That wouldn't be too hard. I could find it

OK so according to my findings (and it could be wrong) here is the values

After digging around in telephony framework I saw all signal related info was stored in framework.jar ? surprising

but i think; GSM should be

- if (lteRsrp > -44) { // None or Unknown

+ if (lteRsrp > -20) { // None or Unknown

lteSignalStrength = 64;

lteRsrq = -21;

lteRssnr = -200;

- } else if (lteRsrp >= -89) { // Great

+ } else if (lteRsrp >= -97) { // Great

lteSignalStrength = 63;

lteRsrq = -3;

lteRssnr = 300;

- } else if (lteRsrp >= -97) { // Good

+ } else if (lteRsrp >= -105) { // Good

lteSignalStrength = 11;

lteRsrq = -7;

lteRssnr = 129;

- } else if (lteRsrp >= -103) { // Moderate

+ } else if (lteRsrp >= -113) { // Moderate

lteSignalStrength = 7;

lteRsrq = -12;

lteRssnr = 44;

- } else if (lteRsrp >= --109) { // Poor

+ } else if (lteRsrp >= -120) { // Poor

WCDMA

- if (lteRsrp > 0) { // None or Unknown

+ if (lteRsrp > -20) { // None or Unknown

lteSignalStrength = 64;

lteRssnr = -200;

- } else if (lteRsrp >= -91) { // Great

+ } else if (lteRsrp >= -97) { // Great

lteSignalStrength = 63;

lteRssnr = 300;

- } else if (lteRsrp >= -98) { // Good

lteSignalStrength = 11;

lteRssnr = 129;

lteSignalStrength = 7;

lteRssnr = 44;

LTE

Revert back to your old info because it was correct

[MENTION=6435663]hackslash[/MENTION] [MENTION=7354786]XePeleato[/MENTION] this is what I found. The other (none changed info I can't tell what it is) but the changed one on gsma and wcdma was wrong and still is in commit. But LTE was actually correct

Also if you don't want me to quote you feel free to say so. Might be too much :)

Also if someone wants to run around and checking for best signal strength on your network https://play.google.com/store/apps/details?id=de.android.telnet is a great app for you.
