I think you have been miscommunicated, my present m20 has a tampered display. I checked the rates online for the display from Samsung store / spare parts. The rates were close to similar with Samsung service center.
I think it will be a great buy, just try to get it in some offers. Like I bought my M30 on exchange, so the effective price was around 7200. Plus I got a cashback of 1K on Amazon, plus acko's one time free screen replacement for 1 year. So overall it was a great purchase for me.
I know it's not the best, that's why I suggested to try to get in some offer, if thinking about buying it. The overall specifications are above average considering the price. But I think it's better than any other device based on Samsung's brand name. If you have any plans of exploring Chinese brands, I will suggest you Realme.
please don't buy seriously phone lags alot camera is oky in outside daylight but struggle alot indoor moreover their is edge distortion problem in photos clicked by it you can play pubg in it but the phone heats while playing near right top area and u can literally feel the device is getting hot overall the performance is laggy have been using this for 3 months i wasted my money on this crappy device if you want to waste yours then buy it moreover no secure folder,no applock ,no Samsung pay in this device
