This is a problem at Lenovo's end impacting many phones. Even, I was facing this problem with my Lenovo P2. But system update worked fine yesterday. Apparently, their servers have been down. They are receiving a lot of flak on the Lenovo forums. Some people have found ways to manually update the firmware using computer and some tools. You should be able to find this on googling. Or if you are like me, just wait till the issue is resolved and you will get it OTA.

Just received mine (Lenova P2) today from Flipkart.
Put in a Jio-sim and did the nougat updates.

After a few minutes of usage, the phone starts rebooting on its own.
I tried many settings, and various things I found on the net, but can not solve it :Frustrati.

Raised a complaint on Flipkart. They asked me to put it on charge for three hours (though battery is already at 100%) and retest it again.

Hope they give me a replacement if it is not solved, I like the phone.

Experts, please advise.

My almost two year old Samsung S6 Edge has been performing flawlessly. However, since a month or two, I've noticed that it's become extremely sluggish. Even the TrueCaller dialer & Google Calendar have a lag - that is so annoying as these are frequently used functions.

Is it because of the OS updates, and that newer software is meant for more powerful phones? My phone is set to update automatically (for security).

What can I do to make it quick again?

Thanks!

Your s6 is still powerful enough to handle these mundane tasks even though it's 2 years old. It can easily run Android 7 and even Android 8 when it comes . A simple factory reset should bring back those speedy days, that is what I would recommend.

This is quite a common scenario with touchwiz phones. According to me, you have two options.

1. Backup all your data to your Google and Samsung accounts. Perform a hard reset and then restore all the data you need.

2. Better option for creating a new life into your phone would be to go through Xda forums. Root your device and install a custom recovery.
Install Titanium backup and backup all your apps. Then install a new Custom Rom via recovery. When the new os boots up, login to your Google account and install titanium backup. Then restore all your previous apps.

Your pick.

I have also bought one Lenovo P2. Its home button is always hot. Is the case same with other P2 owners? I have contacted flipkart, they said they will be sending a "Product specialist". Their customer care and lenovo customer care is always trying to misrepresent it as a device heating issue. But its not the entire device but only the home button(which also has fingerprint scanner) that gets hot. One product specialist also called me and said that its heating because the scanner is in front :Frustrati as opposed to other devices where it is in the back.

Most of the colleagues have/had Samsung phones and this seems to be pretty much standard in Samsung devices and it starts at year 1 or 2, it'll start much sooner if the apps installed are numerous (50+) and usually its to do with a optimizations defect which will need more than just tweaks.

You can try a factory default reset however you will have to spend close to 4-5 hours to get back the phone as it was before the reset (installing apps, choosing wallpaper, overall phone behavior setup etc), so you could do the following which are much simpler :

1) Uninstall apps that aren't much necessary or haven't been used in long.

2) Analyze apps that are hogging processor resources and uninstall them (AVG Protection if installed will point to such apps).

3) In Developer Options you can set Background process limit to 4 or less (this might not be advisable if there are too many apps that are required to function, I fortunately have ZERO apps on the phone). In the same menu you can set the animation scale/transition scale to lower values (0.5x or off) so that the GPU rendering has less pressure and can free up the overall resources.

4) If there are too many shortcuts on home screen you can try reducing them to 3-4 (not kidding, these too cause lag overall because it takes up processor usage, every bit might help)

5) A run of CCleaner to analyze RAM usage, identify waste files and clearing history will help heaps as well, if not already done.

If all the above fail, then factory reset it is, but those will remove the Contacts, Photos and other personalized information that are stored in phone memory so a backup is needed.

Samsung has a in built app called Device Manager. Run it and click on Fix button.

Boot the device in to recovery, by pressing volume up, home and power buttons together at the same time.
After you enter recovery, select clear cache partition.

Verify if there is an improvement after the above two steps.

If there is no improvement, sync all your contacts with Google. Take a whatsapp Backup. Sync all your photos with Google photos. backup your sms using any app on the market and re-install the firmware using Samsung Odin.

After installing the firmware, during setup Google will prompt you to restore the apps or setup as fresh device.Select fresh device, so that any unwanted apps that were installed in the past will not be installed again. If you select restore, expand the section and review the app list and unselct any unused and unwanted apps.

Good Luck !!

Thanks! The only downside is that customising the phone to my preferences will take a good couple of hours. Was hoping for something simpler, but will do this if nothing else works.

Really? Why so? Do they pick up a lot of junk with time?

LOL! I know very little about ROMs. This is like asking the average Joe to get an engine swap on his Dzire :).

First thing I did when it started getting sluggish. Didn't help.

Damn dude, I just did this and the phone feels quicker clap:. Any downside? Thank you.

Done!

On my laptop & phone - both - I love simple home screens. No clutter at all.

Done.

Done!

Will watch it for a couple of days. If the sluggishness comes back, I'll grudgingly put it through a factory reset. Intend to use it for at least another year, so it might be worth the effort.

