Galaxy Note flickering & switch-off issue - solved.

My one year old Samsung Galaxy Note 1 started to exhibit some strange behavior last few months.

When I use some camera applications or such other applications, suddenly the phone's screen starts to flicker resulting in the phone getting switched off.

When I switch on the phone, battery mostly shows 1% charge.This was very strange as before getting switched-off, there were instances were I had more than 80% charge in the phone.
If I again restart the phone, the phone shows 60% or so charge.It was very odd.

After the flickering and switch-off issue because very frequent, I searched in net and found that many had experienced this problem.

I faced another issue, my 32GB SD Card became read-only.Nothing could be saved in it.Seems because of the frequent switch-off while the card was in use, the card got corrupted.

When I checked my phone battery,I noted that it had slight bulge.So I decided to buy a new battery.

Went to Lulu Mall, Kochi and purchased a new battery.Rs.1599.With the new battery the flickering and switch-off issue is resolved now.

I also had to purchase a new 32GB SD Card.Rs.1500/-.

So I guess if any body else has this issue, a new battery is the only solution..
Check the battery, if there is even a slight bulge, replace the battery with out much delay.A faulty battery can even explode.So please be careful.

After some analysis, I found out the possible reason why my phone battery became faulty within a year.

Most days before going to sleep, my phone charge will be almost getting finished.So I used to plug-in my phone before going to sleep.So the phone was in charge mode the entire night, resulting in over charging and the battery getting corrupted.

Now I understood that this should never be done - once the phone is fully charged, unplug the charger.Also, once charged, better to recharge only after atleast only 20 to 25% charge is remaining.

When should you consider NoSQL databases?


SQL and NoSQL solutions are tailored towards very different types of workloads.

NoSQL solutions offers Higher performance, can handle Higher Volumes of data, is more scalable and is not tied-up to any standard query language - as compared to SQL solutions.

If rapid, agile development or high performance are of high priority - then NOSQL can be preferred.

However, if dealing with data sets that are likely to remain relatively stable in size, or have slower, more predictable growth patterns, then stick to non-relational database solutions.
