Depending on your Android version, the signal will show one of these sets of indicators:
- LTE, H+, H, E
- 4G, 3G+, 3G, 2G
They mean the same, so nothing wrong here.

It is not about the bars shown in the icon in upper right corner. It's about dBms. For example for my country dmms should vary between - 60 to - 110 where - 60 means very strong signal and - 110 very poor signal. I terestingly, thos value may differ between the bars in the icon you are referring to. I do not want go more into details here.
To check your real signal strenght based on dBms go to Settings - - > information about the phone - - > Information about the phone - - > sim card.
See the screenshot below for reference. I will only tell you you are not the one suffering from poor signal. This device has poor antennas:
Hope this will help.

Hello, same problem for a few days, loss of signal to call, I have 4g and a very good speed but I can very rarely make a call, the same for the reception of call. I do not have a problem with mobile data, just to go and have the call. 1 bar only, on the 2 sim.
I try a software repair but nothing helps.
no new application, it's the same thing after a restore.
