Does it show you have service when you have these issues? ... View more

I know what you mean, it use to pop up a list of words when you touched a word that was wrong but it doesn't have that anymore. That and speak to text has been really bad going from my note 9 to my note 20 ultra. ... View more

So it could be a few things doing this. One wifi calling being on could do this, ever since they did the wifi calling optimization bull **bleep** this has been a issue. If your wifi calling is on and your phone decided it was best to prefer cellular over wifi your calls and messages won't send or receive. But also I have noticed the inconsistent signal fluctuations on cellular and sometimes even the complete loss of service has started to become a issue. I have bought Samsung devices ever since I had the note 4 and I have had no problems but since I got my note 20 ultra 5g I have had problems with loss of service or signal fluctuation. I am getting frustrated with it now. Or when I have almost full 5g but every time I open chrome or YouTube it says no internet connection. And the auto switching wifi calling preference optimization bull has not been helpful on top of it. I have been frustrated with this device ever since I got it. It's been one thing after another. I have been having issues with wifi calling, signal fluctuations, no signal issues, screen mirroring through Samsung smart things ( Grey screen), touch screen inconsistencies, Bluetooth issues, charging port moisture issues, apps crashing, problems with the auto switching between 5g and 4g and good data signal until I go to use data than I completely loose signal. That among other things like voice to text **bleep** now, it can't understand what is being said and has a problem with punctuation being spelt out instead of adding the punctuation. Also has a problem with delayed text or no text displaying when using speak to text. Among other issues and I have tried countless options or settings to no avail. ... View more

I am also having this problem, but it started when I got my note 20 ultra 5g. I had no problems with wifi calling with my note 9. I went into my app settings and to wifi calling system app and turned off permission to change system settings and turned off permission to phone but it still keeps changing. so one of two things is going on, either the app is changing system settings without having permission or a different all is changing the settings. I will go into the phone and see what else I can find. Will let everyone know if I see something else. I did notice though that when clicking on wifi calling info it brings me to T-Mobile wifi calling option page so I'm thinking that the problem is leaning more towards the service provider and not Samsung (Device manufacturer)or Google (software provider). ...

There are a few reasons a screen can do this. The first is screen burn in, it's not really a burn in but if you leave your device on a certain screen for some time you can get that image permanently displayed on your screen. I suspect at least one of the users that posted pictures to have screen burn. The other is a software issue, if your able to fix it by doing certain things than it's going to be software related. The last reason I can think of at this time would be the screen is about to go out and it will need replaced. Especially if you have lines going horizontally or vertically across the screen.such as the green red or blue lines evenly spaced across your screen. You don't always need damage for the screen to go out, sometimes they just do. I would say it could also be due to the screens connection being loose as well ( unlikely but it could happen). ...

I have found that by turning off auto adjust feature on the samsung phones I have worked on it stops that problem from happening. Not sure if it's a temporary fix but all the customers I helped have yet to experience that problem again. ... View more
