I'm using samsung a55, but it had a big issue of signal it's signals are very weak as compared to other mobiles and sometimes when other mobile have 2 or 3 signal then it shows emergency in same area.
I was using A70 older version 2 years ago.when I opened it from back i found that signal antennas are sticked on its back cover.whenever we open it from back and then stick it again some antennas tear off.
Have you used a mobile cover? Sometimes, mobile covers create this type of issue. If the issue is still there after removing the cover, then contact a Samsung service center.
Before buying any mobile device, please check the reviews of the mobile. Never believe in paid promotion marketing; only rely on real user experiences.
