2. select [sph];
3. changed:

•lvl 6 = 155 (was 136)
•lvl 5 = 140 (was 124)
•lvl 4 = 125 (was 112)
•lvl 3 = 110 (was 100)
•lvl 2 = 100 (was 88)
•lvl 1 = 86 (was 76)
•lvl 0 = 75 (was 64)
4. Repeat the same: select [sph2];
5. Back to Speech Enhancement > changed Common Parametre to Normal Mode;
6. Selected parametre 7, set to 96 (was 64);
7. selected parametre 6, set to 300 (was 400), supposedly adds a bit more bass to the audio;

I have noticed a significant volume boost during calls and it sounds more natural!"

29. How to put the apps on external SD card? (#2372)
R: For those who want to move the apps on the esternal SD card, follow these steps:
1. You have to install App2SD;
2. For App2SD to see the external SD card you have to checkfrom options din storage/default write disk/external storage; (if you willcheck built-in then app2sd will see just the internal si built in storage).

Attention, if you have installed apps in built in storage, after the check mentioned above, those apps will disappear.
The recommendation is to move all the apps from build in storage to external storage.

See posts 2304, 2306, 2308, 2290,2294 from the Softpedia forum.

30. Resolving the lost IMEI (#816)

R: In case you lost your IMEi after an installation, and you use a writing soft to have the IMEI again, you have a problem. You don't know the second IMEI. On the box is just the IMEi from the fisrt SIM.

The idea is this: Both IMEI numbers are the same, except the last digits.

So if the first IMEI it ends with 19 (for example), to find out the last 2 digits for the second IMEI you have toad 1 at the penultimate digit and subtract 2 to the last digit, resulting 27:

1. IMEI 1 = 19
2. 1+1=2 and  9-2=7 2+7=9 < 10
3. IMEI 2= 27

If the penultimate digit form IMEI 1 is 9, it results 9+1=0 but you will add 1 on the digit before penultimate digit:

Example:

1. IMEI 1 = 299
2.IMEI 2 =  307

ATTENTION
If the last 2 resulting digits for IMEI 2, add up, are greater or equal with 10, then the last digit from IMEI 2 will be less with 1.

Example 1:
1. IMEI 1 = 50
2. 5+1=6 and 0-2=8
3.  6+8=14 >10 so the last digit is 8-1=7
4. IMEI 2= 67

Example 2:
1. IMEI 1 = 38
2. 3+1=4 and 8-2 = 6
3. 4+6=10  =10  so last digit is 6-1=5
4. IMEI 2 = 45.
