohm rather than omega just to keep it a fraction quicker.
Hope this helps someone.
Not sure if it is also an applicable shortcut for Android systems.
