Phone numbers looks bad and ugly. Currently, the phone numbers are just unformated strings of numbers, for example 555555555555.

Describe the solution you'd like
title
They should instead look like (555) 555-5555-555, +1-212-555-0101, 555 555 5555 555 or +491631737743 etc.
Its going to vary from country to country. That should be the default and then you could change it in settings to another format.

Conditions

1. If 1 number appear 3 times in a row group it
2. If 1 number appear 2 times in a row group it
3. But when grouping 2 numbers like in condition 2 if a lone no. if on it's left or right take it into the group
4. There should be min 3 groups and max 4

@Rexadev may you show some examples? I dont get it tbh, I mean mainly 2 and 3

[Netpilgrim]

Because there are many different national standards and personal preferences with regard to grouping, I strongly suggest that the default should always be the string as entered or imported.
The only sensible format for any kind of normalization would be the international ITU format without any grouping, e.g. +491631737743 (also the safest choice for copy-and-pasting).

@Netpilgrim cant it be done based on language maybe? and then on preference?

Hi,

Me and @Aychoumane are computer science students at the Paris 8 University.

In the context of free-software development class, we have to contribute to a project of our choice, so we would like to work on this issue.

We were thinking of using the android.PhoneNumberUtils library, would it be ok ?

Thanks.

@theoUniv its android.telephony.PhoneNumberUtils, right? If yes this project already uses it, so if end result is good then I dont see any problem :)

While trying to push our branch on the git, to make a merge request. We got this error.

Any requirement to contribute by coding ?

@theoUniv When working on open-source projects, you have to work on your own fork and after finishing work, create PR for merging the fork with upstream. Read how it works, e.g. here: https://www.freecodecamp.org/news/how-to-fork-a-github-repository/.
