I bough A71 in May 2020, its "on screen" proximity sensor was working fine. But after few days it started behaving abnormaly. Screen doesn't turn on after I put away phone from ear. And screen also keeps turning on during call.
Furthermore I noticed that sensor's blinking has faded. It would blink bright before but now it is faint.
It seems this is the problem with A71 proximity sensor out of the box. I was having same problem, I factory reset it thrice, after that it is working fine.
I am also facing the same issue. Day before yesterday I done reset settings. After that it is working fine till now. But I dont know whether it is a temporary or permanent fix.
At this time all the companies increased their products price. But the samsung is the only company decreasing their price . Here you clearly understand how much demand samsung is having at this time .Reason behind this they selling their mobiles with WORST EXYNOS PROCESSORS in india. If you play big games they will hang like any thing . Their service is also WORST.
DEAR FRIENDS,
I HAVE PURCHASED SAMSUNG M30S MOBILE.
THIS MOBILE SIGNAL RECEPTION IS VERY WEEK. CONFIRMLY I WILL BET SAMSUNG TECHNICAL PEOPLE ALSO WITH 100000/_ REGARDING SIGNAL RECEPTION IS WEAKER THAN OTHER MOBILES LIKE XIAOMI, REALME LIKE CHINESE MOBILES. DONT PURCHASE THIS MOBILES . THEY ARE PROVIDING THEIR ' EXYNOS ' WORST PERFORMING PROCESSORS. THIS IS REAL WHAT I AM TELLING . BELOW I HAVE GIVEN SIMPLE EXAMPLE FOR YOU.
FOR SAMSUNG S20 MOBILE , THEY ARE PROVIDING THEIR WORST 'EXYNOS' PROCESSORS IN INDIA , FOR THE SAME MOBILE IN AMERICA THEY ARE PROVIDING BEST SNAPDRAGON 865 PROCEESOR . EVEN THEIR KOREAN PEOPLE ALSO HATED THE SAMSUNG 'EXYNOS' PROCESSOR PERFORMANCE IN ' SAMSUNG S20 ' MOBILE.
AND THEIR SERVICE ALSO VERY WORST. TODAY I VISITED THEIR SERVICE CENTRE TO RECTIFY THE CHARGING PORT PROBLEM , HE TOLD THAT IT WILL TAKE ONE WEEK TO 10 DAYS TO RECTIFY THE PROBLEM . THIS IS A SMALL PROBLEM . I TOLD HIM TAKE THE COMPLAINT , AND GIVE MY MOBILE BACK , AFTER ONE WEEK I WILL COME AND I WILL GIVE THE MOBILE AND RECTIFY THE MOBILE WITH NEW PART . HE REFUSED FOR THE SAME . REGARDING THIS ALSO I CALLED THEIR CUSTOMER CARE , THEY ARE NOT ABLE TO TELL WHERE THE PART AVAILABLE TO THE NEAREST SERVICE CENTRE IN GUNTUR DISTRICT.
OTHER COMPANIES ARE DOING SMALL PROBLEMS WITH IN ONE DAY. BUT SAMSUNG IS TAKING 10 DAYS . THIS MUCH OF WORST THEY ARE DOING SERVICE.
THEY ARE RELEASING NUMBER OF MODELS WITH SAME PROCESSOR 'EXYNOS 9611' BUT NOT MAINTAINING PROPER SPARE PARTS AT THEIR SERVICE CENTERS . THEIR SERVICE CENTER PEOPLE ARE BEHAVING LIKE GAZITTED OFFICERS. FIRST OF ALL THIS IS THE MAIN PROBLEM WITH SAMSUNG.
Tap & Hold on the "Phone" app then go to App info>Storage> then perform "Clear cache" and "Clear data" and then try again.
Even if it doesn't work then perform a factory reset on your device. Even not, then take your device for servicing to Samsung authorised service centre.
