NFC stops working after writing on iCODE tags, Android 6.0

I'm developing an android application to read and and write different NFC tags. I've encountered a problem with a specific tag ,iCODE SLI X and iCODE SLI S. After i write information on the tag, i'm not able to do any other action, looks like NFC stops working correctly because if i restart it, it will actually read the tag. This does not happen if i use another tag type like MIFARE Classic 1K. Android version is 6.0.

On the other hand, if i try the application on another device with Android 6.1 or 7.0 (exact same code), iCODE SLI X and iCODE SLIS will work okay, but not MIFARE Classic 1K.

Besides trying different samples of codes, i have also tried 2 applications on these devices. On "NFC Tools" you can see exactly the same problems that i have on my application. "TagWriter" from NXP is the only application that works like a charm with all types of tags.

Here is the code I'm using to write the information on the tag:

@Override
protected void onNewIntent(Intent intent) {

    if (mNfcAdapter.ACTION_TAG_DISCOVERED.equals(intent.getAction())) {
        Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
        if (tag != null) {
            try {
                Ndef ndef = Ndef.get(tag);

                NdefRecord text1 = new NdefRecord(NdefRecord.TNF_WELL_KNOWN,
                        youstring1.getBytes(Charset.forName("US-ASCII")),
                        null,
                        youstring1.getBytes());

                NdefRecord text2 = new NdefRecord(NdefRecord.TNF_WELL_KNOWN,
                        youstring2.getBytes(Charset.forName("US-ASCII")),
                        null,
                        youstring2.getBytes());

                NdefRecord[] records = {text1, text2};

                NdefMessage message = new NdefMessage(records);


                if (ndef != null) {
                    NdefMessage ndefMesg = ndef.getCachedNdefMessage();
                    if (ndefMesg != null) {
                        ndef.connect();
                        ndef.writeNdefMessage(message);
                        ndef.close();
                    }
                } else {
                    NdefFormatable ndefFormatable = NdefFormatable.get(tag);
                    if (ndefFormatable != null) {
                        // initialize tag with new NDEF message
                        try {
                            ndefFormatable.connect();
                            ndefFormatable.format(message);
                            ndefFormatable.close();
                        } finally {
                            try {
                                //ndefFormatable.close();
                            } catch (Exception e) {
                            }
                        }
                    }
                }
            }catch (FormatException |IOException ue){}
        }
    }
}

I can't understand what I'm possibly doing wrong ...
