Nothing 3a Intermittent connectivity issues

I'm surprised nobody asked this here since nothing 3a forums are flooded with requests about this.

Myself I'm facing this issue on my nothing 3a.

Data sometimes drop for like 10-15 seconds with the 4G/5G letter vanishing, at times showing an exclamation mark indicating no network, and then reconnecting itself again after.

The wifi happens as well but with slightly less frequency. It is botherline driving me crazy (not that I play much real time games) especially when attempting to reply a message urgently.

In a way the most basic function of phone which is connectivity is not functioning as expected

Methods to resolve given in forums such as resetting network options, airplane mode toggling, restarting phone, clearing cache have all been tried and issue persists. Anyone has a fix or facing the same issues with any resolution? My device is under warranty till May
