Android ignoring max length | WordPress.org

We have a issue with an android samsung phone (S22) – we need 3 characters max to be entered into a field (its the first part of a post code so it will be g1 or g44 for example) – this works fine. the text field id is #fieldname1 and its sent to a min length of 2 & a max of 3 – which works on ios/desktop/all devices I can check & test this on – but it ignores the max length on the clients Samsung android based phone

I have googled & there is a know android bug which ignores the max length and allows any amount of characters to be added.

I don’t have access to a device this happens on – but I have videos from the users showing the issue – I also cant replicate it on the Samsung developers lab either (i.e I was trying various Samsung phones to test this on) .

I have found various pieces of javascript which can force this – but I am not familar enough with javscript to know if what I have added is correct – & I also cant check…

Would this work? & can anyone check & test this?

$(document).ready(function() {
        $('#fieldname1').keypress(function() {
            if ($(this).val().length === $(this).attr('maxlength')) {
                return false;
