Samsung Galaxy S5 Screen Fails to Illuminate Outdoors: Unlock Button, Low Temperatures, New Battery

I have a problem with the Samsung Galaxy S5 phone, it happens that by clicking the unlock button or the start button the screen does not want to fire, there are only millisecond flashes. It usually happens when I go outside, where the temperature is a bit, or even much lower. For example, I had such a situation yesterday, for 2 hours outside I did not want to start the screen, while a moment after coming home it worked as if nothing had happened. I thought it was the fault of the battery, so I bought a new one, but the problem persists, so that's probably not it. Removing the battery and firing the phone again will do nothing if the problem occurs. Has anyone had a similar event, or has any idea what's going on, even if it didn't occur on the same phone model? Every opinion is important to me.

The phone has been repaired or it may have fallen?

Disassemble the phone and check if it is damaged or if there are any signs of moisture.

Hey. In galaxy S5, the lcd tape often comes out. When it goes out, press it lightly (right side from above) - it should surprise. If it did work, it must be removed, slip the tape correctly and glued back. It will work

Alternatively, the flex tape, which is welded by the hot bar, could have peeled off ... but start from scratch first. Check connections, correct connection, etc.

The tape is attached to the push-in connector and not to the connector.

It looks like an already opened phone and poorly glued.

I have a new phone call, it has never been taken down. He fell in his career several times, but his behavior happened not after the fall, but suddenly.

How should I check it?

You take your phone apart and check if the tape is securely attached or damaged. You also check if the board itself is not bent, there are no mechanical damages.
In your place, however, I would give the phone to the service, because you can do more damage yourself.

At S5, sir, do not go without experience.

It is easy to damage a very expensive display.

Just as luk90 writes, it's better not to move without experience.
How do you press the glass bends, is it stiff?
By the way, I had the S5 quite recently which came to me quickly - according to the customer, I never undressed, bought in the salon. It turned out that fast was already made, and in addition at LOCA.

Fast is stiff. After firmly pressing the upper right corner, the problem disappears.

Either the tape is sticking or the problem with the contacts in the display connection with the motherboard, anyway you have to disassemble. As you have never done before, entrust it to a specialist

As I mentioned, raise the fullset, remove the old glue and reconnect well

As far as I know what to do, thank you all for pointing me to the cause.
