I have now jad 2 LCD's and a digitizer break on my 2 month old phone. Never had an issue with a Samsung phone in the past but despite having a case and a screen protector my phone seems extremely flimsy. the second LCS, OEM part amd replaced by an approved dealer, broke when I was trying to fix a bubble im the protector. My model is an A70, I have 2 friends woth an A50 that have had the same issue. I will not recommend these phones to anyone, better off getting a pixel 3XL for the proce I paid. signed, formerly happy 12 year Samsung user.
I had the A50 now have the A70 i don't know what your problem is with these phones but I'm super happy with both of these phones. The Pixel 3xl I had as well just to try it out the only plus was the updates everything else on that phone was garbage. Starting from screen,battery life and that lovely notch.
consider the a70 is a mid ranger you cant compare it to a 3xl. No problems with my A70 and I dropped mine a few times with a clear case and no screen protector. If you bought your A70 outright your kinda screwed without warranty considering the repairs cost more then the phone.
