The sensor on the phone does not respond, what should I do? Samsung Galaxy S3 screen does not respond to touch
If the Galaxy S3 fell on something soft or wet - for example snow, then there will be one solution, if the fall occurred on something hard - floor, tile and there is no visible damage on the screen - then another.
The smartphone turns on and works, receives calls but cannot answer because the screen does not show anything. In this case, the phone was luckier than in the option in which the device turns on before the logo, but only the sound is invisible, and no call signals are received.
In a simple case, the display connection cable simply gets wet or comes off due to temperature changes, without mechanical damage.
We disassemble the smartphone into parts. We take out the battery sim card sd card. We dry the phone disassembled, but do not heat it with a hairdryer, and at room temperature in a dry place, let it be a little warmer than usual, and so on for 3 days of natural drying. We assemble it, try to turn it on, if the screen shows but does not load it further, then the problem is a failure operating system and you need to restart the device.
We go into the “Recovery” mode, one by one launch the “Home” button, “Wipe Cash”, then “Wipe data/factory reset” and then “Yes” - “delete all user data” and at the end: “Reboot system now”. The phone will reboot, all information will be cleared from it and it should turn on as after purchase.
If it didn't help. Let's disassemble the phone further, instructions on how to disassemble Samsung Galaxy S3 can be found. We disconnect all the spare parts and remember how they were connected. We dry them for one day, after drying we look at where oxidation could appear, more often if the screen suffers, then the connecting cable oxidizes. We clean it and other boards with a dry brush very carefully and carefully, with love.
We assemble and turn on. If it loads before the logo, then we reboot the smartphone again as described above.
If the phone still doesn't turn on. We take it apart again, and put it back together in the same way and turn it on again. If despair sets in, you should take it in for repairs. The diagnosis will be as follows - replacing the display unit will cost from 7,000 to 9,000 rubles, depending on the standard of living of the cities.
But you shouldn’t refuse to solve the problem on your own. More often, the Galaxy S3 simply goes into emergency - protective mode so that the display does not burn out and normal drying and further Reboot will save it without “replacement”. Helped people: 13645 once.
