Samsung prove that the earth all ways circle

My samsung a 72  all ways rounding while oppen you tube  now i am determined to change this device,in the case of network reception chineese phone more better than samsung

I visited  sevice center of oppo,vivo,mi, realmi and samsung all of these expect samsung, one or two customers but samsung service center a huge people  for service their device so i can understand chinees better than samsung

Any samsung a 72 users faced heat problem while using apps like you tube moj etc

Very poor to net work reception  very poor device my former device too much better than this
