Have you tried restarting the phone? Do you have a screen-protector on it?

 

I just recently &ot the same device.

I have used ZTE devices for years, and for the most part have found them to be great for the price.

But not the Quest 5.

Mine, right out of the box, has zero screen response near the edges on both sides.
This makes it basically impossible to type a message or to tap anything along the sides or corners.

I truely hate the device.

If I thought for a moment that I could send it back I would have done so immediatelly.

I have never been so disappointed in a smartphone before.

Honestly, the free phone provided by cellular companies have been twice the device.

I am sorry that we have to share such an experience.

Currenntly, I use the phone only to look up oil capacities of cars and trucks at my work.

I have a great browser, that I changed the homepage to a website with the info that I need.

So, the screen being junk has no effect in this use.

If you can send it back, do so, and get something better.
To be honest, that is not asking much.

I would have sent mine back immediately, but I am weary of dealing with the miserable cellular company that I got the thing from.

What is so sad is that the cellular company was great, and provided great phones and service right up until Sprint mearged with T-Mobile.

Now the service is nonexistant, there is no customer service available, e-mails go unanswered, and the devices are even garbage.

Looks like a terrible device....

 

well i would factory reset the device to see if this is a software issue. if it still persists then we can safely assume that this is a hardware issue. if it is a hardware issue, then hopefully it is still under warranty and you can return or replace the device.
