I recently installed /e/OS R 0.18 on Samsung Galaxy Note 3 LTE (hlte) and I’m very pleased overall.
Mobile data connection is unreliable, however. I haven’t found this reported in the forums or in GitLab.
- Device model is SM-N9005
- /e/OS version is 0.18-r-20211003138753-dev-hlte
- SIM card works fine and is 4G
- Settings → About phone → SIM status says voice and data network type is 4G; home network, not roaming
- I’ve double checked APN settings and they are all exactly as recommended by the mobile operator
Turning mobile data off then on: often nothing happens; no H, H+ or 4G symbol; and browser reports no connection.
Changing preferred network type: the list has 34 permutations and combinations of LTE, NR, WCDMA, GSM, etc. I’ve tried about half of them. Sometimes changing the preferred type and waiting ~30 seconds enables H, H+ or 4G icon. Often it makes no difference.
Sometimes, tweaking the APN settings triggers something. For example, if I change the MMC port number then change it back, the mobile data connection could be enabled. Then it disappears after a while.
I’m getting the same behaviour both at home (mediocre signal) and at work (excellent signal, close to a 4G/5G mast).
When mobile data connection somehow is enabled, the speed is very good and there are no transfer errors (that I can observe). No problems making voice calls or sending or receiving SMS. No problems with wifi.
I bought the phone “as new, unopened” a couple weeks ago. I didn’t use the stock ROM long enough to try mobile data, and I don’t have a copy of the stock ROM to try and confirm the hardware is OK.
