My phone is restarting automatically and very frequently. Sometimes it also stops opening wifi. It is also not showing network and lags so much.
You should ask for replacement as soon as possible if the place where you at is not at lockdown. This thing can take time so I would suggest you to get in touch with them via twitter. A new phone shouldn't be behaving like this.
It'll likely be a common hardware issue, I'd get it replaced asap (preferably with a different model). This phone needed a lot more time in the oven, not that Asus will admit it.
All the best, bud.
