I have a few apps which generate relevant notifications - SMS (Messaging; not the stock app) - Whatsapp - Telegram - Email (Maildroid) - FR24 Currently I have these configured to do one beep and blink the LED. For the messaging apps I could not find any way to get anything showing on the lock screen, short of the text itself showing also (which I don't want for obvious privacy reasons). So I disabled all lock screen notifications. I am not sure if this is even possible. I would like e.g. an email icon (icon only) to appear on the lock screen if there is an email to look at. But I don't want pop-ups when the phone is unlocked. I find them a PITA because you have to wait for a while for the popup to go away before you can continue doing anything near the top of the screen.
