I am on Miui and the default setting for the Preferred Network Type doesn't want to save. I want to change it but when ever I close it it won't save. Anyone knows how to fix it?

  • For 4G devices, default will be 4G. If you need 3G, just select it, device will save it, and switches to 3G. I don't know why it's not saving settings. Check whether you've applied right ALN4. – Rahul Gopi Sep 28 '19 at 1:52
  • What is ALN4? Also by default it keeps reverting back to LTE/TD-SCDMA/UMTS when I want to have it on LTE/CDMA/UMTS auto (PRL) which gives me much better coverage and will give me 4g more often for some reason. – Daniel Sep 28 '19 at 5:58
  • Sorry it was a typing mistake. I mean APN settings for that service provider. – Rahul Gopi Sep 28 '19 at 10:24
  • I have just reset it using a built in feature. I will see if that works. – Daniel Sep 28 '19 at 10:41
