I have a new phone and want to use the old standard ringtones from my Samsung A3. Unfortunately, I do not know how to find it (not rooted phone).
I know that a similar question was asked here. Where is the default ringtone saved? but I can not access the folders described and the ringtone folder is empty (I have never used my own sounds)
The phone is huaweiY600 and Android 4.2.2 and I can not call or be called. After resetting to factory defaults, the SIM slot displays "Invalid IMEI".
Is there a way to access channel impulse response information on ios / android or any other mobile software? I've searched for features on the Android developer website that provide information about the signal strength of LTE signals. But I have to get the channel impulse response from a cellphone. Does anyone have an idea how to do that?
Each time the phone reboots, an app called SIM Toolkit will be displayed and added to the homescreen (in the upper-right corner of the bottom image).
How can you stop it?
Android 8.1, Sony Xperia XA1 plus, Microsoft Launcher
I recently bought a used Android phone. Is there a way to install malware, tracking software, etc. that is not on the SIM card but on some other type of memory?
