Coming from Stock Oreo on the Mi A1 I have noticed several networking bugs.
1. There are custom roms out there, I've yet to figure out which ones, but several are messing with the persist partition, and changing the WiFi Mac address, at least this is my understanding, as it relates to the persist partition, and I have had my WiFi Mac address changed, when flashing some custom roms.
2. In regards to the Mobile data icons in the status bar on the last 4 roms I flashed, FireHound, LOS 15.1, AospExtended 5.6, DotOS, all had this problem, but for some reason DotOS didn't fluctuate nearly as bad as the other 3 roms...
3. In Stock Nougat & Oreo, if the phone stays in one area, the bars don't move, if they do, they rarely move. On these custom roms, the bars are constantly fluctuating up and down literally within 3-5 seconds, I'm not joking. As example, In 3 seconds it is half full, 3-5 seconds later it's empty, another 3-5 seconds a quarter full, and it just keeps cycling around, of course not in the same order, but it constantly changes every few seconds.
4. Network & Internet > Data Usage - In the Stock Roms, when using Dual Sim cards, you can turn both 'mobile data' on, with these custom roms, it has been only allowing one to be turned on at a time.
5. Network & Internet > SIM Cards - The names appear different in the custom roms, instead of SIM 1 & SIM 2 they read Card 1 & Card 2. Next when you tap a sim, the popup, under SIM name nothing appears, and the Carrier shows Unknow.
6. When getting a voice mail, the notification will say; Voicemail - Sim Card, slot:0 - Never seen any slot:0 or any numbers appear like this in the Stock Roms.
