Re: LENOVO TAB 2 A10-70 lollipop issues report everybody.

2016-03-10, 21:19 PM

I got this tablet today, and it would be perfect, except for the audio. With headphones in, at low volumes, there is a kind of crackling/distortion/electrical type noise.

 

When I first started the tablet I updated to lollipop a10-70f_20151222. I didn't test the audio before updating.

 

I thought it might be hardware, but the one time I don't get any kind of noise, and the audio sounds near perfect, is the audio-visual demo for Dolby Atmos. For some reason I get no crackling here. Yet if I open up youtube, soundcloud, or a radio app, the crackling and poor quality audio comes back.

 

I've tried disabling google play music, then restarting but no luck. I tried resetting the device, but no luck. I tried force stopping the dolby apps (disable option is greyed out), but no luck.

 

The fact that the audio is perfect for Dolby Atmos means it is a software issue I guess?

 

Are there any other possible fixes?

 

I'm not sure about rooting/going back to kit-kat, seems like it might be better to just return this to amazon.

If you have audio issues, open the Dolby app, and select the "Custom 1" or "Custom 2" preset on the left side. That should disable all of that sound "improvement" crap.

 

Make sure that none of the three switches at the bottom are activated (Surround Virtualizer, Dialogue Enhancer, Volume Leveler).

 

If you enable "Volume Leveler", it'll give you a good loudness boost, but can lead to unpleasant digital distortion (might be the crackling you hear).

Quelle est la solution? Le fait que vous avez résolu le problème ne contribue pas à des lecteurs à moins que vous postez la solution .

Unless you are saying the solution was that you used to have a bad wireless access point/router.

Unfortunately that has nothing to do with normal wifi problems in Tab 2 A10 Lollipop which some people report.

I recently bought a Lenovo 2 A7-20F tablet. I came with Kitkat but gave an option to upgrade to Lollipop. I immediatley applied the update on the brand new tablet. After successful update I made it a point to factory reset it before starting to use it. I find absolutley no problems with the tablet and OS update. Everything works as it is expected to. 

 

For major updates, it is always better to do a clean install than on a system that has tons of apps and customizations. This method of resetting before and after update solves almost all reported problems. Most of the times, it is ignorance that causes trouble more than anything else.
