Nokia India — nokia 5.1 plus

Purchased a nokia 5.1 plus around a year ago. It has been giving me software problems ever since. It randomly restarts without my prompting it to. It has become so much of a problem that i've had to purchase and use a different phone. I've been in contact with nokia service executives multiple times over the past few months and they have not been very helpful. This is very annoying and from my knowledge a lot of people face such problem with nokia product software issues.
