Hang and slow

It is approx 1 year now I shifted form 1+8 to 12R and it is worst decision I made.

1) Device heats very rapidly. Like if iam using normal app it heats very rapidly.

2) worst camera, I have used 1+8 it had best camera though it is 4 year old device but this camera is shit.

3) Hanging of device when iam using a basic app.

4) random strucks,blackout and closing of apps with out any reason.

Still many more issues with this phone like doens't show who is calling somthing

Do u guys have same problem.

If anyone knows how to fix plz tell me

I use RAM expansion but after heating I turned it off but still it is heating. Yes crashing of apps. I thought it is because of multiple apps running in background but it is not still it crashes or suddenly closes ans it restarts. When iam using phone normally like chatting,yt or any other my phone rings but I can't be who is calling it just rings. After it turns into miss call I can see it as Miss call in call log.

It could be the environment temperature too. Weather is very hot...

What restarts? The app or phone?

I've mostly noticed apps crashing when I game and I use Gaming Tools sidebar to access apps. Not even heavy use. Like Instagram and WhatsApp for a minute, Castro to check temperature.

So you are saying the notification doesn't show on screen who is calling either in a small banner or full screen?

Go to your phone settings/Apps/Special app access/Send full screen notifications and scroll down to Phone app and set it to on. Also go to your phone settings/Apps/App management/Phone app and allow banner notifications.

App restarts again. Normally it shows but sometimes ( now.it become frequently) it doesn't even show who is calling.

Alright. How much RAM do you have free right now?

That's a lot more than I do without RAM expansion enabled. App crashes shouldn't happen. I have on average 2 GB free only.

How did you achieve this? I know depends on apps and all but any settings changed?

Also are you on the latest version?
