SMS or MMS or mesages from another app such as whatsapp? if so, do you have stamina mode on?
Hi. I can confirm the problem. My wife and I both have Xperia E1. Sometimes we receive a notification when new SMS message arrives and sometimes we don't. We use default SMS application and have stamina mode turned off. This is a major concern, since the only way to know if someone has text me is to open SMS application in regular intervals and check if there is a new message.
I don't have problems with WhatsUp and Viber.
