I have a OnePlus 3 and have made every effort to check that all my notifications for calendar, whatsapp, emailing, etc. are set to both vibrate and make a sound, disabled all battery optimization features for apps as outlined here http
/www.tomsguide.com/faq/id-3026187/disable-doze-android-marshmallow.html, tried using screenlock wake apps to avoid having the CPU sleep, and more. However, I am still unable to get notifications for whatsapp, emails, calendar reminders and events once my screen goes to sleep or I lock then phone and it's idle (so after about 15-30 minutes of it sleeping), but calls and texts seem to come through fine (or at least I haven't noticed these being an issue as much). This is a HUGE inconvenience, as my main reason to have a smartphone is so I can check emails, calendar events and such right as I receive them, and not only when I wake up my screen (which then bombards me with all my previous missed notifications from hours before). I have a feeling this is an android 6.0 issue and not due to the OnePlus 3, because it's been reported in other sites and by people with phones also using either this OS or lollipop. My older Samsung galaxy S4 running kitkat never had these problems, and at this point I'm very keen on going back if I can't get my new phone (or this OS, as I predict) to notify me right away even when my screen is locked and phone asleep (I can't always remember to check it especially if I'm busy at work). I am willing to root the phone and change settings if that's an option, but I would please like to see if you guys have any other suggestions for allowing my phone to receive notifications right away even when in sleep mode/idle/dozing. Thank you for your time in advance