S6 edge is still a capable phone. Many people I know in my office have in fact bought brand new S6 edge at mouth watering prices even though S8 Plus is now available and they are planning to keep the phone for at least next 2-3 years.

If with current measures that have been taken, you still feel sluggishness, a simple factory reset will do wonders for your phone.

Also I suggest you to go to settings- apps and clear cache of few apps. The cache holds lots of data sometimes and causes them to be slow.

I believe just like why we should keep our cars beyond 5 years, we should also have a thread on why we should keep our phones beyond 3 years ;) ; probably I will start one:D.

Before a factory reset I would suggest trying what F150 mentioned. Wiping the cache partition following the steps above in his post.

However with Android and majorly with the Samsung bloatware the bets thing is to do a factory reset.

Newer versions of android are easier to reset and restore if you backup everything to Google. You get the phone almost same as before once u login to the accounts. Atleast that's how it was on my Nexus 5X.

Great! I had a feeling it might help, and no there is no downside, if the phone doesn't have too many apps that hog the processor all the time then in fact it should even improve battery life by over 20%!! Please do note that if you restart the phone you've to again enter the background process limit as it'd be reset to default (no limit).

And as mentioned above, I agree with the fact that certain apps store WAY too much cache (aka personal information which I find creepy).. and the top 3 culprits are as below :

- Chrome > This little software has enough information on everything we do, cookies, searches, YouTube visits, just about everything.. I did a bit of cobweb dusting today after long and found that Chrome has 200+MB cache LOL.

- UBER > This little trojan stays in the background (unless closed) and saps the resources including battery and occasionally activating GPS (yes it comes and goes and not just on a trip) and I found over 150MB cache in it today.. yikes.

- OLA > Is the Indianised version of UBER so is another trojan, luckily I uninstalled it long back, in any case UBER is the lesser of two evils and is available all the time.

- FB > I try to fiddle with colleagues phones upon their request (Samsung) and one woman's phone started flying when FB was deactivated.. albeit temporarily. Samsung's own bloatware is innumerable sadly.

Android is an OS which seamlessly enables a bunch of legalized malware to operate on the system and stay open (how hard they make it to close apps, rather the back key only takes us to the home-screen) and one has to go to the opened apps section to swipe them close and before we realize there are some 10 apps always open. Its sad that Nokia was never appreciated for its ease of use, ruggedness and security features.. smart equals oversmart when it comes to phones.

Here's my take:
a. OEM updates are pointless these days with Google Play Services making sure the underlying ecosystem is secure (link). Thats all I care about, honestly.
b. OEM updates contain updates to *their apps* and the core Android software. Honestly, leave the android nuts aside, can any common man tell you the difference between 5.1 and 6? 6 and 7? 7 and now 8? It has evolved to the point where the android version doesn't matter. Most people barely use the pre-installed software anyways, except for the initial data migration.
The only certain outcome of dutifully installing non-Nexus/Pixel updates? Planned obsolescence.

That being said, my STRONG recommendation would be:
a. Factory reset.
b. If that doesn't improve things, then use the appropriate software (my S3 used Odin) to flash the original OS version it came with, or the very next one (my personal approach). Turn off all updates including to bank apps - I find that they will simply stop working if there's a big security update.

To reinterpret the age old maxim -
If your Android ain't broken don't upgrade it.

Of course, this advise is battle tested on a statistically significant n=1 sample set, so your mileage may vary! You've been warned!:uncontrol

PS: Don't install ROMs. You need an appliance of a phone, not a temperamental cranky device!


On a side note, LG had the amazing V20 on sale for 30k. I almost picked it up except for the infamous bootloop reported on a few forums. What is the opinion of members here? Its back up to 35.5k, but I'll wait for the next sale!

At least 3 years agree:. When we use our 50 - 80k laptops for 5 years, I can't see eye to eye with those who change their 50k phones every year. A good cover also greatly helps in enhancing the phone's durability.

Thanks! Dark.Knight's tip of limiting the background processes to 4 has worked wonders. The phone is flying again.

Now that you mention it, I did feel that the battery ran out sooner on some days.

Will do, thanks!

I only update for security, just like I do my Win7 laptop. No need to?

Will do if things get sluggish again, but things are fantastic now. Been a day, and there's absolutely no sluggishness.

rl:

Yeah man. Don't know anything about ROMs either.

That's exactly what I posted - unlike Win7 where security updates can be individually selected and prioritized, on Android, the OEM update is a bundle. Mostly changes to softwares that you cannot feel - the only perceptible change is a slower phone over time!:Frustrati

Further, like I said, Google knows that terrible OEM updates (esp chinese mfrs) are the name of the game. Hence, they simply abstracted the core security protocols / services into google play services. That is silently updated (read without your permission) automatically. Hence the concept of security updates on Android doesn't exist!

Note the silent update written there - hence no inputs required from your side, unless you're so tech savvy you want to disable those updates.
