Heat and humidity

I came back to cold weather the phone worked well again. In a few weeks I’ll be going back to the tropical heat

Hi and welcome to the forum.

First you may want to check the screen contacts are good, pressing the edges of the screen just below centre on the right can help.

Disassembling and reassembly may further help.

One further advantage of removing the screen is you can see the dampness indicators. This was my first concern on reading your post.

Warm tropical air usually has a high level of moisture, which will get into the phone and in time that can aid corrosion of the contacts and more. However of a more immediate concern is that taking a ‘humidified’ phone to a colder clime will result in moisture condensing in the phone. If you then go again to a warm climate not only will the phone absorb more moisture form the air, but the ‘water’ inside will evaporate and increase the total volatile internal moisture.

If you remove the screen there are test ‘squares’ to say if the moisture content has got significant enough that it voids the warranty.

So apart from pressure on the contacts or cleaning and avoiding ‘corrosion’ you may like to keep a drying agent near the phone. Silica gel come in little packets you can keep near the phone.

Whatever ensure there is always a good airflow around the phone especially when travelling from one clime to another.

There’s a video in the following that shows how to get the screen off.

Rain water inside - what could be wrong?

Hi and welcome. Further to what @OldRoutard has said it can take days to dry well in a flow of air and ensure you dismantle the phone to get air around the modules and help dry the contacts. For the dampness indicators you will have to dismantle the phone to the point where you remove the screen and then see this post and two above it. hopefully you don’t see a red square. The top left in the top image is the red square in the bottom one. [image]
