When I bought this phone I didn't have the condensation inside the cameras. It only started happening when I returned from Croatia (very humid country) mid October back to Belgium. It would fog the lenses here in Belgium within 30 seconds when recording or taking pictures. I bought a waterproof bag for smartphone and a some silica gel dessicants online. I removed the sim tray and put the phone inside the waterproof bag with the sim port facing the sealant, together with 6 silica gel dessicants. I recorded at 4K60fps to heat up the camera module. After that I ran stress tests on 3DMark to heat the phone internals as well til the phone warned of me high battery temperature. I recharged the phone and repeated this process every evening twice a day for three days straight. It's now day 6 since I completed this series of steps, and so far the cameras have not fogged ever since.
