I have been using this A70 for 1 year, facing same issue of Low singnal strength after updation. Another problems are battery draining very fastly, vibration mode not working. i changed sims (Airtel, Jio and Vodafone) in both slots , changed network settings- selected network as automatically. but the result is same (signal strenght very poor). Im totaly upset for using this phone, Im not recommend to any one for Galaxy A70 or any other samsung phones (My friend using M21- He faces the same issue for low signal)I wil not buy samsung brand if i buy a new phone .
read . he has mentioned about all three network provider. you want him to change to which sim???
I don't know how you people talk without knowing the fact. it s fact that samsung has low signal reception. You will not notice it when you are blinded by samsung brand.
