Minor update addresses drop-call performance bug
In December of last year, we reported that there was an influx of complaints regarding the iPhone 12's poor call performance. Users flooded Reddit with reports that their calls kept dropping. Whether they were using 5G or LTE networks, they kept running into signal snags.
Affected iPhone owners said that they confronted their phone carriers, but the companies insisted that they are not the culprit behind with their drop-signal issues. Instead, the carriers pointed their fingers at Apple. "[Verizon] said that there is a major issue with iPhone 12 devices and it’s not just on Verizon, but other carriers as well," one Redditor said.
On Apple's Tech Support forum, there's 65 pages of heated discussion regarding the signal bug.
Apple is now addressing this call performance issue with the iOS 15.1.1 update, which only rolls out to iPhone 12 and 13 users. To download it, locate the Settings app, select General and tap on Software Update.
According to Forbes, the update is relatively small (385MB on an iPhone 13 Pro Max), so the installation shouldn't take too long.
