Hello Support,
Today I got the new Sim card for my xa.
So I put it in the phone and I notice that the signal is poor. Directly compared with the xperia l from my girlfriend (same provider of COURSE) the signal is not halve so good. More than 4 dB! Signal strength difference! In the house the signal is so weak, that I even can't do a call, where the xperia l is at full range! If I move a little bit, the signal grows! I'm talking about less then have a meter! GSM settings are correct! Any suggestions, or need I bring it to service?
Greetings
Are you testing both by doing this?
Settings > about phone > status > signal strength
could you post the numbers on both phones here
also which model number do you have?
settings > about phone > model number
and which carrier/network do you have and which country?
you forgot to include the other info, also, there isn't much difference in signal strength, don't get fool by the signal bars at the notification bar, what you should care about is the signal strength (dbm asu)
| -67 dBm | Minimum signal strength for applications that require very reliable, timely packet delivery. |
| -70 dBm | Minimum signal strength for reliable packet delivery. |
| -80 dBm | Minimum signal strength for basic connectivity. Packet delivery may be unreliable. |
You have bad network coverage with both devices, that's a network issue not a phone issue.
I'm having the same issue with my XA Ultra after some travel this week. It would bounce between 3 - 4 bars of LTE, dip to HSPA+, and drop signal altogether. This is also happening since i've returned, not sure what is causing it. My other phone works perfectly.
FYI this is a wider spread issue - it seems folks with ATT maybe impacted (as with myself). There is a thread on XDA:
