Learn How to Remove the Call Log Limit on Your Sony Xperia Device
If you’re one of those people who makes just an inordinately large number of phone calls (and kudos to you for using a phone for its defining function), you may have noticed that the call log on your Android device is limited to 500 calls. For the majority of people, this wouldn’t be an issue at all, but if you are one of the few people who actually wants to know the details beyond your past 500 calls, or if you’re simply up to try something new, there’s a tutorial that teaches you how to remove this limit.
Written by XDA Forum Member pollob666, the tutorial teaches you just exactly where in the code this restriction is found, and what you need to do to change or remove it. It’s a rather simple process requiring the decompilation of framework.jar and some smali editing. This has been tested to work on the Sony Xperia V and TX, running either the official ROM or OmniROM, although because of its simplicity, other ROMs and devices, both Xperia or non-Xperia may work as well. Be sure however, to make a backup in case things happen to go wrong.
This function can also be achieved via an Xposed Module, but it’s never a bad thing to take the manual way of modding, especially for those just learning the ropes. If you are interested in giving this a crack, head over to the call log limit removal tutorial thread for more information.
